Also, when I speed up video footage (I've been trying to make speed art videos) it freezes every few seconds then plays again but again, once it's saved as a full movie it plays perfectly, it's just hard to edit with it like this :/
Please could you suggest how I could stop this/any software that definitely won't do this.
Thanks x

Btw I put this in four sections because I couldn't work out which section to put it in :/ Sorry, I've deleted them now...

I have a Dell XPS L521X, with a Intel Core i5-3210M CPU @2.50 GHz, 8GB RAM, and a 64-bit Operating System. I have over half the space left on the disk and it's never been slow until now...
