workflow for project with HD and SD material

Posted by Steve Ascher on February 23, 2009 at 4:20 pm

We are doing a documentary on a painter that will be b’cast on HBO in 1080i. The live action footage was shot in anamorphic 16:9 DVCAM, which we are planning to upres to 1080 with a Terenex or similar for the online. For the offline, we are editing in DV timeline.

We are using motion to do moves on the paintings (in 3d space using move behaviors). We are doing these in HD with the plan to combine these clips with the live action in a 1080 timeline in the final edit. The question is, what settings to use for the art? Should we use the preset broadcast 1080i? If so, will dragging these clips to the DV timeline for the offline edit be a problem due to reversed field order? Would it be better to work in motion in progressive (using XDCAM 1080 30P preset) and let FCP interlace later?

In a related issue, the edit bay where the moves are being done has a NEC 1920×1200 high quality LCD computer monitor but no external HD video monitor and we are using digital cinema desktop to look at the moves. There is at times an instability of motion (even after rendering the clip at highest settings) and sometimes twitter and/or a pixelated/aliased look, even for slow moves on images that are pretty big (2250×2700) where we’re not even filling the screen with the artwork.

Adding gaussian blur helps a bit but we’d really prefer not to have to blur the art.

Could this be due to the viewing setup? Or a setting in motion?

Thanks in advance for your help.

Is it a Moiré problem?

no, not moire. fine details seem almost electric (flickering on and off) as you zoom in. using blur to get rid of the edges helps that twittery thing, but makes the image duller.

That problem is much worse doing moves in SD, and seemed to be cured by going to HD, but now I’m seeing it again.

Any thoughts about first part of post re: settings?

Thanks
