IMovie: I uploaded HDV video from a Canon HV20 and then to YouTube. The video and the audio are out of sync. The audio seems to precede the video by a tiny bit which is disconcerting. Any recommendations about how to correct this? Thank you.

I downloaded video via iMovie from my Canon HV20. The video was in HDV. I then published it to YouTube and Vimeo and in both cases, the audio is out of sync: the video precedes the audio by a fraction of a second. The original is fine as viewed in the camera.
Any suggestions as to why and how to correct it?
Thank you,
David

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.

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?

I made a video in iMovie and a few minutes in, the audio goes out of sync.

How can I fix this? I've googled and tried suggestions such as detaching audio then exporting. It doesn't fix it!

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

Top clipped when I import a wmv video. Please Help.

When I import a wmv video into premier elements 9 the top part of the video is clipped. The video plays fine externally with windows player, and plays in premier but the top is clipped. This happens for any video I try to import. The video properties are as follows...798 w x 480 h, 25 frames/sec, 1858 kbps. I definitely need help with this one, as I cannot even start a project.

In case you are missing the Announcement, it should display
Announcement: Windows Update Causes Display to Be Blacked Out
Hide Details
MicroSoft has issued an Update for Windows, that is causing problems with Displays. The following is from Talbot McInnis, who tracked down this problem, and offers a fix:
"MS bulliten MS13-057. Specifically, on XP kb2834904 and on windows 7 kb2803821 is causing a problem
For us, it occurs when decoding WMV9 files. Not all uses of WMV decoding are affected, but I confirmed that when connecting the WMV decode DLL to a sample grabber for RGB32 video, the frames arrive black on top, so that points directly to decoding internals of the WMV Decode dll.
You can uninstall these windows updates to resolve your problem."
There are several threads on the problem that this Update is causing on the PrE and PrPro Forums, so one can get more details. So far, there is not another fix from either MS, or Adobe.
Also, see this Adobe KB Article: http://helpx.adobe.com/premiere-pro/kb/wmv-files-corrupted-import-or.h tml
There have been many, many threads on the subject..lots of helpful hints on the matter of deleting the offending Windows Update kb. Major points that were offered include:
a. for the present, set your Windows Updates so that you require notification for any downloading and installing of them.
b. if you catch the offending Windows Update kb in Windows Updates Important Updates, then right click that kb and select Hide...that is supposed to block it from further activity.

When viewing online videos (news, sports etc) the audio is totally out of sync.

I use three emails (gmail, comcast and juno) and when I click on anything that has a video, the audio is out of sync with the video. I originally thought it was only Comcast.net news but their techs have not been able to improve matters. So I ran tests on the others and found they had similar problems. Cursory checks of my PC, Acer HD monitor and my two small speakers didn't reveal anything. That doesn't leave much other than Fire Fox.

If this were a project that I was involved in, I would recapture the media at the correct frame rate and rebuild the sequences correctly.
Moving from production, to post production, to delivery is a series of steps, and the success of any particular step is based on having all the preceding steps done correctly.
Shortcuts and workarounds tend to create awkward and difficult problems, that often only surface late in the process.

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?

When I use media manager to upres clip audio goes out of sync

I captured a clip and put it in DVNTSC 48kHz timeline at OfflineRT NTSC (Photo JPEG) then used the media manager to create a new sequence at full DV NTSC 48kHz res. I choose "Create offline", "set sequences to DV NTSC 48 kHz", and check all the boxes. I save a new project, open the new timeline and recapture the clip. The video looks great--it recaptures in full DVNTSC 48kHz res. But the audio is out of sync (by about 28 frames it looks like). What am I doing wrong? (This is the first time I'm trying this offline-then-online-process.) thanks.

Try exporting the iMovie project as a single full quality dv format quicktime file.
I use iMovie6 HD and this is my usual procedure that works well.
Make the movie in iMovie, will involve many separate clips. When finished, export (share) as a single full quality dv format quick time file. When I have an hours worth of smaller projects, I create a new iMovie project and import all of the quicktime .dv files for each separate short project. I add chapter markers in this project, then share with iDVD. I then burn an hours worth of stuff at best quality and distribute to family and friends.
iDVD seems to work better with iMovie source that has fewer clips.
BTW: Are you having problems with standard def or hi def iMovie source. Another part of my procedure is that I take the raw tapes and download the entire thing into one iMovie project. I don't edit or change the footage at all, just want to archive to DVD for posterity. In this case, I want to share the iMovie project with iDVD directly. This has worked OK for standard def projects, but my first hi def project (1080i) that I tried, the sound was out of sync. To fix this, I had to create a regular DV widescreen iMovie project, and drag all the clips into it from the HD project. It took over an hour for my humble mac mini to convert the files, but I was then able to share with iDVD and the finished DVD worked ok.
Hope this helps.

Audio is out of sync when placed in the timeline!!!

When I play a clip in the viewer, everything is fine, but when the clip is placed into the timeline and played in the canvas, the audio is out of sync by about half a second. I noticed that even when I view the sound waves, what I hear does not match up with where the playhead is. This is extremely frustrating and I have currently resulted to physically moving the audio to match it up, something that I do not want to do for the duration of my film.
I read in another post that the video and the audio could not be at the same level. How can you tell if the video and audio are at the same level??
I have FCE 3.5 if that makes any difference. Any help would be much appreciated!

How was this clip imported? If it was captured/ingested, did you make sure that the sample rate of the capture settings matched the sample rate of your audio? Normally FCE will give you a warning if they don't match, but it can't hurt to make sure.

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 when Blu-ray folder is exported from Encore CS6

I compile a project in Encore using H.264 and .wav files. The audio plays fine directly from the timeline. It also plays fine when I preview it from Encore. When I finally export it as a set of Blu-ray folders, the audio exports out of sync with the video. It is approximately 6-7 seconds ahead of the video. What am I doing incorrectly? When I mux the files into an .MKV, the video is in sync with the audio so I know the files themselves do not have different start times.
I am running with an HP Z820 with Windows 7, 64-bit OS and 16GB RAM.

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.)

Slideshow audio gets out of sync when exported to iDvd

I made a large slideshow for a 40th anniversary party. It has 244 images & 7 songs. It is 29 min 54 seconds long. When I view the slideshow in iPhoto it works fine & the last image ends right at the end of the last song.
When I exported it to iDvd, the audio gets out of sync with the video. By the end of the first song, the video is about 2 seconds ahead. By the end of the last image, the last song is cut of by about 30 to 45 seconds. I tried exporting the slideshow directly to iDvd. I also exported it as a large movie & it did the same thing.
I'm using a 17" 1.67ghz powerbook with 1.5 gigs of ram.
I'm using OS 10.4.2.
I'm using iPhoto 5.0.4
I'm using iDvd 5.0.1
The images are scanned tiffs. I also have jpegs that I shot with my canon eos digital rebel xt.
Anybody have any ideas or work-arounds?

I suggest you either use iDVD to create two slideshows or use iMovie to get all 277 images and the 8 audio tracks into one slideshow. If you use iMovie after you get the slideshow/movie put together and completed quit iMovie. Then go into the iMovie project package (Control-click and select Show Package Contents). The find your movie in the Shared Movies folder and drag it into an open iDVD menu. This allows iDVD to to the rendering of the stills and give you a sharper image. That movie file you're dragging is a reference movie so leave it where it is and just drag it into iDVD's window.
If you can live with two separate slideshow (consider it a potty break between the two) and you don't have or need the Ken Burns effect, you can get excellent results by building the slideshows with iDVD from imported stills. The sync to audio in this method works as advertised. I like to add a blank slide at the end of the slideshow so the music fades out during a blank, black slide.

AppleTV export: Audio goes out of sync on long videos

I am using Quicktime Player Pro to compress several long (30-90min) videos to watch on my other Apple products. The AV sync is perfect in my original movies (they are NTSC 29.97 DVCPRO50 with uncompressed AIFF 48KHz audio) However, when I export using any of the h264 presets (AppleTV, iPod, or iPhone) the audio becomes out of sync near the end of the video.
This seems like a bug. Is there some way to correct this?

Trim into smaller clips well under 30 minutes. Encode each separately then join them after. You can encode the clips a lot faster in MPEG Streamclip (free) and in a batch list as well.
