Hi Rafael,

Yeah agree, the most important note from David Taylor is the calculation between YUV and RGB in FCP is done thru floating point calculation. That's the key. As long your incoming and destination format can handle this, it should be alright. This is ensuring enough. I still have no idea why this is not documented. Sometimes, we just need to ask developers about the factual data. There's other misleading or half complete information spreading around that QT for windows is always 8 bit and designed that way which of course not the case. I heard such false assumption from other people who supposed to be pro. The point is sometimes we have to do a lot of check and asking around to seek such information, it will be so much easier it's documented properly.

Anyway, at least i got the answer :)

Rivai
