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.

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 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

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.

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.

FCP Sound Syncing Question

Hey Everyone,
I have an audio syncing question for you. Any help would be greatly appreciated!
I am cutting in FCP. I logged and captured my footage and with timecode breaks, etc. the tape was cut up, and I was left with eight files, let's call them Footage1-Footage8. I have completed my cut of the piece using the in-camera audio that was linked to the video on the DV tape that I imported. Our sound guy in the field used a DAT recorder to record the production audio and apparently captured the timecode to the audio files, so that it matches the video (i.e. the DAT recorder and our cameras - DVX-100s had synced timecode during the shoot). The DVD he gave me has 20 audio files as .wav, let's call them Audio1-Audio20. My question is, now that I have finished my cut, I would like to replace the current audio tracks with the production audio. How can I sync the audio with the video and replace it in what I've cut. Or perhaps I can't, in which case - how can I sync them up and THEN cut, but I'd really rather have to not do that, lol!
Thanks for your advice!

Sorry about the long winded post, though.
I guess my real question, summarized is - is there a way to sync separately recorded production audio (that has timecode) with the footage that I shot (that has the same timecode as the audio, but also has in camera audio that accompanies the video track - I would imagine I can just "cut" the extra audio tracks, however).
I'm at my bay trying to figure this out, and I've got nothing, and the people I work for don't want to spring for that bwf2xml program you were talking about What's the emote for pulling one's hair out?

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?

Panasonic DVX-100 audio sync tool not showing up in the tools menu

Using FCP 7 in new Mac Pro with a clean install. I following the directions for copying the DVX-100 audio sync file into the proper folder /Library/Application Support/Final Cut Pro System Support/Plugins/
The directions say the Offset Audio Sync command should now appear in the Tools menu. It does not.
I have tried trashing preferences - reinstall the Audio Sync Tool - but it still does not show up.
I use the Panasonic Camera and with my earlier editions of FCP I had no problem installing and using
the Audio Sync file.
Anyone have the same problem or know a solution?
Thanks

I am not sure what's happening with IE9 (no live site) but I had real problems viewing your code in Live View - until I removed the HTML comment marked below. Basically your site was viewable in Design View but as soon a I hit Live view, it disappeared - much like IE9. See if removing the comment solves your issue.

Audio sync drift after "live" CD import and convert to 48/16

I shot DV footage on a PD150 cam. The band recorded a CD from sound board to replace the mic audio of the camera. I'm running Final Cut Pro 3, and I have already converted through Quicktime the CD tracks to aiff files running at 48 ( they were 44.1) and 16 bit. The DV cam Orignal audio was also recorded at 48/16. Now when I try to sync the Cd audio (48/16) to the video clips 1: the audio sync drifts off during the song, and though it started right, the whole sync is way off by end. 2: The audio file in the track bar is longer than the video clip in the track bar above. huh? Could it be data rate Audio 187kbps vs. Video 188kbps or should I try and slow/speed up the play rate of either vid or audio. Or is this an impossible meshing of media?
G4 Mac OS X (10.4.8)

As Jim says, it's a function of how this was done. Next time you will know to look for ways to avoid the issue. But all is not lost.
I'll give you the skeleton and you can figure it out.
Find exact sync points near the beginning and end of the "video audio" and the "CD audio". Use drum beats you can be sure are the same. Identify them by ear and then by their waveforms, and put clip (not timeline) markers at those points.
Sync up the ones near the beginning exactly. Now go to the other two, find out how far apart they are, and write it down. How? I haven't got all day.
Calculate the time between the 2 markers in the video clips's audio, and between the markers in the CD audio.
Translate both of those numbers into frames.
Calculate the percentage by which the audio is longer CD audio / video audio = X%.
Go into Soundtrack Pro or audio app of your choice and make a version of the CD audio that is sped up by X%.
Bring that back to FCP and replace the version on the timeline with it.
If the markers didn't survive, find the sync points in the new CD version. Line up at the beginning. If the ones near the end now match, everything is done and you can call me "Helpful" and "Solved". If not you can be angry at me or read it again.
Good luck!

HDV imovie projects lose audio sync when burned in idvd

I have 80 min. HDV projects from imovie sent to iDVD, after burning them onto dvd they play fine then lose audio sync after about 60 min. or so.....

Painful in iDvd to do interviews when they happen to fall over the 60 minute mark, isn't it?
If it's of any consolation, it's more reliable in Apple's FCS2 / FCP => DVDSP.
Toast might be another option worth looking at....
Good luck on this.

Strange Flash Audio Sync Issue

This is by far the strangest problem I have come upon and
can't find anything in any forum discussing it. My site is
www.aloversscent.com. We are trying to put up 4 videos. I am
editing in FCP and compressing in Compressor to H.264 and then
making the files flv files to bring directly into Flash. All of
them are working fine except for our third episode, Operation Fox
Hunt. The audio sync is going off when the title cards come up,
about a 1/3 of the way through the video and only then. I went back
and made new exports where I tried filling in the blank audio
pieces under the cards with Slugs, I tried creating the title in
LiveType and then transfering it over instead of using the FCP
title cards. But neither worked. The strange thing is they work
fine when I play them in Quicktime. It's only when they play in
Flash that they get out of sync. If you scrub through the timeline
they will sometimes match back up again but while playing they
always get out of sync. I have run out of answers and need help
bad. Please let me know if you have any ideas.

Are the audio files being brought into Flash as FLV?
The only audio sync solution I have found is to set the MP3
compression to
anything higher than the default of 16kbps (Publish
Settings).
