Basically every other con that has a vidshow like VVC's is in no position to turn down premieres. Con*Strict is a teensy 30-50 person one in Las Vegas; a couple of us who attend make something. Con.txt is way bigger, but still only gets a couple of premieres. Escapade has way more attending vidders, so it sometimes only shows one vid if somebody submitted a whole bunch, but it will almost always show at least one vid by anyone who submits, attending or not. (Which sometimes means some bizarre vids make it into the show, but I'd rather reward people for caring enough to submit something than worry about the tender sensibilities of viewers forced to sit through a couple of vids they don't love...) VVC is totally the worst of the lot for getting people to pay attention to your vid if you aren't actually at the con and/or friends with people who go. (I have no complaints about that, but I think it's clearly the case.) Media West isn't that satisfying because nobody posts con reports online, but they now accept dvd submissions from non-attending vidders, so I sent them an hour of my work.

Con show deadlines help me too. There are definitely some other options at various times of year.
