Audio is/goes out of sync

Hi guys,
Brand new user to Premiere Pro CS 5.5
I took some clips off my Galaxy Nexus that I shot the other day and wanted to cut them into a short video so I imported them into Premiere.
When I play them in Premiere the audio appears to be in sync at the very beginning of the video but as it progresses through it seems to be worse and worse out of sync as it goes along. Even in a short 1 minute clip.
When I play these raw video files in something like XBMC or the standard Windows 8 media player, or even just on my phone there don't see to be any problems with the audio/video being out of sync what so ever.
I tested this out with several random clips recorded on my phone and it seems ALL of them are doing this in Premiere no matter the duration of the video.
Why is this happening and how do I prevent/correct it?
Thank you

Linked video audio clip goes out of sync when put in timeline - why?

Learning to use Final Cut Express. Clip plays in browser with audio in time with video but as soon as clip is dragged onto timeline the audio goes out of sync. Why? Please can anyone help because its driving me mad!

You don't give any details as to FCE's settings, camera format or your workflow so I can only hazard a guess.
One of the main reasons that audio goes out of sync is because the Easy Setup audio settings do not match the camera's audio settings.
The default setting is for 16bit (48KHz) but your camera may be shooting 12bit (32KHz audio).
If this is the case you need to recapture using the 32KHz Easy Setup.

Audio slowly goes out of sync over time

My capture segments are only 10-15 minutes long. However, my audio drifts out of sync and is severe at approx. 3 minutes with no dropped frames.

hi
i have exactly the same problem...
Im in really trouble with a project. I am producing a fitness dvd and the soundtrack is eating up frames in common to my video, where i try to syncronize the sound from. Its totally strange for me and i have no solution and answer why this is happening.And worst of all: no solution. The customer which - of course - is not satisfied.
I have NO clue what to do. Can anyone help?
the footage is taken from Sony HVR-V1E in HDV and the soundtrack is taken from a dedicated made CD and converted to MP3 before putted into finalcut. If i convert it to aiff instead it gives me files around 1 frame shorter than the mp3 files. "Sync Audio Capture to Video Source if Present" is on as well, like "thedirtyduo"s has.
Im lost (too)

10.6.8: audio goes out of sync in Netflix streaming and *.avi files

Hello,
This began happening a couple of weeks ago and it's maddening! There haven't been any software changes or anything recently.
At first I thought it was just a Netflix problem, or perhaps an internet connection problem. Audio will at some point during play, 'skip', and play the same audio over again (i.e., "Hello, Ja-Hello, Jack!"), and from that point on, the audio is lagged behind the video just a bit.
Then I began watching some *.avi files on my HDD today, and the same thing is happening with them, too! If I reload the browser or close and reopen the *.avi file, the audio will start out in sync again, but at some random point during playback, it will happen again.
Hope someone knows what's going on! Thanks!

For anyone who's interested, I found a solution to this problem. Once imported into Encore, the leader in on the video and audio files cannot be trimmed at all. (I had been trimming the beginning of the video and matching audio file to eliminate the 8 seconds of dead space at the start of the clips.) Although the trim took effect immediately in the Encore timeline and I could also watch it in preview in sync, exporting was another story. The audio track seems to retain the trim when exporting but the video track does not, hence the 6-7 second delay between audio and video.
I reimported the files to my project and left in the 8 seconds of dead space at the start and voila! The video and audio match up when exported.
Ideally the trim tool would just work as its supposed to through export and all, but at least I found a solution I can work with.
(As a note, the trim works just fine in export on Encore CS5. I only had this problem with Encore CS6.)

Video and audio goes out of sync when imported into Premiere

I have some videos ripped from some DVD that an acquaintance made, with an open source program called HandBrake, with the default "high profile" settings. When I play it both in VLC and in Quicktime, it plays just fine, but when I import it either in Premiere or in After effects, the video and audio goes out of sync (the video ran faster than the audio and when the video stops, the missing audio is trimmed).
Video info according to Premiere (in Spanish but you may get the meaning).

"HandBrake, these days, is almost entirely about H.264 video, aka MPEG-4 Part 10. HandBrake is migrating to quality-based encoding."
Hmmm. I use HC Encoder to make my DVDs because it's the only free encoder I've found with the much more professional Constant Q encoding option. But HC Encoder doesn't do HD sources for Blu-ray, so I've been wondering if I'd be stuck with the lame-*** consumer CBR and VBR options most encoders provide (including Adobe - hint, hint) when I eventually start working in HD. This is a very interesting program, Handbrake. I will have to check it out.

When audio goes out of sync..

In FCP7, when audio goes out of sync with the video track it came from (even when they are unlinked), a red warning box is displayed on the audio track and tells you how far out of sync it is, which easily enables you to resync.
Well, in FCX my audio went out of synce, but i didn't know it until i played back a segment i was working on, where i spliced two audio tracks and video tracks together. Right now i'm trying to fix the one audio track so that is synced up with its parent video track, but so far i'm just guessing that it's a good sync rather than knowing FOR SURE whether or not it's truly synced back up.
Is there any kind of work around, which enables you to resync in a manner similar to before FCPX?
Thanks

I am not sure if your problem has been solved already but here is the way to do that:
select in the clip in the timeline the part were the audio should be return in sync. use the blade-tool to make that part a seperate clip.
Higlight this clip in the timeline and use shift-F to highlight this clip in the browser. There it wil show up partially of course.
Use only the audio and put that part under the selected clip in the timeline where you need the original audio. remove the original out-of-sync audio.

Audio sync problems with greenscreen I have replaced the camera audio with my zoom recorder audio and it is in sync. When I apply greenscreen the audio goes out of sync. What am i doing wrong?? So frustrating..Thanks, Peter

I have replaced the DSLR audio with audio from my Marantz recorder and it is in sync with the dialogue. I apply green screen and the audio goes out of sync. Cannot seem to make it work. what am I doing wrong? Thanks, Peter

Thanks for the reply. I don't have time for this. is it time to switch to a different editor?

HELP! Audio goes out of sync after export!

OK, folks. I need your help. I have a looming deadline of THIS FRIDAY to hand this in.
I have a finished multicam edit of a show that runs 1 hr 20 min. It plays back perfectly in the timeline, all video and audio perfectly in sync. Looks and sounds exactly like what I need.
When I export the video as an H.264 file, the audio gets out of sync with the video by 13 frames! But that's not all... It doesn't happen to the entire audio track. There's about 50 minutes in the middle of the video where the audio goes out of sync. The audio at the beginning and ending of the video is lined up perfectly in sync. It's just the middle section that gets screwy.
What do I do?!
This has never happened before, and I've worked a lot with multicam in Premiere Pro CC before this. Never been an issue. I tried uninstalling and reinstalling Premiere, and also deleting all media cache files, but still no dice. I also tried copying the clips into a new sequence in the same project, copying the clips into a new sequence in a NEW project, nesting the sequence... nothing works.
My setup:
MacBook Pro Retina (Rev. A)
Premiere Pro CC (latest version)
Panasonic GH3 footage in 1080p 24p AVCHD timeline
3 cameras & 1 audio WAV file in Multicam
Any help would be greatly appreciated!

OK, I figured out how to fix it:
In Premiere Pro CC, click on SEQUENCE > DELETE RENDER FILES.
Try exporting the movie again.
It worked! I exported the same sequence, and it took a long while to re-render the audio files, but when it was finished exporting the audio and video were in perfect sync. I'm not sure what caused it, but this fixed it, so hopefully anyone else having this issue can save a lot of time by reading this.
Cheers!

Premiere CC export causes audio to go out of sync...mac & PC...various codecs...including flat passes...disk cache cleaned...render files deleted...what is going on?

Hey all-
This is troubling. I'm getting slight audio shift every time I export a project. We noticed it originally when our sound guy brought in the OMF & realized the timecode and audio ended up coming out off by 3/4th of a frame. So we tested it...
Exports to .movs / .mp4s / .mpegs
Brought them back in to the project....
Sound gets off by a 1/4th of a frame to 3/4th of a frame.
Then we started tested different files. Doing flat passes where NOTHING changed, just a re-export under the settings of the source file...
sound gets off by a 1/4th of a frame.
Tried media encoder.
same thing.
cleaned the disk cache...deleted render files
same thing.
tried it on a new mac pro. tried it on a dell running windows 7.
same.
thing.
So is there a solve for this or should we just stop editing in Premiere? On a few occasions now I've had clients say "it seems like it goes out of sync right there" and I've gone back to the timeline and checked to see it was fine. Now I wonder if much of the work I've put out since I made the switch last year has fallen victim to this.
Is there any kind of solve for this? Should I just stop using premiere to cut? Because this is a deal breaker, especially if I'm going to have to rebuild the project I'm working on in another NLE.

avanishdivya thank you, but this did not help. I did exactly what you told me in both cases.
I haven't overclocked my pc and both of the suggested media encoder methods failed, my pc crashed and turned off...
Any other suggestions ?

Audio locked at playhead, but goes out of sync if video is cropped

Hi,
Using iMovie HD 6, I have the audio locked at playhead, but if I crop part of the video (beginning or ending), the audio goes out of sync.
Here's what I've done:
1) Extracted audio from video
2) Silenced this audio
3) Imported audio from audio recorder (Edirol R-09HR)
4) Synced the imported audio
*5) Attempted to crop part of the video footage in the timeline... goes out of sync
How do I keep the audio in sync when cropping video?
Thanks!

Hi JohnDoe2009 - firstly, extracting the audio is not necessary in your case. Simply mute the video's audio, by reducing its level to zero - that is what actually happens when you extract the audio, after all.
It is my experience also, that locking audio clips to particular video clips is not fail-safe if further cropping is done afterwards, especially if that cropping is fairly substantial. Where possible, do the syncing after all crop-editing has been completed.
As a last check I always review the syncing before finalising the movie.

AME - Converting to MP4 and different FPS - audio goes out of sync

As described in the title.
I'm reencoding a 1920x1080 29,97 fps video into a 1280x720 60 fps video. Audio is AAC 44100 stereo.
Basicly a task that many of those free converters on Windows do smoothly. I use Mac...
I'm surprised that it goes out of sync, like 3-4 secs EARLY sound on a span of 2 mins video.
Settings here:
AME CS6 Fully updated
source: 1920x1080 29,97fps MP4 with AAC 44100hz audio
Target:
Codec: H264
Saves as : MP4
1280 x 720
60 fps Progressive - NTSC
CBR VBR1 VBR2 doesn't matter
Max rendering quality
Codec Audio AAC 44100hz (as source)
Any ideas ?

Because we stream at 60 fps and we have to convert all the materials we receive from our partners from the usual 29,97 to 60.
Thanks for your MVPaluable help.

Audio And Video out of sync in Final Cut, but not in quicktime

I heave searched the forums to no end to find the solution to this issue, unfortunatley, I have not solved the problem.
I am using Final Cut 4.5 on a G4 running OSX 10.3.4. This system has worked perfectly for years with no problems. Neither the system, hardware, or software has ever been changed on this machine. Suddenly last week, despite perfect sync while previewing the capture, the Audio and Video were of sync in Final Cut, but when checked in quicktime, there were no problems. That is how I eventually figured out this was a final cut problem.
By out of sync, I don't mean it is by a specific number of frames that can be adjusted and then everything is fine, the sync seems to drift so that if you edit the audio to be in sync in one part of the video, it won't be at the end. Also, it is out of sync from the first frame played, not a gradual drift.
This is definitely not an issue of frame rates or final cut settings as will be evident by the steps I took below to find the source of this problem.
This is what I did to attempt to fix the problem:
- Check drives using disc utility and repair permissions
- Remove Final Cut Preferences using Apple guidelines
- Switch hard drives
- Delete Final Cut and reinstall newer version of final cut (since the capture files played fine on Final Cut 5.1 on another machine)
- reinstall entire OSX 10.3.9, wiping the hard drive and reinstalling Final Cut 5.1
- switch ram slots, and even replace ram with different sticks from another G4 machine
None of these solutions worked. Is there some hardware problem with my G4 that is suddenly causing Final Cut to play audio and video out of sync?
Hope you can help, otherwise this otherwise great G4 is going in the dumpster!
Thanks

For what it's worth, I'm having what looks to be the same problem. Driving me insane. Here's what's going on-
Editing in FCP 6.0.2
QT was just updated to 7.3.1 the other day (hmm)
On an MacBookPro machine, OS 10.5.1
Software updater says everything's up to date of course.
DV-NTSC 24p (23.98) Advanced Pulldown Removal (footage was shot at 24PA on a DVX100b)
In Quicktime, the file previews fine, everything's in sync, everyone's happy. In FCP, the video and audio are wildly out of sync. I did a test inside of quicktime and sliced out a small portion of the media clip and did a "save as" and this small slice played in sync in FCP. However, this did not work for the entire clip. Clip is weighing in at 5.58GB for a 32 minute run.
I'm trying to multicam 2 tapes together and manually syncing these up is proving to be difficult at best. When anyone gets any ideas/leads/patches, let us know.

Audio and Video out of Sync in Encore 2.0

Here's my issue:
I opened a project in Encore 2.0 that was an Encore 1.5 project. I have one timeline with a 2 hour movie and the AC3 audio file that goes with it. Encore 1.5 played the audio and video in sync from the timeline and burned discs with the audio in sync. The video is an MPEG2 file encoded at a 3.1 constant bit rate.
In Encore 2.0, when I play the timeline, the audio becomes progressively out of sync as it plays. Within the first few minutes it's maybe a frame or 2 off. By the end of the film it is about 18 seconds off (audio is playing ahead of the video).
Is this a result of Encore 2.0 conforming the audio file? If so, how am I (or anyone) supposed to attain sync between video and audio in Encore 2.0?
I have Encore 1.5 and 2.0 both installed on the same machine. As a test, I opened the project in 1.5 and played it, everything was fine. I closed Encore 1.5 and opened the project in Encore 2.0, and the audio is out of sync.
Any comments, ideas or suggestions?
Mike

Joe,
I tried creating a project with the original WAV file and it's corresponding video and found that the audio and video were still out of sync. I did a little more testing and discovered that the audio is actually being played correctly, it's the video that is not being played correctly. Here's what I did:
I opened the WAV file version of the audio file in Premiere Pro and noted where a hammer hit in the video occurs (01;40;30;28). I then opened Encore 2.0 and imported the video and AC3 version of the WAV file, placed them in a timeline and the audio's hammer hit is right where it's supposed to be (01;40;30;28), but the video's hammer hit occurs at 01;40;43;18.
Next I went into Encore 1.5 and brought in the AC3 audio and video files and placed them on a timeline. I went to 01;40;30;28 in the timeline and the audio and video were both at the frame they should be at that timecode.
Seeing how the video appears to be playing incorrectly, here's some info on my video files:
I have 4 versions of the same film in varying encode rates with the same start and end timecodes. All four files were encoded on a Sonic DVD Creator authoring station using hardware to encode. The files are encoded at the following rates: 2.9 constant bit rate, 3.1 constant bit rate, 3.4 variable bit rate and 4.0 variable bit rate. They are each NTSC with drop frame timecode. All four files play correctly in Encore 1.5 but incorrectly in Encore 2.0.
This almost seems like a drop frame/non-drop frame issue. Do you have any ideas?
Mike

Audio and video out of sync on short recordings

I've scanned the discussions and see that alot of posters are experiencing
the same problem I'm having which is recording quicktime movies
and getting audio and video out of sync.
In most of those posts the responses seem to be that the problem gets
bad if you're making a long recording. I'm experiencing that, but...
...I'm also having the same problem on really short recordings...less than a
minute. I've coming video and audio out of my cable box, into a SONY DSR-11 VCR, then firewire out of the deck into the computer, recording the movies with Quicktime 7.1.6.
I know it's coming out of the cable box and then out of the SONY deck via firewire in sync because when I log and capture through Final Cut Pro, audio and video are in sync in preview and playback. I don't want to use Final Cut Pro to capture the movies because I want to end up with MPEG4, and I'd have to go through an extra conversion process out of FCP.
Any thoughts on why even short recordings through Quicktime are out of sync?
Thanks.

I'm having similar problems transferring VHS video to Quicktime. Another problem I'm having is when I transfer a VHS video to iMovie and then export the video to H.264 format, I have similar sync problems, even though the iMovie seems perfectly in sync.
I'm going to try to transfer several alternative video formats (video from my cable DVR, Video from live TV, and video from a digital mini cassette to try and figure out whether the VHS format is the culprit. Will keep you posted.
