We have set aside some time in rehearsals to test 444/422 HQ,LT and proxy.

At the moment it is three screens with unique content on each. So 1920x1200.

The designer is keen to work in RED raw format and then downsize on the final export to 1080. It may well turn out that with his hardware setup this is not possible. We shall see.

In terms of capture size vs output size I have heard that downsizing from a larger resolution still looks better than capturing at the final output size? I have yet to see this for myself....

Also there have been questions asked about what bit depth catalyst can handle/process? Im not really sure how and where this comes into it. Does the projector not have the final bottleneck in bit depth?
