UMP 12K Recording in 6K Full Sensor?

Is there a reason why 6K only supports windowed modes and not recording using the full sensor at regular ratios like 16:9 or 2.4:1 etc?

I think that the way the 12K Sensor works is that you can downsample from the full sensor in 1/3 increments. So 12K goes down to 8K (2/3rds full sensor) and then down to 4K (1/3rd full sensor). I'm not exactly sure why for the technical reasons, but if I had to guess it has to do with the new non-bayer pattern of the pixel layout. It allows for 1/3 increments instead of 1/2 or 1/4 increments.

For the Super 16mm Mode it is 1/2 the full sensor and thus 6K for full. 4K then is 2/3rds. That would mean 2K would be 1/3rd, but they don't offer a 2K option. I think because 4K is becoming more a standard for distribution resolution and they're aiming for only future proof. If I had to guess.

It's to do with the maths on how the sensor pixels can be arranged.

They have to be in groups of four.

so 12K, 8K, 4K all divisible by 4.

6K is a straight window of the 12K (Half the sensor)

I see. Makes sense. Thanks for the info!
