Tutorial 1: Constant offset between picture and sound

A word before

The correcting of divergences between picture and sound is pure manual work, and no serious program in the world would offer a "one click automatic" to solve such problems. In the professional area there are different time codes which should guarantee the correspondence of picture and tone. But also these fail due to the absence of an universal "synchronous run management" at the latest if there are uncalibrated components which delay the video and the audio signal differently (see the introductory example digital television).

It's a question of your own discretion when you accept picture and sound as synchronous, and depends among other things on your sense of hearing, on your time feeling and on your quality claims. Therefore, there can be no "resolution" of the tutorial projects, like "right" or "wrong" correction values. Compare your results not too rigid with ours.

Our solution suggestion

As described in the tutorial, we have defined a spline marker at the 61st frame (the first hammer blow) and adjusted the sound by means of its correction offset. With a value of 11, we liked the synchronous run best of all.
