Processing in STP causes out-of-sync in FCP

Mixing multitrack live band performances. After sending tracks to Soundtrack Pro for normalization, EQing, effecting etc. and round tripping back to FCP they now get out of sync with live performance video over the course of time.
Doesn't happen if I use FCP audio filters directly on the clips in timeline - but FCP's effects are so much more crude and limited. Is there a way to make Emagic's plug-ins from Logic (now also used in Soundtrack Pro) available directly in FCP ??

Having the same problem. A 4 minute song recorded from the deck during performance doesn't sync with the video footage after time. Anybody got any tips or this? Was working perfectly up until yesterday, no sync probs at all. I went in to do another mix and it's all gone pear-shaped.

Audio falls out of sync with FCP sequence after export from STP

Hey all,
editing sound on a short film. sent FCP sequence to sweeten the dialog and add effects, according to the timeline it is the same length as sequence length in
FCP, but when exporting from STP to FCP to complete movie, the sound ends up being about 10 frames longer than the video and starts in sync and falls out of sync over the duration of the film.
Have tried changing preference settings in STP, exported about 5 ways to breakfast and all have same result.
Anyone have a solution to this problem?
Much thanks,
Holly

I just experienced this same thing, and as Christof says, it had to do with 'Easy Setup' and 'all formats'. I've been editing a picture shot on RED in Apple ProRes 422 (HQ) at 2K (2048 x 1152) and 24fps...FCS 3 (FCP 7 latest version). Whenever you trash preferences or start up FCP new, you get the 'easy setup' menu. Previously, I could just hit 'okay' and go ahead into FCP and change the settings/resolutions within the project...even if the 'easy setup' default was, say, DV/NTSC 29.97. Also, when opening up an active project after trashing prefs, the project itself would still have the same editing/playback settings/resolutions, even if the 'easy setup' window had its default DV/NTSC setting. Plus, if you create a new timeline and its default is one format, once you drop a different format into it, it asks you if it should adjust to that format anyway, and of course, you say yes and everything is fine.
Well....in this most recent FCP update, whenever I'd export an AIFF from the timeline and reimport....or if I'd just import an AIFF...it would do something to the playback rate of that newly imported/reimported sound file and suddenly its sync has drifted all over the place within just a minute or so. But strangely, it wouldn't do it to audio that's attached to picture (.mov/MP4/etc.)....only isolated audio files (AIFF/WAV). So naturally, I wondered if something was going on during the export process or the like.
The solution is to make sure that when you open FCP (newly, or after trashing prefs), make sure you pick the settings/format/framerate in that 'Easy Setup' window that matches what you intend to edit as closely as possible. In my case, the format is Apple ProRes 422 (HQ), 2048 x 1152 @ 24fps, and I use a Blackmagic Multibridge so I have settings for it. Hence......*Format; HD, Frame Rate: 24, Use: Blackmagic HDTV 1080P 24 - 10 bit.* Whereas the default upon startup is....Format: (all formats), Frame Rate: 29.97, Use: DV/NTSC 48KHz.
You can also set these in the 'Audio Video Settings' menu. Now, whenever I export and reimport an AIFF, or just import an AIFF (like the soundmix prepared by our sound designer), sync stays and there's no drift. So make sure you've picked the right settings when starting or reopening a project, again as Christof pointed out.

Exported mixes from STP drift out of sync

STP seems to have a mind of it's own. Mixes that use to export fine are now drifting out of sync over time, about 2 seconds over fifteen minutes. If I export the mix either directly from STP or through Compressor, it drifts.
However if I export with video (through Compressor), the audio is in sync properly.
Does anyone on the STP team have a clue as to what this might be? It's driving us nuts!
Michael Buday

Thanks Gavin. I often do the same thing, export projects with a large number of tracks through Compressor because exporting directly from STP is just too unreliable (missing EFX, keyframe levels/pans missed entirely, etc.)
I tried exporting as usual through Compressor using the standard 48:16 preset, but again - drift. When I then switched to PRESERVE VIDEO with the same audio settings, the sync was fine. This is a workaround, but a real pain in the butt because I then have to extract the audio out of the .mov file. Not rocket science, but just too many steps to do all the time.
The weird thing is, this has happened only three times out of about 50 projects, but once it occurs, it's as if the project is corrupted in some way and it never exports properly again.

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.

Send to STP makes audio out of sync on FCP (TC 30)

Good day
I REALLY hope someone can help me because i am really struggling at the moment
When i say send to Sound track pro audio project i fix the audio and do what i need to do but once i save the audio a green line appears above the sent audio and the audio down the line is out of sync.
Now i can work out why it is out of sync but i have NO idea how to change the TC(timecode) rate on fcp so that it is 25 instead of 30, i have set everything to 25 but yet whenever my send audio comes back it arrives as TC 30
Can someone please help me? or just give me a workaround that won't take excessive amounts of time?
What i do notice though is it is only the pal guys experiencing problems.
Peder

It'd be nice is someone from Apple would care to comment on this phenomena.
The only feedback you will ever get from Apple on this forum, or any other, is that your post has been removed for inappropriate behaviour. You can use the "Provide Feedback" button under the application title menu. Your report will be evaluated and prioritized -- ie "Will this affect the sales performance of the iPhone?" and dealt with accordingly.
Then the issue may or may not be fixed with the next version.
There is probably a subset of rules associated with exporting Multiclips, even in COLOR 1.5. Of course they are completely incompatible with previous versions for starters, but with the current release, you're probably prohibited from exporting multiclips with any speed changes, filters or transition effects... something like that.
I never, never, never, never use them period. Realistically, if you cannot lock the edit and export a Media Managed version, then you're equally not likely to be ready to go to color grade, either.

Anyone noticed Quicktime 7.4.5 causing out of sync issues for online vids?

Since 7.4.5 all Quicktime video clips I view online in Safari have audio out of sync with the video (by perhaps four frames). Anyone else seeing this?

I do not use Safari. However, I have no problems w/out of sync issues using the +latest versions+ of FF, Camino & Netscape.
Have you tried other browsers to rule out Safari as being the culprit rather than QT? Are you using the latest version of Safari?
What troubleshooting methods have you tried to resolve your issue? Need this info to avoid the +"been there done that"+ senareos.

Captured 24A footage wildly out of sync in FCP, but fine in QT

I just captured a bunch of 24A footage I shot on my Panasonic DVX100A and was dismayed to find that the clips were all wildly out of sync when I opened them in FCP--even though they are fine when I open the captured files directly in QT on my desktop. But when I play these same clips in FCP, the audio slips so steadily out of sync that on one 47 minute take, the video ended seven minutes before the audio, so the clip ends with seven minutes of sound against a black screen!
I actually found a workaround for this problem in a thread started by another poster with a similar sync problem. On that thread someone suggested that if I simply opened the underlying file as a QT movie on my desktop and then edited a second or two from the beginning, and saved it as a new Self Contained QT movie, I could import that one into FCP and it would have no sync issues. For reasons I still don't quite understand, that workaround solved the problem almost every time.
Until now, when not even that convoluted solution seems to help with this latest clip. Even after shaving the ends and saving it with a new name, the resultant QT file still imports into FCP with the same off sync problem.
Obviously, the best solution would be to figure out why clips are capturing with bad sync in the first place. For the record, I've shot and captured many, many hours of 24A footage from this camera in the past without experiencing any syn issues. As far as I can tell, the audio was shot and captured at 48.0 KHZ, just like always. (And the out of sync clip shows up as having 48.0 KHZ audio in the FCP browser.)
Since it was shot at 24A, I captured it using Advanced Pulldown removal as always. (Oddly, I notice in the browser info window that the clip shows up as 29.97 fps and not 23.98--if that's a clue to anyone.)
Thanks for your guidance on a sticky issue that has me stopped in my tracks.

Hello GeeFor,
I was browsing for a different audio sync issue and came across your post. It caught my attention because I believe that I've ran into the same problem before and figured out what causes it, so I thought I'd share my experience.
You said that you've noticed that FCP initially recognizes the problem clips as 29.97, even though you've captured the 24PA footage with Advanced Pulldown. I've found that if, while you are capturing 24PA footage, you allow the capture to go beyond the recorded footage and into blank tape, that FCP recognizes the entire clip as 29.97. This causes audio sync problems, and if you end up trying to do a final export, will cause video problems as well.
I've successfully duplicated this problem and the solution is to make sure to stop your capture before your 24PA footage ends and blank tape begins. One way to avoid the problem is to record black to the entire tape while on the 24PA setting prior to filming. I normally just record an extra minute or two while on location at the end of the footage.
I think your work around in Quicktime works because you are effectively removing the break in timecode at the end of the clip, therefore FCP sees a start and end timecode that matches the 24PA settings.
I hope this fixes your issue, I'd be curious to know if it does. I did a lot of trial and error to figure out what my problem/solution was and I couldn't find anything in the forums that helped with my particular issue.

Out of Sync in FCP

I captured some footage for an edit. 10 tapes all together, miniDV. the last tape is totally out of sync when brought into Final Cut, both in the Viewer and Timeline. Its plays perfectly fine when opened with Quicktime in the Finder.
Only when I bring it into FCP will it go nuts. I can't even slide the audio into sync because I believe the video speed is changed somehow in FCP. Any solution to this?
audio rate 48khz.

Non Drop frame capture causing out of sync clip?

Hi, All,
I've been having trouble with sync issues on an hour long tape capture.
The material was captured from a Canon consumer DV cam (z80) using firewire into my powerbook g4. (The material on the dv tape was originally recorded in Video 8mm and transfered to the Canon via firewire from a modern Sony Digital 8 camera.)
The sync on the DV tape looks fine when I play it back through the Canon camera. So I'm guessing that I might be losing sync because the camera is dropping frames that don't want to be dropped. I tried to change the video capture settings to non drop frame (in the device control tab of FCP5's audio video settings preference window,) but as soon as I start the capture from the canon, the settings on my log capture window automatically revert back to drop frame. (I don't know this for a fact, but I do notice that the ":" in the timecode box turns back to ";" every time I start the capture.
Does this sound like it is, in fact, a drop frame problem? And if so, is there any hope of getting a canon consumer camcorder to capture at non drop frame rates?

Well, after trying most of the suggestions here, I did find a reasonably hassle free workaround to capturing the hour and fifteen minute footage of 8 bit 32 kHz video to FCP with minimal sync slippage over the length of the footage.
I finally gave up on capturing the material in FCP and instead hooked the canon z80 up to an old version of Toast Platinum 6 I had on my computer. Toast creates a raw quicktime movie file with the extension .dv. Toast then allows you to edit that quicktime file, add chapters, button pictures, etc. thereby making a new file to replace the raw QT it first created. After some experimentation, I discovered that the original raw QT file Toast creates can simply be dragged intact to the FCP browser window, where it becomes a clip with minimal sync problems. I would caution against trying to use the second improved QT file that Toast creates after you've edited your file, as this second QT movie seems less stable than the raw one it first creates.
A final caveat for Toast users. Make sure you set the preferences so that they don't DELETE the original file it creates. There are settings that will tell Toast to do just that either After a Day, After a Week, When You Close the Program or Never. I'd set that to Never, since it can be highly unpleasant to discover that your program has deleted the very file you were planning to work with.
Hope this is of some help.
Thanks to all who pitched in and offered suggestions. Your help has been invaluable!
I now mark this issue Solved. Or at least as Solved as I plan to get it!

Captured audio is out of sync

I captured a 12 minutes clip using Capture Now in FCE 3.5 from my PAL camcorder Canon MVX4i (=Optura 600).
This is the first time it happens to me: the captured clip has the audio portion out of sync with respect to the video by 5 frames. So, the audio is consistently 5/25 fps = 0.2 seconds late during the whole clip. Unfortunately, this is quite visible when people are speaking.
As a workaround I set the clip in the timeline, unlinked the audio, shifted the video portion forward by 5 frames, marked the clip in sync and relinked (BTW it took me a while to find out that 5 was the right value: lot of tests adding and subtracting a frame at the time, and listening ...)
I doubt the cause is the camera, so my question is: what is the cause of this out of sync ?
Thanks
Piero
Some additional info.
I used the same setup I've been using so far: camera directly connected to the iMac, capture to an external firewire hard drive, use of Capture Now just because it's faster with short movies. Tha movie was shot with 16 bit audio. The shift is the same all along the clip.

Hi Ian,
I'll check tonight once more, just to be sure. I doubt though, because being aware of the possible impact of the 32KHz, I am usually careful. But I also know that editing after 11 pm is not recommended to me... I might do silly mistakes...
In any case, I'm afraid there is a problem with the tape. Could a damaged tape causes out of sync during capture ?
Thanks
Piero

Audio out-of-sync in Vimeo Flash player in Firefox

I sometimes get reports that videos in Vimeo's Flash player play slightly out of sync in Firefox, but not in other browsers (even with the same version of Flash installed). I've contacted Adobe about this issue as well, but wanted to check if there were any known interactions between Firefox / Adobe Flash that could cause out-of-sync video?

You can advice them to check for problems with current Flash plugin versions and try these:
*disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
*disable protected mode in Flash 11.3 and later
*disable hardware acceleration in the Flash plugin

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.

FCP to STP back to FCP now video out of sync

I exported from FCP to STP via multitrack, did my audio edits, then exported back to FCP via xml import. Three video clips in FCP are now out of sequence (they are completely different, like they have different I/O points. These clips are only 1 second long .
Any ideas on why?

I hate when someone doesn't first search threads for answers before posting. That would be ME late last night. After searching, I don't find definitive answers to my issues.
I am using DV NSTC 48Khz preset in FCP.
The FCP Easy setup: Format NTSC, Rate (all rates)
In STP, Preferences, synchronization, frame rate is 30 non-drop. Is this correct?
What is 30/29.97/Drop Frame?
Could this cause my video clips to come back to FCP out of sync and have the wrong I/O points.
I would really like to use STP instead of just doing the sound in FCP.

Clips from Project bin to source monitor causing video output to go out of sync(CS6 and CC)

Any footage I double-click or drag from the Project window to the Source monitor causes my video output to go out of sync. When I put the clips in the timeline, video goes back in sync and I'm able to view video output. My monitors are connected to a Blackmagic Intensity Shuttle Thunderbolt(9.7.5) via component and HDMI. Is this normal behavior in Premiere or is there a setting to enable this? No issues doing this in FCP7(clips from Project window to Canvas).
Can someone with an I/O from AJA, Matrox, or Blackmagic please test this out for me. Thanks...

Hi Joe,
How do you have your audio setup? Try the following.
- Set your OS system sound to Built-in or Line out audio
- Select Blackmagic for both Video and Audio in Preferences> Playback
- Select System Default Input/Output from Preferences> Audio Hardware
Hope this helps,

Conform process all out of sync.

I can't tell if I'm doing something wrong, or if it's just STP being buggy, but when I try to conform a project to a new version, the audio files get all out of sync!
I have a 4-minute video that I already mixed in STP. I made one change to the video in FCP, lengthening a single clip somewhere in the middle. I re-exported to STP, and conformed the old project to the new stmp file. When I do this, all of the clips after the new edit are out-of-sync. Some of them moved, some of them slipped. Even if I click on the 'un-modify' buttons in the conform window, none of the options get the clips back into sync. I'm using the "fully rendered video" option out of FCP to make sure the video is right.
It's really slowing me down to have to re-mix and master the audio every time I make a small change to the video. Am I doing something wrong here?

Hi T-Bob,
You and me both. A near-3 hour programme here, with a slight nip in the middle, conforming the oh-so-long dub should have been easy... instead, hundreds of sync-slipped audio clips, clicks appearing from nowhere... easy it isn't.
In the end, I'm having to re-dub the whole 3 hours again.
No one can help?
