PPro CS2 Audio Sync Issue

Jun 24, 2012 7:53 AM

I have a clip in the timeline.

I unlinked. Then attempted to use Alt + . and  Alt + ,   - I was unable to perfectly sync.

 

The clip is twenty five minutes.  The out of sync begins around fifteen minutes. Then ever so slightly the audio slips out of sync with the speaker. Thus its not that the whole clip is out of sych, rather, the last half of the clip slips out of sync.

Is there an obvious fix that I am missing? Thanks!

    It sounds like you have a case of dynamic OOS (Out Of Sync), i.e. the OOS drifts over time.

     

    That can be caused by several things, and testing to narrow down the cause is the best course of action, but in the meantime, this ARTICLE might be helpful to getting the Project done.

     

    Good luck,

     

    Hunt

    If this is correct from our archives captured into Premiere Pro 2 from the digital camera -an analog film lecture.

     

    Thanks

    Here's a sample... is this OOS or simply film fatigue?

    I keep looking and it feels almost out of sync. After repeated

    looking it almost feels as though the audio is synching....
