video quality

   I have noticed a slight drop in quality from my original footage to when I export it.
   I'm using Premeire 6.5 and when I export I do AVI. Now, a friend of mine told me it is because I'm importing/exporting in AVI and I should use MPEG instead. Is this true? Where can I set it to import/export in Mpeg? I didn't see it in Premeire. What settings should I have to export import to have the highest quality?
   
   Thanks

   A firewire transfer of DV is the highest quality consumer file available. Once it's on your hard drive the codec you use to edit (MS AVI in Premiere 6) handles effects and transitions but doesn't touch anything you don't change. There is evidence that other codecs, like Main Concept,Vegas and Canopus for example, are superior to Microsoft, but it doesn't show up without repeated re-encoding. MPEG, either 1 or 2, are final formats, not editing formats, and both are much more highly compressed than DV. You want to work with AVI right up to the moment you select an export format, and that decision is dependant on your use for the export, be it DVD, CD, web, email.

   Dave's right. ALWAYS use AVI (DV) for editing and manipulating. MPEG1 and 2 are used as formats for exporting once your project is completed (MPEG2 is used for DVD). Each time you change the format of your video (from AVI/DV) you are essentially losing quality because you are compressing the file format (usually below what the original was). If that's not enough reason NOT to use MPEG as an editing format, here's another. Most programs have trouble continuously working with MPEG (1 and 2). Many times (IF a NLE is compatible with working with MPEG) audio and video sync will get off track and the time taken to render and preview your footage will increase.
   
   So the bottom line...STAY with your native AVI/DV format!!! (until you are done and ready to export that is)
