I posted a while back about some render issues I was having. Whenever I send my graded sequence back to FCP, 1 or 2 or even up to 5 clips are corrupt. I can't open them in quicktime and they show up as offline in FCP. There are no effects applied to the clips in FCP. I then have to delete the render clips manually in the color render folder, then re-render the bad clips in color. When I render the clips a second time they are fine. I then either re-link the clips in FCP or do another "send to FCP" in color.
I am using ProresHQ 29.97 1080i with progressive footage from HDCAM.
This has been happening consistently for a few weeks now on a bunch of different shows, although once in a while I will do one with no problems.
Could it be something at an OS or hardware level? I am rendering to a terrablock partition through fibre.
I am on Tiger 10.4.11 and FCP 6.03 with latest v of color.
Anybody else seeing this?

Why are you using 1080i with progressive footage from HDCAM? You should be in a progressive setup. That could very likely be the culprit. I've never seen the behavior you're describing.

Why 1080i? My footage is 29.97 PSF, not 23.98 or 24. I am going back out to 1080i 29.97 HDCAM for mastering and I have a few interlaced graphics in the show. Are you saying It's not a good idea to send a 1080i sequence to color even if the media is progressive? I know there are issues in Color with actual interlaced footage but this stuff is PSF.
The way I have always understood that in camera progressive 29.97 HDCAM is actually interlaced but field one and two are the same, resulting in a progressive look. I have always used 1080i sequences with PSF HDCAM footage for many episodes of several different shows, both in Avid and FCP with no major issues other than this. I have never even used a progressive sequence - All the 1080P Kona presets are either 23.98 or 24 FPS.
I don't this is the issue since 98 % of the renders are fine.
I stand to be corrected if I am wrong on any of this though...
