Workflow - Phantom Cam & 35mm

We're putting specs together for a TV spot which will be shot 35mm & some Phantom Cam super high speed stuff, finishing 1080p23.98.

We'll offline in FCP at NTSC 23.98 (Cinema Tools rev telecine), and re-transfer film to HD at online stage. The Phantom Cam will be shot at 1920 x 1080, and we have a choice of delivery specs - TIFFs, DPX, or Quicktime. For offline, we'll need NTSC 24 quicktimes, of course, but we'll want to reconform to the original HD frames for online.

I thought we could get DPX files, use the AJA DPX to QT Translator, then export NTSC quality QTs, which could match back to the DPX files via the timecode. Good plan, eh?

To test this out, I had some DPX files rendered out of Color from a previous test, but the DPX Translator says, "Error: couldn't open file." Any idea why that would be? I read one post that said the DPX Translator only works with 4:4:4 footage. is this true? Is there some other reason 2K DPX's rendered out of Color wouldn't open in the AJA software?

I suppose we could get TIFFs, but those will not have timecode info, just frame numbers, and we'd have to create quicktimes with burn-in, and then manually prep the frames for online.

Or should we just get Uncompressed 1080 quicktimes instead of frames? Any downside to that? I suppose the 4:2:2 conversion isn't as ideal as the camera's raw format, but it's just going to finish in HD 4:2:2 anyway, so the loss would be negligible.

(We don't know what system the online will be done with, and our local Flame guy always hates it when we bring him quicktimes - gamma shift issues, etc...)

Thanks for any help!
