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.

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.

Why is Audio out of sync after encoding?

I have encoded a 60 minute film using separate video and audio files -- quicktime for picture, AIFF for audio. In the DVD Studio Pro project, they are perfectly in sync. But in the encoded DVD they are playing out of sync by over 1 second.
I've encoded the same movie with different versions of the soundtrack several times before with no problems.
Anyone have any ideas of what has happened and how to fix it?
The Quicktime and the AIFF were on different drives when I was building the project. Could this have had any effect?
Using DVD studio pro v4.0.2
Powerbook G4 Mac OS X (10.3.9)

Nope, I am a strong believer if it ain't broke do not fix it, and personally I loved 10.3.9 - in fact I say away from updates unless absolutely needed and then I bring them onto different machines. Unless something changed in your system, I would try standrad troubleshooting (repair permissions and delete prefs) and A.Pack the audio
Not to say I do not have machines running Tiger, but Tiger (particularly some of the newer versions) I find to be a PITA - around 10.4.6 or so there are weird security things happening which messes up installing software. In fact I just zeroed out my tiBook, and did not add some software that I forgot about until after 10.4.8 was on and it does not install. I would have to zero things out again. Install the software over 10.4.1 and then try again.
Unless you want the Universal Suite (which is good for most things except DVD SP which has issues) nope, no Tiger none of the new stuff, unless you have a few machines to play with

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.

Audio out of sync after using h.264

Hi
After using compressor to encode an HDV sequence the audio progressivly falls out of sync as the sequence plays.
NAy ideas.
It was working
Thanks
gary

Are you playing it from your internal hard-drive / usb pen / usb / firewire / esata...
What it was working? The original file? What? The encoded file?
Are you playing the encoded h.264 in your fcp (?) in quicktime (?) where?
You can´t say you´ve encoded a file and it´s not running if you don´t give us details!

Audio not in sync after encoding to H.264 Blu ray

I have recently been trying to author my first blu-ray and keep running into new problems everytime I think I find a new solution. My new problem is that when I encode my sequence from Ppro CC to H.264 Blu-ray and place the video file and audio file into Encore CS6 the audio seems to be falling out of sync. I tried placing both files into a new PPro sequence and checked the playback and they are also out of sync there.
Things I've tried:
1) I went back and just encoded the audio from the sequence but this time I switched the audio coding to DD 320 bitrate instead of PCM. When I placed this file into the PPro sequence the playback was perfect. However, when I try placing the same two files (video and audio) into Encore they are out of sync.
2) I decided to take the encoded video file and place it back into the original PPro sequence and use it to replace the original video track. The playback again fell out of sync. Since this sequence had the original pre-encoded audio track, I came to the conclusion that it is actually the video that is not keeping up with the audio once encoded.
I am trying to encode to 1920x1080 HD 23.967 fps H.264 Blu Ray. I know I can just encoded to .avi match source and then let Encore do the transcoding, but figuring out this problem is a learning experience for me. Does PCM or Dolby Digital make a difference? What is the best way to do?

It sounds like things went wonky the first time around. Try exporing the whole thing again.
PCM is higher quality. Blu-rays have a lot of room compared to DVD, so I feel it's often the better choice. I'd recommend using DD only when you have to. But considering that I've put 3 hours of HD onto disk and still only filled 17GB, I think it's the very rare occasion when you'll run out of room and have to use DD on Blu-ray.

Audio out of sync after import.

Hello. I've been doing some game recordings with Nvidia's new ShadowPlay. The recording says it is done in "1080p @ 60 FPS with H.264". The recorder outputs into a .mp4 file. When I watch the raw footage, it is all properly synced. However, when I import it into Premiere, it is always out of sync without fail. I know very very little about the program, and have been trying to learn as I go, but I can't seem to figure out how to re-sync it. For now I've been having to cut the sound into parts and adjust the rates manually to get it to sync back up, but this is insanely tedious.
If I can give any more information, just ask for it.

I'm not entirely sure what all of these are, sorry. Source monitor is desynced. The default window in the top right corner where the clip is displayed is de-synced. Output is de-synced. I notice that the Video & audio are the same link in the timeline, but the audio cuts out early. I tried cutting out the blank audio and using the rate stretch tool, and that didn't help (not even sure if that's the right tool). I also noticed that the video in the timeline is longer than the original. I've managed to sync the start and ending using the rate stretch tool, but the middle parts are always still de-synced. It's driving me nuts.
Hi Sylfaen1,
In my experience, whenever anyone captures game play there is usually some framerate anomaly in the exporting process of the host application. You say your footage is 60fps and is .mp4, I would verify that. Right-click (or control click on Mac) and choose "Properties." See if your frame rate is indeed 60fps. If it is another frame rate, or is variable, you might have sync problems in Premiere Pro.
If that is the case, you will have to transcode the video to another format with a standard frame rate. You can use Adobe Media Encoder to do that.
Thanks,
Kevin

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. 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 out of sync after Log and Transferring

So, I'm working on a project for school and I shot everything on a Panasonic HVX200 at 720p/24fps. I have everything saved onto a LaCie external and is connected via USB 2.0. When I go into Log and Transfer, all the clips look great and playback without a problem. But, after I "Add Clip To Queue" and try to play it back on the timeline or canvas, the audio is out of sync (it's almost twice as fast) and the video almost looks inferior.
Any advice would be great. I really want to start working on this project, since it's due Thursday afternoon.
Thanks and regards,

In the P2 Import window...in the P2 Browser, there is a little sprocket drop down menu. Click on that and choose PREFERENCES. Uncheck REMOVE PULLDOWN and then try importing again.

Audio out of sync after splitting clips

When I import a video file into PE11, everything is perfectly fine and synced up. After I split the clip and merge it in several places (removing commercials), the audio and video for the later clips seem to drift out of sync by about half a second. The video and audio are always linked together so there's no reason for it to be drifting.
I am able to manually unlink the clips and shift the audio back into place, however, this is an annoyance. I've tried working with several different video formats and so far, no luck. Any ideas on how to fix this?
Thanks.

You are correct, I'm using a Hauppauge HD-PVR2 Gaming edition to record and it works great!
I had been using MP4 files at 1920x1080, 29fps, 48kHz audio, etc. When I record with the Hauppauge, it automatically sets up the file to accomodate the source. Tried switching to M2TS files on the caputre and it made no difference.
Project settings seem to match the source:
It's just very strange audio and video are both fine until I edit it. Plenty of horsepower on my PC too: i5 3.2GHz Quad-core, 16GB RAM, NVIDIA graphics card (forget the model), WIn 7 64-bit.
Thanks for the help!

Video & Audio out of sync after update

Ever since I updated my MacBook Pro to OS X Yosemite v10.10 last week, all videos are out of sync with the audio. It wasn't just on Safari while playing YouTube videos or DailyMotion videos, but also when playing videos files on my computer. For short videos, the audio is just a second ahead or behind the video, but for long films it can be minutes apart.
Does anyone else have this problem? Can anyone tell me what caused this and how can it be solved? Thanks so much!!!

I have the same issue and it started 3 days ago. This happens with anything I'm watching, netflix, huluplus, youtube, crackle, anything that has audio and video. The biggest issue is that it's also affecting iMovie and Final Cut pro X. This is a MAJOR issue given that I make a living editing video. I hope somebody can find a solution for this issue.

DVD & Blu-Ray audio out of sync after export

When I use FCP X's built in DVD or Blu-ray export option, about halfway through the video, the audio becomes out of sync and becomes ahead of the video.
How can I fix this?

Freddy,
You will see that I am experiencing the same issue with my DVDs and BDs per my question 3 hours prior to yours. It never was an issue until very recently. I may have a solution. Realizing that my audio was acting as if I had "Drop Frame" audio attached to "Non-Drop Frame" video, I went back to my source material to verify my acquisition settings. All elements of the production were recorded appropriately as "Drop Frame." Playback on the "Timeline" (Passé now) was perfect. No audio sync issues there. So I felt it must be some rendering setting within Compressor and the render engine. When you go to Compessor (Send to Compressor), you will gain access to the audio render settings for both DVD & BD. Typically, the "Retiming" under the "General" tab of the Audio Inspector is set to "100% of source." I Went ahead and checked off the radio button below that to render the audio at the exact duration of my program (nearly 3 hrs long). I did this for the DVD version of the program and placed it into DVD Studio Pro to replace the bad sync audio. Well wudda ya know....it worked. I haven't burned the DVD yet, but that is next. I suspect that if this works for the DVD, it may work for the BD render as well. Wish me luck. I hope this helps.
On a side note: If all else fails, render a MASSIVE master file and use that in Toast to make a BD. Not the best option, but it will get you out the door.

Newbie Help? Audio Out Of Sync After Capture

Please help a newbie to this great forum:
I use Final Cut Pro HD and import Sony DV tapes which were shot with a Sony VX-2000. Once recorded, I Log and Capture the tapes as I play them on a Sony GV-D 1000 NTSC player - the little "Walkman" of DV tapes.
If I import four tapes, chances are in two of them the audio will be out of sync with the video by half a second or so, and I have to manually reposition the audio track in the FCP timeline. The other two tapes will be ok.
How do I tackle this??
G4 Mac OS X (10.4.7)

Oh, sorry. I knew a musician years ago whose business card read "The Lone Arranger."
I personally don't care what you call yourself; and as long as it's not obscene you're doing fine here in Apple discussions.
DV tends to drift over time when shot with unlocked cameras. That may be your issue. The way to work around this is to capture in smaller chunks, say 15 -20 minutes.

Audio out of sync after DVX100A capture

Using FCP Studio to capture 24PA footage from my DVX100A, when I preview the audio during the capture it's perfectly synchronized with the previewed video, as it is on my camera display. But the moment my capture is done, the resulting FCP clip (as well as the underlying Quicktime movie file) is completely out of sync. It appears - though it's hard to tell - that the audio and the video are in sync at the first frame, though almost immediately, the audio starts to go faster than the video, so I hear my actors' voices before their lips form the words. I've tried adjusting all of my capture settings, capturing to different hard drives, and so on - nothing seems to work. There's plenty of free space on my dual processor G5 Mac, and I've edited many hours of 24PA video on this system already without a glitch, so I'm doubtful that dropped frames are the problem. More likely that I'm somehow capturing the video wrong, but I'm clueless at this point as to how to fix the problem. Thanks in advance for any light you can shine on this!

In checking my settings, I inadvertently tried playing the DVX MiniDV tape for a few seconds before starting my Capture Now. Wonder of wonders - it worked. I guess the problem was just that FCP didn't have time to read the timecode at the very beginning of the tape, or something like that. I let 'er play for two or three seconds first, then began my capture, and everything was nice and in sync. Thanks for your help on this!
