Audio sync lost when recording

I have another problem after the latest update (besides the applescript).
When recording a movie the sync between audio and picture is lost.
I use a canopus ADVC 110.
Using iMovie still maintains the video audio lock.
This update is just horrible, how could apple release this crap?

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?

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

Audio sync lost when capturing

I have recently encountered a problem while log and capturing the past two tapes. This is something that is new to me because in my previous 3+ years of using FCP I have never came across this. I am using the Sony DSR-11 and FCP 4.5 with 4 GB of Ram on a G5. I have corrected the problem within FCP by moving the video +7 frames to match up the audio, but was wondering what I can do to fix the problem while I capture. If anyone has encountered such a thing or knows the fix please let me know. I'm not sure if it's the deck, computer, or hard drives.
Thanks

One way to test is to do a capture using the camera as the tape drive.
If it syncs ok using the camera and using the DSR-11 it does not, there is something in the way the canon wrote the data that the sony is having difficulty reading.
What was the format of the recording - straight NTSC (or PAL) DV?
How are you monitoring the disfunctional sync? Are audio and video going out firewire to their respective devices or do you have video going out firewire and monitoring audio off of the computer audio out?

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 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.

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!

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.

Premiere Elements 8: Audio sync problem when exporting to Quicktime H.264

Audio tracks hissing when record enable is engaged

Hi guys. I am having a big problem with hissing when record enable is engaged. I've discovered that when I click off software monitoring the hiss goes. But then I cant add effects like reverb for singers who want to record with reverb whilst they're recording. It shouldn't be the case, but any enlightenment and I would be grateful. Thanks.

Audio gets lost when sending to Premiere Pro

Hey fellow Prelude users.
I encountered a nasty problem. I ingested some AVCHD Clips in Prelude and edited them and made many, many clips out of the footage. Then I sent it to Premiere for further edit. Unfortunatly at some Clips the audio is now missing, even if there's audio in Prelude. I tried to export just the audio from Prelude to match it with my roughcut but also the export has no audio at the points where the clips with missing audio are.
When importing the Clips without the new metadata by Prelude the audio is just fine. This seems to be a pretty weird issue.
Hope you can help.
Thank you,
Alex

I have run into the same problem with AVCHD footage. Initially, I thought that the problem might involve the transfer feature in Prelude CC's Ingest function. I had used that when ingesting the problem media, to move source clips to a couple of different folders on my edit station.
I subsequently realized that probably wasn't the case, since I had logged the clips in Prelude after they were ingested. So, they had sound when I ingested them, but not later, when I imported them into Premiere Pro CC.
The audio loss was complete on one clip--no sound at all on the clip or subclips when I opened the clip in Premiere. The audio loss was partial in the other clip--the audio level flatlined about three-quarters of the way through the clip. Each clip was about twenty minutes long--an interview with a subject for a documentary I'm shooting. I set subclips for each response that I planned to use in my cut of the film.
I keep my source cards as backup, so I was able to go back and re-ingest, this time without using the transfer feature. Instead, I copied the source card to my edit station, using Windows Explorer. Then I used Prelude ti ingest and log the copied media. That appears to have imported into Premiere without problem.

Audio sync issue -- sound recorded at 44.1khz image sound at 48khz

hey team:
so I recorded a music session the other night with 2 canon 60Ds, which recorded the audio at 48khz. I recorded the audio separately to a computer running Ableton Live, which has recorded the tracks at 44.1khz.
I used PluralEyes to sync the footage and audio. All's well syncing the footage, but the audio, being a different frequency, drifts from sync.
I've searched a lot of internet archives on this matter, but none of them seem to work. I've used Compressor to resample to 48, but it still drifts. I've used Soundtrack Pro to resample, but it still drifts. I've gone back to Ableton LIve and re-exported at 48, but it still drifts.
I've even taken my 48khz resampled file and retimed it using markers at the beginning and end of a long clip. The weird thing is that it syncs at the beginning, is out in the middle and syncs again at the end. I'm assuming this is because the sound wave of 44.1khz is slightly elongated compared to 48khz, so they will sync at points but not throughout.
Have already lost about 8 hours to this nonsense.
Does anyone have a solution?

Hi Gary Can you explain how it solved your problem?
I also tried exporting using qtpro and the problem persisted -- synced at the start, synced at the end, unsynced in the middle....
cheers

System Overload/Core Audio Error Message when recording/playback

Well ive been experience this problem for a while now but ive read up on it and done some troubleshooting and think i may have found a solution.
Well what happens is ill be recording say one track or 2 tracks in mono or stereo or playing back about 3 or 4 tracks and logic will stop everything and give me an error message which either says system overload or core audio overload or something. Well i figured i was overloading my cpu so what i tried doing was restarting my computer and then only operating logic as the only program. this worked temporarily sometimes but not in the long run. well i did research and came to this.
apparently its too overbearing for my Powerbook processor to record in 24 bit/96 Khz which is kind of a bummer because it was one of my attractions to my i/o box that i could do that. also freezing tracks will help greatly apparently which i have yet to try but hope will work too.
also i recently deleted about half of the stuff on my internal drive and put my 42.41 GB of music onto my external HD so now i have 54.6 GB on my internal HD which holds about 93 GB total. should this help me greatly? or will it only be a minute difference?
well any more solutions/suggestions as to what i can do to better my situation? also am i correct as to why i think i get those error messages.
ps: sorry for the uncapitalization, i got a bit lazy here
thanks
-Mike

Mike,
Bit depth is more important for recording quality than huge sample rates. If you're going to change your settings, I'd stick with 24 bit, but reduce sample rate to 48 kHz.
When you say you've put all your music on the external drive, what exactly do you mean--your Logic files or your mp3/AAC files? Normally you would want to use an external drive to record onto from Logic. That way your internal HD can run the OS and Logic, while the external is free for all the fast recording tasks. (This assumes your external HD is pretty fast, and ideally is firewire.)
Freezing works wonders, too, if you're processing tracks.

Audio sync problem when exporting between FCP6 and Soundtrack

Hi, I'm a newbie to this so apologies for any glaring errors.
I've recently upgraded to FC studio 2 and have exported the audio of an existing 20 minute custom format quicktime project (720x408, 30fps,) to soundtrack for sweetening.
Trouble is, when returning the audio back to FCP, the audio is shorter by several seconds and therefor totally out of sync! I've also tried outputting the multitrack audio from within FCP and bringing it back in as a single file and this is also out by several seconds. The output settings are the same as the project.
If I do nothing to the audio and simply send it to compressor; the M2v and it's aiff play in sync in Quicktime.
Any ideas or work arounds?
Thanks in advance for any advice.

Audio sync lost from AE to Encore.

I'm using AE6 with a 23.976 timeline with audio that is correctly synced in the timeline. I render using the Blueray presets and import the resulting audio and video files into encore dropping them into a new timeline. This is a full feature length film. The audio begins to drift in Encore the further down the timeline unlike in AE. Sync is lost. Anyone experience this? I'm using adobe's own presets.... The platform doesn't seem to make a difference. Madening trying to get a bluray out the door. Alternatively, one could render the AE project in media encoder, but I don't see that being any different.
Thanks!
Similar bug found in that h264 files rendered in AE at 23.976 do not have their time interpreted the same as they go to other apps like Davinci Resolve.

> Alternatively, one could render the AE project in media encoder, but I don't see that being any different.
Actually, it's a lot different.
The MPEG-2 and H.264 exporters in After Effects have a lot of problems that the corresponding formats in Adobe Media Encoder (AME) don't have. Whenever possible, use AME for exporting these formats.
What I do is export a lossless master/archive file out of After Effects and drop that into a watch folder for AME for all of my distribution formats.
