[Rivai Chen] "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. "
No, this is not alright, but it seems that is the only chance.
You don't go RGB>YUV>RGB, when you can stay in RGB all the way through.

[Rivai Chen] "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."
Analog was more difficult to manage, but everything was standard. Everything was in the books.
In NL digital, everything (Applications, codecs) are proprietary. They do whatever they want inside their software and they don't have to document it.
Professional Third Part developers complains that they are absolutely lost about many internal processes in FC.
Some says that Apple do not disclose documents because there are too may internal tricks and substandard processes used to overcome the FC and QT shortcomings.
