Animation vs DV compression

If the footage is going to be edited twice (occaisonally three times) to quick time movies is it really necessary to use animation compression instead of DV. The problem results because these QT moives must travel from drive to drive.

By the way note t Mike Apple is offering occaisonal free training seminars to educators and university lab techs on FCP5

Not really - if you do lots of effects and grades (ie: rendering) to the edits then an uncompressed master might be a good idea, but simple DV cut edits and even putting it to DV tape and re-digitising over and over - its lossless.

Copying data (unless it gets corrupted) in DV files is lossless as far as the Video concerned.

What exactly were you told about editing with the DV codec vs Animation codec?

Anyway have a read of the LAFCPUG article:

Animation is lossless (virtually Uncompressed in RGB Colorspace).

DV is NOT lossless. DV is 5:1 (HEAVILY) Compressed. If you are applying graphics & rendering, I would use Animation files.

Yeah Joe - I think you missed my point...

I assumed from the post that Bob was already DV

DV cuts and DV to DV via firewire then there is no "generation loss" or lossless editing (the footage is already initially compressed 5:1 as you rightly point out and this way you wouldn't lose anything else)

If however Bob uses an uncompressed workflow then keeping the master sequences & copies uncompressed is a good idea.

So...

DV Workflow? Cut edits only? = DV backups, files, copies.

Uncompressed Workflow = Uncompressed backups, file, copies

DV with rendering of grades and effects? = make your decision on what else needs to be done with the footage.
