Quote from YunI'll explain how to get the sponsorship since I got the opportunity to get my music video sponsored.
First off, before you make a TON of progress on your animation that you want to sponsor, you would give a short or a decent snippet to an admin of the website. [ EG stone, CRAZY JAY, TheSaw, etc. ] You give them the background story on what it will be about. If it sounds interesting and may look like it will have that sponsor quality that they're expecting, they'll give you the green light and go ahead onto continuing the animation. To be sure on keeping that green light, you would give them progress on how your animation looks. As you do that, you will know that you're doing great. There will be some guidelines they will give you to follow. Once everything is done and it is at least over 2 minutes long, they will speculate how much you will get through PayPal. They'll give you the money, you give them the SWF, and they will release it on a Friday.
Sounds awesome. Also, what music video did you made?
