Audio out of sync AFTER importing

Oct 18, 2012 8:55 AM

Tags: #adobe #after #out #audio #premiere #bug #of #sync #importing #normal #before

Hello, how are you?

 

I've been searching for a solution for a while, but I can't seen to find any.

 

The thing is... I've been capturing some gameplay footage, with files that last an hour or even more.

When I watch the files in any player (Windows Media Player, VLC, Media Player Classic) they play fine, the audio and the video seems to be on sync and OK.

But after I import to Adobe Premiere, it just gets out of sync. Even when I watch in the Source Monitor, before dragging to the timeline.

It looks like there is a problem when conforming the audio.

But even the time duration is different from the original, there is some frames or even seconds of difference inside Premiere.

And this happens with different codecs, AVI (from FRAPS), H.264 (with AAC audio and MP3)...

 

I've tried cleaning the cache, deleting the software and reinstalling again, converting - everything.

 

Some are saying this is a recurrent bug on Adobe Premiere. Isn't there any fix or something that I could do?

 

It's really strange that the problems only occur AFTER importing. Outside of Premiere is fine, so there is no problem with the capture, right?

 

I would really appreciate if someone helps me. Thanks a lot!

 

 

PS: I have Adobe Premiere Pro CS6.

Intel Core i7

12 GB RAM

GeForce GTX 580

HD 2 TB 7200RPM

    I have the exact same problem. I have some .mp4 files I recorded on my phone. Works fine everywhere, as soon as I import it into PP, the audio is out of sync. I believe it is due to the fact that the video has a variable number of frames per second. I don't really know how to fix it so any help is greatly appreciated.

    I'm having the exact same problem in CS5.5, and from my searching it is a fairly common problem with no solution.

     

    However it is hit and miss. The H.264 MP4 files generated from our Tricaster 855 will sometimes playback in Premiere with no problems. But occassionally one file will have this sync issue, with audio about 8 frames ahead of video.  The file will, however, playback just fine in Quicktime, Windows Media Player, VLC, etc.  It's only when the file is imported to Premiere that it plays back out of sync.

    Same problem here in Holland..

    Capturing DV-footage from PanasonicNV-GS400 always without any problems but....

    Same .avi files which were perfect in sync (old backups) are now out of sync after import in Premiere Pro5.5 on the time line.

    Starting IN-sync, it gets worse and worse and after 30 minutes of footage, the audio is one second 'too soon'..

    This thread does not cover the basic aspect that the by PP5.5 captured DV-tape is IN-Sync at the beginning of the timeline but OUT-Sync at the end of the timeline.

    Complete rendering (changing red bar -below timeline time code marking- into green) does not have any effect.

    So- because I need to finish the project, I unlinked Video/Audio, changed the audio speed from 100% into 99,98% to get both perfect in Sync (at another sequence I needed to change to 99,99%).

    After that I could get the video's in sync on DVD (dynamic link-Encore)

    Anyway, this is really bad!

    A simpel footage (25 frames footage and sequence settings) imported bu PP5.5 from DV-tape  may never be out of sync and in all the years I work with Premiere I did not notice this effect.

    Please go back and re-read the header in my message #6

     

    My reply was to the person in message #3, concerning video from a cell phone

     

    For that person, the link I posted DOES cover the problem of cell phone variable frame rate video

    I've been having this same issue, I too was trying to edit together footage that I've recorded from games last night when I ran into this issue.

     

    I did some searching this morning and came accross this: http://blog.flickharrison.com/2012/04/problem-solving-in-adobe-premier e-audio-glitches-and-sync

     

    Not sure if you've looked at that already.

     

    I'm at work at the moment so can't test it out, I'll be having a go this evening when I get home. Until then though - has anyone tried this and does it work?

     

    Cheers.

    XMP files you get after converting to i.e. M2V format (mpg) by Premiere pro (media encoder)

    I have the sync problem BEFORE that, in the basic .AVI file (DV-format video and audio directly captured from DV-tape!!!!).

    The file is is not compressed, None HD (standard wide screen) 45 minutes appr. 13 GB.

    This file is in sync in ANY player (from media player till VLC media player).

    So the file is in sync anywhere but in Premiere Pro 5.5 timeline (being captured by premiere for crying out loud!) so will remain out of sync when exporting to other formats.

    As mentioned before I did a workaround by reducing the audiospeed to 99,98% but that cannot be a 'permanent' solution..

    Anybody found the real cause of out of sync?

    The audio/video sync problem seems quit widespread and on different versions of Premier Pro. I still can't find a solution. Post 6 and 9 didn't work for me.

     

    The audio/video are in sync on VLC, Media Player etc -- the problem only exists when importing into Premier Pro CS6. It is taking ages to re-align the video/audio in PPro which is not a solution.

    I am having this EXACT same issue.

     

    I have some video that I recorded, and in every other program besides Premiere Pro (I've tried both CS 5.5 and CS 6) it plays with the audio and video in sync. It isn't as simple as Unlinking the audio and dragging it to match it up, no, it's as if the audio slows down over the progression of the video. So even if I were to drag the audio and sync it up to someone talking (which is such a pain...) immediately afterwards, the audio will gradually become out of sync again. And if you try to line it up again, then the whole project gets screwed up. Extremely agitating. I've attempted to slow the audio duration down as others have posted before, but that doesn't work right. I had to slow it down to (98.5% before SOME of it was synced and it had incorrect pitch) Just awful. I have over 120 videos that need editing and I'm not going to be using Premiere Pro with this horrible audio sync.

     

    And again, in other programs like VLC, QuickTime, Windows Media Player... the video and audio are synced up PERFECTLY. Once it's imported into Premiere Pro, something strange happens to it and makes it impossible to edit comfortably.

    Is this camera generated media using a format that PP supports?

    EDIT: I tried Premiere Pro CC and I'm getting the same issue still. I also discovered something rather peculiar, I exported the audio only from the imported video, then I deleted the original audio, when I reimported the audio, it was almost 25% longer than the video! I also checked the original footage and it has a frame rate of 28.38 (some of the other footage has other weird frame rates) could this have anything to do with it?

     

    I am using an analog to digital video recorder. I am converting old VHS tapes into a digital format, they are encoded as .mp4. Premiere Pro will open the files and have the audio as well, but they are not synced, and no matter how many times I try to sync the audio to the video, it still becomes out of sync. Every other program besides Premiere Pro has the audio and video in perfect sync.

    Everybody, I found a workaround for this bug!

    You have to use another editing software such as the free windows live movie maker in order to cut any footage that is longer than about 5 minutes into smaller chunks (no more than 5 minutes long). Have each chunk saved as a separate video and then import them into premier pro separately. That way premier pro does not have enough time to de-synch the audio for each chunk.

    It' sucks that you have to do this extra step but at least you can get on with editing using this software again.

    That is most likely your problem.  Use a hardware/software combination that will record your tapes to DV format.  Something like the ADVC110 from Grass Valley.

    Hey I don't know if you've found an answer to your problem from someone else yet, but I have had the same problem before, and I've finally found a fix that I'd like to share.

     

    For my problem, it was my webcam's visual that was getting out of sync of my webcam's audio on top of my gameplay footage. Now I'm not a computer genius at all, but I found out that recording devices can record in "variable framerate" or "constant framerate". If a vid is getting out of sync with itself while in Adobe Premiere but not out of sync when you watch it outside of Adobe Premiere, it is because it was recorded in "variable framerate". What variable framerate means is that it cycles/changes the frames at different speeds throughout the video, making the video a different length while in Adobe Premiere than the original video outside of Adobe Premiere.

     

    I downloaded a video converter called Handbrake. In Handbrake I just imported the video I wanted converted and changed an option from "variable framerate" to "constant framerate". After my webcam footage was converted into "constant framerate", I imported the new webcam footage into Adobe Premiere and everything was in sync at last!

     

    I hope this helps anyone who has had the same problem.

    My solution that worked was to, on my iphone 4s, import the footage into imovie then export it to back onto the phone photo library. Then I plugged the phone into my PC and imported it into Premiere and it worked! The frame rate was constant, the audio was in synch. The quicktime solution above doesn't work for me as you new to pay for a fancy version of quicktime on the pc to do that. I have a MacBook with the latest operating system but i want to keep that for music production in logic.
