Hi,


I have many videos, more than 100 that I would like to increase the length by a percentage, e.g. 20% longer for each one of them.

Is there any way to do this in a batch/automated way?

If it can help, I have Sony Vegas (not the pro version), but if I can achieve this with some other software it's not a problem.

I'm interested in a reliable solution since I will be using this regularly.

Many thanks
