I've been wanting to play reverse clips in my movies but haven't found any programs that could do that. Any help would be awesome.

What editing software do you use??
I know in Premiere, you just go to video speed and then write -100%.

I'm sure any program that allows you to change the speed of the clip would allow you to do the same.

Yeah, I use Premiere (version 6 i think...) But I've never actually used it for a whole movie. Just messed around with it. Thank you SO much for the answer!
