FCP Audio Sync Loss

I am using Final Cut Pro 5.0.4. I just loaded Leopard and now my audio sync is at least 20 frames off. All clips before the Leopard upgrade work just fine but any new clips are not sync'd.
Does FCP 5.0.4 not work with Leopard..... if so, will udgrading to Fianl Cut Studio 2 solve this problem.
Thanks.

can't you upgrade to FCP 5.1.4? that is the latest FCP version of 5.

FCP: AUDIO SYNC PROBLEM

i have audio sync problem -- of the finished product which didn't have that problem before. does anyone know how this could have happened? in my earlier posting, there was a warning window which i played around w/ and now i have an audio sync problem in my prior projects.
please help me.

The Reels, are indeed the 5 surround channels. I have a feature that is broken up into 8-10 minute sections. I did this because the composer was using a G3 at the time and couldn't handle the whole movie at once. They are 16bit 48khz aif files exported from ProTools. The biggest thing here, is that at one point everything was in sync. I am trashing the preference files now to see how that works.
It's not a playback issue as well. When i scrub one frame at a time, the sync has drifted off later in the clip. It's very strange.
In my previous post I said the one of the Reels was in sync. That was because I recreated it, by making a new project and copying the video from the timeline, and re-importing the 5 audio streams. It didn't work for any other reels though. it is still out of sync in the main project.
Trashing prefs did not work.
Also, I tried a lot of the things in that technical doc, but non of them worked including trashing prefs.
The real weird part is that the Audio file SAYS it is the same length of the video, but the audio ends later. It's in sync in the beginning but not at the end.

FCP audio sync issue, attempts at fix result in dodgy files - help!

Hello,
I have some Sony EX1 footage here in which 20 out of 500 QT files FCP will play the audio out of sync by either 14 or 19 frames (picture lags) - when shooting no changes were made to settings which were as follows:
1080/25P HQ 16-bit 48Khz
weird thing #1: only FCP will exhibit the out of sync problem, QT or even quickview in the OS X finder will play them back fine ...
weird thing #2: once I export the footage without re-syncing it it will then play fine again in QT/finder and will sync fine in FCP - yay! - no... it will beach ball and/or lag/crash FCP/QT/finder once I attempt any sort of movement/scrubbing in any of the timelines
attempting to work with the original un-synced footage and unlinking the audio (and correctly syncing it) as a workaround has failed as whenever I put on any video effect/transition or whatever the effected part will sync correctly and my smarty pants re-sync therefore makes it out of sync again ! arrrrgh!
Basically, anytime I effect or export it the sync issue goes away, but I am left with crashy/corrupted files ...
Any suggestions ?

the audio clip is the same length as the video clip. it is not a matter of moving the audio over to sync it up. the audio falls behind by the time it gets to the end. it is just fine at the start of the video and out of sync at the end. If I would sync up the end then the front will be out of sync. All I did is capture the footage from my deck to FCP and then placed it in the time line.

This is not correct but it's easy to arrive at that conclusion. The two clips aree not the same length by your definition: *the audio falls behind by the time it gets to the end*
Mark the place where the audio ends, mark the place where the video ends. They are different and that difference is a simple matter of subtracting one timecode location form the other. This means the audio was shot at a different sampling rate than that with which it was captured. I do not know anything about the DSR400 camera or your deck, my Sonys are different, but you should be able to ascertain the sampling rate of the audio by checking the data display. If, indeed, it's 48k, you have sent the audio to a separate folder than the video and your disk cannot keep up. But that sync difference is not absolute so it's going to be different each time you play it back.

Audio sync loss on capture

the other day i captured a tape - pal mini-dv, 32k audio - with appropriate settings only to find afterwards that audio was totally out of sync.
throughout the entire captured material, it was 2 full seconds late!
i deleted the captured material, created a new project with the same settings as before, captured with the same settings to the same harddisk, and now everything is fine ....
i have not changed any settings, used the same hardware, i have not even restarted the machine ...
btw audio was out of sync even in qt player - so this wasn't an fcp issue either...
still got me stumped ...

Our group commonly shoots instructionals that require 4 tracks of audio on the camera, thus 32 KHz/12-bit source in DV NTSC.
I have recently found that after capturing at matching settings, that the first clip, and only the first clip of the batch capture, is out of sync by about 1.5 seconds. All the following clips are in sync. It's gotten to the point where we need to log a short "dummy clip" to capture first in the batch, just to fool the system to getting our first real clip in sync.
We are going to try setting the sequence settings to match the 32 KHz/12-bit source and see if that helps.
Otherwise, do you recommend that we resample all our footage's audio, (both stereo pairs), to 48 KHz/16-bit and use it in a default DV NTSC 48 K sequence?

Audio sync loss in iTunes 8.1.1.10

I've used iTunes on Windows (Vista) for some time now playing my music library
only.
Recently,for the first time, I downloaded a music video from the iTunes store
(Robert Palmer). Mainly because I had some gift credit to use.
But I was very dissapointed in the playback, under iTunes, the audio drifts
from the video quite noticably. With about 20 seconds it's irritatingly out
of sync.
Fortunately, since it's not DRM'd. I can play the clip using other players
E.G. VLC, where it plays in perfect sync all the way through.
I note the audio in this case is 44,1KHz. Is iTunes unable to play 44.1 KHz audio corrrectly?
Ross.

I am still having a problem getting this issue resolved with Apple.
It's been over a week since I called. I spent 4 hours on the phone with the Apple Tech. He basically had me remove from my computer two USB port and my computer after that would not even recognized my phone. I had to do a chat for one hour with Sony and I still don't think my computer is working properly.
I am awaiting a call from Apple after their engineers figure out the problem. I had to do an iTunes diagnostic to email to them. I did the filehippo thing and that didn't work (this was suggested by the Apple tech since Apple cannot access it's old programs). I have reinstalled iTunes so many time I lost count.
I am ready to switch to a Blackberry if Apple doesn't resolve the issue this week. I can't be in a position not to sync my computer and phone too much longer.
FWIW, the Apple tech told me today that this issue is affecting 10% of all iPhone 3G users....that's a lot of frustrated users.

FCP audio sync

I have about 100 clips from a music video shoot. There are individual cuts of the track that were used during production and lip since to for different shots. About 15 tracks that were used, that together create the whole song. However, this seems like it would make things difficult in the cutting of the video.
My question is, is it possible to connect each individual clip to the original song? So that the track (~4:30 long) can sit in audio track one. And when individual clips are selected for the cutting and dragged down to this sequence. In the time line it will register whether the clip is in sync or off my however many frames.
Thank you, if anyone has heard of this being possible please let me know.

Have you tried to set this up as a multiclip project? That would seem to be the obvious way to go.

Audio Sync Problem after transitions/filters applied to timeline in FCP

I have Final Cut Pro 5.1.2 on a MAC Pro. I installed 2 Maxtor SATA II 200gig drives and created a striped RAID. I want to be clear about audio sync issues. I have my easy setup/properties....all those settings set to DV NTSC and I am monitoring out from my DV Deck via firewire, not the audio from the computer.
After capturing the clip(s) I assemble them onto the timeline, add a few transitions or filters. The audio shifts off a lot. More everytime I add or do more with the clip. After rendering more, the audio shifts more. All scratch disks, rendered clips points to the Video Drive (striped RAID) I've setup. I'm not new to video editing but new to a MAC. Yes, I am a PC guy. I work with Premiere Pro 1.5. I am pleased so far making the switch, just need to fix this audio issue.
All properties of the audio clip are correct, DV NTSC properties - 48K etc. This particular capture I made with 2 channel mono clips instead of a single DV stereo stream, simply because I have a split audio on the production tape and would like to take advantage of working with two seperate mono audio files. When I trim, I make sure the audio stays with the video but it appears that when I do trim, add a transition or filter, that's when the audio goes out of sync. No indication with a ("- #")on the icon. The clips which I captured are less than a minute long. Used for testing in these new learning stages.
Questions:
1. I created a striped RAID with the 2 Maxtor drives, I used MAC OS Extended (Journaled) with 256k Raid Block size. Is this correct?
2. Would the audio captured in 2 channel mono affect the sync? (assuming you don't shift it manually on the timeline)
3. What other MAC settings should I do to the system that will result in better preformances?
4. What settings should I set in FCP for better performance results?

hi vcp
welcome to the forum, glad you made the switch ... you won't be sorry (although you might be wondering at the moment!)
1. nothing wring with that
2. no
3. just don't install 3rd party crap you don't need ... and don't install any anti-vrus software
4. no special settings required
what camera did you capture from? did you capture with FCP?
cheers

Exported Final Cut XML from Imovie09 causes loss of Audio Sync

I have recently upgraded to ILife09 and tried a process that always worked in ILife08 but now get Audio Sync problems.
I have created an Imovie project that is 2hours and 50 mins long and wanted to export it to Final Cut Express as XML. This used to work 100% with Imovie08. However, with this latest version of Imovie, when exported to Final Cut Express, the first 45 mins of the XML movie is well out of sync (Audio / Visual).
Has anyone experienced this?

Hi Roberic,
there is a bug in iMovie '09 that causes loss of audio sync when you use custom slow/fast motion. This has been experienced by many users. See for example this thread:
http://discussions.apple.com/thread.jspa?messageID=9152271
I don't know if this applies to exports to .xml but it could well be that your problem lies here. There are some workarounds, being the easiest one to only use what the slow motion slider snaps to instead of entering custom speed percentages.

Loss of audio sync when importing Samsung Galaxy 2 (GT-I1900) video to Premier Elements 10

I am loosing audio sync when I import video from a Samsung Galaxy 2 GT-I1900 phone even when using settings chosen by Premier Elements 10.
The file plays OK in Windows 7 media player.
I have tried using both direct import from the phone and transferring the file separately without solving the problem.
The Premier Elements is version 10.0(20110902.Mol11.B123.280463)
Unlinking the audio and video makes no difference.

Letting VideoReDo simply rewrite the file resulted in loss of all but the first few seconds of audio.
Elements seems to have imported the file as NTSC-AVCHD-AVCHD LITE 720p 30fps

The computer motherboard is a Gigabyte Z68x-UD3H-B3 with an Intel Core i5-2500 CPU at 3.30GHz. Memory is 4GB.
I note that others have had similar problems with non video recorder recordings.
Can you suggest any file conversion of the original that will work – I have tried several with no improvement in the final result.
And can anyone shed light on what is the basic cause of these problems?

According to the Adobe installation information the trial version of Premiere Elements 11 is fully functional and the watermark is only present until a licence code is purchased.
I have edited AVI footage from a camcorder using the program with no problems (and no loss of audio sync) and the watermark is also present with this.
The odd placement of audio and video was caused by my not dragging the clip carefully enough.
What is odd is that the clip plays completely normally using WIndows Media Player and VLC Media player so I would expect Premiere Elements to be able to handle it without problems.
I think that there is some sort of bug in Premiere Elements' handling of mpe4 files (both in versions 10 and 11) rather than there being anything wrong with my computer.
Is there some way of communicating this directly to the Adobe programers ?
I enclose screenshots of the project settings:

Canon cameras have audio sync issue with FCP?

My mini dv deck died on me so,
I am using a small palm size Canon mini dv firewire camera to transfer about 50 tapes.
I am having a weird audio sync issue.
Sometimes the capture footage plays down in sync - I pause>scroll>play - and it's suddenly out of sync. This keeps happening. Sometimes it plays in sync. Other times it does not.
Because it's hit and miss- I'm not sure I can even re-sync.
I imagine it could be the media drive (internal)- but I have other video files on this drive that play fine.
I don't often use firewire capture.
Is audio sync a common firewire issue?
Will the quality suffer if I capture through composite/analog audio outputs?
I can patch it through my
decklink card.

Audio sync is an issue with Firewire, just not all the time. Usually it is fine, but a lot of Avid people don't like Firewire for this reason.
Most often it is a 5 frame sync issue. Slip your audio 5 frames forward and see if that solves the problem.
As well, take a look in your Browser after you capture a clip and see if the Aud Rate is either 48,000.5 Hz or 47,999 Hz. I have seen the clips come in as both of these. Once you slip the footage, export the audio only, then reimport and attach the audio to the clip in the timeline. Should take care of it.
Post back if these don't work.

Export as QuickTime Movie - lose audio sync

I have a 10 minute project that basically is a sequence of 10 nested sequences. It is an HDV project. I need to export it as a QuickTime Movie to maintain the ability to show it in HD. When I do so (using Export->QuickTime Movie - I am not using "Using QuickTime Conversion"), I maintain "Current Settings". The resulting .mov file, when played back in QuickTime Player (or anything else) has a progressively severe loss of audio sync. This is not present when playing the project within the timeline in FCP (6.0.3).
I have tried opening the project on a different computer with a virgin version of FCP 6.0.3, with the same results. I also made sure to render the individual sequences as well as the master sequence. I created a new sequence and added the individual chapters again, with the same result. I tried using the Media Manager to bring the project over to another computer - same problem. I also took this to an Apple One-to-One class with a FCP expert who couldn't figure it out either.
I could really use some help here.

First of all, thank you for responding.
I don't have a capture delay. The audio rate is 48 khz.
Interestingly, I had previously tried the separate export and stitching you suggested, but a strange thing occurred. If the resulting quicktime movie was created through a Save As... command, you wind up with a self-contained movie. When I did that, I started to get weird audio repetitions or dropouts as the movie went on. On the other hand, if I left it a reference movie, this didn't happen.
Anyway, this is a workaround, but it means that the whole thing has to be done over every time I make any change at all, and I am also concerned about getting rid of this problem for the future.
Any other thoughts?

FCE and QT PRO Analog Capture Audio sync problems

I have had major problems importing analog content into a DV quicktime movie and having the audio match.
First example: using a sony digital 8 camera with old hi-8 tapes (the camera does the analog to digital conversion) I open final cut express HD capture now or new movie recording in QT pro, and go for the whole tape or tv show. beginning is usually ok, but if i stop and start the camera, fast forward through commercials while capturing, or let the source end before i stop the capture It seems the audio becomes un-synced. usually lags by 1 sec or so, but sometimes the audio comes early by a few frames. sometimes progressivly getting worse later in the capture, sometimes the whole thing is off by the same amount. If i capture between camera starts and stops i have no problems.
Second example: using a pyro AV firewire analog converter, I get the same behavior when trying to capture in Final cut Express HD and QT pro.
My guess is that since there is no timecode on the analog source that somehow messes things up, but why do these programs shift the audio on me?

Most likely cause is your photographer changed the audio rate from 44.1k or 48k to something else.
Aside from that, no, it's highly unlikely it is the software. It's easy to blame FCP for this stuff, and we love to do it, but the capture from DV over FW is a complete clone of a digital file, nothing is being changed by FCP or QT during the process, unless your settings have been tweaked and that's a user decision.
If simply sliding the audio back into sync is not an option, dub the tapes to another DV deck via FW (producing a clone, not a generational loss) and capture form the dubs. You can experiment with a short take or two.
If the audio sync issue persists, it's the original footage, not FCP.

Problems with Audio Sync and Rendering

In both problems what happens is NOT consistent. If were, would think was a setting or something I was doing wrong.
About the rendering problem. I capture either through FCP Log and Capture or through my analog to digital "box", Formac Studio TVR. In both cases record in DV setting. When I then Import these files about 3 out of 4 times they need full rendering. But doing all things the same, there is that 1 out of 4th time where no rendering is needed at all. Does not seem to matter whether I capture through FCP or Foremac. Results seem the same. Like I said to begin with, if was consistent would figure that is just how the program is. But due to the time it takes to do a render, sure would be nice if could be avoided some way.
Regarding the Audio Sync. At times, maybe 1 out 10 times, the audio is bad. It begins at the beginning of the film being out of sync maybe two or three frames. But then every 10 minutes of film it progressively get's worse, losing a good 6 to 10 frames as one goes. I can fix by doing a lot of cutting and then moving the film around till it is in sync again, but as you can imagine takes a LOT of extra work. Any ideas as to why this is happening and what could be done to prevent in future??
Thanks in advance for any help you can provide.

I've used flip4mac for about a year and have had no problems with it. I mostly use it to export preview versions for windoze people. The quality is very good, though it takes significantly longer to export than a similar-quality quicktime movie.

Audio sync different between QuickTime and Windows Media Player

I've run into a new problem I've never encountered before. When playing a video on QuickTime on a Windows PC, the audio is in perfect sync. However, when I play the same QT video on Windows Media Player, the audio is out of sync by as much as three seconds. The Windows software is current. The source content is created using ProTools 10 on a Mac running Yosemite, from an original QT mp4 converted to a .mov via quicktime for import into ProTools. The output was a standard .mov. I also tried converting it to an mp4 via QT, but the result was the same.
This is a pretty alarming discovery as I now have to test any videos bounced from ProTools on a PC Windows Media Player to make sure someone doesn't view it this way, with the audio sync appearing incorrectly.
Anybody know why this happened? Or how to prevent it in the future?

you can buy and use the WMV Studio windows media export components from Flip4Mac which wil allow you to export to a windows media format directly from FCP and other suitable QT compliant apps ...
or you can copy the file over onto your own quicktime enabled PC and use the free, and much faster, windows media encoder there.

Having trouble with Audio Sync in FCExpress

Hello, everyone...a question for the board.
I recently acquired a new iMac with Final Cut Express...planning to try some video editing at home.
I haven't been successful with the proper configuration for captured video, however...using a Sony TRV-900 as my source, video feeding in via firewire 800 (I bought a 400/800 adapter to make it work), and ingesting using NTSC Basic...however, my audio is still not in sync with the video--the video is always ahead, and it jumps further ahead the more I ingest.
Is there some configuration I need to use so that the audio syncs correctly? Is it, as I suspect, a drop-frame issue that I haven't set up correctly?
Any help you could throw my way would be very much appreciated.

I realize that most DV cameras will record in 32 and 48 sampling rates. What I'm trying to get you to do is see what you've ALREADY recorded.
Open one of the captured clips in QuickTime, then hit Command j to see the movie properties. Or in FCP, right-click on a captured clip and choose Item Properties to see what audio you are trying to capture. Once you know that, create a Sequence with those settings, then capture any remaining footage with those settings. If needed, recapture any footage that was previously captured using the wrong settings.
