Under Prospect 4k, I am only able to locate Cineform AVI and Cineform MOV under the Media Encoder dialog box. It used to be under the File > Export. Does this work fine under Media Encoder or is this a bug and it should still be found under file > export?

i thought this too no separate video export on cs4 - see my post earlier, but there is another one under there if you select AVI or microsoft avi i think, then use the cineform codec, you can select medium/high/film scan and 444 colorspace etc..

This is a CS4 change, that is where it is now supposed to be.
