Strange QuickTime conversion audio problem

QuickTime on my G5 will no longer export Final Cut files properly as H.264 - the video is perfect, but the audio just stops after about 1'30.
This never used to happen. I have tried with FCP container files and with FCP self-contained files, and the problem is the same. It started before the QuickTime upgrade, but even after upgrading, it is still happening.
Yet when I moved the exact same FCP file over to my MacBook Pro, and tried an export with the same settings as I used on the G5, it worked fine.
I can also do this export fine on the G5 with software such as MPEG Streamclip - just not QuickTime.
What on earth could be wrong that QuickTime's audio is failing at 1'30?

I confirmed that it's either a QT 7.2 issue, or OS 10.4.10 issue (guess which I think is more likely :-)).
I moved the iMovie to my wife's macbook, who thankfully usually hits cancel when the software update screen appears so it was still on 7.1.6 and OS 10.4.9. The movie exported fine. Not a great test, since I was changing processor types, iMovie versions, and OS versions, but it did work. Then I upgraded her to 7.2 and 10.4.10 (in retrospect, should have just done 7.2 to only change one thing, oh well), did the exact same export procedure, and the audio was corrupted the exact way that my computer broke it.
So it's in one of those components for sure. I opened a bug, #5345205, for what it's worth. Hopefully they'll be able to replicate somehow and issue a fix. too bad there's no easy way to rollback an update.

the results i get a odd. - the video exports fine, except for the beginning titles, instead a still frame image from somewhere else in the video occupies that intro, until the first transition- in this case- dip to white, then the rest of the video is fine. the portion of the beginning that does not show are composed of: livetype text credits in V2 - in which i have done a manual opacity fade up and down - so the livetype text fades in, over matte color solid in V1. in the exported video -i do not see any of this, all i see is a seemingly random still from somewhere else in the video. i can however hear the audio as it is supposed be.
cant figure out why this is happening. anybody know?
i think the livetype files are 1920 x 1080.
my FCP sequence is 720 p
this has only recently started happening and doesn't seem to be consistent.
im wondering if it has to do with the live type files, or the white solid?…
or the conversion settings above?

Earlybird is exporting H264 ... the Key Frames setting is determining the GOP length. This value should really be determined based on the complexity of the video, to my understanding, the actual frame rate has no bearing on it. If you have very complex fast moving content then a low Key Frame rate is advisable to ensure good image quality (although it will adversely affect the filesize) whereas if you have slow moving or static content (like an interview subject) then a higher Key Frame rate will still produce a good image but at a smaler filesize. The default of 24 should be pretty much fine as a catchall starting point.
Earlybird
Corrupted render files (and render references) can be a pain because FCP will use those files and references in place of the original media when building the export. And so it should as it does't want to waste time re-rendering sections that are apparently already rendered. Unfortuantely, as noted, if the render file has gone bad and/or starts referencing the wrong media then you'll get these wierd flashes of completely unexpeced and unwanted footage showing up where it shouldn't be. When you trash those files then QT / FCP will just go back and re-reference the original media ... so it's usually a worthwhile step to take just in case thats the problem. The worse case scenario is that it only that doesn't work and you spend some time unecessarily re-rendering.
As to why these files go bad? That I don't know. Why do Preferences get corrupted? That I don't know either but it definitely happens :-(

Quicktime conversion/audio sync problems!

I'm trying to export a project from Final Cut to a Quicktime file, but after its been converted, the audio is slightly in front of the video. Everythin is in sync in the Final Cut priject, so it must happen during the conversion. The original film source in HDV 1080p24. I'm just trying to turn it into a Quicktime file so I can put it on a website, but I need this audio to sync up properly with the video. How should I set this up?

ok, I output a lot of footage using quicktime conversion so I can edit in after effects or output for the web. I usually use the animation or h264 codec but the problem still persists regardless of which codec I use. < </div>
If the relationship between the tracks does not change over the length of the clip, that is, the audio doesn't drift more, your clip's tracks are actually in sync. One of the tracks, video or audio, has been set to start sooner or later than the other. I have no idea how that can happen, sorry, but I'm going to suggest the solution is going to be much less complicated than you might think: it's going to be a simple user error. We all have them.
It's a binary search, then, no way to shortcut it.
You try to find a good export and figure out what's different between a good one and a bad one.
Hope you get better advice on how to debug it.

Instead of Compressor went Quicktime conversion (still problems)

Hi,
Thanx for all the suggestions regarding compressor. I didn't even consider doing Quicktime conversion for my DVDSP2. I did this last night with a two pass knowing it would take along time. After about 9 hours with some 18 to go ( the piece is 78 minutes) I got two errors, one from my system and one from FCP. FCP simply said "Out of memory". And what I'm assuming was from my system with the yellow triangle and exclamation point. "Your startup disk is nearly full. You need to delete some files."
What I don't understand about these is that I had "video" as my destination. This is a drive within my firewire drive that I had earmarked for just video and it has 23GB of memory in it which should be enough for this piece. Am I wrong?
I know that the other internal drive that I have just for graphics such as video does have a lot on it. A 200GB drive, it only has about 5GB left of memory. Can anyone enlighten me or point me to some articles.
Thank you in advance,
John

Your system drive functions as a virtual memory device. When the software you are running requires more memory that the physical ram you have, the hard disk pages in and out of RAM as needed. Since your spec doesn't mention ram below, I don't know how much you have, but once it filled, overflow started to fill up your system drive. If that becomes full, the system itself could shut down.
You can think of the disk as a pantry and shelf space and RAM as the kitchen table and counter top. When you run out of space for food preparation, you can put stuff back in the pantry or put partially prepared recipes on shelves for later completion.
And please don't call disk space MEMORY - it is not memory. Memory is RAM. Disk space is storage. Also, I should mention that the efficiency of your hard drive drops off SIGNIFICANTLY once it gets over 90% full.
make sense?

Quicktime/Conversion sound problem

I've been trying to convert my mpeg video to mpeg-4. I've downloaded multiple conversion programs, and they work, except it doesn't transfer the sound. I don't know if it's the video I have, but the sound works fine when I watch it with Quicktime. I know this doesn't have anything directly to do with the iPod, but maybe someone could direct me as to where to go to find out what I can do? Thanks.

I think the sound and video are embedded together.
Quick time has a way of combining the two, but
conversion programs can't seem to separate them
and you end up with just Video. Your Quiktime player and
iTunes can tell them apart and they play them just fine.
What form were they in BEFORE you got them in MPEG?
I use a free conversion program called, strangely enough,
'Free iPod Video Converter'. It is made by Jodix and can
be found HERE.
Try it out and see if it does the trick.

Strange cd/dvd audio problem

Here goes. I have an M105-s3004. When I put a cd in the drive and play it, I get poping and crackling sounds mixed in with the music. If I play a dvd, the same.
Now, if I copy either the cd or dvd to my hard drive, and play from there, it plays fine. Also, if I shut the computer down and use the cd/dvd drive and the Toshiba Media Player (without booting the computer) both cd's and dvd's play fine.
So, the only time I have problems is when paying with the computer booted and playing directly from the drive. By the way, I have tried numerous player programs and they all do the same.
Anyone have any ideas??
Thanks
Mike

Audio and video out of sync when using quicktime conversion

hello,
i am editing a hdv project and want to export to quicktime. the client needs it in a specific size (700x394). they do not want the video in the file compressed, just the size of image. they are compressing the video through flash for the web. anyways, i used to just use quicktime conversion, custom size and use 700x394, but now when i do that the audio and video are sparadically out of sync in the product. the wierd thing is that the project plays fine in the timeline, but when i export the problem occours. i then, exported to a full res fcp movie and it is fine. then tired reexporting through qt pro to 700x394. when i did this their were no sync issues but the quality of the file was not so good, it look more pixely, certainly not as good as when i did it using quicktime conversion.
how can i export through fcp to get the 700x394 file? someone said 'use current settings' instead of using quicktime conversion? how do i do this? what do i need to do and what are my settings?
any help is appreciated. thanks a ton in advance.
cheers,
clay

What format are you converting the HDV to?
If it's animation, it is quite possible your computer can't pull the data rate. In this case it would be a processor / hard drive issue not an out of sync issue.

Strange audio problem

I've created hundreds of DVD's with my current set-up (iDVD 4.0 on a G5 with OS 10.3.9). Suddenly I encountered a very strange problem. The audio sounds fine in iMovie or when I play the .mov file. The volume seems fine--just like any project that I have done before. When I burn it to DVD, however, I can barely hear it with the volume on the TV all the way up. I have the Canopus ADVC-300, which allows me to export an iMovie project directly to a TV. When I do this, the audio is barely audible on the TV. Other DVD's and other iMovie projects play back with the correct volume. What in the world could be causing this? I'm totally at a loss on this one.

Thanks for the suggestion, but that's not it. I have been using the same version of Quicktime all along. I have had so many problems after upgrading software that I basically stopped installing upgrades. Also, I produced other DVD's after experiencing the problem with this particular project. It is so strange that the audio sounds fine on the computer but not when played to a TV (either through a DVD or the A-to-D converter).

Problems in Exporting in FCEx HD using Quicktime Conversion

I am currently editing video footage for web delivery using Final Cut Express HD and am having problems with the export using Quicktime conversion. When exporting to a Quicktime movie, there are no problems with the export. When exporting to MPEG-4 using Quicktime conversions, the audio is fine but the video image is very choppy and quality is significantly reduced. Is there a filter I need to apply to enhance the video for MPEG-4? Are there specific settings that work best with MPEG-4 in H.264?
Thanks for the help

MPEG-4 export only works in specific frame sizes. The greater the image size the higher the data rate you'll have to use to produce a good quality image. The quality of the compression is going to be to a substantial degree dependent on the quality of the original recording and the original compression.
YouTube uses Flash video for delivery BTW, not MPEG-4.

KNOWN PROBLEM BUT NO SOLVING: FCE CRASHES ON QUICKTIME CONVERSION EXPORT

Hi to all,
i'm an italian new user. I already use FCP on my Mac Pro 2007,and i purchased FCE for my new MacBook 2008 3GB Ram.
I use Snow Leopard for both machines. FCE is installed only on MacBook. The issue is:
When i put ANYTHING on timeline (effect,clips of ALL formatsetc) indipendently from Sequence presets,FINALCUT EXPRESS CRASHES IMMEDIATLY WHEN I TRY TO EXPORT TO "QUICKTIME CONVERSION". No messages,no report,nothing.
I searched and read many pages of this forum,i found a similar thread where the suggestions were the erase of preferences in Libray and reinstalling. I DID THAT but FCE crashes again.
I'd like to resolve the problem on this machine,because i will use FCE on this computer.
Follow, there is a sample video of my problem,i captured it for this thread. I hope will help you to understand exactly i want to repair:

Tom,
This is an excellent tip. I really learnt something I wasn't aware of. FCE always seemed to render anyway but it takes longer if you did not render first. But you are right. The manual mentions it as well.
Anyway, it does not explain really why, with Quicktime X installed, I and others experience FCE crashes. Before with Leopard , FCE really never crashed.
Contrary to what I mentioned, I still experience crashes, also after full rendering. Strangely enough, it does not happen all the time. It seems difficult to reproduce the circumstances when FCE crashes on export. Any suggestions?

Export Quicktime movie is not rendering video track, just the audio track. However, everything works when using Quicktime Conversion menu options. What is wrong with my setting for Export Quicktime movie?

Export>Quicktime movie is not rendering video track, just the audio track. However, everything works when using Quicktime Conversion menu options. What is wrong with my setting for Export>Quicktime movie?

When you converted the original files via MPEG Streamclip, what did you convert them to?
Have you tried trashing your preferences in FCP? Trashing FCP prefs is usually the first step when FCP is performing strangely.

QuickTime Pro audio sync problems

Hi, when I edit my videos in QuickTime Pro, the more I cut sections out from a video, the more the audio is out of sync from the video as it progresses; so at the start it is fine and in sync, but at the end the video and audio is not in sync at all. The video is fine before I start editing with no sync problems, it's only when i cut parts out. How can I get around this problem?
Thanks

ok, I output a lot of footage using quicktime conversion so I can edit in after effects or output for the web. I usually use the animation or h264 codec but the problem still persists regardless of which codec I use. < </div>

No Audio when I export using quicktime conversion

Hi,
This problem has just started. In my time line my movie places with both audio and video. When I try to export it using quicktime conversion I get a file with video but no audio. If I go to the audio settings button and click preview, I hear nothing. I have exported using the exact same settings many times before without problems.
If I export the file using quicktime movie, I get both audio and video.
This is driving me crazy, Can anyone help? Thanks!

I got no audio on the DVD when I exported from FCE using the Quicktime Movie setting. I finally determined it was because my audio was at 44.1k Hz. I upsampled to 48k and there was sound on the final DVD. This is not normally a problem when input comes from a camera, but if you are doing a DVD of a Keynote presentation and adding separate sound to it from a CD, this becomes a problem.
Certainly no more than a little annoying that there's nothing said during the FCE export that this audio won't be exported. It's just not there.

Aspect ratio problem with Quicktime Conversion from FCE HD 3.5

I have a FCE 3.5 HDV project (16:9 aspect ratio) which I am trying to export using Quicktime Conversion for eventual web-streaming. I have tried various settings including "maintain aspect ratio" and the "letterbox" options. After every multi-hour attempt, the end result is just what I need, except the aspect ratio is always 4:3 and vertically squeezed.
What settings should I use for a small to medium sized version of my movie for streaming on a website, but in the correct aspect ratio? I'd prefer a 16:9 Quicktime frame, or at least a 4:3 Quicktime frame with black bars.

I too have been having some problems, same software. Export to iPod completely ignores the intended aspect ratio and is non-adjustable and squeezes the footage. It looks fine on the canvas but gets messed up on export. A 4:3 video that should be 640x480 ends up being 640x426, and a 16:9 video that should be 640x360 looks to be getting 640x426 as well.
Currently, my work-around is to export to DV file, then export to iPod. Being a double encoding, it is quite wasteful in terms of time and processing power. Is there something else I can do?

Weird audio problems with Motion when exporting quicktime videos

I have a Motion project with 2 video clips of people talking. When I create a RAM preview everything plays back fine. When I export a quicktime, the first second or so of each video clip (within the quicktime) have no audio. I've adjusted the in and out of each clip in Motion but I don't think that would make the audio disappear on export. Thinking it was just a bad export, I tried just exporting the audio and the same thing happens.
Here's what i'm using:
Mac Pro dual 3.0 Xeon
10 gigs of RAM
Motion 2.1.2

hi,
motion 2 had some odd audio problems that surfaced now and then. The only way round it was to bring the clip into FCP and edit the audio in there, and then export from fcp.
Motion 3 might have fixed this. Not sure havent had the problem for some time, since I make sure all finnishing is done in FCP.
hope this helps
