Advertisements on videos

I got a quick but important question.

I'm uploading videos unto my website. But I do not own the rights to show advertisements on the videos on YouTube.

Is there any other website/service that can offer advertisements on the video?

If Yes, Which one is the best?

greetings and thanks for responding!

I think video ad splasher might be what you're looking for.

You must have to try Vdopia.
It is a good site for advertisements easily.
