After Bad Frames Audio is Out of Sync

One of my HDV video clips has a few bad frames and after that point all the audio is out of sync, but only within Premiere Pro CS4. When I play the clip in Windows Media Player, all the audio remains in sync after the bad frames. I opened the clip in CS3 and the same problem occured. How can I get it to play in sync within Premiere, like it does in Windows Media Player?

I have the same problem with CS5 and some source video I captured off air. Strangely enough, in one instance I had 2 corrupt frames but the audio survived the problem, but in another case, the audio stream became noise. Hopefully someone will answer this question on how to fix this in Premiere. As you point out, media players seem to have no problem dealing with the missing information.

Audio is out of sync after capture.

I'm attempting an firewire capture from a DV source. When I'm logging clips and previewing them, the sound is fine, but when I view them after capture the audio is out of sync. I think I'm having timecode issues, is there any way around this?

I tried watching them in the timeline and viewer, all out of sync. No external monitor. I did get a message once about dropped frames and something else, it said I might have these issues, but it didn't tell me to change settings, just told me it was gonna happen, lol. So, I don't know where to start to fix it.

Audio falling out of Sync after importing into PP

Hello there,
I'm relatively new to this, so please when you're helping me, dummy it down as much as you possibly can.
I've been using Xsplit to record games while I play. I recorded a ~2 hour video and toward the beginning of the video it seems to be pretty a-okay but later in the video when I play it in premier pro, the audio starts falling out of sync.
I have no idea why it does this or what to do. When I play the original raw video the audio and video are both on time.
After googling this issue for about 40 minutes (and i'm not 100% sure what this means but I have a general idea) I read somewhere that the reason why the audio was out of sync was because xsplit uses a "variable framerate".
Not sure if this is true or not, but regardless, I tried exporting numerous times and the audio STILL falls out of whack.
I looked on xsplit and there was a setting that i could enable to force constant frame rate.... is this a solution to that problem?
Please, help me.
Thank you.

If your current video file DOES use a Variable Frame Rate, it will not edit properly in any version of Premiere
Force your software to create a Constant Frame Rate file and try again

Captivate 6 editing - on timeline, audio is out of sync after pausing

I am trying to create a software demo for my company. I am using the HD video and then have imported audio recordings over the video.
The big work portion of this project is adding call-out smart shapes on the video during certain portions to highlight what the voiceover is discussing. However, when I pause the timeline so I can add a smart shape, upon resuming from the pause, the audio is out of sync. This happens even if I hit Stop on the timeline, and use my mouse to move the playhead.
This is adding significant amounts of time to my video editing process, to the point where I am missing deadlines for having the videos created. The only solution I have found to guarantee that the call-out smart shapes are in sync with the audio instructions is to Play the timeline from the very beginning, each time after pausing the audio.
Is anyone else experiencing these issues, or know of a way to fix it? This is adding enough time to the editing process that our company is looking into other video editing softwares to replace Captivate.

I always copy the entire PRIVATE folder from camera to hard drive, and then importing from that hard drive folder in to project.
I am saing original, becouse I do not convert them to diferent format. And how could be the original files of video and audio out of sync???
I am using Premiere for 10 years, I am not new to this software, but never had this problem.

DV import - audio is out of sync 3 frames

This never happened to me in FCP, so curious as to why audio is out of sync 3 frames...
Footage is DV/NTSC 48K/16 bit, (footage is not shot w/this camera but) I am importing with my SONY hdr-hc7 (as usuall).
Thanks

Hi, thank you for your responses...
I know the sync on the actual tape is fine because I also captured into FCP to compare, and the audio was fine there... I also played back directly on a TV from the tape, and it was also okay. I noticed more when I actually exported my edited spot viewed in QT player, and it was out of sync. That is actually where It was most noticible... Then I opened a captured clip directly in QT Pro 7 and it was out of sync. I then imported the clip that I captured via Premier into FCP, and again out of sync...
This has never happened in FCP in my many years of using it... I tihnk it may be a Premier Bug, as I searched and found some similar sounding issues.
Or perhaps some setting was wrong, who knows. I don't know how much longer I will be capturing DV but if there is a fix out here it would be great. And its not a huge issue, but it is rather cumbersome having to re-adjsut each clip by 3 frames.

My audio goes out of sync after import

I have a bunch of masters of 1h documentaries that I've done using Adobe Premiere CS6. I've exported the masters using exactly the same specs:
Apple Pro Res 422 (HQ), 23.98fps, 1920x1080p, 48kHz, 16b, PCM audio.
I have to do some changes on the masters of these shows. They all play fine on several players like VLC, Quicktime, Mpeg Streamclip, etc. However after I import the masters into Premiere Pro CC, 3 out of 10 shows get the audio gradually out of sync, even on the source monitor before I put them on a timeline. The behaviour continues even after I place them on a timeline.
The project settings are the same as the masters and so are the sequence settings. I've tried to recreate the project, delete and re-import, duplicate the file and import that, and no matter what I do the same 3 masters go out of sync after the import.
I've tried to find a solution in many forums and despite noticing that several people have the same issue, no one has a valid solution for my problem.
I cannot go back to CS6 since my company updated their systems to CS7 so I can't even cross check.
Any suggestion will be most welcome.
Thanks in advance peeps.

Couple of suggestions.
First, rather than opening the Master export, go back to the original project. That should open fine in CC.
Second, with a CC subscription, you do have access to the full CS6 suite.

Audio moves out of sync or alignment with video after moving clip

I have a video clip with it's detached audio on the secondary timeline. The audio has been broken apart so that I can edit each individual audio track. But I still want to keep the audio linked and synced with the video. When I select the audio and video and move the clip, the audio moves out of sync(by a frame or two), and isn't locked directly under the video the way it should be, or the way it was before I moved the clip. I notice this when I zoom in really close and the audio tracks are a frame or two off. In some cases, the audio tracks get increasingly out of sync the more I move the clip. This shouldn't happen when I select everything together. Has anyone ever experienced this or is there a solution to avoid the audio getting out of perfect alignment with the video? Thanks

Yes, it would probably be best to just turn it into a compound clip. I'm relatively new to FCP X, and I'm coming from FCP 7. In FCP 7, I like being able to see both channels of audio under each clip. So, what I do is adjust the audio levels for each channel separately. I might add keyframes to one channel and leave the other channel alone. In FCP X, it seems like the only way to edit or adjust the separate channels is by breaking apart the audio. Then I can see both channels of audio and I can add key frames, etc. So, I just need to be able to see and edit both audio channels, independently.

Audio goes out-of-sync after adding photos to video

iMovie HD 5.0.2 here. I have one main 10-minute video clip and am trying to splice the video to include a few photos, which maintaining that video's audio track throughout.
After importing the video, I extracted the audio. But when I dropped in a photo, any video AFTER that photo is now out-of-sync with the audio track. (I'm not really fiddling with the visual timeline; I just split the video clip at playhead, insert photo, and any video after the photo winds up out of sync.)
Is this a problem with the dated software? Is there a workaround? If I should upgrade, what should I upgrade to? I really love the simple video and audio timeline of iMovie HD; it's perfect for my needs and I don't want to lose it...

OK
I'm a soft head. Now I understands what You want to do.
OK there is a smart way to exchange video for a photo but keeping the audio. BUT
I use a much more raw way of doing this.
I import my photo. Set a duration for it eg. 4 sec => 00:00:04:00 exactly
then I select the video clip
Extract sound - so that I don't affect this when doing the brain surgery
Cut in the video part away exactly 00:00:04:00
Select the photo clip - drop this before the un-needed video clip
Select the un-needed video clip and delete this.
Now I've replaced a pice of the video with a photo but the sound flows as it
was un-tuched.
I always work this way - think it has to do with super-8 film editings during
the stone-ages.
There is a function in iMovie that does this - replace action but I've never used it.

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!

Audio Drifts Out of Sync After Demux

Hi,
I demuxed an hour-long program from DVD to .m2v and .ac3 using MPEG Streamclip. The audio drifts out of sync very gradually, and by the end is way off.
I don't want to re-compress the audio, as it is already AC3. According to Quicktime, the video is 29.97 fps, and the audio is 16-bit 48 khz.
When I used to Export to DV option, everything stayed in sync. I can't go this route, however, since I can't afford to re-compress anything (I'm making a new DVD from this old one). Just an FYI that this worked.
Ever run into this problem before?

I am using version 1.9. In the preferences pane, I don't have anything checked.
To reiterate, all I'm trying to is demux the DVD as-is and bring those assets into DVD Studio Pro for an updated project. Not using FCP anywhere in this workflow.
Looks like I left out an important piece of info, though...When I demux the audio stream to AC3 (its original format), and try to import it into DVD Studio Pro, I get the error message: "Variable bit rate audio assets cannot be imported." I am not sure how the client originally encoded their audio, but the fact that it stays in sync on the DVD led me to believe they didn't do anything wrong. Could this VBR be throwing the audio off during the demux? The only instances where I've noticed it's out of sync are when I export to an uncompressed format like AIFF or WAV, and can actually view it.

Why does my audio slip out of sync when exporting?

I am exporting an HD edited video. I shot 1280x720 & editing in FCP 6.0.5. I am using APPLE PRO RES 422 1280x720 30fps 48kz . Should it be (HQ)?? - I do not select re-compress all frames or make self-contained. I just want a QT reference file to view and then burn a DVD. My clip is 43 minutes long. HOWEVER, the audio drifts out of sync BIG TIME. Why is that??
Here are my sequence settings:
1280x720 Aspect Ratio HDTV 720p (16:9)
Square Pixels
H.264
Audio at 48kHz

That's what I thought, however, when I play back the .mov file after exporting using "current settings", that's when I experience OUT OF SYNC audio. Do I ignore that and drag and drop that file into iDVD and let iDVD crunch it??? Is it just the playback of that .mov file that is out of sync?

Captured audio is out of sync

I captured a 12 minutes clip using Capture Now in FCE 3.5 from my PAL camcorder Canon MVX4i (=Optura 600).
This is the first time it happens to me: the captured clip has the audio portion out of sync with respect to the video by 5 frames. So, the audio is consistently 5/25 fps = 0.2 seconds late during the whole clip. Unfortunately, this is quite visible when people are speaking.
As a workaround I set the clip in the timeline, unlinked the audio, shifted the video portion forward by 5 frames, marked the clip in sync and relinked (BTW it took me a while to find out that 5 was the right value: lot of tests adding and subtracting a frame at the time, and listening ...)
I doubt the cause is the camera, so my question is: what is the cause of this out of sync ?
Thanks
Piero
Some additional info.
I used the same setup I've been using so far: camera directly connected to the iMac, capture to an external firewire hard drive, use of Capture Now just because it's faster with short movies. Tha movie was shot with 16 bit audio. The shift is the same all along the clip.

Hi Ian,
I'll check tonight once more, just to be sure. I doubt though, because being aware of the possible impact of the 32KHz, I am usually careful. But I also know that editing after 11 pm is not recommended to me... I might do silly mistakes...
In any case, I'm afraid there is a problem with the tape. Could a damaged tape causes out of sync during capture ?
Thanks
Piero

When exporting separate audio and video streams, the audio drifts out of sync

So this is my first slightly larger project in Final Cut Pro X.
When I export my finished project (around 12 minutes long) straight to quicktime, it plays back perfectly.
When I export using compressor, the resulting audio and video streams are two different lengths. The audio comes out a full second longer. If you try to lay them down in a program like Adobe Encore, the audio starts out perfectly in sync. Two minutes in you notice the video is slightly out of sync with the audio. By the end of the video it's comically bad, over a second out of sync.
What's even more vexing is if I try to take the quicktime file that IS in sync upon playback, and try to convert it burn that to a dvd or blu-ray using toast, the problem re-emerges.
I triec searching around, but most of the suggestions that came up were vauge, like, "Upgrade to a real program like Final Cut." (This was in reply to people who were using free software programs.)
I did see one idea surface where 44 and 48 kHz sampling rates don't play well together. So I combed through my project and found all the 44.1 songs that were used, and swapped them out with upsampled versions. Nothing changed. It didn't sound like it would fix it, as people usually said it was a specific amount of frames off, not something drifting out of sync.
So the question is, does anyone have any suggestions on what could be causing this? Thanks! :-)

Project settings can be accessed and changed by selecting the project and pressing command-J. Then, in the inspector, click on the little gear in the lower-right hand corner to access the settings.
Why are you trying to output video/audio separately? If the content plays in-sync when exporting a quicktime movie (using current project settings), you could try separating the video/audio using MPEG Streamclip as a second step instead of using compressor. For audio, don't change the sample rate from the project settings, and use uncompressed audio (AIFF) as the output format.

Audio shifts out of sync. cannot match up picture to audio

i have a video that i downloaded from a stream. however, in fcp 6 the audio is out of sync with the picture. when i reallign the picture to audio, the audio gradually becomes more and more out of sync the further you go down the timeline. ive tried resampling, changing bit rate, and dropping frames. am i doing something wrong? i would appreciate any and all help. THANKS

Interesting you asked that "side question". Recently, I was ripping CD tracks that I know are 44.1 sample rate and I needed to re-sample them to 48k for the FC project. I knew what the 48k should sound like as it was recorded on the cameras. After I re-sampled the audio, it was still off and I have done this at least 100 times. If I remember correctly, I had to export the audio track, selecting 16 bit, 48k before it matched up. Just changing the sample rate of the audio project did not re-sample correctly even though a dialog box popped up asking to resample to the new rate. I use Cubase for mu audio work so I can't explain the process in STP but I think you get the idea. Yes, the duration should change if re-sampled correctly.

Why does the audio go out of sync on my Apple TV?

Over the past couple of weeks I have noticed that the audio goes out of sync with any streaming video on my Apple TV (3rd gen) after about 20 minutes of usage. I have never had this experience in the past and am not sure why it is happening, but one theory is that it has something to do with AirPlay. I'm pretty sure that this problem only happens after I use AirPlay to connect my Mac to the Apple TV. I'm not sure if this is the exact source of the issue and was wondering if anyone else has experienced this, and if so, what solutions may be available. Thanks.
