What does FCP 6 do while rendering in 10-bit YUV? Is it promoting everything to float for the FxPlug software pipeline, or something else?

Nevermind, I found an old message from this list that mentions that in fact it does.

What do other people do in this case? I have some filters that don't yet handle full float. Is it better to not support float at all (ie. 10 bit YUV) or clip?

That's a marketing decision, but if you are only supporting 8 bit, then technically you'll need to at least convert the floating point to 8 bit and then process and convert back (which I presume you were going to do). I don't think returning a black frame when presented with a floating point (10 bit YUV) image will make your users happy. Of course, when they get different bit depths out than what they put in, that will make them unhappy too (and users DO notice, trust me... We get lots of emails about our AE plugins which can only support 8 bit within FCP). Also, it's been my experience that even with 10 bit images you can be presented with 8 bit RGB. The difference seems to come into play between rendering (floating point) and clicking around the timeline (8 bit), but perhaps I am wrong on this. Paul Schneider, can you elaborate? Am I insane on this point? Pete _______________________________________________ Do not post admin requests to the list. They will be ignored.
