I've managed to create a link to my second YouTube channel in Premiere Pro but when I try to select it in the Media Encoder dropdown it won't let me upload to anything other than the original channel. Even though the second channel is shown in the dropdown, the first channel remains stubbornly ticked! Any suggestions as to how I can pick the other channel for my upload? Thanks.
I'll move this to the Media Encoder forum.
