You say you want to contribute to the forum, which is cool. Lots of people lurk forever, and the most they offer up is their two cents now and again. Like me, for example. So to be inspired to create something novel is highly admirable. You've got a lot of potential here on this forum. I think I'm among many people here who figure your best work to date has been the absolutely killer Paint Wars, and that your obvious talent is wasted taking on the pretty... uh... "mundane" task of doing DVD -> AVI -> DVD conversions. So I would respectfully submit you've already begun a highly-worthy contribution, and I would urge you to continue your excellent and unique Paint Wars series.
I was totally shocked by how quickly you were pumping out pictures, but it seems as though it came at a price: you've decided from your brief spurt of work that it's going to be too difficult to finish the whole film. I say, "Well, duh!" If you work at that pace, it's got to be draining. I couldn't believe you got as far as you did in such a short time. Crazy!
But how about setting a much more modest target, over a longer period of time? Aim for 10 pictures a week (say...), and don't let it take up more time than that. Or at least average 10 pictures a week -- if you feel inspired to crank out 20 one week and none the next, so be it. If you average 10 pictures for each 2 minutes of film time, then ANH will take about 500 more pictures. 10 a week, and you'd be finished up by next Christmas, easy.
You've got a lot of support here on the forum. It'd be cool if you could channel that goodwill and positive vibe into a nice, stable, completable project!
