Get traffic to your website/blog. If you know how to make video, you can provide this service and get paid
Upload it to youtube and other tube sites, adding CPA offers inside videos... Like at the start or end of the video add "Get FREE Iphone - Visit www.yourpromosite.com" or If you have Unique Tutorial Videos, you can sell them as PLR at warriorforums or at DP! or If you have lot of videos , upload them at tube sites for cash. There are lot of new tubesite owners looking for videos. They'll pay for uploads! Sit calm and think. You'll get lot of new ideas!
I've been running a video site since 2002 - let me tell you, it is the worst business venture you will ever get into. You'll have to really love doing it, because it will not pay off well (you'll be lucky if it breaks even most of the time). Your only options are PPC sidebar ads. If you're going to go for it, host your own videos - having them all on Youtube is going to look very lame and come off as unprofessional. However, Youtube is the only video program that has in-video advertising, so it's like a catch-22. Of course, if you want to just do a Youtube only thing, where you're running your own channel and promoting it, you can try it and see how it works. It better be extremely unique and interesting and VERY creative, though.
I now using http://www.plugadplay.com/ to earn from the videos. The downside of this is the payment is always delay.
I agree with Markn26. My advice is to do a niche video site. That way you can try to rank a little better for your niche and your conversions (adsense, etc) will have a better chance. If you just do a funny videos website, you've got to compete in one of the hardest markets online. And guess what, not only will you not rank 1st page for Funny Videos ever...but try buying some google adwords for these keywords. It will cost you thousands a day and you will get nothing in return. Another idea is find some product to connect your videos to. In other words, if you have a Nascar videos website, you can sell Nascar gear. That way at least you have a chance. BR
