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 Video out of sync after Capture

I've read thru the Discussions posted but can't seem to find the exact same problem....
This has happened in both FCP5 and FCP6..
Last nite I captured wedding video into FCP6 from 2 identical cams with identical settings..The 1st Capture (18:00) went OK but the 2nd Capture of the same duration showed a window and transport bar. It stated something to the extent "analyzing audio". It's done this in the past and every time it occurs the audio is exactly 30frames off. The video precedes the audio by 1 second. It's easy to re-sync the two but annoying when it happens.
I'm capturing both videos into the same document so no settings change and the problem is not specific to just one camera. It has happened on both cams. I'm using the same tape deck to capture both videos and the same mini-DV tape brand.
Anyone have any thoughts?
Thanks

To nomadesign: I've not tried that. I use the tape deck to reduce wear on the heads of the camera. If I knew which clips would have this prob then I could use the cam which originally shot the vid. I guess I could go back and re-capture the footage which slipped out of sync using the cam which shot it just for a test.
To 2reverb: the video was captured at 48khz. When I first got the cams they were default set to (is it 34 or 36khz) and i discovered the prob very rapidly so I corrected the cams right then.
Thanks to both of you!!!!

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.

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 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
Go to http://forums.adobe.com/community/premiere and, in the area just under Ask a Question, type in

Canon HDXL1 Sound out of sync after capture in HD when shot at 24Frames

When shooting with the new Canon HDXL1 in HD with the frame rate set at 24Frames, the audio is way out of sync when captured in FCP using the apple Intermediate codec and HDV firewire. If I play it through the camera to a HD moniter via compnent cables, the sound is in sync. The lag only occurs when capturing in FCP. Any answers? I have been told that Apple may address this issue on their next FCP update. Am I doing something wrong?

The audio default for the Canon XLH1 for HD is 48khz.
In the HD 24F mode the camera records in 24fps progressive mode. During playback the signals are down converted to 60 fps interlaced using the 2:3 pulldown method.
While recording, if the HDV/DV terminal is set to HDV output, the output signal will be in 24 fps progressive. The signal output from the HD/SDI terminal and the component out terminal will be down-converted to 6ofps using the 2:3 pulldown method. Mayber I need to use tools>remove advanced pulldown in FCP on the clips?
Thanks for your reply

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.

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 and video out of sync after capture from Canon

Help for a newbie please? I have a Canon XHA1S and have a problem after capturing HD video. After capturing a 40 minute clip, the audio and video are out of sync. Seems like there is about a 3 second difference. The entire clip is like that in the source window; I made a couple of quick edits and have the same problem in the program window. Tried exiting and re-opening PP, but that didn't help. I'm running PP in CS6 on an iMac 3.4 GHz i7 with 8G of ram. Thanks!

I have NOT used it, but many say to try this for HDV capture http://strony.aster.pl/paviko/hdvsplit.htm

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 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.

Out of sync after capture

For the life of me I can't figure this out.
I'm capturing DV footage shot at 24pa onto a 23.98 timeline - pulldown removed.
The setting on both camera and timeline are 48KHz and 16bit.
In the timeline the audio is waay out of sync. The raw file plays perfectly though.
This has never happened to me before anyone else?

I have to resurrect this old answered thread because unfortunately it's not answered. I had to put this project aside and now I'm back at it.
It's not the camera. I've got 8 tapes in this project and 5 are out of sync.
Like I said the raw files are in sync and if I export a self contained file it's also in sync.
Weird.
I've trashed prefs and am stumped as to what else to do.
All settings are correct and I always use these settings on sd projects and all other projects are working ok.
Any other ideas?
Thanks

Audio falls out of Sync after a few hours

Here's my problem... After weeks of trying to get FME and FMS
to work correctly, I finally got everything talking to each other
once I installed FMS on a different server than FME and Apache, it
now works great.
What I doing is capturing our stations live feed from an ATI
PCIE TV-Tuner, Encoding it with FME which is feeding it to a
Windows 2003 Enterprise Server running FMS Ineteractive, then feed
to an Apache server on the same machine the FME is running from.
After 2-3 hours of encoding it falls out of sync, the longer
it encodes the more if falls out of sync. How can I resolve this
problem?
And one last thing... I'm using a modified version of the "
LIVE" example application.
The Encoding Machines Specs are:
Windows Vista Enterprise
AMD Phenom 9600 Quad-Core
8 gigs Memory
The FMS Specs are
Pentium HT 3.8ghz
6 gigs memory,
Windows 2003 Server Enterprise

Which version of FME are you using? is it the latest version
(2.5) ?

Audio gets out of sync after export and burn to iDVD - works in iMovie

I've burned my DVD show twice on iMovie and iDVD and the audio music tracks slowly get displaced over the course of the show (15 min) after exporting and burning to iDVD. It gets pushed back so that it starts later each new track...I've locked the audio to the playhead for each new audio track - however, there are some empty gaps between the tracks, does this have anything to do with the displacement? Or should it not matter since the tracks are locked?
I had it all synced up in the playback on iMovie and had it aligned with visuals, however, after burning, it gets displaced and everything gets off...
Any help would be appreciated, thank you
Chris

Audio/video out of sync after export

My son Charley and I are working on a simple project, where we have imported an MP4 file into Premiere Pro, then edited it, with no problems, but when he exports the file (either to an MP4 or FLV), there is a small but noticeable audio-video sync problem on the exported file. There does not seem to be a sync or other problem with the source file, nor with the edited file as viewed within PP. But on the exported file, the audio seems to run slightly ahead of the video.
When we upload one of these exported files to Youtube or Vimeo, the sync problem seems to become more noticeable than in viewing the exported flv or mp4.
We cannot find a solution in searching the Forums. Charley consulted with another more experienced videographer, and they tried for hours to no avail.
Charley is using Premiere Pro CS5.5 on a Mac (MBP Mid-2009 2.53 Ghz Intel Core 2 Duo, using OSX 10.6.8).
We see lots of discussion about frame rate. Charley put the settings to 'match source' but maybe there is something else we're supposed to do.
He can post screen shots of all the settings, if that will help. Adobe provides no phone support for PP and just sends us back to this Forum.
Any help much appreciated.
Michael Lanning

Kevin: OK, that's helpful. Charley is at work until 3:15 Eastern; in the meanwhile, I'm trying below to reply to your inputs; sorry if some of my questions are illogical, just reflecting my confusion.
You say to match source settings, including audio sample rate, and (I think) that we should do that by creating a new sequence at which time we select the clip and drag it to New Item button. Perhaps doing that would make some of the following questions irrelevant, I'm not sure, but here they are:
We did not check the box "Match Sequence Settings" (just under 'Export Settings'); should we have done so?
On Presets, and using FLV vs H.264:
Do we need to leave the 'Match Sequence Settings' box Unchecked if we want to use a YT or Vimeo Preset?
FLV does not seem to have a pre-set for YT or Vimeo, but does have one for 'Web.' H.264 does have YT and Vimeo pre-sets. As I've mentioned, we have been trying to make this work with FLV, as Charley found that H.264 was giving us (worse) sync problems. Maybe we should go back to H.264.
You say that "if these things don't work, "...try an similar H.264 preset to upload to" YT. Do you mean to suggest that we try exporting in H.264 instead of FLV? (If that's not what you mean, and if we still work with FLV, then I don't know what "an similar H.264 preset" would be; do you mean like the 'Web' preset?
Whether FLV or H.264, I'm unclear how ensure audio sample rate matches source.
Codecs listed on source file are H.264, AAC; does that imply that under 'Basic Audio Settings' on Audio settings tab, we should use an AAC codec rather than the MP3 now indicated?
Should we be determining the bitrate settings of the source (ie, right click the file within PP to find the properties, including bitrate?) and then using that bitrate?
Or do we resolve all this about audio sample rate simply by creating a new sequence as discussed above?
I hope these questions make sense. Thanks again for your help.
