Exporting a HDV quality loss less movie

Hi
How to export a movie shot with a Canon HV20 and edited with iMovie HD with full quality settings ? is QT HDV 1080i25 the best way ?
Thanks

****, the Quicktime HDV export plays actually very slow and flickrs too much and doesn't play with any software but quicktime....

Quality loss: final movie has bad details

The title says pretty much all my problem, but first off let me describe my videos.
Skip to the underscore part for the direct question.
I used a clip I recorded from a flash animation from the web for my first part, and a 2nd one for the next part of my video.
Since I am experiencing this time, I decided to try making the final video in a lossless quality compared to the originals.
So, I "filmed" and encoded with the Apple FCP Uncompressed 10-bit 4:2:2 (to preserve full color gradatings). These are my controls video, I refer to them as lossless in my experiencing.
I finished making my movie in iMovie and then rendered it with Expert Settings, and I asked for a Quicktime (container) with Apple FCP Uncompressed 10-bit 4:2:2.
The problem is, the file is of much worse quality just by looking by a naked eye, and the file size is worse. I used the same codec as for input (both audio and video).
The input data rate: 165.32mbits/s
The ouput data rate: 199,97mbits/s
Could someone help me understand how come there is visible quality deteriotation despite having used the same setting? Clearly, a parameter of iMovie or iMovie itself is the direct cause.
I would appreciate any hint comments or suggestions, thank you.
Edit: I could show a screenshot to show what kind of deterioration I mean, but I don't know how to post it here.
Edited for a typo. there's probably more.

If your original footage is DV and you're using iMovie 08 or 09 then your problem is the same that the rest of us experience, mentioned in both iM09 & iDVD threads.
The root cause relates to iM08/09 adopting 'single field processing' used during the DV export process. It appears that Apple have lost interest in supporting DV format. I suggest that like a number of us you give Apple some negative feedback about it.
The problem and a protracted workaround is covered in this massive thread (99 A4 landscape pages if you print it!). It's a pleasure to read (when compared to ripping your finger nails off with a pair of bull-nose pliers). Steve Mullen PhD explains a process to deinterlace DV while converting to AIC etc which apparently overcomes the problem:
http://discussions.apple.com/thread.jspa?threadID=1882630&start=0&tstart=0
I'm yet to try it myself as I only read it last night.
I used to use iM HD on an iBook and never had a problem. Recently upgraded to a MacBook Pro and iLife 09 and then all the trouble started when I made my first movie from MiniDV tape. After three calls to Apple Support which got me nowhere I found a pile of threads in the Discussion Forum with the same grievance.
Another suggested workaround is to go back to iM HD/06 but I wanted iM 09 for the snazzy features like Dynamic Themes and Travel Maps etc so going back to iM HD is not a good solution for me.
Good luck.

Quality loss from .MOV to .AVI

Not quite sure what is going on here. When using QT Pro to export from .MOV to .AVI, the quality is significantly degraded. Any ideas why this is?
Thanks!

Any ideas why this is?
Both AVI and MOV files are generic containers so compare the codecs and data rates. Are the codecs used of similar or different levels of efficiency? If of the same level do they have similar video data rates? If not, did you increase the data rate to make up for the differences in encoding efficiency?

Audio lag when exporting 90min HDV footage as QT movie via FCP6

Hy Guys I desperately need your help!
Ive exported a 90min QT movie from an 1080i50 HDV project in FCP6 & found that the audio progressively "lags" as the clip plays.
At the start of the clip the sound is in sync with the video but by the end it lags nearly 15 seconds behind the video!
The footage had captured perfectly & everything works fine in the timeline & is rendered properly.
I've checked everything I can think of (settings on timeline are the same as the export settings - audio rate is 48KH, 25fps in both etc (I'm based in the UK)but getting no joy at all.
Initially I exported the footage using the "export quicktime movie" option, set to "use current settings", as a "self contained movie", & un-checked "re-compress all frames" option.
(The intention ultimately being to import the file into Compressor 3 to produce M2v/Ac3 files & then import them into DVD studio pro to produce a PAL anamorphic 16:9 SD-DVD.)
Since that didnt work however, Ive tried all sorts of different settings for both timeline & QT export - the only thing I havent tried is exporting it totally uncompressed (should I use 8bit or 10 bit??).
I'm a bit wary of that as It will take 12-14hrs to do so & use up an awfal lot of space.
The footage itself is of an action horror feature - so LOTS of quick cuts, whip pans & transitions.
I'm using a brand-new rented Mac G5 so I have no idea what drivers of service packs have been added - but i think its pretty well serviced (its VERY stable).
I'd be really grateful If you can get back to me with a solution on this as - no joke - my Job relies on this getting solved PDQ !!!!
Many thanks
Mike

Exporting a self contained Quicktime movie does not cause any compression to the actual images.
When using QT movie export FCP copies each frame of your finished movie and create new ones out of any transition between original media.
Editing HDV can require extra time indeed as it needs to be conformed after you finish. I would try to send the movie straight from the timeline once rendered. If you want to check out the result why not copy a portion of the edit on a second identical sequence and send it to Compressor.
Testing is always a crucial part of the process.

Quality loss after exporting 1280 x 960 30fps footage

Hello everyone,
Everytime I edit and export footage shot with my GoPro camera (1280x960p, 30fps) the quality gets a little less. Very frustrating as I am clueless after a long time of looking for what I'm doing wrong..
I use Premiere Pro Version 4.2.1
Sequence presets:
General
Editing mode: Desktop
Timebase: 29,97fps
Video Settings
Frame size: 1280h 960v (1,0000)
Frame rate: 29,97 frames/second
Pixel Aspect Ratio: Square Pixels (1.0)
Fields: No Fields (Progressive Scan)
Export settings:
Format: H.264
Preset: Custom
TV Standard: NTSC
Frame Width: 1280
Frame Height: 960
Frame Rate (fps) 29.97
Field Order: None (Progressive)
Pixel Aspect Ratio: Square Pixels.
Has anybody got an idea what could help here?

Thanks for the replies guys, but unfortunately the problem isn't really solved yet..
I tried checking the maximum render quality, but that only resulted in my laptop not being able to smoothly play the exported video.
Filming with the 1280 x 720 setting is possible, but then the footage just doesn't look that sharp.. (as I can't film in 60fps, I got the first GoPro 960).
I installed Cineform and converted a little test video to AVI. This resulted in an export video without quality loss, but the conversion with Cineform took way too long for it to be a practical solution cause I edit a lot.
At last, Abhishek Kapoor, I couldn't find the video setting you're talking about to increase the maximum bitrate.
Any other ideas that might work?

Exporting a movie on a G4 without quality loss

I do not have idvd on my PowerMac G4. Can someone explain how to export a movie without quality loss? I tried the various options in the dropdown menu but they seem to cause distortion.
~Thanks

Without quality loss ... what format did you start with? What format or delivery media do you need to output? If you're going to DVD-Video, there will be a quality loss due to the amount of compression needed.
You can output a QT movie (self-contained, using current settings, do NOT recompress!) that should be an exact duplicate of your sequence.

IMovie HD6: HDV to AIC to HDV... quality loss?

Hi All,
I'm curious, when I use my normal workflow (HDV to AIC (imovie 6) to HDV), does it lose quality?
If so:
* Is there a way to avoid this?
* How much quality is lost? Is there a visual comparison available?
Thanks for any input!

Dear catspaw,
Here are my thoughts, based on my experiences, and what I think I understand of all this..
1. Standard-definition DV (those little tapes, or the larger 'broadcast' tapes) is pretty much compression-free ..we-ell, strictly speaking there's some, but relatively little, compression used in DV. It looks perfect, although it is slightly compressed. The material recorded onto tape - and imported into iMovie - contains every frame which the camcorder optics see. So editing it is simple: all the frames get copied into iMovie, and you can chop out, or insert, anything you want. Using iMovie HD 6, or earlier, you can then copy the edited material back to a DV camcorder ..all the frames get shuffled out of the computer and back onto tape again. (You can't do that with iMovie '08, as it has no option to Export to Camcorder.) What you see in iMovie - after importing from a DV camcorder - isn't exactly the same as what you've imported, because iMovie runs on a computer, and uses a computer display, and that generally shows complete "progressive" frames of video, whereas a TV ..or TVs with cathode ray tubes; precursors to the latest LCD or DLP or plasma TVs.. will generally show interlaced 'half-frames' one after the other, each comprising half the TV picture, but shown in such rapid succession that they blur into each other, and our brains see a succession of complete frames.
(..Here's a good visual representation from one of Adam Wilt's pages:
..There are two 'fields' of video, each made of half the entire number of lines down the screen, superimposed on each other, and blending into a full frame of video comprised of all the lines. That's what happens on a TV screen when the interlaced 'fields' of video blend together..)
So standard-def DV is really plain and simple, and there should be no quality loss after shooting, importing, editing, exporting.
2. Hi-def. A can of worms. There are several different varieties of "hi-def". What we're working with in our 'amateur' movie program, iMovie, is generally the HDV version of hi-def, or the AVCHD version. (And a few people may be working with JVC's version of 'progressive' frames, but with a lower total number of lines down the screen: 720p, instead of 1080i. 720p has 720 pixels down the screen, and records and presents an entire 'progressive' ..one-line-after-the-other.. frame of video at a time, whereas 1080i shows 1080 pixels down the screen, consisting of half that number, 540; all the 'odd-numbered' lines.. at a time, immediately followed by the other half ..the even-numbered lines.. slotting in-between the previous lot. That repeating pair of 540 'interleaved' lines gives a total of 1080 interlaced lines in every frame. Movement appears smoother using 1080i (..after all, the picture is refreshed twice as often as with single-complete-frame 'progessive' video..) but may not look as super-sharp as progressive video, because at any moment there's only half the total information of a frame onscreen. 'Interlaced' video is smoother, and any action flows more "creamily", whereas 'progressive' may be considered 'sharper' (..it is if you freeze a frame..) but more jerky.)
So our 'amateur' hi-def movies may be recorded as HDV, AVCHD or some other similar format. 'Professional', or broadcast-intended, hi-def may consist of several other non-amateur formats, some of which are completely uncompressed and require extremely fast links between the cameras and recording equipment, and massive-capacity hard discs to capture and edit the huge quantity of data which such cameras..
..deliver ..for $150,000. Or here's a remote-control broadcast hi-def camera for (only) $7,995..
(..Tell me if I'm boring you..)
The hi-def cameras which we're more likely to be using..
..record compressed video in MPEG-2 format, or H.264, or some similar codec. The idea behind HDV was that the companies which make 'consumer-grade' (amateur) camcorders wanted a method to record hi-def - with about 4x the data of standard-def - onto the little miniDV tapes which we were all familiar with. So a method was found to squeeze 4x the data onto a tape which normally records standard-def DV data at 25 megabits per second. The method decided upon was MPEG-2 ..the same codec which is used to squeeze a two-hour Hollywood film onto a little 4.7GB capacity DVD. (Bollywood movies, as distinct from Hollywood movies, tend to be three hours long!)
If MPEG-2 was good enough for the latest cinema releases, in nice, sharp, sharper-than Super-VHS form, then it was thought to be good enough for 'domestic' hi-def recordings. The only awkward thing about that - from an editing point of view.. (..but which of the camcorder manufacturers are seriously interested in editing..? ..they primarily want to sell 'product' which - according to their advertising - is terrific at simply recording and playing-back video. Like car advertising shows you how wonderful cars are to sit in and for travelling to places, but the adverts don't tell you about how tricky it may be to get into the rear sidelights and replace a blown bulb..) ..is that in HDV there's only one 'real' frame for every 15 frames recorded on the tape. The other 14 are just indications of what's different between the various frames. Therefore, for editing, the 'missing' frames must be rebuilt during import into iMovie.
Steve Jobs heralded 2005 - at MacWorld, you may remember - as the "Year of HD!" ..It became possible to import and edit hi-def in iMovie ..that is, the HDV version of hi-def, not the uncompressed 'professional' broadcast version of hi-def, of course.. but ONLY with a fast enough computer ..and many weren't fast enough to import and convert HDV to editable-format in real-time (..no mention of it being the year you would import at half, or a quarter, or an eighth, real-time ..ugh-ugh).
So HDV gets converted to AIC to make it editable ..and then what d'you do with it? ..Few (none of them?) HDV camcorders let you import HDV back to tape from iMovie. No Macs had/have Blu-Ray burners ..although you can burn about 20 mins of hi-def onto normal DVDs with a Mac's normal inbuilt SuperDrive DVD burner with the appropriate software ..DVD Studio Pro, or Toast, etc.
(..Once again, there was some omission from the hoopla ..yes; you can import HDV! ..yes; you can edit HDV! ..er, no, sorry; no mention that you can't burn a 1 hour hi-def home video onto a hi-def DVD with a Mac ..iDVD would/will only burn in standard-def, and there are no Blu-Ray burners built into Macs..)
Then came AVCHD (Advanced Video Codec; High Definition). This compresses video even more than HDV (whose compression is pretty much invisible, and is in regular use for broadcast material) by using a different method. And along came progressive hi-def recording, trying to supersede HDV's generally 'interlaced' 1080i hi-def.
But the problem with progressive, non-interlaced AVCHD is that if there's rapid movement in a scene - if you move the camera, or something rapidly crosses the picture - instead of the "creamy flow" of interlaced video, there's a jerky lurch from one frame to the next. And with the added extra compression of AVCHD this jerkiness can be (..to my mind..) even more horribly evident.
Anyway, unscrambling ..and then re-assembling.. hi-def interlaced MPEG-2 HDV is pretty much invisible - to me, anyway. The video looks sharp, moves smoothly, looks 'true-to-life' and doesn't have terrible artifacts and jerks.
Unscrambling ..and then re-assembling.. hi-def interlaced or progressive AVCHD (..which is sometimes described as MPEG-4 or H.264..) - I know that you know this, but I'm also writing for others here - isn't quite as simple as doing the same for tape-based MPEG-2 hi-def HDV. Here's all the gobbledegook about what AVCHD can consist of.. http://en.wikipedia.org/wiki/MPEG-4_AVC
..Oh, and here's a bit about the "usability" of AVCHD: http://en.wikipedia.org/wiki/AVCHD
There are many more 'varieties' of encoding in AVCHD than in 'simpler' hi-def, such as HDV. There's less data sent in an AVCHD data stream than HDV (..AVCHD has jumped from 17MBits/sec to 24MBits/sec ..just below HDV's 25MBits/sec..) so the video is more compressed than HDV. And there are all sorts of video formats (interlaced, progressive, HD, 'Full' HD) which are recorded by different cameras under the all-embracing 'AVCHD' label. iMovie - or a Mac - has to work much harder to unscramble and convert the more-compressed AVCHD format(s) than uncompressing HDV. And has to work harder to compress the output of iMovie to H.264 (an AVCHD codec) than when re-compressing to MPEG-2 (the codec for standard-def DVDs and hi-def HDV).
To - finally! - come back to your question "..is there therefore no advantage in using DV tape-based vidcams for editing purposes.." I'd say that there ARE advantages in using tape-based vidcams for editing purposes ..using your two categories:
1. Non-hi-def tape-based DV is ..to all intents and purposes.. lossless. And the material can be imported in real-time, and be output - with no loss - in real-time, too, using any Mac from an old G3 onwards. Importing non-tape material into iMovie ..e.g; miniDVDs, or chip-based, more compressed video.. is more long-winded, and generally has to go through various external bits of software (..e.g; MPEG Streamclip or somesuch..) to put it into a format that's editable in iMovie. AVCHD can, theoretically - as 'AVC', without the 'HD' - be used for recording in standard-def, but there are currently few AVCHD camcorders which are built to record standard-def video as well ..there is the Sony HDR-SR12. But only iMovie running on an Intel-powered Mac will decode AVCHD, apart from separate standalone Mac software such as 'Voltaic'.
2. Hi-def tape-based recording IS an advantage on anything that's less than the fastest, or highest-powered, of Macs, because it needs less "horsepower" to "unpack" the compressed data and to get it into an editable format through recovering, or rebuilding, the necessary individual frames. I think it's an advantage in every case, as not only can tape-based hi-def be edited on older, slower Macs (including pre-Intel Macs) but also:
(a) HDV data's less compressed, and so motion is generally expressed - currently - more "fluidly" than with the more compressed hard-disc or chip-stored AVCHD,
(b) HDV original material is "self-archived" onto its tapes ..you don't have to "empty" a camcorder's hard disc or memory chips onto something else - such as a separate hard drive - in order to re-use, or continue using, the camcorder: you just drop in another cheap 1-hour tape,
(c) Tape-containing camcorders tend to be heavier, less lightweight, than fewer-moving-parts chip-based AVCHD camcorders. They're therefore inherently less "wobbly" and don't tremble so much in your hand ..that gives smoother, less "jiggled-about" recordings ..even taking into account the stabilisation built into most camcorders,
(d) Tape-based camcorders are less likely to lose an entire 'shoot' by being dropped or mis-treated. Material already recorded onto a tape will not be damaged if you drop the camera and its tape-heads thereby become misaligned. The data can be recovered by simply ejecting the tape and popping it into another camcorder. If a hard-disc camcorder is dropped, subsequent head misalignment may mean that all data already on the hard disc is irrecoverable. If a memory chip becomes corrupted, all data may similarly become irrecoverable. If a tape becomes damaged, it's usually only a few seconds' worth which be lost. (..I dropped a tape-based camcorder in the sea when I was trying to get shots of waves coming in onto the beach from an offshore viewpoint, and a wave washed right over me and knocked me down. The camcorder was a write-off, but I managed to prise the tape out, and recover the 30 minutes of movie I'd already recorded. I don't really want to test it, but I have doubts about whether I'd have been able to recover my video from a similarly-drowned hard-disc based camcorder ..maybe, in the interests of factual objectivity I'll try it some day with an old, no-longer-used 2.5" hard disc..)
(e) AVCHD camcorders - unless you're looking at 'semi-pro' or professional 'cost-a-plenty' record-to-chip camcorders, or that Sony HD12..
..are generally built for "point-and-shoot" amateurs. This means that AVCHD camcorders generally do not have the assortment of manual controls which you find on most tape-based HDV camcorders (..because the camcorder makers also aim, or aimed, HDV at low-cost broadcast users, too). There's usually far greater flexibility and more shooting options (shutter speeds, exposure, audio handling) on tape-based HDV camcorders than can be found on AVCHD camcorders. If you're just pointing and shooting, that doesn't matter ..but if you want to shoot good-looking video, there are generally - and it is a generalisation - more adjustment options to be found on a tape-based camcorder than on a chip-based or hard-disc AVCHD camcorder. In my experience - yours may be different - people tempted by AVCHD camcorders tend to buy (..and manufacturers tend to publicise..) high pixel counts (like "Full HD 1920x1080") and that magic word "progressive" (perhaps because it has the flavour, in English, of "futuristic" or "more advanced") rather than their being concerned with choices of apertures or shutter speeds and the clearest representation of what the camcorder's pointing at.
In summary ..at last!.. "..is there therefore no advantage in using DV tape-based vidcams for editing purposes.." Yes; the advantages, I believe, are that HDV converts fast into AIC for editing; my perception is that HDV delivers smoother action (onscreen movement) than AVCHD; and with a suitable deck..
..HDV can be returned back to tape, whereas it's more long-winded and needs more subterfuge to export AVCHD back to a chip, or a camcorder's hard disc, for in-camera replay ..and thence out to an HDTV.
As always, these are simply my opinions ..others may disagree.

Significant quality loss and jagged diagonal lines when exporting from FCP

I've been working on this problem for several days and I'm going insane! Every time I export my movie from Final Cut, there is a significant quality loss. It is most noticeable in two ways: diagonal lines become very jagged (looking somewhat like diagonal lines in an older video game -- more a diagonal sequence of blocks); also, in some areas such as faces, the colors get a little blurry and there seems to some "pooling" of colors around the edges of the face.
I'm pretty sure the problem's not in capture: the Quicktime clips that I captured from the camera are all pristine. When I play them in Quicktime, I can blow them up several times their original size, and they maintain their sharp lines. (I also Reverse Telecined them all with Cinema Tools, if that's relevant.) I also know the problem's not just my computer monitor; when I play these movies on my external monitor and TV, they look bad too. The clips look bad after I bring them into Final Cut, and while I'm editing, but at first I figured that was because Final Cut sometimes doesn't show full resolution in the timeline. Still, when I export, the quality of the original captures just isn't there.
Some details:
Captured from 24A progressive, Sony HVR V1U HDV.
Using Final Cut 6.0.1, Compressor 3.0.1, Quicktime 7.2.0, OS 10.4.10 (all the most recent versions I believe).
I've exported in many different ways: using Compressor (and have tried a number of different settings: the DVD Best Quality 90 Minutes default Setting, as well as using a variety of bit rates from 3.0-8.0, One pass CBR, Two pass CBR, Two pass VBR, Two pass VBR best; Video Formats NTSC, HD 1440x1080...I have tried many combinations. Regardless of the size of the m2v created, the files seem to have the same problem over and over. I've also tried exporting from Final Cut as a Quicktime Movie and with Quicktime Conversion. Same result. I also tried using different compressors with my Final Cut sequence: Apple Intermediate Codec (which I used when capturing -- you have to with the Sony HVR), HDV 1080p24, HDV 1080i60, Apple Pro Res 422, H.264...
What's happening? Why is Final Cut turning my nice pristine captures into jagged foulness? What can I try that I haven't yet?

Welcome to the forums!
Unfortunately, you seem to have tried everything I can think of, and I don't have the latest versions of FCP to know if it is a bug. However, in the off chance that you haven't given this a shot:
Take a problematic 10 second section of your timeline (set in and out points) and the Export -> Quicktime (not QT Conversion) and make sure that you have it on Quality settings that you captured, and select the "Make Self Contained" box.
Look at that in Quicktime and see if it's bad. If it's not problematic, use that video file in Compressor for your render.
Hope that helps!

Import Analog 8mm Home Movies thru ADVC 110 NEED LOSS LESS Format -IMovie8

Works fine however Import defaults to an .mv4 file.
Is this a Loss Less Format and if not is IMovie8 capable of a Loss Less type format like IMovie dv or similar.
if So how do I change the setting to get the highest quality import of my old analog 8mm home movies ?
Thank You
Daniel

Hi
You don't use iMovie'08 or 09 but iMovie HD 6 or FinalCut.
iMovie'08 & 09 discard every second line when importing interlaced video.
(Or when exporting it out to DVD at least - Not my favourite for intelaced (normal TV/and miniDV tape) material)

Tif export quality loss

hi,
i exported a tif sequence from a mp4 in premiere (cs6) to do some compositing on it. the exported images look the same but when doing some color correction on it the tif sequence reveals that it's in lower quality.
the left side is the tif export with significant less detail.
i also tried ae with color management but i always had the same problem.
rendering with 'use max depth' and 'use max quality' did not solve the problem.
did i miss something or is premiere processing some colors wrong internally?
(as a sidenote, quicktime player, nuke, vegas12 worked just fine)

hi,
it looks like the problem is related to mpeg 4. i did not have time to do further testing. here is the file info:
Format                         : MPEG-4 Visual
Format profile                 : Advanced Simple@L3
Format settings, BVOP          : Yes
Format settings, QPel          : No
Format settings, GMC           : No warppoints
Format settings, Matrix        : Default (H.263)
it did not occur with other videos.
the interesting thing is that the quality is fine within the timeline. but upon output there is a quality loss.
no, output is 8bit. as mentioned in the first post 'use max depth' did not solve the problem.
quicktime based applications did not have the issue.
as for the color shift problem i thought it is related to the same issue but it was something different and is fixed now. i was unable to edit the post to remove it.

Another quality loss issue: exporting

I see a lot of people have problems with quality loss.
I am importing an movie of an animated screengrab (using Snapzpro). This movie looks great - nice and sharp when viewed in QT. After importing into iMovie it's slightly blurred, notr a big deal just looks a bit "warm".
However when I export it looks bad, diagonal lines are very jagged. I've tried export at Full quality, I've tried expert settings with DV-PAL and many other codecs.
It's just about OK if I use "none", and then import into QT Pro and export with DV-PAL - what I don't understand is why I can't just use DV-PAL direct from iMovie.
Is this something I just have to put up with? Would it better with Final Cut Express?

Actually I discovered since posting the question, that the dimension is something to due with it, but too small rather than too large. I was capturing at 640 x 480 and I discovered that capturing 768 x 576.
I also think that the nature of the image is crucial. This is large scale musical notation - lots of diagonal black and white straight lines so any jaggedness becomes very obvious.
What I still don't understand is why the export from iMovie using DV PAL is not as good as the export from QT using DV PAL - I have to export from iMovie with no compression, then re export from QT Pro.
Although I,m totally ready to accept this is a human operator error, I've also seen lots of people say iMovie does degrade on importing which is why I wonder if I need final Cut Express or Pro

How do I produce the highest quality DVD from MOV exported from iMovie

What is the best method in iDVD11 for burning to DVD, an imported HD 720p or HD 1080p MOV file exported from iMovie11?
I have successfully exported a 5.5GB (66min) HD 720p MOV file from iMovie. I then used iDVD to import this MOV file and burn it to DVD. When I played the DVD the quality was nowhere near that of the imported HD 720p MOV file as played on QuickTime. The DVD also shows captions at the edge of the 16:9 TV screen instead of further inside as per the QuickTime screening of the HD 720p MOV file.
How can I improve quality and maintain borders in iDVD for the DVD output?

Hi
How can I improve quality and maintain borders in iDVD for the DVD output?
Quality.
• Use iMovie up to HD6 or FinalCut - as iMovie'08 or 09 or 11 - just delivers every second line to iDVD = less resolution
• There are no HD-DVD in real life - DVD is as standard SD-Video
• If You must use iMovie'11 then do not use "Share to iDVD" BUT "Share to Media Browser" and as Large (Not HD or other resolution - as result will suffers)
Border
• May be turning on TV-Safe area in iDVD can help a bit. ?
• If this is IMPORTANT - Then You have to re-do Your movie in FinalCut and here turn on TV-Safe area and shrink the movie area to within this. Now it will show all on an old CRT-TV - but with a black frame due to that no two CRT-TVs show exactly the same area and then TV-Safe must be less than this.
My - Un-specific notes on DVD-Quality. If You are interested.
DVD quality
1. iDVD 08, 09 & 11 has three levels of qualities. (vers 7.0.1, 7,0.4 & 7.1.1)
iDVD 6 has the two last ones
• Professional Quality (movies + menus up to 120 min.) - BEST
• Best Performances (movies + menus less than 60 min.) - High quality on final DVD
• High Quality (in iDVD08 or 09) / Best Quality (in iDVD6) (movies + menus up to 120 min.) - slightly lower quality than above
About double on DL DVDs.
2.Video from
• FCE/P - Export out as full quality QuickTime.mov (not self-containing, no QT-conversion)
• iMovie x-6 - Don't use ”Share/Export to iDVD” = destructive even to movie project and especially so
when the movie includes photos. Instead just drop or import the iMovie movie project icon (with a Star on it) into iDVD theme window.
• iMovie’08 not meant to go to iDVD. Go via Media Browser or rather use iMovie HD 6 from start.
3. I use Roxio Toast™ to make an as slow burn as possibly eg x1 (in iDVD’08 or 09 this can also be set)
This can also be done with Apple’s Disk Utilities application.
4. There has to be about or more than 25Gb free space on internal (start-up) hard disk. iDVD can't
use an external one as scratch disk (if it is not start-up disc).
5. I use Verbatim ( also recommended by many - Taiyo Yuden DVDs - I can’t get hold of it to test )
6. I use DVD-R (no +R or +/-RW)
7. Keep NTSC to NTSC - or - PAL to PAL when going from iMovie to iDVD
8. Don’t burn more than three DVD at a time - but let the laser cool off for a while before next batch.
iDVD quality also depends on.
• DVD is a standard in it self. It is Standard Definition Quality = Same as on old CRT-TV sets and can not
deliver anything better that this.
HD-DVD was a short-lived standard and it was only a few Toshiba DVD-players that could playback.
These DVDs could be made in DVD-Studio Pro. But they don’t playback on any other standard DVD-layer.
Blu-Ray / BD can be coded onto DVDs but limited in time to - about 20-30 minutes and then need
_ Roxio Toast™ 10 Pro incl BD-component
_ BD disks and burner if full length movies are to be stored
_ BD-Player or PlayStation3 - to be able to playback
The BD-encoded DVDs can be playbacked IF Mac also have Roxio DVD-player tool. Not on any standard Mac or DVD-player
Full BD-disks needs a BD-player (in Mac) as they need blue-laser to be read. No red-laser can do this.
• HOW much free space is there on Your internal (start-up) hard disk. Go for approx 25Gb.
less than 5Gb and Your result will most probably not play.
• How it was recorded - Tripod vs Handheld Camera. A stable picture will give a much higher quality
• Audio is most often more critical than picture. Bad audio and with dropouts usually results in a non-viewed movie.
• Use of Video-editor. iMovie’08 or 09 or 11 are not the tools for DVD-production. They discard every second line resulting in a close to VHS-tape quality.
iMovie 1 to HD6 and FinalCut any version delivers same quality as Camera record in = 100% to iDVD
• What kind of movie project You drop into it. MPEG4 seems to be a bad choice.
other strange formats are .avi, .wmv, .flash etc. Convert to streamingDV first
Also audio formats matters. I use only .aiff or from miniDV tape Camera 16-bit
strange formats often problematic are .avi, .wmv, audio from iTunes, .mp3 etc
Convert to .aiff first and use this in movie project
• What kind of standard - NTSC movie and NTSC DVD or PAL to PAL - no mix.
(If You need to change to do a NTSC DVD from PAL material let JES_Deinterlacer_3.2.2 do the conversion)
(Dropping a PAL movie into a NTSC iDVD project
(US) NTSC DVDs most often are playable in EU
(EU) PAL DVDs most often needs to be converted to play in US
UNLESS. They are playbacked by a Mac - then You need not to care
• What kind of DVDs You are using. I use Verbatim DVD-R (this brand AND no +R or +/-RW)
• How You encode and burn it. Two settings prior iDVD’08 or 09
Pro Quality (only in iDVD 08 & 09)
Best / High Quality (not always - most often not)
Best / High Performances (most often my choice before Pro Quality)
1. go to iDVD pref. menu and select tab far right and set burn speed to x1 (less errors = plays better) - only in iDVD 08 & 09
(x4 by some and may be even better)
2. Project info. Select Professional Encoding - only in iDVD 08 & 09.
Region codes.
iDVD - only burn Region = 0 - meaning - DVDs are playable everywhere
DVD Studio pro can set Region codes.
1 = US
2 = EU

What it turned out to be was the "quality" settings in iDVD. The total clip time was NOT over 2 hours or 4.7GB, yet iDVD created massive visual artifacts on the "professional quality" setting.
I switched the settings to "high quality" which solved the problem. According iDVD help, "high quality" determines the best bit rate for the clips you have.
I have NEVER seen iDVD do this before, especially when I was under the 2 hour and 4.7GB limits.
For anyone else, there seem to be 2 places in iDVD to set quality settings, the first is under "preferences" and the second under "project info." They do NOT seem to be linked (i.e. if you change one, the other is NOT changed). take care, Mario
TO GET IT TO WORK SLIGHTLY FASTER
• Minimum of 25Gb free space on Start-Up hard disk
• No other programs running in BackGround eg EnergySaver
• Don’t let HD spinn down or be turned off (in EnergySave)
• Move hard disks that are not to be used to Trash - To be disconnected/turned off
• Goto Spotlight and set the rest of them under Integrity (not to be scanned)
• Set screensaver to a folder without any photo - then make an active corner (up right for me) and set
pointer to this - turns on screen saver - to show that it has nothing to show

Is there a quality loss going from AVI to MOV?

I'm using QT Pro to open an .avi file so that I can trim off a little bit from the end of the video. When I do that and then go to save the file, I can only save it as a .mov file. That doesn't bother me so long as there's no quality loss. Can anyone confirm this?

one man's long is another mans....
can you do an experiment for us. Duplicate the file and count how long it takes and compare it to how long it takes to export.

HDV or AVCHD editing = processor utilization = import/exp. quality loss

Hello,
my question about processability of HDV/AVCHD Movies with iMovie. I have learned that HDV and AVCHD files are transfered in the AIC format. That should mean editig a movie would be always in the AIC format and I assume no difference whether I come from HDV or AVCHD format it should be similar demanding to the core2duo processor except initial transcoding from H264 to AIC - is this right?. When I save a movie out of iMovie do I save it in AIC or in HDV/AVCHD? Is there a quality loss transferring a movie back and forth from/to HDV/AVCHD to AIC since HDV employs mpeg2 and AVCHD employs H264 which are both compressed formats? Practically does this also mean that AIC can work as a bridge to between both formats?
Thanks for your replies to my several questions!

I have cut/pasted this from another thread where I posted it following a question from a Canon HV20 owner. The info applies to all HDV and AVCHD cams though. Might help you decide.
This comes from www.camcorderinfo.com
Compression (7.0)
The Canon HV20 (Review, Specs, Recent News, $903) uses HDV compression, a very efficient MPEG-2 codec with a fixed data rate of 25Mbps, identical to the data rate of standard definition DV compression. HDV excels in capturing stunningly high-resolution video, but it is inferior to DV in terms of rendering motion realistically, due to its dependence on interframe compression. This means that at 1080i, only one in fifteen frames is a full-frame picture, while the intervening frames are compressed in relation to each full I frame. Interframe compression is much more efficient than intraframe compression, and allows HDV to squeeze a full 1920 x 1080 picture into a 25Mbps stream, recordable to inexpensive MiniDV tapes. DV uses intraframe compression, so each frame is a fully independent picture, allowing much better motion capture. DV also uses a superior 4:1:1 color space while HDV encodes via a truncated 4:2:0 color space.
The inherent weaknesses of HDV have led many networks to deem the format sub-standard for broadcast, but it is still the best high definition format available on the consumer camcorder market. Most consumers find the stunning resolution of HDV trumps the superior motion handling of DV. A professionally lit HDV interview (or any HDV shot without too much detail or motion) can look nearly as good as footage shot in a professional HD format on a $20,000 camera. AVCHD, a new HD format that uses H.264 compression was introduced in 2006 and compresses video even more aggressively than HDV. Our tests of Canon's UX1 (Review, Specs, Recent News, $729.95) and SR1 (Review, Specs, Recent News, $1119.99) last fall show that while AVCHD video is very sharp, it suffers from grain and artifacts much more than HDV compression. The wildcard in the consumer high definition arena is a new MPEG-2 format developed by JVC, the MPEG Transfer Stream codec, which appears for the first time in the Everio HD7 (Review, Specs, Recent News, $1529). MPEG Transport Stream compresses video at up to 30Mbps, and may rival or even outclass HDV compression.
Media (6.0)
Like other HDV camcorders, the Canon HV20 records to MiniDV cassettes, the same inexpensive and widely available format used by standard definition DV camcorders. MiniDV cassettes have a run time of 60 minutes in SP mode, but can hold up to 90 minutes of more compressed LP video. Unlike the DVD, memory card, and HDD formats, MiniDV tapes are linear media so moving clips to a PC from tape is a real-time process. For anyone serious about the quality of his or her video, HDV recorded to MiniDV cassette remains the best consumer HD option available. To date, consumer non-linear video formats do not support the highest-quality video compression codices for high definition (HDV) and standard definition (DV).

Native HDV versus Cineform editing - noticeable quality losses?

Hi folks.
Is it me or Premiere CS3 feels more happy editing native HDV versus Cineform? With HDV it just renders A LOT faster and the program seems to run better (less stutter). The only downside is that it takes forever to load the project (versus Cineform) and the mastering output choices are smaller.
I really like Cineform, but in my computer it just asks too much patience(Win XP SP3 + P4 775 3.06 + 1024 RAM).
Editing in HDV, the quality is really that sacrified???? My editing routine consists of dissolves, magic bullet looks and classic effects.
What is your opinion? Thank you guys :)

Thank you Steven.
Cineform does not render only if you use their effects. But if you need Magic Bullet Looks or GenArts Sapphire the story changes. I did some little test:
HD clip 1920x1080 50i of 4:10 seconds with "Basic White Diffusion" Magic Bullet effect takes to render:
01:30 minutes in CFHD
00:50 seconds in HDV
Can I export my HDV project to Cineform in order to preserve quality? What other options do I have?

Exporting a HDV quality loss less movie
