    Anyone know the match calculation for audio stretch? Which speed for an exact "Fram per second"?

  3. If 25 is 100%, then 23.976 is how many percent? This is a simple proportion.

    25 : 100 = 23.976 : x
    x = 23.976 * 100 / 25 = 95.904

    If I'm understanding you correctly, then johns0 is correct and you're wrong. To match a 23.976fps video, audio from a PAL 25fps source has to be lengthened, not shortened.

    It depends how how the multiplier is used,for the speed change can be 95.904 for slowing it one way where the other way is for change speed to be applied by percentage.
