    AutoSync Follies

    I have asked this question across the internet and can't seem to find anything on these AutoSync issues.

    Using MC 8.9.3 on both PC/Mac with RED HELIUM files.

    Imported the audio (BWF) and even exported MXF from Resolve 12.5.3.

    Attached image shows both RAW (AMA) and imported MXF (Resolve) and the synced bin.

    The highlighted clips shows you the time lenght of both RAW and MXF from Resolve.

    However, check the length of the synced file. Its almost 9 seconds shorter.

    And too boot, way off on sync :P

    If the files are synced, they do not exhibit this behaviour.

    Re: AutoSync Follies

    In addition to the above question, is there any documenation on how to use the Slip Perf (new option in Source Settings) in Avid?

    I was also trying the Slip Pef Film 24 workflow but cant seem to use the smart tools to move audio or video in larger time lenght.

    The Slip Perf tool moves a quarter frame at a time :(

    Re: AutoSync Follies

    AutoSync will always cut the clip to the shortest of its elements. So if your sound is shorter, then the sync'ed clip will be shorter than the original camera file.

    But it also begs a question: how do you do the synching?

    Yea this is quite dumb.

    If its not going to sync why bother creating a sub-clip at all?

    The drift cant be that bad can it?

    Its almost 20 seconds for some clips.

    Success rate using AudioSync with TC in this 2000 plus RED project is 80%.

    Not so bad now to deal with the rest :P

    I am still in awe that there are no documentation on the Slip Perf audio tab section in the Source Settings window.

    I get a read a few posts on how great this 3/4 Perf Film workflow is but nothing out there with specific steps.

    My understanding is that I can toggle to the Source but the only option is the slip left/right 1 frame which is brutal if your AutoSync TC slips to almost 20 seconds :P

    Anyone?

    Re: AutoSync Follies

    FYI

    The feature I prepped for Assembly was a complete mess.

    All thanks to Resolve and Avids awful AUTO SYNC option.

    While some files synced perfect, a good 1500 plus files didn't.

    Of course, during initial checks, I got suckered into thinking all was good.

    But after going over all the files, things were so badly out of sync I don't know what Avid MC was doing :P

    Went back to REDCINE Audio Sync and that seemed to have worked for what I've had to redo so far.
