Motion project exports out of sync

Hi - I'm quite new to motion and have just learned to use it for keying - however I'm quite perplexed by the fact that whenever I export my finished project, it plays back out of sync. I am working at HDV 1080i50 mode, (fairly certain there is nothing telling the machine it's NTSC or anything...)
Does anyone have any ideas?
Best wishes, Dan

HDV files are probably to hefty to be using in Motion. Try exporting them as Pro Res and reconnecting them. You could also try to bring the Motion Project into FCP and exporting from there.... On other thoughts, does your project have a separate audio file being used? If so, You might want to export the audio file as another format or change it's bit rate.

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

FCP Send To STP Multitrack Project - Audio out of sync

I'm editing video in FCP and sent the audio as a multitrack project to STP and upon opening it in STP the audio is already out of sync - even without touching it. I thought maybe it would go back in sync upon sending it back to FCP, but it stays out of sync there too.
It appears I'm having the same problem as this person who created a screencast on how to fix it: http://www.screencast.com/users/hatuckett/folders/Default/media/d781e0cb-8689-44 4e-9c49-7e8592e86052 I tried their solution and for whatever reason it doesn't work for me.
This isn't just happening with 1 video or project, it's happening with ALL of them. All of my video is PAL. I'm using PAL video and I've made certain in STP in the Project Preferences setting to change the videos frames per second to 23.98. Yet, the audio remains out of sync. Is there anything else I can do to insure that the audio file when imported and exported in and out of STP remains in sync with the original FCP video?
I am using Soundtrack Pro 3.0.1 and FCP 7.0.2. Thanks in advance.

There is a mismatch somewhere which is causing this sync problem.
Next thing to try - does your STP project sample rate match the sample rate of the audio in your FCP project?
In the STP project, on the projects tab, is "none" selected in the pullup/pulldown section, both audio and video?
In some cases, changing a frame rate can change the speed of the video, causing sync problems, so the earlier discussion about frame rates wasn't just semantics or terminology issues. I understand your frustration, but I was trying to help by ruling frame rate problems out.

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?

Flip4mac exports out of sync

Hi all,
Suddenly, when I export WMVs using QT Converter (flip4mac) my clips end up out of sync. Any help would be appreciated - Steve

When I export a wmv the audio is always from the beginning of the sequence, regardless of where the in and out points are. For example, if I export a 30sec spot that's third in a sequence, the audio will be from the first spot. Or in my most recent try, tone from the bars that were at the beginning. I also get the other problems mentioned - it hangs up at 98% finished and the file sizes are three to four times as large.
I've had this problem for a few weeks, and it didn't go away after upgrading FCS and the OS last week.

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.

Deleting Scenes - Project goes out of sync !!

When I delete a scene from my project, the music and titles go out of sync. How can I delete a scene without affecting the rest of the project. TIA

I find it hard to believe that you shouldn't change your album as iMovie '08 handled it perfectly fine and never got the thumbnails muddled up.
Seems strange that it's working as designed. I can only assume there are some extra behind the scenes processing that now occurs when prevents the user from ever changing the album. Interesting.

HD 1080i export out of sync

I'm exporting a HDV 48khz project to a quicktime.mov problem is once I get the export and play it, the sound is drifting along the project. It's not like it's out 2 seconds and I can slide it back into sync by making a 2 second adjustment, it has a different drift as the project progresses. It was captured at HDV 48 sequences HDV 48 and it plays perfectly in the timeline but when I export, it drifts. It is a long program 13 scenes over 3:10 but it's broken into 13 scenes.
I'm making an attempt to limit the file size to 2 gigs now, we'll see.
Anybody?????? Help PLEASE!!!! before I throw this computer out the window and take a hammer to it after it pathetically smashes into pieces on the sidewalk.
Thanx
Cal

What's the sampling rate of the clips and what's the sampling rate of the sequence. Although fcp SHOULD be able to resample on the fly, this might be the root of the problem.

Project Structures out of Sync on a Shared Project

Hi All,
We are on 12.2.3. Facing a Problem with Syncing Project Structures for a Shared Project. Workplan is not reflecting the Financial Structure created with multiple hierarchy levels. Let me know if you have seen this issue before.

QT exports out of sync

Hi
I have a 1:32 clip that I exported as a QT file. When it finsihes the length is only 1 minute 30 sec. The video is all there but the audio is cut off. THe audio is wav format 48K.
Any ideas why this happens?
Message was edited by: rnnyc

I think I solved it. I copied all the clips on the sequence, opened a new sequence, deleted the render files and pasted the clips on the new sequence.
Seems to work now

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?

Audio goes out of sync when Blu-ray folder is exported from Encore CS6

I compile a project in Encore using H.264 and .wav files. The audio plays fine directly from the timeline. It also plays fine when I preview it from Encore. When I finally export it as a set of Blu-ray folders, the audio exports out of sync with the video. It is approximately 6-7 seconds ahead of the video. What am I doing incorrectly? When I mux the files into an .MKV, the video is in sync with the audio so I know the files themselves do not have different start times.
I am running with an HP Z820 with Windows 7, 64-bit OS and 16GB RAM.

For anyone who's interested, I found a solution to this problem. Once imported into Encore, the leader in on the video and audio files cannot be trimmed at all. (I had been trimming the beginning of the video and matching audio file to eliminate the 8 seconds of dead space at the start of the clips.) Although the trim took effect immediately in the Encore timeline and I could also watch it in preview in sync, exporting was another story. The audio track seems to retain the trim when exporting but the video track does not, hence the 6-7 second delay between audio and video.
I reimported the files to my project and left in the 8 seconds of dead space at the start and voila! The video and audio match up when exported.
Ideally the trim tool would just work as its supposed to through export and all, but at least I found a solution I can work with.
(As a note, the trim works just fine in export on Encore CS5. I only had this problem with Encore CS6.)

Stuttering and Out of Sync Playback in Logic Pro X

I'm having a problem with my playback.
About 1 of every 4 times I play back audio, Logic experiences stuttering; portions glitch up and the output cuts in and out.
Then the project plays out of sync for a few seconds before the system recovers.
This is happening on very simple scratch projects with 4 tracks or less, and about once every 4 times I hit play (which is unacceptable in my mind).
It also happens during recording which is very frustrating.
All my drivers are up to date, I've used disk utility to clean my system and repair permissions, and I have a very fast and current computer.
My projects are on my internal drive, and set at 96khz 24-bit; but again, these are very simple tracks running off of a "blazing fast" PCIE solid-state drive.
I'm beginning to think this is a hardware problem, as I experience pops and clicks when I first play any audio on any app after the system has been idle. The cut out effect also occurs with iTunes once in a blue moon.
Thoughts?

What is Logic's I/O Buffer set at?
Not sure what you're using for an audio Interface but 96kHz is overkill. Unless you have a pristine listening room, many $$$ worth of monitor speakers and amplifier... the best mics, instruments, yes in can make a difference with soft instruments + a lot of effects but even then. I hope you have a high end audio interface otherwise it's pointless and unnecessarily hard on your system. Also, recent versions of OSX do a lot of writing to the drive. What make is the solid state drive, there is a known issue with some recent Samsung drives.
Logic does better running loops/recording/playback from a separate drive although it normally should be able to handle a few tracks. Are you running any applications in the background? If so close them.

Decklink Sp A/V out of sync!

I am digitizing beta sp with the decklink sp to a g-raid 500 drive. at first everything was synced, but now all of my timelines in various projects are out of sync. But i cant tell if its "really" out or if its just bogging down, so i dont want to mess with it. my drive is half full.
Whats up?
thanks

I am having exactly the same problem, but mine is with decklink and digibeta. I just upgraded to 5 and osx.

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.
