Hey, I host videos occasionally for some players who don't use Youtube, but stream and save to Twitch. But it's becoming a bit combersome to donwload, reupload, give to them, etc.

Is it acceptable to make a "redirect video" that is a filler, and has links to the games on Twitch in the comments section below?

What do you mean by filler?

If you mean simply link the twitch version instead then yea, you can do that.

Highlight it on twitch and just provide the highlight link in the submission.

Haha, wow, I guess you can just use Twitch Highlights. I swore I tried that and it didn't work, I just assumed it was Youtube only because that's all I've seen. I guess that solves itself!
