I typically try not to archive whole streams. I just feel like I would be abusing Twitch's system by doing that (Im sure others do this anyway). I dunno. If I find a worthy highlight I will save that.
Highlight it in multiple segments, name then x.1, x.2, x.3, like I do. You can then cut out load time or idle time or whatever.
Alternatively, dump your twitch video onto your computer via flash-download which you can do from browser addons. Edit a bit of it and condense it to just active gameplay (cut out PT visits), and upload it to a youtube.
While you are at it, record your facecam and make loud commentary in a colorful dialect or variety of voices, and be some million subscriber hit. I am just asking because that would be REALLY healthy for the game's popularity lol. But seriously, the first suggestion as well as the second are serious.
Not bad suggestions. Thank you. As I said if I find something highlight worthy, I will work my editing magic!
