Thanks for the reply. I am pressing Queue, and am being correctly sent to Media Encoder. However, once there, I do not see any option for ProRes.
Here is the dialogue box when I press export in Premiere, including the settings I would like to use.

Here is the Adobe Media Encoder window that appears after I press Queue.

I couldn’t take a screenshot with the drop-down menus selected, but under Format I am limited to F4V, FLV, H.264, H.264 (Legacy), and MP3. With F4V selected, I have a number of presets available (including various “Match Source Attributes”, Mobile, PC & TV, Phone & Tablet, and Web options). H.264 gives all of the standard device and web output options. Obviously, neither Flash, H.264, nor MP3 formats will give me the ProRes preset that I need.
As you can see in the upper right panel, when I search “prores”, no presets appear.
Just to reiterate, Premiere recognizes that I have ProRes available as a codec, and exports my footage as ProRes just fine. The issue is that Media Encoder doesn’t give me that option. Unless I am missing something? Thanks again.
