Actually there isn't much yet video portals to get paid. For screensavers and ringtones the payout rates has been low, so you will earn only 30% of revenues. Basically there is VAT, then mobile operators fee which will give billing aggregators 50/50. Afterwards you need to have billing and distribution infrastructure in place, so Bango is leading globally with lowest cost (around $1000 per month for global). Mobile video is 3GP, so you need to license good technology for distribution.
I would love to implement this with my
Indie Media and Artist site, but first I need enough artists to sign up that this business model will be viable and I need to get the revenue split at least 50/50 with the artist. So either I should license billing infrastructure directly from operators, or find other ways. Bango is offering up to 75% payour rate using Pay for It scheme in UK, so it's a good start.
