Ah, okay. Thought it is something with cut, insert and merge or maybe smart encoding where only the added or modified content is encoded and merged together with the rest.
I did video editing myself years ago, did a concert movie in 720p/1080p of Nine Inch Nails material that was pushed from Trent to the net with multiple camera angles. Was editing it over a few month with Vegas, used Avisynth as frame server and encoded with MeGUI. Maybe the result is something for the Spleen too, maybe I share it there some day. The torrent is inactive on DIME now.
I remember that I was able to smart render some parts.
Sorry for the off topic.
you did Lights In The Sky (“the Gift”)? if so, you are AWESOME
