I'm new to compression formats.
OK DVC is both a tape format and a compression format. The first part describes how you record digitally on a DV tape, The second part is how you turn full bandwidth video in a compressed form that you can record on tape or on a computer. The whole story of compression takes many paragraphs to explain including parts of the history of television. Full bandwidth digital television (SDI) is 270mbits/second, DV or DVCPRO compression is 25mbits/second. SDI is also :422 which describes how much color information is skipped as you scan (history of TV) a line DV is :411 which skips more color information (thus helping to leave some data behind) Codex are short names for encode and decode methods that transform TV pictures from on (mostly uncompressed) form to another compressed form, that can be uncompressed and displayed on Computers or on TV monitors. Sorry to ramble so there really is not real short English answer. The other issue is DV/DVCPRO is normally a 720 x 486 frame and if your animation is 640 x 480 you get really bad scaling issues. I can ask some of the animators I've worked with in the past if there is a fast and good method to get a good looking DV/DVCPRO animation.
