Converting AVI to MPEG2 for editing

   Is there any downside to converting large avi files to mpeg2 for editing? The final project is going to be in mpeg2, to make a dvd. My hard drive is running out of space. I have about 5 hours of avi footage, at approx 13 gigs per hours. If I convert that all down to mpeg2, it will only take up about 7 to 10 gigs total.

   If video quality is important to you, then simply buy more hard -drives, They're cheap. You can get an 80-gig hard drive for $70.00. If you consider that MPEG-2 is compression, you'll be starting with video which already has a quality degradation compared to DV. Not many software packages handle MPEG-2 editing gracefully because of the need to decode and then re-encode the edited video back to the compressed domain every time you make an edit. When you render the edited output as MPEG-2, you'll be creating in effect '2nd generation' re-compressed video. The quality loss could be unacceptable. If this is your only option, I recommend that you try a little clip first, to see if this is really a viable solution, compared to increasing your storage space.

   YES
   
   1) Lower video quality
   2) Slower editing
   3) Poor ability to edit MPEG2 files (most recommend converting them to AVI's first)
