I'm not quite clear on that obsolete movie deleting idea, if it's what I think it is it seems a little unnecessary... usually the filenames have v2, then the new one is called v3, etc, but I guess that's not very reliable as frenom's megamanx video is labeled v3 and wodball's newest is v2. The best way right now to do it would probably be to go thorugh the movie list on the site and compare the file size, author name, and length to the different versions of the appropriate game. But anyway.
Bisqwit and phil right now are comfortable with being the ones who encode the videos, as is my understanding. You happen to come at a time when a couple people are also offering to seed constantly(see
http://tasvideos.org/forum/viewtopic.php?t=342&start=30 ), but nothing has happened as of yet so your help would be greatly appreciated.
Personally I think the best way one could help the community is by making good videos, heh. But we certainly do need seeds. There are many people just like you who have joined the community(usually through the boards first, then started participating in the IRC channel) who didn't think they'd have the skills to make any videos, then as they got more involved in the community they ended up trying anyway. Everyone welcomes you to post more and join in the channel, of course.
