Quicktime video quality

I'm trying to export my fla to a video format supported by
iDVD. I was able to export to a quicktime movie .(mov) but the
quality was horrible even though i chose the highest quality
settings and used high res images in the fla. Are there settings
that i missed? is there a better video format that i should be
using? Image quality is very important for this project.
I'm still new to flash so any help would be great!

Hi,
What setting you used? you have to set the QT export setting
to the hightst you can get, but firts you have to make sure that
the sources you sue in Flash is high quality, otherwise, you can
not output better quality than the one you input.
You can also export your Flash as image sequance and gether
it in a other product like After Effects.
Hope this helps.

Quicktime 7.4.5 HD Video Quality is Poor

Hello, every since I updated to the latest QT version the video playback quality of my HD's movies has been poor. For example when I play a 480p trailer the video appears very jaggy around the outlines of text and objects. The QT preferences are set to High Quality.
I tried completely reinstalling QT and still got the same results. Luckily I did still have the previous QT version so I installed that and now the playback quality is perfect once again. Guess I'll have to stick to this version until another update comes out.
Any one else have this problem?

I just tried using that option in the 7.4.1 version that i installed and doing so actually reduces video quality, don't think that would help in 7.4.5. Funny thing is when i do put it in safe mode the video quality looks exactly the same as in 7.4.5.
It's almost as if the newest version is running in safe mode even though i have it set to directx, strange...

Comparing video quality of AVCHD BluRay discs using Final Cut Pro Share vs Compressor

Up front, I will admit to being a newbie when it comes to using Final Cut Studio 3 and would appreciate some feedback from the Apple forum experts.
I have spent a lot of time trying to determine how to achieve an optimum group of Compressor 3.5.2 settings so that the playback video quality of an AVCHD BluRay disc is equal to or better than one created by using the simpler auto settings of FCPro Share, version 7.0.2.
When using Compressor’s auto/default maximum settings, I experienced the same error message reported in:
Error MessageDuring Creation of Blu-ray Disc in FCP and Compressor 3.5
https://discussions.apple.com/message/12073794#12073794
I have since made some Compressor AVCHD Discs with smaller bit rate settings and compared video quality with a single FCP Share AVCHD disc. Both seem to be equal in providing a very good video when viewed on my new Panasonic DMP BDT 310 BluRay player. However, the Compressor AVCHD discs show some motion artifacts not present with the FCPro Share version, especially when scrolling text or when objects are moving through the field of view, and visible artifacts are seen from a stationary chain link fence and other lattice work in the background of the video sample.
My sample video used for the comparisons between Compressor and FCP Share discs is a 21 minute duration home movie, originally captured from a mini DV, Canon HV30 1080i camcorder using ProRes HQ encoding(1440x1080), and dragged into FC Pro 7.0.2 timeline where 10 chapter markers have been inserted.
To create an AVCHD disc using FCPro Share, Markers are used to set the IN and OUT points, Select IN to OUT from the timeline, pull down File Menu Share, Select Create BluRay from options in pop out Share pane, and designate output device along with picture files for Background, Logo, and Title options. When these are completed, click on Export. My 21-minute video required almost two hours for encoding including about 10 minutes for burning. This accomplished on an iMac 3.06 GHz Intel Core 2 Duo.
To prepare this same 21-minute video for use with Compressor, I again Select IN to Out from the FCPro timeline, but this time use File Export as a QuickTime Self Contained movie including Chapter markers. Then Open Compressor, choose Create BluRay from Template pane, right click on the down arrow in the Batch window and load the QT self contained movie file. From there I went to the Inspector window and tried various combinations of bit rate settings along with Frame Encoder options such as Better or Best motion parameter controls.
I have tried the following combinations of Bit rate settings along with varying Frame Encoder controls and burned an AVCHD disc for each example:
Example A
Compressor set to 6 Mbps Average and 8Mbps Maximum, Frame Encoder settings OFF. Approximately 4 hours to encode although the time remaining estimator indicated a larger value of ~7 hours; not an accurate estimator at all.
Example B
Compressor set to 6 Mbps Average and 8Mbps Maximum, Frame Encoder settings ON, using “Better (Linear Filter) and Better (Motionadaptive)” settings. Approximately 4 hours to encode, not the 13 hours that were estimated.
Conclusion: Comparing A & B Compressor versions, Disc B showed some improvements in reducing motion artifacts over Disc A.
Example C
Compressor set to 13 Mbps Average and 15 Mbps Maximum, Frame Encoder settings ON, using “Better (Linear Filter) and Better (Motion adaptive)” settings. Multipass checked. DeInterlace was checked. Unknown hours to encode; about 8 hours done overnight..
Conclusion: Disc C showed some minor improvements reducing motion artifacts over Disc B
Example D
Compressor Auto settings,i.e., 15 Mbps Average and 17 Mbps Maximum, Frame Encoder settings ON, using “Better (Linear Filter) and Better (Motion adaptive)” settings. Multipass checked. Approximately 12 hours to encode, done overnight. Inserted disc next morning after the overnight encoding was completed, and a few minutes later an error message pane appeared that the maximum bit rate had been exceeded. This message was consistent with the Apple posted thread referenced above. Unfortunately the long overnight encoding was wasted.
It seemed to me that the best Compressor settings for suppressing the motion artifacts were displayed by the disc burned in Example C, i.e., 13/15 Ave/Max Mbps with“Better” Motion settings in the Frame Encoder.
However, when this disc was compared to the AVCHD Disc burned using the FCPro Share, the latter still seemed much better. I do not know what the auto bit rate values are as set in FC Pro, but for me, the quality is quite good AND the motion artifacts are significantly reduced, especially evident with the scrolling text.
Sorry about this long post, but I thought the detail would be necessary for the experts, and maybe helpful to others trying to get started in this BluRay arena. Did I misuse Compressor? I think the sample video exported as a self contained QT movie was the right thing to do? Not sure where I went wrong.
Thanks in advance for Feedback and Recommendations. For now, I’m going to stay with the simpler process using Final Cut Pro Share function.
BoBo

Thank You, Brad, for responding; glad to hear I'm not the only one having similar Compressor issues.
You may have hit on something. Perhaps Compressor's use of H.264 encoding was the reason for my motion artifacts? And perhaps Final Cut Pro Share retains the 1440x1080 quality as it burns the AVCHD BluRay disc?
I had Toast 10 for less than 30 days a couple of years ago, and was lucky to get a refund.
What version of Toast do you have? Wondering if new Toast 11 has improved previous bugs, especially upgrading its Chapter text, pictures, music. I would go back to Toast if it came close to mirroring DVD Studio Pro, or even iDVD capabilities.
Thanks,
BoBo

MacMini - LG 32" (32LB75) Problem - Poor video quality and now no picture.

Hi there, apologies for the length of this post....
I purchased a mac mini 1.8Ghz with 2Gb RAM yesterday with a wireless keyboard and mouse and hooked it up to my 32" LG 32LB75 using VGA. On startup the display looked ok, I managed to click through the various Leopard initialisations. I bought the machine for use as a front room media player for mainly DivX movies and the occasional bit of music.
Once I had installed the DivX codec I opened a DivX file in Quicktime and selected "full screen mode." As soon as the movie started I became quite disappointed. The picture quality was quite pixelated ("noisy") and certainly not as good as when I play the same movie file from my old dell PC on the same LG tv (the dell PC has a 64Mb PCI radeon 7000 which connects to the tv using the same VGA port as the mac).
Anyway just to give the mac a fair go I thought I would try out some genuine quicktime video samples from the itunes store (this time viewed from front row)....again not brilliant.
So I thought I would investigate the screen resolution to see if I could improve things. It appeared the resolution was set to 1900 by 1200ish I say "ish" because I can't remember exactly. I then attempted to reduce the resolution and eventually I settled on one that looked quite clear with the font size big enough to be easily read. Again I tried the movie and there wasn't much (if any improvement). Whilst changing resolutions the screen would go blank for a few seconds but on one particular setting (can't remember exact numbers) the display went blank and never came back. The tv now just displays "no signal".
I despaired and connected the mac to a 17" Iiyama montior that I use with a PC and it worked ok. However each time I tried to "hot swap" back to the television I would end up with no picture.
I'm really disappointed because everything else about the mac I really like. Particularly the remote for frontrow which is precisely what I wanted it for. The problem is I've spent over £500 and now seem to have a lesser quality picture than I had to begin with (ignoring for the moment that I don't have any picture!!)
Anyway my questions are these, answers to any or all most appreciated.
1) what is the easiest way to get my mini to start displaying on my tv again?
2) what would the optimum resolution be? My television mentions 1366 x 768 in the manual
3) If the mini doesn't offer this resolution in the pick list is it advisable to "force it" using some alternative software (ie 3dexpress.de)?
4) Is the video quality affected by the software player? ie would VLC give better picture with DivX over quicktime/itunes/front row?
5) How likely is it that the video resolution of my new mac mini isn't "as good" as my old dell machine with its PCI graphics card?
6) Finally if I don't get results as good as my existing PC setup, how accomodating are apple with refunds? I bought it from a UK high-street apple store. The back of the receipt mentions a "14 day not satisfied" return policy but then goes on to say something about being "unopened"...which seems a little confusing. Ie how do you know if you're satisfied until you've actually used it?

Hi there
the solution was to remove the various display config files in leopard and then restart the machine, this got my display back on the tv (albeit off centre). To fix the "off centre issue" I used the LG "auto correct" feature from the remote control "menu > screen" options.
The apple support site describes how to remove the affected leopard display files here http://support.apple.com/kb/TS2213?viewlocale=en_US As you will see their resolution consists of 2 main steps, the first one involves starting your machine in safe mode, if this doesn't work then you proceed to the second step where you remove the files using a terminal prompt.
I didn't bother with the first step mainly because I don't think I can start my mac in safe mode since my only keyboard is wireless (bluetooth). So I connected the mac mini to a 17" LCD monitor (which thankfully did display the video signal ok) and removed all the listed files using terminal. I then shut the mac down, swapped the VGA cable back to the LCD tv restarted the mac and it detected the tv and set a resolution that worked. I then very carefully reduced the resolution down to one that was recommended by my tv (1300ish.. x 768ish??).
At this point I was back to having an acceptable signal but still a little off centre. So I used the TV remote, pressed menu, went into screen options and chose "auto correct". Picture then filled the screen perfectly.
The problem seems to be, leopard lists a bunch of resolutions that it believes your tv/display can handle but it would appear that in fact some of these resolutions are not supported by your TV and if you choose one of these your signal disappears and you can't get it back.
I would still say that I'm not 100% convinced with the mac mini's onboard graphics (I have a 1.8GHz version). I'm going to download some HD content and see if that improves things, but certainly my existing DivX collection looked a little sharper and clearer and better coloured using my old dell PC with its radeon PCI card. But the difference in picture quality is outweighed by the convenience of its size and the font row interface. I might tinker with putting Windows Media Center on it one day, perhaps that might improve things.

FCP Novice needs help with video quality and FCP 5!!

Hi,
I have a real problme that I cannot seem to fix. I think its because I am doing something really wrong!
I have a Sony HC42E MiniDV Camcorder which by default records video in full widescreen. I recorded several tapes this way and have now begun trying to edit them in FCP 5.04 (Tiger 10.4.6). Whenever I log and capture my clips they appear to be fuzzzy and unclear on the Mac monitor whilst being totally crisp and sharp on the camcorder viewfinder. I tried capturing using the DV PAL 48Khz Anamorphic Preset which keeps everything the right size (the final output needs to be true widescreen and not with black bars added) but the resulting video on screen is blurry and bitty. I then tried capturing using the DV PAL 720 x 576 normal preset and the video is a little clearer on the screen (for both presets I have chosen lower field dominance) but when I play back it plays back in widescreen on the mac canvas window but at 4:3 on the camera's viewfinder.
I then assumed that maybe this is just becuase the mac screen (CRT by the way) doesn't use fields. So I exported the sequence as a QT movie using DV PAL 16:9 and used quicktime (OS9 Classic - my compressor has never worked because of the dreaded "unable to connect to baackground process" problem which I've never managed to correct) to convert it to MPEG2. When I import this as an asset into DVD Studio pro 4 and set the track size to 16:9 it comes through at the right aspect ratio. However it looks blurry on screen. Thinking that this will be fine on a TV I burned the disc - inserted it into my DVD player (a good one!) and watched it on my new 32" widescreen TV (a good one!) and the picture qualitty is poor. Its so much blurrier and bittier than the original footage looks when played through the camcorder's viewfinder!
The final footaage looks like an old VHS recording that's a year or two old!
Does anyone know how I can capture my footage in FCP with the maximum quality, edit it without quality loss and the export it for DVD again without such significant quality loss whilst all the time keeping it at proper 16:9 widescreen?
Is there some presets I should be working to?
I'm tearing my hair out! Help!

Hi Guys,
thanx for your replies.
here's the latest:
Brian, I followed your instructions and the DVD burned successfully. However the video quality of the dvd when viewed on my TV ('ve tried on all 3 of my tvs now) is still a lot poorer than the quicktime movie that was imported into DVDSP4. When I play the original QT Movie on my Mac CRT monitor it looks a little blurry and grainy because I guess its non interlaced however when viewed on an external Video monitor it looks great - very sharp.
When I view the burned DVD on my television the picture quality looks like the non interlaced version of the original QT Movie that appeared on my Mac CRT and not the sharp interlaced (lower field) version that appeared on my external video monitor.
Its almost like taking a sharp jpeg into Photoshop and applying a gaussian blur of about 0.3 followed by jepg compression compressing it down to 5% quality!
I'm totally mystified. Can the conversion to Mpeg2 be removing all interlacing so that you get the less sharp computer monitor look? I just want the video on my final DVDs to be as good as the original source footage! I appreciate that along the way there might be loss of some quality but surely not that much?
Does this make sense to you guys or am I still doing something very wrong?
Robert: I have tried setting all manner of drives including a fresh external firewire HD with nothing on it (clean out of the box) but it doesn't seem to help.
Brian: I tried the no network suggestion a few months back but I'm not sure if I got it right. At the moment I have broadband through an external speedtouch usb modem and am also connected (occasionally although not for the last 3 months) via a crossover cable to my PCs ethernet card. When I last tried the No Network solution I had immense trouble getting my internet to work again! Can you please help me by directing me to the best ay to do this while protecting my internet settings?
any more help guys would be greatfully appreciated.

How should I best import HD Videos from the new iPad to my mac without loosing video quality?

The new HD video on the new iPad is awesome, but it can eat up a lot of memory in no time. I would like to know what is the most recommended way to export my ipad movies to iLife on my mac without loosing image quality, so i can free up space on my iPad.
If I use iPhoto I notice that the file size of the video from the new iPad is a lot smaller then if I use iMovie to import the same video.
Example: I import a 53 second video from the new iPad to iPhoto and the imported file has a file size of 143 MB in iPhoto. (iphoto save the video as IMG_0048.mov)
I import the same video to iMovie manually and the imported file size is 843 MB in iMovie. BIG DIFFERENCE. (iMovie saves that same video as clip-2012-03-20 16;13;08.mov)
Now to really be confusing: I go to Image Capture program and locate the file manually on my iPad and is has the same name and file size is what is in iPhoto.
So either iMovie is making the File a lot larger when it imports to an event, or the file I'm looking at is actually the iPhoto version that I get because I sync with iPhoto.
The second issue that I have is that now I have 2 videos on my hard drive: one in iPhoto, and one in iMovie for a combined data storage of close to 1 GB.
I would like to be able to import ALL my iPad recording into iPhoto and then delete the video from the device when done.
But if I loose video quality, I'm not happy about that. Secondly, by importing video from my iPad into multiple iLife programs, I'm creating duplicates with sometimes different quality. Any suggestions? is there a setting in iPhoto that can do all this for me?
Robert

Don't use iphoto to deal with movies. it's not really meant for that. use Quicktime or iMovie to work with your videos

What can I do to improve a blurry quicktime video that was SMS'd to me it is a 1.24MB .mov file and I have QuicktimePro. It was taken on an Iphone but I am not sure with what software.

What can I do to improve a blurry Quicktime video that was SMS' texted to me? I think it was taken on an Iphone and it was sent to me as a 1.24MB .mov file and I have Quicktime Pro if that helps. I REALLY need to make this as clear as possible, the audio is good, video is blurry. Here is some additional data:

anything I can even try? Sender is off the grid? I don't need a production ready copy just viewable?
You can rescale (stretch) the size of the display but this will only make it blurier and/or introduce pixellation. When the file was encoded at a lower resolution much of the original data was thrown away to make the file smaller. This data is gone/missing and cannot be recreated from what is left. What you've got is all you have to work with. Any filters you can apply will require re-compressing the file again which will likely introduce more artifacts and increase the size of the file without really improving its overasll quality.

Why is playback video quality not as good as the source?

Hi. I'm not new to PrE but am new to the forum.
I've been using PrE 2 for about 7 years. I got a newer computer running Windows 7 and basically was forced to upgrade to PrE 12 because PrE 2 didn't run very well on the newer machine. Once I installed PrE 12, I was eager to jump into my first project on this machine.
I expected that with a newer machine and the latest software, I would get outstanding results--hopefully much better than what I always got with PrE 2 on the old machine. With PrE 2, it was not uncommon that the imported video seemed lossy on playback or for whatever other reason seemed not as good as the source video.
Unfortunately, the results on the new/new were no better than the old/old. So I switched to my wife's (even newer) machine running Windows 8 and got the same results. Then I thought that perhaps the output to DVD would be better than what I saw in the PrE editor. No dice.
The video quality of the source isn't the greatest (see below), but I expected that the PrE 12 would be no worse.
What went wrong?
Here's what i'm working with on the current project:
Machine 1:
HP EliteBook 8560w
Intel Core i7-2640M 2.8 GHz CPU
Window 7 Enterprise SP1
2 GB RAM
360 GB available HD space
Machine 2:
Dell Inspiron 3521
Intel Pentium 2117U 1.8 GHz CPU
Windows 8 Touchscreen
4 GB RAM
400+ GB available HD space
Video Source:
iPhone 4 video (MOV format)
Thanks for ANY help you can give me.
BTW, I noticed that Steve Grisetti is one of the frequent commenters on this forum. In case you're reading this, Steve, I want to thank you and Chuck E. for your PrE books. I purchased one several years ago and found it extremely helpful. And surprisingly, I found that with PrE 12 I could still use the book that I purchased before because most of it was still relevant to the new software. Still a great purchase!!

Please excuse if I mention things you may already be aware of, but I did not want to take anything for granted.
The installed RAM on Machine 1 is too low for HD work, and I wonder about the processor on Machine 2 even though it has more installed RAM than that on Machine 1. For now, I will bypass the usual drills and get to the source media and project settings.
1. From what I can put together, your source media from iPhone 4 are 720p up to 30 frames per second. That usually translates into a variable frame rate which can be problematic for Premiere Elements. The variable can lead to audio out of sync, but not necessarily. If all else fails, then it is onto HandBrake or the like to change the variable into a constant frame rate.
2. One of the features of version 11 and 12 is the program taking over the setting of the project setting based on the properties of the first video drag to the Timeline. Some times it does it OK, sometimes not. When not, then you set the project preset manually yourself based on what you know to be the properties of your source media. Please refer to the following which includes how to set the project preset manually.
http://www.atr935.blogspot.com/2013/04/pe11-accuracy-of-automatic-project.html
Based on what I have read about the properties of the iPhone 4 video, I would suggest the project preset (assuming a NTSC set up)
NTSC
AVCHD
AVCHD-LITE 720p30
One of the important things to remember is that Premiere Elements 11 and 12 have as their default project preset
NTSC
AVCHD
Full HD1080i30
and not the NTSC DV Standard of versions earlier than 11.
When 11 and 12 do not get the automatic project preset correct, they do not give you the closest fit, rather they give you their
default NTSC AVCHD Full HD1080i30 which is not going to be appropriate for 720p video.
Classically it is written if you have the correct project preset you should have no colored line over the content when you bring the video to
the Timeline manually set. But, just the variable frame rate can trigger the unrendered indicator (orange instead of red in versions 11 and 12).
So, rendering the Timeline would be indicated to get the best possible preview under these circumstances.
Do you have the latest version of QuickTime installed on either of your computers?
More later.

Video quality of burned DVD way inferior to content viewed in iDVD program

I notice the video and menu quality on my burned DVD is VASTLY inferior to video and menu quality when viewing menus and content in the iDVD program while building the presentation.
Having encoded at "Professional Quality" to a single layer DVD which didn't look so good, a number of posts in this forum suggested that "Best Performance" actually renders the best video quality.
I'm using high-quality media from Verbatim so that's not a problem. The DVD's burn fine.
The content -- all high-quality QT movies with great resolution, color and crisp text and animation, look great in and of themselves, and when viewed in the iDVD program. The menus and clips embedded in the scene select buttons, all look crisp and clean.
Burned to DVD however, the video looks noticeably "worn" and the clips in the buttons lack any kind of crispness or resolution. Definitely disappointing. The animations look herky-jerky.
Anyone know what the problem is?

Hi
No iDVD has a fixed quality - as old time TVs
• PAL 625 lines (720x576)
• NTSC 520 lines (720x480)
so Your Mac screen are way higher resolution.
There are NO HD version of iDVD - yet
*DVD bad quality*
copy of an answer on a similar question - may be of help
the iMovie 08 & 09 don't apply
There are two problems in this question.
• iDVD
• iMovie'08 or 09
iDVD - can only handle Standard definition TV quality - NO version can handle HD !
SD-TV
EU - PAL system = 625 lines analog display (no pixles) 25fps
US - NTSC system = 520 lines and 29.97 fps
That's the best iDVD can do.
iMovie up to version HD 6 - could handle interlaced video (displaying every second line
first then start over with the rest - 25fps = 50 frames of interlaced video
less flickering.
iMovie'08 and 09 has destroyed this by deleting every second line
Result a resolution of
PAL 312 lines
NTSC 260 lines
So photos displayed this way will look crappy.
Improvment
Use iMovie HD 6 or FinalCut Express or Pro
Else only way I know of to get "full" quality is by using other tools all together.
Roxio Toast™ 10 Pro (incl BR-component) and here the included FotoMagico™ for SlideShows.
Toast™ also can burn Blue-Ray - even on standard DVD (but much less eg 20 min movie)
These BR-DVDs Can only be playbacked on a Blue-Ray Player (eg PlayStation 3)
But they look super.
A more specific part reg. FinalCut
I do in FC-Express or Pro
• Export out as a QuickTime .mov file
• Not selfcontained (not important but saves time and spaces)
• NO QUICKTIME CONVERSION (Important)
I use
• Verbatim DVD-R disks
• Burn at a reduced speed x1 or x4 recommended by many)
• Secure a minimum of 25Gb free space on internal boot hard disk for 4x3 SD video
and my guess is that I would secure 5 - 6 times more for 16x9 HD
(Still no version of iDVD can do HD)

I chat 4 video quality is terrible!

Can someone please help!I just switched over from a pc to macbook mac ox 10.5.1 expecting great video quality with i chat or skype but instead had to deal with error 8 messages in i chat after all the headaches of opening ports in my router, the audio video is working but the video quality is very bad my own preview is clear and my boyfriend sees me clear,but the image I get of him is very pixellated. I've set the bandwidth to none and speed to 1.5 in quicktime, my average speedtest results are 6500 downloads and 400 uploads. connection doctor average is usually about 350-400 framerate 9 -10 for both local and his connection. We both using have tried connecting directly to the modem, however I still get poor image. He is also using a mac ox 10.5.1 i chat 4 same machine except for different graphic card I have a gma x3100 144 mb while he has the gma 940 4mb can this have something to do with it ?

Who is your ISP ?
If Comcast, Road Runner or Verizon FiOS then set the Bandwidth to 500

Poor video quality, pixelation, flickering on moving subjects in frame

I made a quicktime movie using File>Export>Quicktime Conversion... in FCP using H.264 compression codec with best video quality and 16-bit audio. video was originally captured in miniDV. Self contianed movie was made and looked pretty good in Quicktime, though the edges of moving subjects in frame did have small wavy lines (I assume from interpolation of DV?). Anyway it was acceptable to me (but if there is a fix please advise as I figured this was endemic to miniDV itself.)
Then I created a DVD in iDVD 6.0.3 with several slide shows and two relatively short movies (12-14 minutes in length each). The edges of moving subjects in frame (i.e. persons walking into the frame) now have large square pixelations sort of like this --->( |-|_|-|). At anyrate, the fine wavy lines from the QT movie have become much worse when there is movement, and I'm not talking speed, just any movement like a hand moving in the frame, etc. Otherwise the quality of the video is comparible to the exported movie from FCP.
Does anyone have suggestions for how to eliminate this problem?
thanks!

That's normal interlacing. You usually want to preserve those comb lines if your target is TV display which will hide them and use them to make smoother motion.
http://www.sjoki.uta.fi/~shmhav/SVCDon_aMacintosh.html#interlacing
But if your target is a computer display, then you usually want to deinterlace them off because they look ugly on a PC monitor.
originally captured in miniDV ... H.264 ... Then I created a DVD in iDVD 6.0.3
No! You should not convert the original DV to H.264 if your final target is a video-DVD!
Just keep it as DV. And take care that your FCP export to DV is bottom field first field dominance because otherwise you get terrible zigzag movement artifacts! ...I don't have FCP so I can't give you more advice on that (mini-DV ->iMovie ->iDVD handle all this automatically).

Quicktime Video Output Components equivalent in QTKit?

I need to output video frames to external devices such as Firewire cameras and Digital Cinema Desktop. This used to be handled with Quicktime Video Output Components, but I'm not seeing an equivalent with QTKit. My application is 64-bit, so I cannot use Quicktime directly. Is this available in QTKit or another 64-bit compatible framework?

Benjamin: The Digital Cinema Desktop is a Final Cut feature, even if implemented as a Quicktime Video out component. As you can see (by the lack of options) is not really meant to be invoked from other applications which use standard Quicktime video out for external previews. That requires a device with a proper QT video out driver. You could use an inexpensive device, like a Blackmagic Intensity with an HDMI to DVI cable, to feed the second display.
Or you could just ask AE to play RAM previews at full screen, in which case you don't need to enable video previews at all. Together with the ability to take into account a calibrated display's profile, this should make for very high quality previewing on computer monitors.

Video Quality in imovie

I am capturing video using a Sony HDR-SR12 Handycam, converting the video using QT in a MPEG4 format, so can use the file with imovie. Once I transfer over to imovie the video quality is very bad. Playing the video out of the camera on to the TV the picture is perfect, also the video seems fine in the Microsoft Picture Browser.
Is this an imovie issue or a conversion issue? Any suggestions would be greatly appreciated.

Hi John
Sorry i don't have the answer, but i'm interested in your question because i have the same kind of issue when i import in iMovie 08, 09 and iMovie HD from my Sony SR10 AVCDH camera.
I just can say that when i export directly from iMovie to iDVD the quality is bad; this seems to be a well known problem and it is recommended to export video using the Quicktime with H264. With that method, i can obtain good quality in the STATIC images, but during the panoramic movements of the camera the final result (i mean a DVD on my cathodic TV) is disappointing, with a "jerky" rendering.
You can download on my iDisk an exemple of it at: http://public.me.com/leclercqpascal
When i compare with the same sequence treated on the PC Sony's software, i find in the latter case a perfectly smooth result.
The problem is the same when i import from the camera to FCE.
Help welcome, because i would be disappointed to resort to a PC software!

Multi-Person iChat Video Quality

Hi,
I am using iChat with 2 other person (so a total of 3 people in the video conferencing). What we noticed is that the audio quality remains great. But as soon as the third person joins the video chat, the video quality decrease dramatically.
Any one experience this problem?
Thanks.

Thanks for the reply.
Have you set the Quicktime setting, goto sys
prefs/quicktime/streaming/streaming speed set what
you get from your ISP go no higher then 1.5mbps(dont
use automatic)
I didn't know that Quicktime has anything to do with iChat. I will check that tonight.
In ichats prefs click on video and change bandwidth
limit to NONE.
Alread set to NONE so this shouldn't be a problem.
Also all of you do a speed test
http://www.speedtest.net/ and tell us the up and
download speeds are.
I have done many similar tests and it is consistently rated as "excellent". I will need to do the test to find out the exact rate tonight when I am home.
So, out of the 3 things, sound like the Quicktime setting is the only one that I have not done.
Thanks.

IChat video quality better with .Mac subscriber than with AIM?

The quality of my video chats with one brother who also has a .Mac account is noticeably better than my chats with another brother, who uses iChat with an AIM account. I'm in the US, they are both in UK. All of us have almost identical iMacs. The one with the AIM account supposedly has a faster Internet connection. My question: is the video quality of iChat better if both users have .Mac accounts than if one has an AIM account?

The Screen names make no difference.
It is about a combination of Proccessor, Video card in iChat 4, internet Connection and settings and the amount of Bandwidth you get out of that connection.
As Defcom (UK) has said start with those basic Settings.
In iChat 3 and 2 the Quicktime setting when on Automatic is read as a 0 (zero) and this effectively Caps iChat.
In iChat 4 the Automatic setting is seen as 384k which is the MINIMUM for a 4 way chat.
As far as an Internet Connection goes this should be at Least 100k in both Up and Downloads.
Due to some data stream management to cut down on Peer-to-Peer file Sharing it pays to limit iChat in the Video Section Bandwidth Limit section to slip under the Radar as it were. There are two main ISP doing this Comcast and Road Runner in the States.
Verizon offer a FioS fibre service that is not that stable in speeds and jumps all over the place which is then too fast for iChat to keep up and that should use the cap in iChat Preferences as well.
