    Pluraleyes with 2-camera HD shoot with 1-2 frames drift?

    Has anyone used Pluraleyes with a 2-camera HD shoot where the cameras and the sound recorded (separately, in addition to audio on the cameras) may have a 1-2 frame drift over 5-10 minutes?

    The cameras did not have lockboxes/genlock.  Sometimes 2 Canon 5D's were used, sometimes one Canon 5D with one Sony F3.

    Not all media drifts 1-2 frames out over 5-10 minutes, but some does.

    We are going to fix the sync and make group clips and I heard about Pluraleyes as a possible fix.

    Would this work for our needs?

    Thanks in advance for your reply!

    Sounds like 23.976 vs 24.000 issues. Notsure how PluralEyes would help.

    A 23.976 vs 24.000 issue would produce a 1% sync drift over time.

     

    What I am experiencing is smaller than that.  I know that a lockbox/genlock was not used on the shoot.  The cameras are close to running in perfect sync, but without the lockbox/genlock, they are drifting 1-2 frames over 5-10 minutes from a start clapper slate.

     

    A 1% drift over 5 minutes would be about 3 seconds.  This is a much smaller sync drift issue.

     

    Just wondering if anyone has used Pluraleyes with files that drift away from each other ever so slightly.

    IIRC, Pluraleyes will sync to the center of the clip allowing the head and tail to drift.

    I am a little confused. Is Pluraleyes introducing the drift or is the drift from the actual recording?
