Shoot HD or SD with the XDCAM?
on Sep 15, 2006 at 6:06:21 pm

We have a shoot for a TV commercial coming up, and we are using the Sony XDCAM PDW 350 @ 24p. The final output of the commercial will be SD, as well as edited on an SD NLE system. Would it be better to actually shoot in standard definition and edit that way? Or to shoot in HD and downconvert to SD using the PDW F70 deck? Are the results any different?

Yes. If you shoot HD and downconvert correctly (to the correct format), you wind up with color resolution much better than 4:1:1, which is what you'd get if you shot DV25 mode on the F350.

The act of resizing a 1080p frame down in software (if done with care), nets a frame with much less compression artifacts and better color res.

The downside of course being that it's a pain in the butt to do all this

How about just outputting from the SD/SDI output into our 844/x system. Is the down-conversion in the PDW-F70 deck as good as software?

Sorry, missed the part about the deck. I would think the SD/SDI output of the deck would NOT be decimated to 4:1:1, so yes, if that's true, it would be a good way. Just watch the detail setting on the SD output of the deck...there should be Low/Mid/High setting for that.

The SD output of the cameras is either DV 4:1:1 or composite, so that's what I was recommending against.
