I have about 100 clips that I need to manually decrease the playback rate and increase the length of each clip. Usually I would add slow down each clip by 20% thus increasing the length by 20%.
I'm doing it now manually in Sony Vegas (not pro).
Is there any way of doing it automatically for 100 clips, and not for each one of them manually. Please feel free to propose some other software than Vegas, if Vegas cannot do this.
