Ok, so what we seem to have so far:
Each clip/segment approximately 5-10 seconds long, cut down from whatever is submitted right?
Showreel approximately two minutes in length.
720p resolution.
Single audio track for the main one, with the possibility of another with the original clips audio.
Final showreel will get linked to on the main site, thus becoming "official".
Anything can be submitted, and after the chosen date, the users vote on what will be used, based on either visual quality or technical merit.
The showreel should demonstrate both visual quality, and technical abilities of construct in various area's available, (so nobody is left feeling they're not good enough to submit anything for it).
Submissions can be either executable demo's (with instructions) or properly recorded video clips (at the correct resolution).
Anyone should be allowed to enter, if they have only 1 post or 1000.
The only real "rule" is that their submission has to have been done in construct, and be their own work, obviously.
Any other suggestions or ideas?
