XF 405 output bitstream

[nilly]

In the specs for the Canon XF 405 it says the external output via the HDMI socket at 25p is 4:2:2

    Does this mean it is uncompressed 4:2:2 or ProRes 4:2:2?

It should be uncompressed.  Manual should also state if it would be either 8-bit or 10-bit.

It would not be ProRes; only very few of Canon's high end cinema cameras offer ProRes as a codec choice.

Thanks. What would be the bitrate at 3840x2160 50p 8-bit 4:2:0 and how much lower is this than 4:2:2?

[rs-eos]

That I do not know (actual bitrates of uncompressed signals).  But as a rule of thumb for 8-bit 4:2:0 vs 10-bit 4:2:2, the 8-bit variant should be around 60% less data than the 10-bit variant.  Part of that is the less bits per component, but also less color information too.

Thanks a lot

It means that it is outputting an 8 bit YCbCr 4:2:2 signal.
