Thanks a lot Dan,
but I did not fully understand your answer.
Where do you find “adjust time by” and “source frame” are these expression elements ?
In the meantime I could solve the problem by dividing by 8 (which is the framerate of the comp):
expression on timewarp parameter:
thisComp.layer(“CONTROLS”).effect(“Einstellungen für Schieberegler”)(“Schieberegler”)/8
kind regards
