I did a multi cam shoot over Christmas 2011 using 2 Canon XL2's and a Canon XLH1 (the HD version of the XL2) I did not record audio because the venue audio engineer was doing a "LIVE" recording and gave me the uncompressed WAV file 3 weeks ago.</p> <p><strong>The PROBLEM:</strong> My video sequence begins to lag the audio after only a minute into the edit.</p> <p>The EDIT: I took my video and did a multi cam sequence in FCP 7. All matched-up perfectly. Then I took the supplied audio track and matched it up to the video at the In Points. All looks good for the first 20-30 seconds, then the video begins to lag the audio just a little at first and then progressively getting worse.</p> <p>If I create a short 1 minute Quicktime file, it's even worse. </p> <p>Any suggestions would be of great help and I can supply more details.</p> <p>Finally, yes, I know that in the multi cam sequence, I can use the audio file as a audio track and switch between the camera views but that too gave me the same "audio-lagging video" problem I described above.</p> <p>PLEASE HELP!!! I've gotten more than 40 hours of work in the post-edit and I'm no closer to being done than when I started.</p> <p>Thanks,</p> <p>VideoDave</p> http://www.videomaker.com/community/forums/topic/audio-out-of-sync-when-exporting-from-premiere#post-69421 Wed, 13 Jul 2011 12:30:32 +0000 fracolon 69421@http://www.videomaker.com/community/forums/ <p>After importing and syncing audio from Camera and Audio device into sequence everything is fine...but once I export into quicktime and review the exported video I notice that it is out of sync by as much as 3 seconds....but when I review in the Premiere sequence it fine...</p> <p>Using Premiere Pro CS3....and clues</p> http://www.videomaker.com/community/forums/topic/sync-help#post-65498 Sun, 13 Feb 2011 05:11:19 +0000 Larry 65498@http://www.videomaker.com/community/forums/ <p> When I film and record the sound on a Roland vs 2480 then transfer it to Cube base I get a faster tempo .  Some one said Camera is in 48000 and roland was in 44000  Is this why the clock is different.  </p> http://www.videomaker.com/community/forums/topic/audio-not-in-sync-with-video#post-53770 Wed, 06 Jan 2010 08:39:48 +0000 asadovnikov 53770@http://www.videomaker.com/community/forums/ <p> I have been using Adobe Premier Pro CS4 for a few months for a number of small/big projects and it worked fine. However, in the last two projects I faced a strange problem: audio lags video. </p> <p>1) I captured 1hour HD material form SONY FX1000 in to PP CS4 as usual.  I checked MPEG file using Windows Media Player and there was perfect sync between audio and video. Then I imported this file as an asset into PP and watched it there. The beginning of the file is O.K., but at the end audio lags video by ~1s. Same problem was in MPEG2 file after encoding. I tried to re-capture the file - no effect. Becasue editing was quite simple, I managed to correct this problem by settting audio speed = 100.025%?</p> <p>2) Second example was much worse. I have compressed 1hour MPEG2 file. It works O.K. in WMPlayer. I imported it into PP and found complete de-sync between audio and video. Due to extremely bad quality of initial material all I can say for sure is that at the end of the clip audio lags video by ~13sec. It is difficult to say what happens at the begining but changing audio speed to match A and V at the end does not help in the middle. I by-passed the problem using different editor (Ulead media Pro) and produced required file.</p> <p>So, what is the root cause of this effect? I admit, just before the first project I made extensive cleaning of Adobe files that littered my computer. Looks like I either deleted some important file or made un-intentional change to PP settings. I did not try re-installing PP CS4 yet. Any other ideas?</p> http://www.videomaker.com/community/forums/topic/improperly-indexed-footage#post-54915 Mon, 08 Feb 2010 00:29:50 +0000 bprost 54915@http://www.videomaker.com/community/forums/ <p>Hey everyone,</p> <p>Recently I deleted all the temporary render files in my premiere pro media cache folder to free up space on my mac hard drive. This unfortunate action somehow prevented me from opening my premiere project file. I have wiped my entire drive and reinstalled the creative suite to try and get it open, and now I am able to get my project file open, but everything has been somehow corrupted.</p> <p> </p> <p><strong>So here's my problem...</strong> I believe that the premiere is unable to read the footage file's timecode because all my edits are out of sync, both the audio and the video. The sequences are all still put together properly, every shot and every audio clip is the right length and in the right place, but it's drawing the source from the wrong point on the captured tape. So to illustrate, as I play a sequence, not only is it playing audio from earlier or later on the tape than the point I specified, but the video is coming from the wrong point as well. The audio and video are not even from the same incorrect place on the tape! I've examined the footage in the source monitor and have discovered that although the audio and video are initially in sync, they slip out of sync as the clip goes along. I assume this is part of the problem, and it's one I've read about, but it isn't manifesting in the timeline in any way I am familiar with.</p> <p> </p> <p><strong>I have tried</strong> importing the footage in a new project file and have had the same problem. I have tried selecting "replace footage" in my initial project file to no avail. I have also tried opening various older versions and backups of my project and have had the same problem. The issue is clearly with the captured footage and premiere's ability to properly index it. When I deleted the render files, I must have deleted something that premiere creates when you capture footage that it needs to getting everything to sync up.</p> <p> </p> <p>Can anyone think of a way I can get my project working properly again? Any help would be much appreciated.</p> <p> </p> <p><strong>My specs:</strong> I'm operating Premiere Pro CS4 on my Macbook Pro running OSX 10.6.2 Snow Leopard with 4 GB of RAM. My footage is all 1440x1080p at 24fps in mpeg format. The mpeg file plays fine outside of premiere. </p> http://www.videomaker.com/community/forums/topic/tristate-sync#post-47162 Mon, 25 May 2009 12:54:10 +0000 Ludo 47162@http://www.videomaker.com/community/forums/ <p> Hi,</p> <p>I'd like to know why we need a tristate level sync for YUV HD ?</p> <p>Thank to everybody who can help me to understand</p> <p>Regards</p> <p>Ludo</p> http://www.videomaker.com/community/forums/topic/audio-sync-issue-importing-into-ppro-cs4#post-45668 Thu, 09 Apr 2009 01:08:17 +0000 andrew2009 45668@http://www.videomaker.com/community/forums/ <p>Is there any way to re-sync or re-calibrate an audio/video file in the PPro CS4? I captured HDV footage in PPro using standard MPEG format (as per usual)... the start of the clip is fine, but the audio is out of sync in the later section (in the timeline). When I "Edit Original" or preview in Bridge the audio/video are perfectly in sync.

The Digital 8 records the entire event and I use the Mini DV to capture some close ups and different angles.  The problem I am having is trying to sync everything up when I get back to Adobe Premiere.</p> <p>I know there is something called time code and SMPTE, but I’m not sure if that is what I need to accomplish what I need to do.  If I am missing something, I would greatly appreciate any help, suggestions or links.</p> <p>Thanks in advance!</p> <p>Chaz</p> http://www.videomaker.com/community/forums/topic/avi-render-problems#post-40138 Sun, 14 Sep 2008 17:16:22 +0000 newmovies 40138@http://www.videomaker.com/community/forums/ <p>I used three camcorders to record a wedding. While editing during a song, I used the primary footage and overlayed a few places with video footage from the other cameras getting different angles of the singer for only a few seconds. While not using time code, I was able to sync the new cuts so that the audio and video are in great alignment. However... when I render to AVI the cuts were out of sync (their lips moved at different timing than the music). Any suggestions? when I rendered as a WMV file it stayed in perfect sync.

Some songs will be only acting and others will be someone singing in place of the original artist. I'm trying to find out how the process works in getting permission to use the songs in a video (I'm thinking a sync license) and permission on using the song but with someone else singing it. Any info helps and is greatly appreciated.</p> <p>Thanks</p>
