If you are using Google's Video adsense unit than I think this is the right time to go for some other option. Because google is now withdrawing video adsense unit from the last week of April.

As per their comments this one was not so impressive and effective.

I had tried to get those going at one point, but the sign-up process between adsense and youtube kept spinning me around in circles - was very annoying and i finally gave up

never heard of anyone saying they had great success with this in any case

Google will be interested on those products which will bring money to them. So if this product does not make them rich than they do not need it and hence withdrawing this.

But however I am sure in future they will come with some more great features.

I didn't like this one... the ads stood out too much to make them unwieldy on websites. If they were more like the contextual youtube ads they'd have been much better
