I hate those pages. They typically have a popup that brings you to a normal written sales page with a buy button if you try to close the page, though.

Its just unbelievable. Im sure i can make 25 times better sales text in three short sections and sell your product with 220% efficiency comparing to your Über-hyped nonsense. Ah yes. I wont have a direct link and have to lead traffic still to your half hour animations.

They must work if people keep doing them right?

Well there seem to be a fragment of truth in your words.

But i would like to hear about some comparisons between video- and text LP's.

It's interesting for me because youtube generation is indeed lazy to read longer sales content and prefer to watch cartoons instead. But from psychologic perspective of those same lazy readers they wont watch 25 minutes sales cartoon either. And if there is no "skip-the-crap-and-buy-the-product" button - i'm curious how much it converts.

If here is some marketer who is hands-on with both parallels - i would be curious to hear about practical difference.

This is one of those things that personifies the wierd yet wonderful world of affiliate marketing!

You tend to see these videos in Niches where people are used to being sold to e.g make money online/dating/gambling etc.

I would imagine its a way of combating "banner blindness" whilst also presenting yourself as a professional.

I have tried the video opt in page before - granted it was only 5 mins long and I set the capture form to show half way through the video - yet the conversions were no different to a normal text LP.
