  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Two questions about downscaling 4K

14 bit color depth is offered on the new Panasonic HDX900 we shot one of these off against an F900 (which is I believe 10bit) a while back and the Panny pasted the Sony! which featured much higher cost. How much of an issue is color depth differences between 10bit 12bit 14bit is there any real world description of possible differences?
 
Well, A-to-D bit depth governs how many code levels are used to describe brightness. This relates to dynamic range and to noise levels. You don't want to be in the situation where your a-to-d quantisation noise is greater than your sensor noise, as then you'll loose information and dynamic range. But similarly, there's not much point having many more bits (ie smaller quantisation noise) than the noise floor of the sensor. It's best to record 1 bit of noise, but I don't see much advantage in recording more than that.

So, what would you see - would mostly be in noise levels and dynamic range.
