I can't believe it! 3CCD camcorders without the rolling shutter inferiority of the CMOS ones still exist and their sensors are even bigger!

But why does that particular camera have 422 chroma? How a field news-gathering camera designed for gathering news on the field would benefit from 422? Doesn't the consumers watch TV in 420 anyway?

I thought 4 44/22 was good for green screen applications and movie making. Why would some news van people need it?

As far as I understand, before broadcasting, your signal will be converted and changed which leads to further loss. So by providing 422, the broadcasting company has more leeway to convert/compress.

See Why is the “broadcast standard” 422 and should we be concerned about shooting 8 bit 420?
