Audio sync out when reconnecting media

Hey if anybody could help it'd be so appreciated.
Editing a short film. Myself and editor have same specifications on os x, and same update of final cut (6.0.6). Got the project and files on a hard drive from him, a duplicate of the file he works from, but when I open project file and reconnect media, the audio is COMPLETELY out of sync on every take. It means I can't work on it at home and bring it to him for detailed work, basically, no going back and forth..
When reconnecting the "file attribute mismatch" thing comes up, and the attributes differ as follows; 'media start and end', and 'rate'. I presume this is the explanation, but what's the solution?
Is there something obvious I'm missing, some easy fix? OR even a longer, harder one that will mean we can go back and forth?

Oh God, I might be in over my head already...
Thanks for the quick reply, I'll see what I can find, not sure where to find all that information exactly but I'll give it a shot. This forum is amazing, thanks.

Lip sync out when ps4 played thru 43w755c

Lip sync out when playing ps4 thru kdl 43w755c. Please help

Try the following ...
Exporting from imovie to a movie file - you have the option of with quicktime or without it - not sure which works best - try both.
Do not share it directly with idvd - it can take a few hours to make the movie or MP4 file.
Then open idvd and import the movie into idvd.
Add your titles and burn your DVD as a disc image - this can also tkae a few hours.

Why does audio drop out when scrubbing iMovie events?

Why. does audio drop out when scrubbing iMovie events?

If the audio returns if you slow down scrubbing you are probably just scrubbing too quickly.

Audio Sync Issue When Exporting to Quicktime

Currently using Premiere Pro CS3 3.2 and Quicktime 7.5.5
When I export to a quicktime .mov, my audio is a few frames out of sync. I've tried downgrading to older versions of quicktime with no success. Everything is completely in sync inside Premiere. If I import my rendered out-of-sync .mov back into Premiere, it magically syncs up fine again. It's the weirdest thing.
Help!

Scott:
There is a workaround.
I never really found a solid cause/solution, but if you're noticing that you have a couple of white frames at the end of your Quicktime exports, then you're probably suffering the same problem I have. Tech people I have checked with have suggested that the problem may be related to the use of .mp3 sound files (as opposed to .wav) in the Premiere project, but after removing them and replacing them with .wav's the problem persisted.
I am not technical enough to figure out exactly what's causing the problem, but I think it must have something to do with the Adobe Media Encoder (at least how it works on my computer). From what I've read on the subject, the Media Encoder is Premiere's Achilles's Heel.
Changing versions of Quicktime did nothing. Others trying to solve this problem have tried exporting their files with every conceivable variation of options and settings in the Adobe Media Encoder with no positive result.
I'm not the only one with this issue, but searches of the Internet show it to be relatively rare, so it's probably some weird glitch somewhere deep in my system. It's not widely-reported enough for anyone to care about addressing this bug. Of the few people that I've found suffering from this anomaly, none have found a fix.
But the good news is that I have found a workaround that accomplishes getting a quicktime file out properly that does work for me. I avoid the Adobe Media Encoder completely.
Step 1: Go to File > Export > Movie, and under Settings > General choose QuickTime, under Video > Compressor choose H.264, then Uncompressed Audio. I have not experimented with other settings, but believe that most of them will do just fine.
If you examine the quicktime file you've just exported, you'll see it works just swell; i.e. no white frames at the end of the movie and the sound syncs up perfectly. Okay, sounds great---but there's no way to limit the data rate using this method, which means we're stuck with a ridiculously large file.
The solution is to load the Quicktime file that you've just exported into Quicktime Pro, and now export it using data rate compression / sound compression options to suit your tastes. Bingo!
The other workaround that I have heard from some is to export your movie (again, avoiding the Adobe Media Encoder, instead using File > Export > Movie) as an Uncompressed AVI, and then compress with QT pro as before. This method didn't work for me, something about not having the proper codec on my system to read the AVI file that was exported, which makes absolutely zero sense but I couldn't find the right codec anywhere, even after identifying it with some super-duper codec identification utility. Go figure!
So, you'll have to get QT Pro ($30 I think) to use this workaround, but it does work, and that's what counts. I have no idea if there's a QT Pro clone or similar program available out there. Compression/decompression and all that jazz is way beyond me and I'm just happy to be able to get my file finally out there in working condition.
The only other bit of information I might share with you is that I tried searching the Internet at great length to try and solve this issue, but on the rare occasion I did find someone suffering this problem they were as confounded and frustrated as I was, and no one had a real solution. I continued to search with different search terms and tripped over the clues to this solution when searching for "white frame problem" in relation to Premiere. I even believe that if you search the Abobe forums you may find some posts about it, so if you're inclined to learn more about it, I suggest concentrating your searches with terms that refer to the white frame problem/issue, instead of the terms I used for so long, such as "Premiere Audio Sync Quicktime" and the endless permutations thereof.
But I'll bet this workaround works for you. Let me know, and if you'd like me to try it on one of your exports on my computer I'd be happy to give it a go.
I have often wondered if upgrading to CS4 would solve this problem. Are you using CS3 like me? If I could be sure CS4 made this issue vanish I would jump on it, but there just isn't enough information out there to know for sure. I'm inclined to think not.
Please do let me know if this solution works for you, or if you dig up any new information.
Thanks!

Problems importing iPhone 4 video into After Effects CS5 - Audio sync out

Hi there,
I am currently experiencing problems trying to import iPhone 4 video into After Effects CS5.
Firstly i'd like to note that the video plays perfectly fine on the iPhone, VLC and in Quicktime Player. The audio and video is in sync.
When I add the footage to After Effects the video becomes slightly out of sync with the audio. I have noticed this in RAM preview and also in renders I did just to test.
I also want to note that, both my iPhone and After Effects have latest software updates.
Thanks for your help

Thanks Rick and Mylenium
Thanks that worked!
I thought that changing the frame rate in the composition settings would have worked.
Instead what I should have done is to go the the footage in the Project Panel then right-click on the footage > Interpret Footage > Main... then Conform to frame rate: Frame rate: 23.986607 (or whatever more accurate frame rate your footage actually is)
I used the more accurate frame rate reading from VLC which went to 5 decimal places. I got that info from the top menu in Tools > Codec Information
Its a shame AE doesn't pick up on the more accurate fps. It seems that all the videos from my iPhone 4 have slightly different frame rates and I guess I will have to interpret each clip properly.
I hear that the frame rate on the iPhone 4 is different depending on the lighting? I wonder why that would be the case?
Hope this helps anybody else that might face this problem.
Cheers

Audio sync issue when exporting to h.264

I've seen this issue reported many times, but can't find an answer, or whether it's simply another bug in Premiere CS5. The same issue happens on more than one computer (PC with Intel i7, 64 bit, GeForce GTX 470, and BlackMagic video card), the video is HDV using Sony Compact flash. Audio sync is fine throughout editing and exporting to standard DVD or h.264 blu-ray using Encore Dynamic link. But when I export directly from premiere to create a flash video or h.264 720p video, the audio moves ahead of the video by about 4 frames. This didn't happen with CS4. There is a similar issue if I export using MPEG2, though the audio error seems less consistent. Have wasted very many hours, and a fix or solution would be welcome! Many thanks.

Having the same issue here. Some kind of solution would make me so happy right now.
I've shot and edited a series of short interviews on a DSLR. So I've started with H.264 files and I'm attempting to export the final product to h.264 and the audio is very noticeably out of sync.
The only workaround I've come up with so far is as follows:
1. Export the audio only from the original sequence
2. Export the video only from the original sequence
3, Start a new sequence and drop in the files I just created.
When I export that sequence, for some reason, it syncs perfectly. Needless to say however, this is a huge inconvenience and time waster, especially when it comes to making further edits.

IPad 3 audio sync issue when video imported into CS5.5

Hi everyone, long time lurker here, love the support you guys are giving!
I'm hoping you'll be able to help with an audio sync problem I'm experiencing with videos recorded with the latest iPad 3 (well, that's what I'm calling it anyway).
I believe the iPad 3 recording format is 1080/30p with 44.1Khz / 16 bit audio, but when I match those settings on a Premiere Pro CS5.5 project (or try 48KHz audio as a test), the audio gradually goes out of sync. If the video is several minutes long, it becomes quite obvious, and by 10 minutes, it's terrible!
I should add the file plays back fine on the iPad itself and was imported to a Mac via iTunes. It also plays fine on the Mac itself in Quicktime.
Does anyone have any suggestions on project settings that'd work?
On a related note, I additionally captured the audio using a Zoom H2n which i intended to replace in Premiere, but foolishly I captured it at 48KHz, rather than the 44.1KHz of the iPad video file. Should I resample it?
I actually managed to line-up the 48 and 44.1KHz waveforms from the iPad and Zoom in Premiere quite accurately, but again both gradually go out of sync with the video...
I'm running Premiere Pro 5.5.2 on Mac OSX 10.7.3.
Any suggestions greatly appreciated!
Gordon Laing

To update my original post, I have found this problem happens about half the time.
Sometimes there's no issue and the audio is in sync when imported into Premiere, but at other times it's way off.
I did however find a workaround which has resolved the problem on my iPad3 videos which were out of sync and that was to first import the video clip into iMovie on the Mac first, then simply export it again using the 1080p option. The subsequent file is much larger (so there's been an annoying re-encode), but when imported into Premiere, the audio is at least now in sync.
I used this to fix the audio on a couple of the videos you can find on this page (all of which apart from the last one were filmed on the iPad3)
http://www.cameralabs.com/features/Working_holiday/
Since the video wasn't exactly critical to start with, I'm not too bothered by the re-encode.
Let me know if this fix works for anyone, and also if anyone comes up with a different solution.
Thanks,
Gordon

Audio sync drifting when recording

Hi everyone,
Has anyone experienced something like this?
I'm recording a webcam. A Polycom CX5000. I have it set to record the encoded video and audio with a limit of 30 minutes (creates a new file). While doing the encoding, I get no notification of any dropped frames, yet when I play back the resulting .FLV file, the audio drifts out of sync in the first file after about three minutes. When the recording went over 30 minutes, FMLE started a second file and for some reason, the sync pops back on. Is there a bug in FMLE or some setting I can do to avoid this?   I'm encoding on an i7 PC so I don't think it is a hardware issue. For encoding I was using 15fps, 640x480 and audio at mp3 224.
Thank you,
Mark

Hi,
Thanks for your response.
>1. Does the sync problem aggravates over time or does it remain constant from 3rd min to 30th min?
It aggrevated over time. You can't really notice it until around 3 minutes into the video. I watched it again and it looks like it the sync fluctuates slightly. Goes out of sync, gets back in sync (or nearly) and then goes out again.   Listening on headphones I hear tiny, split second drops outs or glitches (related?).
>2. Did you observe the sync problem in the live stream also?
This time didn't even do a live stream. Had similar issue two weeks ago that was live stream and file save. Assumed the issue was due to network issues.
>3. Can you reduce the file split time to let's say 5 min and reproduce the problem again?
Will be trying this today or tomorrow.
>4. Which audio device are you using? Is the audio and video device coming from the same device?
It is from the same device (I think.) I am remotely troubleshooting for someone so I'm not 100%. It's a Polycom CX5000. The first one we have. We previously had a Microsoft Roundtable which is the same device. The device names come up differently though so that's why I'm not positive. The Video device is currently listed as Integrated Webcam (which must be correct as I'm getting the right picture). The audio though lists "Microphone Array (IDT High Def..." something..    That might be the laptop's built in microphone? If so, that might be the issue.
>5. If you have a different audio-video devices, please try with them and come back with the result.
Will let you know.
I'm hoping it is #4 as that would be an easy fix. I would find it hard to believe Adobe released a product that couldn't keep audio and video in sync, right?

Quicktime TOAST VIDEO CD export, mpg files, audio sync out

I used the TOAST VIDEO CD option from my FINAL CUT PRO 3.0 version to make mpg videos to upload to my website, so it seems to be the easiest format where a PC platform and MAC platform can both run this file...
well lately, i can't remember what i've changed, if anything, but the files that I export, become out of (audio) sync when they become mpgs. However, I can do mp4 and its fine, or any other format. But when I do video toast cd (.mpg), and I play the file on the laptop, its audio is out of sync. I am running QT 7.0.1 downgraded from 7.0.4, that i was using earlier... with Final Cut Pro 3.0, and running Mac OSX 10.3.9
please someone help me with this, its driving me nutso!
please

It sounds (no pun intended) like a Toast problem.
QuickTime doesn't export to MPEG-1 or 2 formats and it isn't involved with the conversion. Maybe you can find an answer in a Toast user forum (if any).
I've never had any issues using the steps you use but my conversions were from original QT formats (not .avi) and the files were under 5 minutes.

HELP! Audio Drops Out When Trying to Capture Canon XL2 Footage

Please help me out here. I'm a freelance camera operator w/ a Canon XL2 and several times now I've gotten calls from the editors saying they're having problems logging my footage, mainly the audio drops out quite a bit, and I'm not talking bout one second for every 2 or 3 minutes. No. It's like every 10 seconds the audio drops in and out.
What's the deal? Two times the guy was using a Panasonic DVX-100A to capture, another time it was a SONY DSR mini-DV deck. With each incident I had to go over with my XL2 and use it as the capture device, which is a pain.
The program they're using is FCP HD or 5. But I think even when they just play the tape in their Sony or Pany cameras, the audio may still suck.
Help me out here, I can't be the only one with this problem.
Thanks.

Well Robert Swanson, I hope my post wasn't taken offensively, it certainly wasn't meant as such. The only Canon camcorder I owned was the GL1. After switching to Sony's I can honestly say it would take something significant to go back. And, I was merely relating my experiences in trying to capture from other Canon camcorders so that I know where you are coming from. However, I am interested in the HVX being the "noisest" camera on the market. I am seriously considering this camera and would be interested in a review that points this out. I would be using the hard drive recorder instead of P2 cards.

Audio drops out when following video to external monitor

When I play a sequence to an external monitor, the audio drops out for 2 to 3 seconds after changes on the video track, and then pops back in with no interuption in video output. It doesn't happen at every cut, but it's consistent in the places it does. I thought it might be caused by the size the project has become. So I exported the sequence as a quicktime file, closed the lage project, opened a new one and exported the new file and played it and it happened again, even though there were no edits. It doesn't occur at all when I turn off external video, and play it on the computer. I connected a new firewire from the computer to my DV deck, restarted the computer, but it keeps happening.
Is it that the dramatic change in color, light and compostion crowding out the audios ability to follow the video through the wire?
I'm completely stumped. The next step will be to open the computer and try to blow any excess dust out. I do this periodically anyway, and my last time was two months ago, so I'd be surprised if it works.
Maybe the G4 with 2G processing power can no longer handle the program, but it shows no sign of stuggle in any other way.
My clients are starting to grow restless.

Thank you so much X & Paul, for your suggestions. Although they didn't solve the problem, they kept me hopeful enough to continue my quest for an answer. After exhausting all effort to find the problem in the audio, I decided to focus on the video. So, I tried correcting the excess luma on the consolidated QT movie, and suddenly the problem was fixed. Because of the different levels of correction I'd need for each and every cut in the original sequence, and the precious time it would take, I'd planned to save it for the color correction stage, a mere 2 weeks away. I remembered how illegal white would often cause the image on some monitors, specifically consumer TVs, to waver for a second. But this was happening all the way back to the DV deck's audio meter, so I never expected it to be a luma issue.
I assume that the outdating capacity of my G4 played a part, but I wanted to write back with my thanks, and to impart my illuminated wisdom to the next perplexed soul.
Thanks again,
jesterhead

Audio Sync Problem When Playing on iPod

I just got my video iPod and have been encoding some .avi's using Xilisoft. When I play the output as a .mp4 it's fine on my laptop, but when I play them on my iPod there's a distinct audio sync lapse that gets worse as the players goes. Many videos also freeze at 1:51 (even though the time indicator shows the whole file time).
Anyone else having this problem and found any solutions?
Thanks.

Messing up when reconnect media

Dear All,
I always use reconnect media function, as we have 2-3 editors working at the same time on different machine and even locations. Everything goes well until connecting STP files.
Now we are close to the end of the project and have been sending sound files to STP for sweetening. The problems is when we reconnect those STP files on another machine (of course, we copied all the media files to another machine as well), FCP connects to wrong files and has different sound from another take.
What's wrong? Please help.
Thanks.

Joanne,
I believe you are still under warranty. I recommend backing up your data and taking your iBook in to be looked at. Your logic board might be failing.

Audio cuts out when using Interfaces

Just recently bought my first iMac, with plans to use it for multi-track recording. The audio is cutting out when using FireWire or USB interfaces to record and/or play audio. For instance, with an Edirol FA-66, even iTunes experiences brief periodic audio loss (every 20 seconds or so) when playing through the device. PreSonus Firebox works a bit better, with a 1 to 3 second loss every 40 seconds or so... this happens when using OSX as well as XP... the operating system doesn't seem to influence the problem. To be certain it wasn't a FireWire issue, I tested it with an M-Audio USB interface and had the same audio loss.
Talking with tech support, the first guy just blamed everything on the 3rd party devices. That drove me CRAZY. Finally he got a specialist on the phone, who blamed it on the intel chip.
Right now I'm just living with it... trying to record songs in smaller pieces. I wait for the audio to drop, then as soon as it comes back I hit record. I've got about 40 seconds (using the Firebox) which is enough to lay down a verse or chorus.
I'm just hoping, HOPING that someone at Apple is looking into these things.

Hello,
This may be a stretch but your mention of " hard drive hanging" prompted me to suggest your problem may involve low data transfer rates. (I mean, the hard drive may have too slow.)
When, for example, Final Cut Express or Pro are being used, they require high data transfer rates to avoid frame dropping. Apple's article on the HD requirements for those apps is here:
