Only some audio is off sync after Quicktime export

I am cutting simple man-on-the-street interviews together to build a narrative. I am shooting on a Sony HVR-V1U in HDV. I import everything fine, edit it, then export to QT using the following settings:
H.264
Video bitrate: 1372 kbits/sec
Frame rate: 29.97 for 25fps
Frame size: 640x360
Multi-pass
Quality: High
Sound: Format: AAC
Sample rate: 44.1 kHz
Stereo channels
128 kbps bitrate
When I play the QT, some of the voices are fine, but others the video is off sync from the audio by around 15 framse, and I have NO IDEA WHY. I've tried messing with the settings, re-importing, and nothing works. And the fact that it happens to some clips and not others, has left me just baffled. I've had to just re-export manually adjusting the audio. Anyone else have this problem? Any solutions or advice that I could at least try?
Thanks!
Mike

Thanks for the tip but I was trying to avoid having to put the clips into a video editor because that tends to cause it's own problems with sync as well. I actually found my answer via an obscure link to some comment on a forum detailing that .wav files (which I was using) will NOT stay in sync in Flash (regardless of the version) due to the particular way Flash compresses them. I switched all the audio to .aif and bam... instant sync. It sure would be nice if the default sound format Adobe uses in thier own Audition program would be compatible with ther own software! After all, wasn't that what the whole unification of the Creative Suite was about? So that all of their 'suite' would work with each other seamlessly?

Audio always off sync after converting .asf files?

Hi, my problem is that it seems that every time I convert .asf files the audio always ends up off sync. Many programs don't even convert them at all, like ffmpegX, but my favorite video converter VisualHub does convert, but like I said before the audio is always off sync. Does anyone know of any software that can reliably convert .asf to another video format without the audio messing up?
On a side note, I do have plug ins such as Perian and Flip4Mac that allows Quicktime to read the files just fine, it's converting them that causes problems. For reference, the particular files I'm having trouble with use the WMV3 video codec and wmav2 audio codec. I think that's the problem.

My problem is a bit different, though just as irritating. I can't believe Adobe hasn't fixed this given how long since the original post has been up here. I capture satellite programming from a professional c-band satellite every week. I use good old fashion Quicktime to capture 30 minute programs for later broadcast. Our job is to capture the video from the satellite, clip the commercials at the beginning and end of the program and then export a clean version as an MPEG2 file. Quicktime provides two capture settings: high (which provides a very large ProRes file in 16bit stereo) or medium (which provides a manageable H264 file in AAC stereo). Both are Quicktime files.
While I don't have sync issues with the ProRes file, the file that is captured using H264 and the AAC stereo gets pushed out of sync by just enough frames to make it necessary to fix. This is adding about 2 to 3 hours of studio time each week to our production given we have to process about a dozen of these files. Viewing the original quicklime files using the newest version of quicklime or the old Quicktime program and most other video players yields a perfectly in-sync experience; it's just when it's imported into Premier Pro CC 2014 that the sync. problem appears. One solution that has worked is taking the master file and exporting it again as a .dv file, but this actually takes longer than fixing the sync issue within Premiere. My guess is it may be the AAC audio process that may be the problem.
We only started using Premiere a few months ago and are already re-evaluating whether we should return to FCP. We were really like most of the Adobe apps within Creative Cloud, but we use Premiere to much to put up with such a major flaw. I do wish Adobe would monitor some of these forums; they have no idea how customer service plays a key role for future software purchases.

Audio Track off sync after importing RAW Materials to Premiere

English:
Hi there i have the following problem in Premiere pro cc:
I record Let's Play Videos via Nvidea-Shadowplay in 1080p / 60 fps / 30.000 kbps
I checked the material in VLC-Player and everything is fine.
Now i drag and drop the File in Adobe Premiere CC and the Audio track seems to be off sync.
This differs. Sometimes the Audio seems to be beheind, and in other cases it is a to early.
This is a serious issue for me, because it leads to lot of post-production in audio tewaking to fix this.
I have no Idea how to fix this, because the RAW Material i recorded works perfect, but the file is to big
to put on youtube, ofc.
Deutsch/German:
Hallo Leute, ich habe folgendes Problem:
Wenn ich Let's Play Videos in Shadowplay aufnehme und mir das Material dann im VLC Player betrachte sind Audio und Videospur 100% synchron.
Wenn ich das Material dann aber in Premiere Pro reinziehe habe ich bei manchen, nicht bei allen Videos das Problem, dass die Tonspur asynchron ist. Manchmal ist das Bild zu früh, dann wieder der Ton.
Das führt zu viel Zeitaufwand beim Nachbearbeiten.
Wenn ich das Video dann Raus rendere ist es immer noch Asynchron.
Ich habe keine Idee woran das liegen könnte...

What you're running into is variable frame rate (VFR) video. ShadowPlay and any other app that uses nVidia's hardware h.264 encoders will produce MP4 files that are VFR. Premiere Pro doesn't handle VFR vids very well at all; it's designed to handle constant frame rate (CFR).
To fix this, you'll want to transcode your MP4 files using something like Handbrake over to CFR versions. I've never used Handbrake for this, but I know others here have to great success. Search for phrases like "VFR" and "variable frame rate" and you should find a bunch of results.
I solved this using the ffmpeg command line application, which you can search for and download from various places.
ffmpeg -i <input.mp4> -hide_banner -vsync 1 -crf 19 -r 59.94 -vcodec libx264 -preset ultrafast -g 50 -acodec copy <output.mp4>
If you'd rather use a GUI, then check out Handbrake or other tools.

Irritating bug: playback final cut loses sync after quicktime export

this bug is bothering me for years already, and with every update i hope it will be fixed, but no.
everytime i export a quicktime (file/export/using quicktime conversion) final cut loses its sync in playback. then i have to restart fcp and the sync is ok again.
it's not a big problem, but it's irritating, especially when i have a director sitting next to me.
did anybody ever have this problem also? how can we ask apple to fix this?

Exporting what? And why? You mean each time you export something FCP stops working properly?
it's not a big problem, but it's irritating, especially when i have a director sitting next to me.<</div>
It's a huge problem, obviously. But I think your workflow is more at fault. You havent' explained why you must export something or to what format so it's difficult to know where to point you for debugging this for you.

I don't have this issue and I export something form my timelines often, either as still images or to provide myself with a prerendered movie that I can reimport.

Audio out of sync after exporting into Quicktime using current settings.

Quicktime file has audio out of sync when I export to quicktime movie using current settings.
Ok for about the first few minutes then, out of sync after about 10 minutes.
I shot the footage on tape with my Sony HVR-Z7u.
My Sequence setting is the same as the format of the footage as shown below.
Pixel Aspect Ratio: HD 1440x1080
Editing Time base: 23.98
Quicktime video settings: Compressor: HDV 1080p24
Audio Settings: Rate 48 KHz
Depth: 16bit
Clip format:
Pixel Aspect Ratio: HD 1440x1080
Vid Rate: 23.98
Compressor: HDV 1080p24
Audio Rate 48 KHz
Audio Format: 16bit

I recently moved and both of my editing machines were unplugged for a couple of days until I could get them set up. After turning them back on, the problem had disappeared. Perhaps leaving the system unplugged had allowed some of the internal components to reset? That's the only thing I can think of. At any rate, the issue is gone.

Capturing footage and audio is off sync?

I'm capturing footage and then play it back on the timeline. I notice that the audio is off sync, why is that? I use Sony DVCAM Deck to capture without altering the setting, in Final Cut Pro 6, and the audio became off sync. Any solution?
Thank you
Luis

Is it consistently off-sync? Like is it always 2 frames off? Or does it trail off, like it starts in sync and then it drifts out of sync after several seconds? I recently captured a bunch of stuff that was recorded with a DVX100 and the audio was 2 frames ahead of the video (sometimes it seemed like it was only 1 frame off, but 99% of the time it was 2).
Then another problem that crept up was when it got to the end of a tape, which would confuse Final Cut. It would stop, and then make the last clip captured play at 29.97 when it should have been 23.98, though the audio would play back normally. So it would appear to be in sync for a moment and then it would get way out of sync very quickly. What I had to do then was just babysit the capture of the last scene on the tape and stop it before it got to the end.

Some audio out of sync in after Export

Can using the built in Audio tools like Loudness, or adjusting the sound levels in the waveform cause the audio to go out of sync?
I'd say not...but that is what seems to be happening.
I have a 2hr 30 projet for a DVD.
All individual clips captured on Canon 5d 3 at 48khz 25fps
Project is 48khz 25fp, as set automatically when the clips were first dropped on the timeline
One particular group of 3 clips, seems to randomly and suddenly loose sync in the middle, sometimes at the start, some times in the centre, then often it comes back at the end.
Of the whole 2 hr 30 project only this bit is giving issues, all other clips have been edited in the same way, and are similar lengths,some longer, some shorter, all stay in sync. Max clip length about 8 minutes
In the timeline the audio stays perfectly in sync
I have re made the sequence of three clips , totalling 24 minutes long, probably 6 times now. and each time after adjusting the audio levels the exported audio has variable sync,
Also re imported the footage and tried again
No added audio tracks, just a single compound clip containing three complete clips, with the ends trimmed
Audio has not bee detached from the video.
All I am doing is adjusting the audio levels,
Hum On
Noise reduction to about 2%
Loudness On :

Uniformity 15%
First noticed this yesterday on a DVD burnt using "Send To Compressor" Create DVD
Also happens using the in built Share, to DVD, ot share To master File
Output settings are also 48khz and 25fps
If I do an export of the clip With no audio corrections, it is fine. But as son as I try and adjust the audio levels, it goes out of sync.

Audio is off sync with videos on Ipod Touch.

My Ipod touch does not want to seem to play the audio in correct sync with my videos anymore. I have not done or changed a thing lately. Does anyone have any ideas? Thanks. I am running firmware 1.1.5

Update My iTouch is downgraded to 1.1.5 successfully. I used a pc that had an un updated version of iTunes installed (7.6) and after 2 attempts using the power off + home combination described in the firmware 1.1.5 post, I was able to successfully "restore" to the latest "1.1.5" iTouch software. When the touch reset, before establishing a sync relationship with the pc, I reattached it to my mac and selected "new ipod" rather than restore from backup. I then synced and tested on of the previously screwed up videos. It plays without any audio sync problems. This processes is more or less what the genius bar instructed me to do. I was reluctant to download any software not coming directly from apple. If anyone knows where the firmware file is stored on iTunes PC version, I would greatly appreciate the location. I want to save the file on my mac now that I know this is a good version. When Apple comes out with 2.1, I want to have a fall back.

Video and audio do not sync after importing media into Premiere Pro

After I import my video which is in the .MOV format, I notice that the video is slow and out of sync with the audio. This makes it incredibly difficult to edit. Any and all solutions will be helpful.

Thanks for your reply. Excuse my referring to you as "Kevin". I'm new to the Adobe Community. I have also referenced another article which is seemingly a bit easier to fix for such a non-technical woman like myself. I'm going to try both solutions. Whichever works I'll be sure to reply to the thread with my findings. I found this article which provides the following solution: http://blog.flickharrison.com/2012/04/problem-solving-in-adobe-premiere-audio-glitches-and -sync/

Some mp4 movies not syncing after conversion

I converted some movies to mp4 and they used to sync perfectly and I could watch them fine. Now only some of the old ones sync but some give the error. 'cannot be played on ipod'. If i convert a movie now it plays fine. Am i missing an option as i don't understand why some movies converted in the same batch don't work now and some do . They are all mp4.

I have the same problems! Hope Apple will fix it very soon.

Audio out of sync after encoding

I'm hoping someone can offer a suggestion. I've encoded my sequence 4 times now and every time the audio is out of sync with the video. The sequence is about 2 hours long. It was shot on a HD flip cam, , 1280 x 720 (1.0) 30.00 fps, 44100 Hz. The sequence is HD 1280 x 720 (1.0), 29.97 fps, 48000 Hz-Stereo. They are the exact settings I've been using to make these videos for the past 5 months since upgrading to CS5, and this is the first time I'm having this issue. I usually make 30 minutes videos, this is my longest yet.
I've definitely had this happen before with cs4, but was hoping the upgrade to a better version as well as better computer would do away with these encoding issues. I dont' know what other info you may need, but I'm happy to provide more.
I'm exporting to window's media, NTSC Source Hight Quality, output 720x480, 48kHz, stereo. Everytime I export it, the video markers only cover half the sequence. I have to move them to cover the entire sequence. Not sure if that has anything to do with it.
I'm at a loss. Any suggestions would be so appreciated.
Jules

Thank you so much. I did have problems with Encore, but I hopefully got that resolved. This specific problem is audio out of sync in my media encoder. I can't test the project beforehand. It took 2 1/2 hours to encode and when I played the finished project, it was out of sync.

FCE-No quit option after quicktime export...

Hi everyone,
I've noticed that after saving a large movie as a quicktime file, that FCE does not give me the option to save and then quit. It saves the initial project fine, but I've had to force quit FCE from the dock.(maybe i don't have to?)
After this I have been fine to drag the FCE movie file to iDVD and burn away, so no probs there, but I'm curious as to why the application is still... I suppose "in use" having finished converting the file to Quicktime. (I hope this makes sense).
The only reason I've wanted to quit FCE was to ease the workload on the machine from having large apps./projects open whilst it's trying to burn.
Am I being over-cautious here?
BTW, the discussions here have been a fantastic help in my first 2 months with FCE, cheers to all contributors !!
PB 1.67, eMac 1.25 Mac OS X (10.4.5)

I don't know the differences between FCE and FCP, so not sure how much help I'll be...
I can't imagine you should be having to force quit FCE after an export. Could be corrupt preferences...
search this forum or FCE forum for 'FCP Rescue'. There may/may not be a version for FCE, but it might help. There are also manual processes for this as well.
Hopefully someone else may chime in with better info.

White Screen in ITUNES after Quicktime Export. Samsung CL65

I have a Samsung CL65 digital camera. When I shoot movies I transfer them from my camera to IPHOTO, along with my pictures.
When I open the movie in IPHOTO it opens in QUICKTIME and there is an option to EXPORT TO ITUNES. No matter what quality I select (Iphone - Appletv) the result after the export in ITUNES is always a movie WITH SOUND but with a WHITE SCREEN for video.
I have 3 digital cameras, samsung, panasonic and canon. I only have this problem with Samsung. The video file that the Samsung camera makes are mp4.
I want to be able to export from Quicktime to Itunes without getting a white screen movie with sound. Any ideas????

I want to be able to export from Quicktime to Itunes without getting a white screen movie with sound. Any ideas?
The Samsung video codec does not appear to be "conversion compatible" with any application employing the QT embedded structure. It took me over an hour to find what I assume to be a true, non-YouTube converted "CL65/ST1000" sample file for testing purposes (i.e., it would have been a lot quicker if you had uploaded a sample file for testing) before actually running a series of tests under both Leopard and Snow Leopard. Basically, it seems you can use an alternative application which contains its own codec and does not need to "prepare" the file content before initiating the conversion. I found that the free HandBrake application which defaults to the X.264 codec worked for me. As I consider not changing the frame rate rate to be more important then retaining full 720p dimensions, I only ran tests using a 960x540 @ 30 fps setting for TV device.

Audio out of sync AFTER importing

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

My problem is a bit different, though just as irritating. I can't believe Adobe hasn't fixed this given how long since the original post has been up here.

Our job is to capture the video from the satellite, clip the commercials at the beginning and end of the program and then export a clean version as an MPEG2 file.

While I don't have sync issues with the ProRes file, the file that is captured using H264 and the AAC stereo gets pushed out of sync by just enough frames to make it necessary to fix. This is adding about 2 to 3 hours of studio time each week to our production given we have to process about a dozen of these files. Viewing the original quicklime files using the newest version of quicklime or the old Quicktime program and most other video players yields a perfectly in-sync experience; it's just when it's imported into Premier Pro CC 2014 that the sync. problem appears. One solution that has worked is taking the master file and exporting it again as a .dv file, but this actually takes longer than fixing the sync issue within Premiere. My guess is it may be the AAC audio process that may be the problem.
We only started using Premiere a few months ago and are already re-evaluating whether we should return to FCP. We were really like most of the Adobe apps within Creative Cloud, but we use Premiere to much to put up with such a major flaw. I do wish Adobe would monitor some of these forums; they have no idea how customer service plays a key role for future software purchases.
