HV20 in FCP6

Newsflash* You can edit HDV in Final Cut Pro 6 from the Canon HV20 camera. It comes in at 60i, though it records 24P.

If you DON'T make it 24P footage, you edit. Then you can output BACK to the HV20 ONLY BY USING PRINT TO VIDEO, and record the HDV stream as HDV.
Granted, you have to render the full sequence (called "conforming," but it's a render). Don't know the extent of the degradation.

All the same, you record back to your camera after a 10:1 to 7:1 conforming ratio. (Meaning 10 minutes of render time for 1 minute of CUTS ONLY video. Fade outs and stuff jack up the time).

So I got to thinking... what about ProRes? Well, can't do it on Print to Video.
ProRes is the near lossless codec for doing visual effects work with the HDV, and the best means of converting for true 24P after reverse telecine.

So... that's a pickle. Edit cuts only on HDV and bump out to tape, which is great for archiving frankly, and reviewing thanks to the HDMI via the camera. Wowsie!
OR_ Run through the renders with ProRes and then begin cutting, but have to render DVDs for reviewing edits. No HDMI. Boo hoo.
I'll suffer through HDV for the initial installments of CUTS ONLY. Alas, color correction, effects, transitions and all that jazz? Go to Pro Res FIRST.
