capturing from tape, my initial capture was PR4444.
that proved too hard for the CPU, resulting in many dropped frames,
so i've recaptured as 10-bitRGB.
I have to bust it up into smaller parts, so i figured i;d transcode to 4444 as i do that.
but the files i create doing that behave strangely:
when i put them into a sequence and say YES, i want the sequence to match the clips,
i still get a green render bar.
i can't see ANY properties that don't match,
the clips have NO attributes on them (motion effects, filters, etc)
when i change my sequence from "render in 10bit YUV" to "render in 8bit YUV", or "render in RGB"
the render line changes from green to the blue/grey of "full"
now, the original 4444 captures sit in a timeline just fine,
but even if i i export from these clips, there are issues:
Batch Exported files get the green line in a timeline,
a MANUAL export reveals something odd: i don't get the "item settings" option in the export window,
i get the Apple Intermediate option as the default,
I've seen that when the clip you want to export is non-standard.
