Fujifilm says "..the X-H2S produces its 6.2K and 4K up to 30p from 14-bit readout, rather than 12-bit mode on previous cameras, meaning the camera can detail up to an extra 2 stops of dynamic range in video mode."
and. "Despite the higher bit-depth of the 30p (and slower) modes, Fujifilm says the X-H2S offers rolling shutter rates of around 10.6ms in F-Log 2 mode, quicker than the 16.6ms rate of the X-T4. The higher frame-rate modes, or use of the original F-Log profile, see the camera use a 12-bit readout mode, delivering rolling shutter of 5.6ms."
I don't quite understand...
1. does this mean all Flog '1' only uses 12 bit sensor readout, even at lower shutter speeds?
2. presumably having higher frame rates than 30p mean you only have 12bit sensor readout...so does it then improve the sensor readout speed and rolling shutter?
and then subsequently, 3. If flog2 is used above 30p, and it does convert to 12-bit sensor readout, does it lose the '14 stops' of dynamic range?
If anyone knows it would be really helpful
