Out of Sync/Export Settings/24p

I'll try to explain this the best way possible....
I have a bunch of project files for a movie that i'm working on. I felt it was easier to edit in a bunch of different projects, and then combine them into one solo project at the end. However, once I lay all the edited video+audio from the project files into one final project, the audio goes out of sync. Even when I export it, the audio is still out of sync.
I am combining 24p and 60i files, my sequence settings are for 24p, and I was planning on exporting to m2v for DVD Studio Pro.
What would be my best option for exporting for DVD without an audio sync problem or the "streaking" effect (three frames forward, one backwards) that plagues 24p exporting.
Thanks in advance,
Natha

I don't want to sound impatient, but this is for a college project that is due in 48 hours... can anyone help ASAP?

Out of sync exports

Hi,
we have this recurrent but intermitent problem:
When exporting (sharing) in Master File mode, Apple ProRes 422 with Roles as Multitrack (8 mono tracks), some of our projects are out of sync by a frame.
This we can see with a one frame 1khz beep set at 9:59:57:00 in the leader we use. On the export the beep ends up one frame early and the the whole export is out by a frame.
Most of our material is mxf wrapped xdcam hd or sd edited directly in fcpx using Hamburg Pro Media mxf plugin.
But the out of sync exports happen with other material too.
The problem is not constant as sometimes, after a few attemps we get a correct file.
We've tried rebooting fcpx, rebooting the whole machine, ditching render files, none of this guarantees us a perfect result.
Our leader is made of a Generator created in Motion for the slate, followed by a clip of Bars and Tone followed by more of the same generator followed by a self contained countdown built in Motion.
As Generators in Motion are sometimes buggy we suspected this as the source of the problem but we've had the same out of sync experience without using the leader...
help would be welcome as we can not accept a one frame out of sync master file and we need to have absolute trust in the exports we produce.
thanks

Did you talk with AJA before upgrading? What do they say are the most current supported versions of OSX, FCP & QT?

Out of sync export...

hallo, i was working with FCP 2 and exported a audio track to soundtrack pro 2...i was familier to soundtrack pro, and used it for very simple modifications...but this was my first run in with soundtrack pro 2...anyway, i exported to soundtrack with any hitches, threw a limitor on the voice over, and cut out some inhales and exhale sounds, and exported the file...i oped it up in FCP 2 and the cuts i had made were out of sync...are there any clear reasons for this. is this a common problem, i only tried it with this one file and resorted to FCP for my sound work, but i found it strange and thought i would ask for a little feedback..
i appreciate the help,
aaron

I have found the tempo change to do weird things, and to make the playback warble. After deciding I did not like how GB affected the playback I tried to change the tempo back. Everything went out of sync. Tried this, tried that... eventually I closed the song file and re-opened it. Ahhh, sounded okay. I didn't do a Save, fortunately, after tinkering with the tempo.
I think there is something "not screwed down" when it comes to tempo in GB. I doesn't seem to handle the operation very well, and as you see by my experience, can go haywire with the song file.
Solution? Another application for tempo changes. HT, would Audacity handle this?

Video / Audio out of Sync - Export

Greetings,
I've been reading through these forums for over a week now and I just can't seem to fix my problem, so I decided to try a topic myself.
My issue is the following:
- After creating a sequence and exporting it into an x264 format, which matches the source media (CBR, codec doesn't matter, tried it with several), it seems that my sound and/or video is desyncing.
I'm exporting in CBR so there should be no fluctuations in bitrate, yet it seems that when the video stands still for a while, let's say a loading screen, it gets shortened tremendously and thus the video runs in front of the audio.
This effect happens no matter what I do. I have tried a clean install, deleting scratch files, clearing the media cache, etc.
The problem does NOT occur on Sony Vegas or even Windows Movie Maker.
It seems as if stand still screens just get their duration reduced, which doesn't make a whole lot of sense.
Since I'm absolutely out of ideas on what could cause this, I hope you guys can help me.
Regards
EDIT:
Just to clarify the problem, the video runs faster than the audio. No matter if CBR or VBR, same FPS as source.

I just tried to edit those informations in my original post but it seems you were quicker on the draw so I can no longer edit it.
Here's the information.

EDIT:
I know the issue must lie with the actual encoding.
Previews of the video are perfectly syncd and rendering the same files in Sony Vegas works perfectly.

Audio out of sync after exporting into Quicktime using current settings.

Quicktime file has audio out of sync when I export to quicktime movie using current settings.
Ok for about the first few minutes then, out of sync after about 10 minutes.
I shot the footage on tape with my Sony HVR-Z7u.
My Sequence setting is the same as the format of the footage as shown below.
Pixel Aspect Ratio: HD 1440x1080
Editing Time base: 23.98
Quicktime video settings: Compressor: HDV 1080p24

I recently moved and both of my editing machines were unplugged for a couple of days until I could get them set up. After turning them back on, the problem had disappeared. Perhaps leaving the system unplugged had allowed some of the internal components to reset? That's the only thing I can think of. At any rate, the issue is gone.

Why is my video exporting out of sync with the audio?

Every time I export it (and it takes some 2 hours just to export a draft version) the video is sped up, but the audio isn't, so that the video is out of sync and at the end there's just black space with the end of the audio.
Both the video footage and the composition have the same frame rate (24p). I am exporting with Render Settings set to DV settings and output module set to Quicktime DV NTSC 48kHz
When I edit it I've been timing it to the seconds and frames because it's such a large file that I can barely RAM preview 5 seconds of it, and so it's especially frustrating that it's completely off when it exports.
Has this ever happened to anyone here?

Ahhh, right.
I'm using After Effects CS5.
The footage I'm using is in .mov format, although to be honest I'm not sure about the codec (I imported it straight to After Effects from my Canon 7D's memory card? I think it's H.264)
I also have some PNG sequences.
I used the AE Render Queue.

Audio/Video slightly out of sync after exporting media and trying to watch on iPhone

Hey adobe tech heads
So, I recently upgraded to the new Adobe Premiere Pro CC, from Premiere Pro and I have to say that there doesnt seem to be any difference to the normal functionalites. While I am merely a beginner, i suppose there are more complex features that i have yet to discover.
But let me get to the point of this discussion. I have been making a few fun videos for friends of mine of their childrens birthday parties and such. I have a Nikon D3200 which is a 24 megapixel camera for images and have been shooting 1080p for the video, which i think uses 25 frames per second. (Dont quote me on that one as i am still learning all this techno-jargon). I was, in the beginning, having a slight issue with choosing the correct sequence settings in the beginning, but eventually managed to figure out that for my Nikon, i was choosing the DSLR, 1080p, 25fps option. So far, all seemed to work well, everything synced up, rendering the files often, and creating a fun memory for the parents, of their childs birthday party.
Then is comes to exporting. I would just select "Media" and then "Export" which would bring up the Export Settings Menu. I would simply press the Queue button, and then in in the Queue section, i could choose to make a video file typically for Youtube in HD. Before posting this discussion, I did a quick youtube search, so not to waste all your time, and found this link of this guy who not only showed me that i dont need to Queue it up, and can direclty select Youtube HD from the Export Settings menu which i will try, but he also confused the #%^&$(*& out of me with all his bitrate settings talk (this part starts around the 3min and 32secs mark into his youtube tutorial) - http://www.youtube.com/watch?v=j2j5dnlDmos (The reason I am showing you this is because now, i am not sure if this is what may cause my slow phone/tablet issue)
So here is my problem - Once i edit and export the file into the youtube 1080 25fps HD option, I open this new exported file on my pc and it works fine, perfectly synced and ready to share. Once i have uploaded it to Vimeo, which is my preferred social media network, it uploads fine, and on any normal pc/laptop, there is no problem and it runs just as smoothly as when it was edited. Although i noticed that the video seems to be playing at about half a second behind the audio when trying to show someone on any iPad/tablet or any mobile phone. I recently made this clip as a tester and to be able to show you awesome braniacs, because its kinda pissing me right off, that the video isnt perfectly syncing into the audio on the phones and tablets, but works just fine on a PC/Mac. I specifically made a point to match the images up to the beats of the songs, and if you watch where the little kid climbs up the indoor rockclimbing wall, this might help you understand my frustration. check the below link on your pc/mac, and then again on your phone and you will see what i mean. I even played them simutaneously together and you can see the delayed video on the phone/tablet than on the PC/Mac.
Any help would be greatly appreciated on how to fix this, as while its doing my head in, i am sure for you guys, a simply change on my lack of tech knowlege, will probably have us all smiling! Here is the clip - https://vimeo.com/7105289
Thank guys. I look forward to your replies

First of all, when you export, you should see the dialog box that has information about the source video as well as the export. If you are shooting 25fps then you are not in the USA. If you are in the USA, look harder at your export settings.
But that isn't the problem you are facing.
Are you using the Vimeo app to play the videos on the iPad or are you just playing it in a browser? Use the app if you aren't now doing so.
I doubt that you are using anything other than AAC for your audio from what you have said about using the presets, but I have to ask. You are using AAC, right? That is what Vimeo prefers.
Have you tried turning the HD off in Vimeo to see if that clears up the problem? That will probably be fine on a smartphone. An iPad might see the difference though.
You are not going to be happy reading this Vimeo.com thread, but here it is anyway.
I don't even know what to make of this one.
In any case, you will read for yourself that you may want to change browsers on the mobile device.

Quicktime Export causing Out of Sync Audio?

I'm trying to export a self contained Quicktime movie from my timeline, and every time I try, the audio ends up being out of sync. What am I doing wrong?
The audio is set to just the defaults, 16 bit, 48khz.
Sequence settings: HDV1080p30
When I bring the final exported movie back into FCP, it plays out of sync.
Exporting through the Share feature to bluRay resulted in perfect sync audio, so I'm at a loss as to why this isn't working.
Please help!

Allright, since nobody out there seems to have the answer - I'm going to share what I discovered so that the next person will actually get an answer without having to spend hours and hours finding it in other forums. Here goes:
Problem: Audio plays in sync on the timeline, an export from the timeline through Share to bluRay results in correctly synced audio; but a Quicktime Export with current settings results in a final movie where audio is out of sync with the video.
Solutions: I found two solutions to this problem:
1- When exporting to Quicktime Movie, check "recompress all frames". This solution had mixed reviews, with lots of people saying you should never do this, as it will reduce the quality of your final output; while others said the reduction in quality was not noticeable to the naked eye. I guess you can try it and be the judge.
2- In your sequence settings, change the compression setting to Apple Pro Res. This is the setting I decided to go with, as I'm currently awaiting the 10 hour render.
I did do a quick and dirty test on the ProRes option, where it appeared to work. Since the audio is correctly synced in the beginning of the video and then slowly falls out of sync (obviously the 30p to 29.97 problem), I had to run a test using my entire sequence. If you run a test on a 2 minute sequence, it will appear to be correct, because it is a slow falling out of sync issue - the problems occur later in your project (just fyi). Here is what I did (in case you want to try it on your project):
I created a new sequence and then changed the compression setting from HDV1080-30p to Apple Pro Res 422. I dragged my sequences into this sequence (so they were nested). I unlinked the audio and then selected about a 20 second area from about 3/4 of the way through the project. I sliced this section and then removed all the video before and after (so it would speed up render time and only render black, but I would still be able to see if the audio synced up later - I hope that makes sense - this made my export time only 12 minutes). After it exported, I reimported the movie, found the little 20 second area, and it was correctly synced. So, now I am exporting the whole thing. I sincerely hope this works. I don't have lots of 10 hour blocks just lyin' around!
Since my audio issue was most likely due to the fact that I captured and edited in 1080 30p, I believe it must be a bug in FCP that exports the Quicktime movie in 29.97 regardless of whatever your sequence settings are (believe me, I tried to change it to 1080-30p and it didn't work). That is why I think the Apple Pro Res option works, but it involves a total re-render of your project. This is also why I believe it plays fine in the timeline, because my timeline was set to 30p. Again, I also believe that is why my export to BluRay through Share resulted in correctly synced audio - the bluRay export I believe uses the Pro Res codec (which, by the way, took 19 hours).
Wish Apple would fix this bug.

Audio and Video out of Sync after Pro Res export

I´m getting an audio/video sync issue when I´m exporting to Pro Res.
I started off in a HDV1080i50 sequence. Audio sampling rate is 48khz. (16 bit depth)
The sequence is less than 20 minutes long. It plays correctly on the timeline.
When I export the sequence for DVD and view it on a set top it plays absolutely fine.
When I export the video to ProRes (422 HQ - I used Export using Quicktime Conversion) and the audio to AIFF, they quickly go out of sync. This was brought to my attention first by the guys who were making the DigiBeta master, and when I view the exported material in a Pro Res sequence I can see it for myself.
The audio and video clips are of the exact same duration.
Possible issues...
Some of the narration was recorded at 44.1 khz. I didn´t resample it (I´m still a learning novice..).. but if that is the issue should it not have affected the DVD as well? All the other audio in the project is 48khz.
Most of the material is HDV1080i50..but one clip used was originally an NTSC clip and therefore a different frame rate. However I converted it to a 25fps clip and this is reflected in the vid rate column in the browser where it says 25fps.
Final point, the exported AIFF files..when I import them back into the HDV1080i50 sequence and play back, it is perfectly in sync.
Any help would be greatly appreciated.

First, yes resample the narration to 48k 16 bit. You will probably be able to reconnect to the resampled files. Usually works for me. That's a simple fix and will probably solve the problem. If it doesn't, you can try to change the codec (compressor) in the sequence settings to prores 422HQ, fully render and see if that solves the problem.
Wait, just reread your original post. Export from fcp using file: export: quicktime movie NOT quicktime conversion with current settings. If that works without synch issues, use compressor to convert to prores.

Audio and video out of sync after exporting sequence

I'm a FCP user since years, but not so common with HD footage. Therefore I have an issue with my finished edited movie after exporting: Video and Audio are out of sync.
My sequence settings are: HDV1080i50, 25fps, 48kHz, 16bit, Stereo. I used File-> Export-> Quicktime Movie -> Current Settings
Sequence has a duration of 61 minutes and 38 sec. I tried to find out where's the problem and exported audio and video seperated. This results in:
Video is 61 minutes and 27 sec long
Audio is 61 minutes and 38 sec long
That means exported video is shorter than original sequence.
What could that be ?

I had the same problem with a Panasonic camera, even filming at 30 fps. I was able to fix it; see [this thread|http://discussions.apple.com/thread.jspa?threadID=1783029&tstart=0]. It's a frustating problem, to be sure. You might have to use Easy Setup a couple times before you get things to work properly. Not sure why that's the case.
Good luck!

Why does my audio slip out of sync when exporting?

I am exporting an HD edited video. I shot 1280x720 & editing in FCP 6.0.5. I am using APPLE PRO RES 422 1280x720 30fps 48kz . Should it be (HQ)?? - I do not select re-compress all frames or make self-contained. I just want a QT reference file to view and then burn a DVD. My clip is 43 minutes long. HOWEVER, the audio drifts out of sync BIG TIME. Why is that??
Here are my sequence settings:
1280x720 Aspect Ratio HDTV 720p (16:9)
Square Pixels
H.264
Audio at 48kHz

That's what I thought, however, when I play back the .mov file after exporting using "current settings", that's when I experience OUT OF SYNC audio. Do I ignore that and drag and drop that file into iDVD and let iDVD crunch it??? Is it just the playback of that .mov file that is out of sync?

Some audio out of sync in after Export

Can using the built in Audio tools like Loudness, or adjusting the sound levels in the waveform cause the audio to go out of sync?
I'd say not...but that is what seems to be happening.
I have a 2hr 30 projet for a DVD.
All individual clips captured on Canon 5d 3 at 48khz 25fps
Project is 48khz 25fp, as set automatically when the clips were first dropped on the timeline
One particular group of 3 clips, seems to randomly and suddenly loose sync in the middle, sometimes at the start, some times in the centre, then often it comes back at the end.
Of the whole 2 hr 30 project only this bit is giving issues, all other clips have been edited in the same way, and are similar lengths,some longer, some shorter, all stay in sync. Max clip length about 8 minutes
In the timeline the audio stays perfectly in sync
I have re made the sequence of three clips , totalling 24 minutes long, probably 6 times now. and each time after adjusting the audio levels the exported audio has variable sync,
Also re imported the footage and tried again
No added audio tracks, just a single compound clip containing three complete clips, with the ends trimmed
Audio has not bee detached from the video.
All I am doing is adjusting the audio levels,
Hum On
Noise reduction to about 2%
Loudness On :
Amount 20%
Uniformity 15%
First noticed this yesterday on a DVD burnt using "Send To Compressor" Create DVD
Also happens using the in built Share, to DVD, ot share To master File
Output settings are also 48khz and 25fps
If I do an export of the clip With no audio corrections, it is fine. But as son as I try and adjust the audio levels, it goes out of sync.
I'd half suspected I had somehow dragged the audio in the timeline, when adjusting the levels, but no. Go back and play the clip in the timeline and it is perfect. But Share that compound by dropping in to a New project, export as master and Playback in QT and the audio goes out of sync after I have done a levels correction. Un-corrected ( for level only ) audio stays in sync.

How are you exporting? The first quicktime export option or quicktime conversion? What are your settings for the export?
Did you capture with device control with abort capture on dropped frames and create new clip on timecode break enabled?

Final Export of a Project Slightly Out Of Sync

Hi there,
I'm trying to find an answer to what seems to be a common issue when exporting projects out of Final Cut Pro X, however I haven't yet found any answers that work or that tell me things I don't already know (don't mean to sound know-it-all though).
The issue is that after I have exported my project, the audio and video are out of sync. It doesn't drift as the video goes on; it's out of sync by the same amount from start to end. Of course, when editing and viewing the project in Final Cut, the sync is fine.
The project was created from scratch with the Apple ProRes 422 setting, the two original camera angles were both 25p, the audio I'm using is 48K/24bit which the project is setup as also. The audio was originally recorded at 48k/24bit and mixed seperately in Pro Tools and was exported as a wave file (48K/24bit) and brought back into Final Cut.
I can't think of what else to describe. All the project settings and the original footage and audio setting are exactly matched. There's no frame rate changes, no audio resolution changes, no MP3 in the mix, no apparent issue when viewing/editiing in the project, and I even tried optimising the video and exporting just to see if that made any difference.
I usually listen to the audio via an RME souncard which is setup to be low latency. However, whether I view the project and then export via the external audio interface, or view the project and export via the laptop speakers (with not extrernal audio interface connected) it's the same result: slightly out of sync video!
If anyone has any ideas I would be most grateful.
Cheers,
Chris

Hey Russ,
Thanks for your time. When I say a 'common issue' I found that when I searched it both on Google as well as this support forum I found multiple threads and questions pertaining to this issue of sync and/or drift.
I tested this single angle idea by using the footage in a nother project and exporting part of that (without changing angles) and it seemed to be OK. However I have other projects which are only single angle but they export slightly out of sync as well. I haven't found a common denominator yet.
When I say out of sync, it's not dramatic, however it's always the same - the audio is just a few frames behind the video. This has happened with most of my projects using different footage and different audio, etc. No matter what setting audio and video are recorded at, and regardless of whether I dramaticallty colourise or add effects to the video or not, it's always the same result; slightly behind audio when exported.
With regard to presets, do you meet export settings? If so, I'm mostly exporting using H.264 and as a Quicktime Move (AAC) output. I've tried various resolution changes and tinkering but nothing has changed.
If you're referring to project setup presets, I can't really change too many things because obviously the audio resolution and video frame rates are predetermined so I can't try 25p footage in a 30p project, etc.
Thanks again,
Chris

Export out of sync, plays fine in FCP

I'm working on a short movie for a class I'm in, and everything shows up and plays fine when open the file in Final Cut, but for some reason, it doesn't want to export properly. Whenever I export, no matter what settings I've chosen, the audio and video become out of sync in the exported file, but strangely only for clips where we've chosen a different audio track from the original recording. The first clip, which uses the audio and video from the camera, works fine when exported, but for each subsequent clip, the audio starts close to synced, then gets further and further out of sync. Even more baffling, the final clip, which is done the same as all the others, with video playing and an external audio track synced to it, works fine again!
I'm pretty sure that the problem is with the video, as it seems to slow or have parts cut out of it in the rendered file.
Anybody have any ideas what could knock the video out of sync like that when rendering?

Exporting from iMovie 08 falls out of sync

Ive been stuggling with iMovie 08 for 5 days now trying to get a 12 minute movie exported without audio syncing issues. By the end of the exported movie.. the lips are detectably off sync with the audio. Im blow away how Ive gone through all possible export settings I can think of to no avail.
This is HD tape...
Anybody able to sync their exported movies with perfect sync?
Tell me your exported settings PLEASE!
Thanks

Check your audio codec for your source material.
You can do this by opening it in Quicktime Player and selecting Window/Quicktime Inspector.
If your audio codec is 12 bit, it will frequently get out of sync. The solution is to use a 16 bit codec. Or run your source files through QT Pro and export as 16 bit.
