I couldn't resist playing around with Steve's Star Wars footage a bit. The clips were color corrected and downsampled to 720x480.

I'm going to be taking another look at the CineFrame 24. We shot my short film yesterday (Sunday) in CF 24 and it looked great. I'm going to capture it, etc., then import it into Cinema Tools in Apple and do a reverse telecine and go from there. Should work, but I'll post my results ASAP.

Also, Jon Fordham said, barring testing of course, that maybe shooting the Z1 in PAL mode with the CineFrame 25 on may work best of all, much like how Frame Mode was used on PAL XL-1 cameras while shooting 28 Days Later... Of course, testing needs to be done as soon as the Z1 comes out, so maybe we'll shoot another short in February that way and see what happens.

So, I'm starting to really think I was a bit wrong in my first thoughts on CF 24.

I just did an extraction of a resolution chart in CF24, to figure out what kind of res it's actually delivering. It's tough to tell truly, because besides the uneven motion sampling, it also "pulses" and "jitters" even on still shots. So you can't just pull a still shot out and judge the resolution, as the resolution is moving! I extracted a four-second portion of the resolution chart and made an uncompressed .AVI of it, and posted it at:

http://www.icexpo.com/FX1-CF24-Res.avi

It's a 10-megabyte file, please right-click and "save as..." so it doesn't eat up all my bandwidth.

In examining the individual frames, it groups the frames into groups of five (using a standard 3:2 pulldown scheme). Within those groups of five, it looks like there are two frames at about 425 lines of res, then two frames at about 475, and then one frame at 575 lines. Which means for vertical resolution it's lower than an XL2 or DVX, although still having higher horizontal resolution; and for vertical resolution it's not stable.

CF24 is unusable. It would be much better to shoot CF25 and slow down 4%, or shoot 60i and use something like DVFilm Maker or Graeme's filters.

Barry,

Try doing a reverse telecine with the CineFrame 24, which is something I'm going to do with some clips, if not the whole film we did yesterday, if it looks good and works well in my tests.

I posted a lengthy post in a thread here not too long ago (last couple of weeks) about reverse telecine on CF24. The results are 24 "frames" that feature uneven motion sampling -- a constantly moving object will move approximately 1/3 the distance on even frames, and the remaining 2/3 the distance on odd frames (or some similar ratio, don't remember exactly).

But the thread's here on DVInfo...

Can you post a link? Thanks for the follow-up.
