  Out of sync sources

  Posted by Jon Felix on May 7, 2013 at 5:49 pm

  I may be missing something obvious here, but I’m wondering if there’s a quick fix to my problem. I’m cutting a feature and have been provided with transcoded and synced dailies. Problem is that every clip is out of sync. The sound is always 2-3 frames early. This is human error: someone not understanding the use of a good old fashioned clapperboard.

  Obviously there are several ways to fix this in the timeline – easiest being to unlink each shot – slip the audio – and re-link. Of course Premiere now tells you that the shot is out of sync, and I regard this solution as clumsy and potentially confusing when the film is handed to the sound editor.

  I am wondering if there is a simple way I can get each clip re-synced before I edit with it. Short of putting each clip into a sequence, re-syncing and creating a new source clip.

  Thankyou,

  https://wjwoodrow.wordpress.com/2013/02/04/correcting-for-audiovideo-sync-issues-with-the-ffmpeg-programs-itsoffset-switch/ I would probably batch the files in FFMPEG.

  Creating a batch file with filenames seems less cumbersome and prone to errors than slipping and re-encoding in Premiere.

  This is, of course, assuming that offset is consistent.

  Instead of re-linking, you can also just use the group function; the latter will not show the offset warning. The downside is that both methods only create an altered file on the timeline, every time you pull a clip out of the bin you have to fix it. You cannot merge clips if the video and audio are completely from the same source.

  I suggest the following: sync dailies to production audio with Plural Eyes, unlink and delete the dailies audio, fix the slight offset with the production audio and the clapper, merge daily video with production audio. It’s the least time consuming method that comes to mind besides resyncing and rendering an entire set of dailies. Anything less I feel would slow you down in ways you don’t anticipate.
