Exporting to iDVD vs. full quality QT movie

Is there any difference in quality if you export your movie to a Quicktime movie at full quality then bring that into iDVD, versus exporting the movie directly to iDVD? I've been making the QT movies and then bringing those into iDVD. I suspect you get the same thing either way, but would like to know if there is any difference.

No, there is no quality loss. I do that all the time, especially if my original movie is lengthy or complicated because the audio begins to distort. I put the new quicktime movie into a new iMovie and use that for iDVD. I also like to place my chapter markers on transitions, and with the quicktime movie, that is not a problem.

Export a Full Quality QuickTime Movie for CD

Hello - I have an 11 min. movie, that contains mostly pics, but also some video - I will be giving it to someone to play on there computer, which will also project onto a screen, during a wedding reception. She just wants to be able to load it into her computer - what is the most effective way of doing this?
I thought about exporting to a 720x480 Quicktime movie, using Qtime Conversion in FCP, and H.264 compression - is there a better way, so that it will show the best quality? After burning the movie to a QT file onto a CD, I thought I would then give to her to download - is this the proper way to do this type of thing?
Any suggestions are most appreciated as always - thank you...

KL -
That might be fine... thing is you WANT to have her test it. Sometimes playing large files like this (yes, even at h264) can choke a pc pushing it out to a projection unit.
I like putting it back to tape and sending it full rez out of a deck or other video camera.
I never trust PCs to even play a DVD out.

Exporting full quality problem.

i shoot my movie in 16:9 on my sony camcorder. everything works perfectly in regards to editing and transfering to iDvd. the one thing i noticed that was weird is 2 days ago i made a short clip. about 5 minutes in 16:9 format. got it in and edited it in iMovie. so then i wanted to export it twice. once to put on youtube. i exported for webstreaming and it was fine. then another i wanted to export in full quality so i could send it to my brother to watch on his TV (he is in cali). but when i exported it into full quality it went back and squished it into a box format and not widescreen. so i fiddled around with "advanced" and got it to export 16:9 but the quality didnt look very good.
how can i get it to export perfectly widescreen at full quality? Thank you.
PS. I hope i make sense.

Hi
*Not knowing the origin to Your problem - General approach when in trouble is as follows.*
• Free space on internal (start-up) hard disk if it is less than 10Gb should rather have 25Gb
• Hard disk is untidy. Repair Permissions, Repair Hard disk (Apple Disc Util tool)
• Garageband-fix. Start it, Play a note and Close it. Re-try (Corrects an audio problem that hinders iMovie)
• Delete iMovie pref file - or rather start a new user/account - log into this and re-try
iMovie pref file resides.
Mac Hard Disk (start-up HD)/Users/"Your account"/Library/Preferences and is named. com.apple.iMovie.plist
While iMovie is NOT RUNNING - move this file out to desk-top.
Now restart iMovie.
• Third party plug-ins that doesn't work OK (not relevant for iMovie’08 or 09)
• Program miss-match. iMovie 5.0.2, up to Mac OS X.4.11 AND QuickTime 7.4.1 - is OK
• Program miss-match. iMovie 6.0.3 or 6.0.4, Mac OS X.4.11 AND QuickTime 7.4.1 - is OK (might work under Leopard)
• Program miss-match. iMovie’08 v. 7.0.1, Mac OS X.4.11 AND QuickTime 7.4.1 - is OK (might work under Leopard)
• Screen must be set to Million-colors
From LKN 1935. (in this case = iMovie HD (5), I tried it all, but nothing worked.
Your answer (above) has been helpfull insofar as all the different trials led to the conclusion that
there was something wrong with my iMovie software. I therefore threw everything away and reinstalled
iMovie from the HD. After that the exportation of DV videos (there has not been any problem with HDV videos)
to my Sony camcorders worked properly as it did before.
Yours Bengt W

Full Quality Exporting Problem...

I made a movie that is roughly around 12 gigs of memory. I exported the movie to CD Quality first so that it can be uploaded to youtube. The problem I noticed with the CD Quality, is that some of the frames jump a bit. However the movie plays fine...
When I try to export the project to Full Qaulity, the movie seems to export faster than it does CD Quality, roughly taking about 45 seconds fully to complete itself...
When I open the full quality movie, the first movie clip from the project plays, but then freezes at the beginning of the second one...
Is it freezing because the project is too big? Or is it something else???
In any case, how I can fix this so I can have a working full quality movie???
(By the way, I have iMovie HD)
Message was edited by: stringcheese

Actually, I figured out the problem...Apparently, every movie clip that I had changed the speed to (slowed down or sped up) froze the video...
Is there any way to fix this???

Export "full-quality" in iMovie '09.

Using iMovie HD, I used to export my footage as a full-quality QuickTime movie so I could archive it to disk and access it later. However, in iMovie '09, the "full-quality QuickTime" preset seems to have been removed.
What export settings in iMovie '09 will allow me to achieve the highest possible quality? I'd like to archive my footage to disk so that I'll always have a digital file to work with.
Thank you.

Welcome BarrenRegions to the  iMovie boards ..
no way to answer that question.. you have to compare apples with peaches.. (German proverb):
iMHD≥6 was a dv-only editor (and AIC, but this is another story...); it handles dv lossless.. frequent contributor lennart once made a test of ex- and reimporting a few dozends time the same clip = no loss of pic quality.
now iM08/09:
it handles dv not as dv internally anymore; therefore it accepts lots of other codecs (mp2, avchd, h264...).. so, depending of your source, the export can be lossy.
we have mile-long threads about that, search for posts from Steve Mullen and Euisung Lee who did research this issue +ad nauseam+
as far as I followed that discussion: there's a 'trick', to convert - after import into iM08/09 - the imports to AppleIntermediate with tools as QTpro or Mpeg Streamclip. that blows-up size, but forces iM08/09 to keep quality a 100%...
.. sorry for being less helpful, even as a 'Silverback' on this board, all that is +a bit+ beyond my skills, needs and understanding.. to be honest: I switched awhile ago to FinalCutExpress, and will use iM09 when I'll get a new rec-device.. hopefully this year (Santa! do you listen?!...)

IMovie full quality export problem...

Hello,
I filmed a widescreen video with a mini dv cam, which runs flawlessly smooth and clear as a bell at full screen in iMovie... but when I export it in either a full quality .dv, or the highest quality .mov and play them at nearly full screen in Quicktime, the playback is choppy.
How do I export a copy of my video that plays as smooth as it does in iMovie?
Thanks!

I am using the expert settings for quicktime export
If you want full quality, then you must use the Full Quality preset.
The expert settings don't export full quality even if you choose .dv output:

But that doesn't fully explain your original problem, though.

Full-quality export settings for use with Xbox 360

Greetings, all.
I use Rivet to stream video from my Mac to my Xbox 360. Recently I purchased a Sony HDR-HC5 HDV camera, and I want to see that video on my TV at full quality. I don't have an HDMI cable or a DVI-to-HDMI cable, so my only option is to stream this video to the 360 via Rivet.
To accomplish this, I have been trying to export my video at full quality from iMovie HD 6, but one of a couple things happens: 1- the resolution is intolerably low (I want 1080i), 2- the 360 complains about an unsupported format. I've tried exporting in QT format with expert settings, but no matter what I try, I have been unable to find a combination that produces 1080i that can be viewed on the 360.
Surely somebody else on here has gone through this exercise and has figured out what works. If you have any info on this, please share! I searched through the archives and didn't find anything useful. I've also searched on Google and the answer is still elusive.
Thanks!

Thanks for the reply, but the Xbox will in fact view MPEG-4, which iMovie can export. The only problem I'm having is with the quality of the output. The quality is in the movie that is exported, not in the Xbox's viewing of the movie - the movie looks just as bad on my Mac mini as it does thru my Xbox...
With experimentation, I think I'm getting closer to my goal...

Export to DV FULL QUALITY quality loss

I'm perplexed.
In the past, I have exported to DV without a hiccup, but now I'm having troubles. I need to encode some home videos to Mpeg-2 so I have to use another method than iMovie. I want to export to DV and then encode the video with ffmpegx, Mpeg Streamclip etc... but when I export the 16x9 video "full quality" it is NOT full quality. It looks horrible. When I export it, it looks very blocky - like it's a lower resolution. Of course, when I try to covert the file to another format (in this case mpg) it retains it's "uglyness..."
But the ODD thing is if I take the "poor quality" exported DV and re-import to an iMovie project, it displays properly from within iMovie.
Suggestions?
Tom

Thanks again for your replies. I am using iMovie 6. Here's a couple of snapshot to see what I'm talking about.
The first shot is a capture directly from the .mov reference file within the iMovie file package.
http://farm3.static.flickr.com/2332/1799517306181c3840eeo.png
You can see the girl's legs are a little blurry, but with the video running it looks fine.
The second shot is a capture from a full quality .DV export as viewed in VLC. Is that an interlacing issue? The ridges are viewable at all times as objects are in motion in the video
http://farm3.static.flickr.com/2230/17986776196cc455506do.png
Thanks for your comments about the high quality checkbox. It helps, but doesn't solve the issue.
Also, I double checked the frame rate and they are both all 29.97.

"full quality" movie is much fuzzier than compressed movie

Here's a strange one. When I export a clip as full quality and then play it back as a quicktime movie, the resolution is not nearly as sharp as when I export using "expert settings". The "full quality" file is, as I would expect, about 10 times larger than the compressed file, but much fuzzier.
What's going on here? Any help would be greatly appreciated!

But a friend suggested that I could do better by not compressing twice
Exporting as Full Quality DV doesn't involve any conversion, since DV is iMovie's native format.
But the strange thing is that On2Flix actually does a better job when you feed it a compressed file. I tried giving it a dv file to convert, and the result was poor.
Contrary to what many users beleive, DV is compressed. DV is 13GB per hour. Uncompressed video is (I think) over 50GB per hour. And that's for standard definition. HD is much larger.
So I checked their help section, which reads; "While Flix can encode uncompressed video files, it creates better looking SWF video files from video sources with some compression." I'm actually producing flv files, but I assume the principle is the same.
DV is indeed compressed, so I wonder why it doesn't work.
I have never heard of On2Flix before, so I have no idea why it doesn't like DV. Sorry.

How to export full quality in photos

In iPhoto you used to be able to export a modified picture in 'current' quality, which was full quality as shown in iPhoto.
Now in the new photos app this option is gone (only allowing to export original image in full quality). The best now seems to be exporting the jpeg at maximum quality which it's compressing the image from what is seen in photos app.
Does anyone know how to get around this...incredibly annoying as I want to edit images in photos, then export out that full quality to share or print or whatever.

You misunderstand what 'quality' means in this context. Quality is about the amount of compression applied to the image when the Jpeg is created. Is had very little to do with the quality of the photo. A well exposed image will print pretty much the same from a 1, 2 or 5mb image, especially from a domestic printer. You might see artefacts on a very high quality printer, but it's really not that mooch different.
Jpeg quality really comes into play if you use a lossless editor after exporting. This is in the nature of the Jpeg format. It's not an image format at all, it's a compression format attuned to images. Essentially its a special kind of zip file. When you open a Jpeg it's decompressed, so that 5mb Jpeg could contain a file that uses 50mb of RAM.
However, if you edit the image, then the file is recompressed and that means that some data is thrown away. In theory, edit a Jpeg enough times and you'll have an empty file. To overcome this, when you edit in apps like iPhoto/Photos the original file is not touched. The edit decisions are recorded in the db and only committed to the file when exported.
Exporting create a new file, containing the same photograph. But the quality of the file - which is the amount of compression applied - can be selected. If you found that the Preview in iPhoto always matched the reported size of the original then either a: that was a fluke or b: the image wasn't edited.
Medium gives about the same quality as the Preview, that's all.
The best quality to export at depends on the next use the file gets: if it's going to editing further, then high. Other than that it doesn't make a huge amount of difference.

Why is DVD fuzzy made via iMovie,Media browser, iDVD at professional quality. Original photos very sharp, DVD fuzzy.

I made an iMovie from very sharp photos, moved it to iDVD via Media Browser, Made "Professional Quality" DVD in iDVD. When I play the DVD back on eiher my iMac oxs 10.7.5 "DVDPlayer" or my DVD player hooked to my Sony TV set, the resulting movie from the DVD is unsharp, very fuzzy and very disappointing. I am using Memorex DVD-R discs. The playback colors of the made DVD are also changed from the original photos I used from i Photo.
Is this normal to loose so much sharpness and clarity in going from iPhoto to iMovie to iDVD?

Hi
OR the long long answer is something like this:
DVD quality
1. iDVD 08, 09 & 11 has three levels of qualities. (version 7.0.1, 7,0.4 & 7.1.1) and iDVD 6 has the two last ones
Professional Quality
(movies + menus up to 120 min.) - BEST (but not always for short movies e.g. up to 45 minutes in total)
Best Performances
(movies + menus less than 60 min.) - High quality on final DVD (Can be best for short movies)
High Quality (in iDVD08 or 09) / Best Quality (in iDVD6)
(movies + menus up to 120 min.) - slightly lower quality than above
Menu can take 15 minutes or even more - I use a very simple one with no audio or animation like ”Brushed Metal” in old Themes.
About double on DL DVDs.
2. Video from
FCE/P - Export out as full quality QuickTime.mov (not self-containing, no conversion)
iMovie x-6 - Don't use ”Share/Export to iDVD” = destructive even to movie project and especially so
when the movie includes photos and the Ken Burns effect NOT is used. Instead just drop or import the iMovie movie project icon (with a Star on it) into iDVD theme window.
iMovie’08 or 09 or 11 are not meant to go to iDVD.
They drop every second line in the picture.
Go via Media Browser (and then use MEDIUM - as HD does get a BAD Scale down quality) or rather use iMovie HD 6 from start.
3. I use Roxio Toast™ to make an as slow burn as possibly e.g. x4 or x1 (in iDVD’08 or 09 this can also be set)
This can also be done with Apple’s Disk Utilities application when burning from a DiskImage.
- iDVD - set Burn Speed in iDVD Pref. / Advance - BEST IS NOT BEST - x2 or max x4
- Roxio™ - set in burn process
- Disk Util tool - set in burn process
BEST IS NOT BEST
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). For SD-Video - if HD-material is used I guess that 4 to 5 times more would do.
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) - DVD-R play’s on more and older DVD-Players
7. Keep NTSC to NTSC - or - PAL to PAL when going from iMovie to iDVD
(I use JES_Deinterlacer to keep frame per sec. same from editing to the Video-DVD result.)
8. Don’t burn more than three DVDs 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-Player.
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 play-backed 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 play-backed 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 this to work I
Secure a minimum of 25Gb free space on Start-Up (Mac OS) hard disk
Use Verbatim DVD-R (absolutely no +/-RW)
Set down burn speed to x4 - less burn errors = plays on more devices
No other process running in background as - ScreenSaver, EnergySaver OR TIMEMACHINE etc
and I'm very careful on what kind of video-codecs, audio file format and photo file formats I use
and I consider the iDVD Bug - never go back to video-editor to change/up-date - if so Start a brand new iDVD project
Chapters set as they should - NO one at very beginning and no one in any transition or within 2 sec from it
Lay-out - Turn on TV-Safe area and keep everything buttons, titles etc WELL INSIDE not even touching it !
Try to break the process up into two stages
Save as a DiskImage (calculating part)
Burn from this .img file (burning stage)
To isolate where the problem starts.
Another thing is - Playing it onto a Blu-Ray Player. My PlayStation3 can play BD-disks but not all of my home made DVDs so to get this to work I
Secure a minimum of 25Gb free space on Start-Up (Mac OS) hard disk
Use Verbatim DVD-R (absolutely no +/-RW)

TO GET IT TO WORK SLIGHTLY FASTER
Minimum of 25Gb free space on Start-Up hard disk for SD-Video Quality and about 4 - 5 times more - if it is a HD-Project.
No other programs running in BackGround e.g. Energy-Saver
Don’t let HD spin down or be turned off (in Energy-Save)
Do not have more external devices connected as is of urgent need. Move hard disks that are not to be used to Trash - Or to be disconnected/turned off
Goto Spotlight and set the rest of them under Integrity (not to be scanned)
Set screen-saver to a folder without any photo
First - then make an active corner (up right for me) and set pointer to this
Secondly - turns on screen saver
Then - to show that it has nothing to show
No File Vault on - Important
NO - TimeMachine - during iMovie/iDVD work either ! IMPORTANT
Lot's of icons on DeskTop/Finder also slows down the Mac noticeably
if a project is in a real hurry
First - Then Start a new User-Account and
Then - log into this and iMovie get's faster too
And let Mac run on Mains - not just on battery

Share iMovie Full Quality lost option

I'm trying to share an iMovie project to iDVD and full quality is not an option. I chose share: Media Browser, Large. All my text is now blurry in iDVD and my photo quality is real fuzzy. How do I get the quality I have in iMovie into iDvd? I see no options. Help!

Another thing is that you must get your video into your project in a Loss Less format. IMove 8 defaults to an .mp4 which is a compressed format. I don't know how to set it to dv or a Loss Less format like in IMovie 6. I would hope there is a way, please post if you find out. Unless you Project is created with a Loss Less / dv format professional or not you DVD will be degraded.

Vertical Lines Appear Only in Full Quality DV File

I've had problems with vertical lines, detailed in another topic. This problem is different & very specific: My project has no vertical line problem, until I export it into a Full Quality DV file. The FQ DV file has vertical lines in the first photo of the clip when played in QT 6.5.2. I've deleted the DV file & re-exported 3 times, to no avail. Remember, the original project file has no problems.
It's not like I could do in the original project: Focus on the offending first clip. That first clip is now embedded into a DV clip with all the other clips. Do I just duplicate another DV clip & go thru the usual procedure to eliminate a clip with vertical lines? But, even if I delete the corrupted clip, I cannot replace it with a clean clip, due to the corrupting process that apparently occurs when I export my project to a DV clip.
Should I include a clean KB still at the beginning of my project before exporting it to FQ DV? If so, how do I delete that clip from the DV clip? It seems to me, once you convert to a DV clip, all bets are off re: editing individual components (clips) that make up the DV clip.
Any thoughts, anyone?

Since I started three topics re: vertical line problems & now that, with help from all of you & my own struggles, I've solved the problem(s), I feel I owe an explanation of where I am now.
I thought all the stills I made to extend the duration of the KB clips in my projects were themselves KB clips. Not so. I did not render these clips as KB clips. Therefore, using these clips as place holders had no effect in removing the vertical lines.
Thanks to all for their time, expertise, & patience.

After creating a new slideshow I export it with the setting HD 1080p it is then saved as a .mov i then create a dvd in idvd and the quality is not as good as the original photo's when viewed on the monitor or a TV, am i doing something wrong?

DVD's are only 640 x 480 (interlaced), so yes, the quality is not nearly as good. You should probably create your .mov in DV format to best match the DVD format

Widescreen DV, full quality export to .mov?

Hi,
I'm working on a short iMovie project in widescreen dv mode, and I'd like to export it in full quality to a .mov file rather than a .dv file. Is this possible?
Thanks!
Macbook Core 2 Duo Mac OS X (10.4.8)

What does s/he intend to do with the file?
Multiple codec conversions degrade quality (VOB->MP4->DV->?).
If you want minimal quality degradation, you should edit the VOB/MPEG2 file with MPEG Streamclip and convert that to the final codec. Or keep it as MPEG2.
The detour to iMovie loses some quality and you should have converted the VOB directly to DV -- the MP4 step was unneccessary.
iMovie's Full Quality IS .dv! You can make a DV-encoded .mov file, but what's the point? It would be just a wrapper for the same DV thing!
