Can't wait joebert! Yes you can definitely post on you own channel beforehand. In fact, if there's a way to mention the collaboration, it might be a good way to generate some buzz for the show!
I'll still need a file for editing into the final mix, so if you can also please upload to https://www.dropbox.com/request/yPJAEaCcNAjvMw2Kqj2d when you are finished.
While I will definitely credit everyone in the video description, as well as the end credit roll, I'm also planning on having a graphic in the lower corner of the video, sort of like a station ID graphic, which will link to the channel of whoever's content is onscreen. So if a viewer sees a story or commercial that they just love, they can click the graphic to see more and hopefully subscribe. I'm also planning to have a brief intro video that explains how this works and at the end links to the full video. I will make the intro video available for everyone to upload to their own channel, or you can make your own explainer intro if you like. The idea is that if you upload the intro video and end link it to the full video, then you can share the intro video on your channel and get views for your own channel as well. I had considered doing a playlist, but I did some tests and waiting for the youtube loading pattern every 15 to 30 seconds would be super annoying.
