Thanks all, for the historical tidbits.

OK, if Apple means by “32 bit color” 24 bit R,G,B color plus an 8 bit alpha channel, I have some questions.
Doesn’t 10 bit uncompressed 4:2:2 video, which has 10 bits for each of Y, U, and V, produce better color (or more colors) than 32 bit color?
Alpha masks are only used in effects. Why is codec “None” offering 8 bits per pixel for alpha masking when almost no video has alpha masking? And why doesn’t codec “None” offer standard 1 bit alpha masking?
Video is normally coded Y,U,V, which makes subsampling so efficient. Perhaps codec “None” videos can’t be subsampled. Are all the other codec “None” depth settings coding R,G,B? This matters, since 24 bit depth distributed 8 to each of R,G,B yields different colors (though the same number) than 24 bit depth distributed 8 to each of Y,U,V does.

I expected Apple codec “None” to be something fundamental. From the details in the original post, it seems something amateurish and screwy.

Thanks.

Yes, it would be hard for an external drive to send it fast enough. I did copy the .mov to the desktop. The machine on which I attempted to play it was the same machine that created it. FCP, if not FCS, was installed on the machine.
I’ve now watched a guy succeed to play it by dragging it into FCP. He calls FCP an maturer Quicktime.
I now fear that the source of my troubles is that I’m running FCP5 on a Mac Pro. I’m reading that FCP5 doesn’t run on the Intel processor. Well mine does run, but flakily. It is less finicky than FCP4 was on my G4, so I was half-satisfied, but now seeing the other guy’s FCP6 running solidly on a Mac Pro, I know there is a problem.

Either with the big file on a Firewire 800 hard drive or on the Mac Pro’s hard drive, I wanted go preview it with an HT-1100 projector (operating as monitor #1 for the Mac Pro). Since the work is only for projection, not for monitor presentation, this seemed a better demo. I find that using sRGB settings on both, and then decreasing projector’s brightness a bit while increasing projector’s contrast a bit makes fine projection. But I found this out only for a 2.4 GB H.264 Quicktime export — the one that I was able to play.

I can add some detail to the previous post. My Quicktime movie utilized Big Endian sound, and uncompressed 10-bit 4:2:2 720×576 picture with millions (of colors). It is still regarded as DV-PAL format, I believe. Why shouldn’t Quicktime play it? Why does Quicktime say additional software is required, maybe from the Quicktime components page? Everything I’ve done is Intra-Apple.
