Video editing software for automatic movie cut and watermark NEEDED
 

Hi guys, looking for some video editing software which allows you to import full lenght movie (for example 20 minutes), randomly shorten (to 5 minutes) and put watermark in the movie. Do you know about anything suitable? Actually I cut and watermark my sample clips with Windows Movie Maker, but its not possible to do it automatically and there is no batch cue to convert prepared movies for example during night...

I think the way is to use Adobe Premiere with scripts, but its too difficult for me to set it up. Any ideas, guys? Thanks a lot!
