Teouble with audio becoming out of synce with video.

Hello, I'm using final cut to edit my videos but for some reason, FCP has been giving me some issues. In my work flow I often layout two long video track in the timeline, then I will chop up the top track to create transitions from the top to the bottom and vise versa. as soon I press play, it the video will start off in a slower speed almost as if the computer is overloaded, then it catches up to normal speed in about a second. This has really been driving my crazy. It also effects the way video syncronizes with audio. I can lay both video tracks on top of one another perfectly in sync with the audio, but as sometime once it get's to new scene or the video switches to another track the audio is no longer in sync with the video. sometimes I can stop the footage, then press space bar to copntine and the audio and video will be in sync. This is really weird and I was wondering if anyone has any answers for me. I'm pretty sure it's not an overload on the system because the projects are rather small, and I'm using a quad core 2.5, with 5 gig of ram. and this is my graphic card info

Thanks so much for you time.

Yes. Those that are designed to work with A/V files will work better.
Drives from G-tech and Granite Digital are worth a very close look.
However, if you have an empty drive bay in your G5, a second internal SATA drive is the better choice.
good luck.

When I trim a Video in QTpro, the video and audio become out of sync

I use mpstreamclip to export video to mov or mp4 files. When I load up on QT pro and then do some trimming, the resultant clips often have audio and video that are slightly out of sync.
Can anyone provide some guidance on what to do?
Thanks so much.

I think it is going to be a problem with the fps setting on export. If you entered 30 fps as the setting for export and you found the result had the audio getting further and further ahead of the video the longer you watched it may be that you needed to enter a frame rate of 29.97 fps to keep things in sync. I am doing similar tests on some conversions because I have had sync problems as well. I will repost when I check my current export at 29.97 fps.

Captured content: Audio is out of sync from video

When I capture video off my Panasonic AG-DV2500 into FCP 5, the audio is around 17 frames behind. Does anyone have some advise for this problem?
G5 Tower Mac OS X (10.4.8)

It's not in the monitor. In recent projects, I've corrected the audio by 17 frames, and the final export does not reveal anything different. Good thought though.

My audio becomes out of syn 7 minutes into my project once i share it

No matter how i share it quicktime,idvd,etc the audio becomes out of sync about 7 mins into the vid. The Vid is about an hour long and half of its on my internal drive the other half is on my external but it operates fine inside of imovie just doesnt work when i share my audio starts to lag please help

I've made some progress...I've been saving the footage on my external hard drive, a MyBook 2TB. I changed the scratch disc to the internal hard drive, left the settings at DV-NTSC, 48k....and 45 minutes of footage captured with audio and video perfectly synced.
So apparently my issue has to do with my external hard drive setup. The MyBook disc speed is 7200rpm, so that shouldn't be the issue. I have it hooked up to an airport extreme, hoping to eventually be able to access video clips from my laptop as well as my iMac.
I'll hardwire it to my iMac in a little while and try it again, just to see if it was the wireless setup that was causing the problems and not the drive itself.
Anyone else out there ever had similar issues with their external hard drives?

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.

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.

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

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 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?

Audio timeline out of sync with audio

I took an audio note using an iphone application called Moe's Notes. I emailed the audio as an attachment to myself. The note is in .caf format but I also generated an .aif version. I dragged the audio onto the timeline in Garageband and it plays, but I noticed that the audio is out of sync with the wave display. Also, the second part of the audio recording plays, but does not visibly show up as a waveform.
Any ideas? I resorted to Audacity to edit my audio.

trash your waveform cache and see what happens when you restart the program.

Rate Stretch audio goes out of sync when exported.

Audio, which is rate stretched using the rate stretch tool to 100.01%, plays fine in Premiere Pro CS6. However, when exported to Encore or to MPEG-2 file, the audio is no longer stretched and becomes out of sync by the end of the video. When I play the preview in Encore, the audio is out of sync. Switch back to Premiere, it is OK. Export a MPEG-2 file and author a DVD, the audio is out of sync. Go back to Premiere, it is OK. I record the audio using a TASCAM portable recorder. I have recorded and synched audio many times and this is the first time that it does not work, on two separate Premiere projects. Any ideas on how to fix this. Even better, is there a way to record audio so that it matches the video (from a Panasonic HD AVCHD camcorder) without requiring rate stretch adjustment?

Try changing the speed with right click, Speed/Duration instead of using the Rate Stretch tool.

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.

Audio goes out of sync when i open project on diff macs

i have an iMovie project created on an iMac saved to an external.
I go to open the project up on my macbook and the audio is out of sync.
I go back to my iMac with the same project and it works just fine.
I'm a bit confused because both macs use Mac OS X 10.6.4 and iMovie 8.0.6
what other differences might there be?
any input is appreciated as I'd love to work on projects while out in the field!

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.

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.
