Best Output File for Video?

Question

What is the best Output File for making a Movie.

Answer 1

Depends on how you want to play it.

If you want to play it on your DVD player, the dvd format.

If your DVD player supports DIVX, that is good to use.

If you just want a compressed file to play on your computer, use AVI. It is the most popular anyways.

Answer 2

It depends on what you want to do with it, but you'll have the best quality by leaving it in its original format.  Only convert to the final format, be it MPEG-2, some flavour of MPEG-4, wmv or whatever at the end of your workflow.
