Yes, Handbrake comes in handy in many different situations. Rather than importing those files into iMovie or something of the sort, and exporting them as a Quicktime file, you can choose your "Source" to be one of those AVI files and easily choose all your settings for a Quicktime export. It's that easy!
im wondering with Handbrake can you have multiple AVI's in a queue for processing or is it just one at a time...i cant seem to get the multiple queues like with iSquint.
