Linked video audio clip goes out of sync when put in timeline - why?

Learning to use Final Cut Express. Clip plays in browser with audio in time with video but as soon as clip is dragged onto timeline the audio goes out of sync. Why? Please can anyone help because its driving me mad!

You don't give any details as to FCE's settings, camera format or your workflow so I can only hazard a guess.
One of the main reasons that audio goes out of sync is because the Easy Setup audio settings do not match the camera's audio settings.
The default setting is for 16bit (48KHz) but your camera may be shooting 12bit (32KHz audio).
If this is the case you need to recapture using the 32KHz Easy Setup.

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.

Audio is/goes out of sync

Hi guys,
Brand new user to Premiere Pro CS 5.5
I took some clips off my Galaxy Nexus that I shot the other day and wanted to cut them into a short video so I imported them into Premiere.
When I play them in Premiere the audio appears to be in sync at the very beginning of the video but as it progresses through it seems to be worse and worse out of sync as it goes along. Even in a short 1 minute clip.
When I play these raw video files in something like XBMC or the standard Windows 8 media player, or even just on my phone there don't see to be any problems with the audio/video being out of sync what so ever.
I tested this out with several random clips recorded on my phone and it seems ALL of them are doing this in Premiere no matter the duration of the video.
Why is this happening and how do I prevent/correct it?
Thank you

Audio goes out of sync when I export to iDvd.

Anybody have any idea what this could be, and how to fix it?
Everything's fine on iMovie, the audio syncs up fine to the video, but in iDvd, the audio seems to have randomly shifted all across the video.
It's not all the audio, some of it is still in place (but with other sound layered over it).

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 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.)

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!

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 slowly goes out of sync over time

My capture segments are only 10-15 minutes long. However, my audio drifts out of sync and is severe at approx. 3 minutes with no dropped frames.

hi
i have exactly the same problem...
Im in really trouble with a project. I am producing a fitness dvd and the soundtrack is eating up frames in common to my video, where i try to syncronize the sound from. Its totally strange for me and i have no solution and answer why this is happening.And worst of all: no solution. The customer which - of course - is not satisfied.
I have NO clue what to do. Can anyone help?
the footage is taken from Sony HVR-V1E in HDV and the soundtrack is taken from a dedicated made CD and converted to MP3 before putted into finalcut. If i convert it to aiff instead it gives me files around 1 frame shorter than the mp3 files. "Sync Audio Capture to Video Source if Present" is on as well, like "thedirtyduo"s has.
Im lost (too)

Paste attributes prompt box (only 1st linked video & audio clip)

what is up with that box? how can I avoid this? I need to paste attributes to all 4 audio tracks and not just the 1st one!
The box reads:
Paste Attributes will only use the first video and first linked audio clip for parameters and content to be pasted. Do you wish to continue?

You'll get that warning if you copied more than one clip. The message is telling you that it will only paste the attributes of the first clip of the group you selected.
To avoid that warning, you should only copy ONE clip. After you've copied one clip you can then past the attributes of that clip to as many clips as you select.

Video and sound slightly out of sync when screen mirroring

When I start screen mirroring and play a video, then my macbook screen matches perfectly with the sound output from my stereo, but my tv is slightly delayed compared to my macbook which makes the sound and video out of sync. it is something like 1/10th or 1/20th a second, but it is extremely annoying.
Anyone has the same problem or knows how to solve this?

What format were the original items ?
What frame rate are they in the original ?
What format are they on the AppleTV (H264 video AAC audio is the most common, but there are others) ?
What is the video frame rate now ?
Most out of syncs come from an imperfect attempt to encode for AppleTV. ie. DVD frame rate is 29.97fps. Many encode this to 30fps. So the movie plays 0.1% too fast, too little for you to notice, but at the end of a 100 minute film, the audio is 6 seconds out of sync with the video. Or 3 seconds on a 45 minute TV show.
Also check the source. I'd had DVDs (Alien Resurrection) jump 10 seconds out of sync in the middle of the movie. Back to the shop for that one.

Any solutions for native soundtrack going out of sync when adding titles et

With the 6.0.4 update to iMovie06HD a problem emerged which the Apple Store Geniuses have been unable to solve, even after spending days with my computer/camera. When I add titles and transitions the native soundtrack goes out of synch. Previous versions of iMovie06 (in place this time last year) worked fine. Reloading the software didn't solve it, and the problem also exists on other computers running 6.0.4. Unfortunately going to iMovie08 is no solution as it does not allow 'export to tape', thereby offering no option for creating an HD movie. I tried in 08 making a DVD but image quality even using 'large' is not good.
Has anyone experience this? And found a solution?

If I output this sequence at 1920x 1080 no down scaling to 720 then it is in sync but the whole project is then too large to fit on a single layer Blu-ray disc this is why I have down scaled 720.
The only two factors which affect file size are bitrate and duration, specs like resolution and frame rate have no bearing.
Try using 1080 with a lower bitrate.

HELP: Audio regions get out of sync when I change tempo

I've got Logic Pro 9. I've recorded audio on a few tracks, and they sound great together. When I go to change tempo (either in the transport bar or in the tempo track), the regions change in size and move around horizontally, and get out of sync as a result.
Has anyone had this problem? Why should changing the tempo of the project affect the position of the audio regions IN RELATION TO ONE ANOTHER? I want them to stay in sync after changing tempo.
Thanks in advance!

The reason they move is that logic is a bar/beat based Sequencer rather than a time based sequencer like pro tools. The regions adhere to the tempo grid and when the tempo is changed, they seemingly lengthen or shorten because the tempo shifts the bar/beat grid with respect to time--and audio regions normally Are inflexible and last for a fixed amount of time no matter what the tempo is changed to. This is an advantage when your audio is quantized musical events, but for non musical events it's a disaster because it screws up your edits.
To fix the problem, find the timelock key command and highlight all regions you don't want the tempo change to affect. after selecting them all, timelock them with this command.
But, from your post Im guessing that you have bigger problems than this....Timelocking regions will only prevent region starts from shifting around and will leave all your edits unchanged. but it won't speed or slow down your audio; It will not alter lengths to fit a new tempo. if your tracks are music tracks in a certain tempo and you are trying to change the tempo of your recorded audio, you must enable the flex mode on each track. For this you should read the part of the manual on the flex engine. Bear in mind that the audio quality of this ranges from ok to terrible depending on the material.
The moral of the story is that you should try to arrive at the correct tempo before recording audio tracks.

Clips are out of order when drug to Timeline

I was working with final cut pro, showing a friend how to use it and ran into a problem that has never happened when I've used it on my machine. We did log and capture, and captured the video. then I went Mark-> DV Start/Stop Detect. From there I selected the first segment and the last segment and drug them to the timeline. once in the time line they were all out of order. Usually they are placed in the time line 1 through 80 or however many there are, one after another. There is nothing else in the time line. When I drug them this time they would be arranged in all different orders. Anyone have any idea whats going on with this?
Thanks in advance.
TY

It goes by the Track # field, as seen in on a list in iTunes. So, make sure the Track # field is correctly entered for each song when you review the album on a list in iTunes. Also, make sure the Album field is entered identically for all the songs on the album.
You can edit those fields by doing a Get Info on a song, and going to the Info windows's Info tab,

MP4 clips out of sync when dropping onto my timeline and I can't fix it.

I'm trying to drop some mp4 clips onto my timeline in CS6 Premier Pro. The problem is the audio keeps going out of sync. It plays fine elsewhere but for some reason doesn't sync up properly in the timeline and I can't fix it. It looks like the video is slower than the audio/ the audio is quicker. When the clip is on the timeline it has a green line above it where as everything that is in sync has a yellow line. All clips have been imported from my internal drive. I'm using a Macbook Pro 2.4GHz dual-core Intel Core i5. Does anyone know how to fix this?

What is the source of your clips, and do they possibly use a Variable Frame Rate instead of a Constant Frame Rate?

Audio locked at playhead, but goes out of sync if video is cropped

Hi,
Using iMovie HD 6, I have the audio locked at playhead, but if I crop part of the video (beginning or ending), the audio goes out of sync.
Here's what I've done:
1) Extracted audio from video
2) Silenced this audio
3) Imported audio from audio recorder (Edirol R-09HR)
4) Synced the imported audio
*5) Attempted to crop part of the video footage in the timeline... goes out of sync
How do I keep the audio in sync when cropping video?
Thanks!

Hi JohnDoe2009 - firstly, extracting the audio is not necessary in your case. Simply mute the video's audio, by reducing its level to zero - that is what actually happens when you extract the audio, after all.
It is my experience also, that locking audio clips to particular video clips is not fail-safe if further cropping is done afterwards, especially if that cropping is fairly substantial. Where possible, do the syncing after all crop-editing has been completed.
As a last check I always review the syncing before finalising the movie.
