i have some big HD videos ...how can i convert them to smaller sizes without losing much quality!!!

Click to expand...

use factory format and use avi or mp4 format and than convert your movies.

Xilisoft video converter converts between any container format.

FormatFactory is a free alternative offering same functionality.

Try some Hardware .. Black Magic design or Avermedia HD capture ..

Handbrake is the way to go. Use .MKV container if you play on PC otherwise use .MP4 (has some limitations). Here is a guide.
