Right. Sorry for the confusion. This is actually an mov clip (320x240) I downloaded (with signed clearances) from the net. I've been using either quicktime, or mpeg clips. Some of them, I can't get a higher resolution (720x480), so to get the best possible quality with them, I was told to use Mpeg Streamclip or Compressor (which I have with FCP studio). Which one will deliver the most?
Your help is greatly appreciated on this matter.
I've never had to use Compressor before, and since I'm not naturally technical, would have to learn it. Is it worth the time, because Mpeg Streamclip is pretty much automatic, though it was a free download. Does that make it not as effective/powerful?
