If this is still open, I'd love to jump in. (My stats: 263 subs with 29k views, 700 likes, 15,000+ followers.)[DOUBLEPOST=1387143198,1387092871][/DOUBLEPOST]There are many ways to collab:
- meeting and film, log in the same place, produce full sketches, google hangout/interview. Bake cookies together?
- film each section in separate (say if you are in different countries) then send the footage to one person to edit.
- If a channel is a lot bigger than another, maybe the smaller channel has a skill set the larger channel needs like sound production of special effects. Donate those skills for a link back at the end of the video.
- Getting together for full productions, maybe a web series or full length film.
- Online game play videos with audio from different players.
Just some thoughts. I think if you do this long enough you will have knocked them all out. I've done them all with the exception of game play videos.
