I hate giving negative reviews but found this product to be a tedious waste of time. First of all (after paying for it) I kept getting messages about Runwayml. I look in the support system, but can't find anything about it. I waste ages trying to figure it out, and eventually (thanks to some of the Appsumo reviews) I discover that there is another service called Runwayml and it seems to get Vadoo working. You need to get this API. It's weird that there's no mention of it in the welcome email. So I sign up for Runwayml which, as with all these things, is tedious as you enter lots of details, then wait for emails with codes in then enter the code, then more information, and blah blah. Then it turns out that this isn't actually the one you need to sign up to. There's a developer version, but weirdly that doesn't seem to accept the same login details, so you have to go through the whole signing up process another time. Phew! I am nearly there. I grab an API code and rush back to Vadoo and find where to enter it (remember, no instructions are given). Awesome. I am rockin and rollin. Alas not. I go in to generate an AI video and get told that even though I clearly have 1000 credits (it is showing that on the screen) I do not apparently have enough credits to generate a 5 second video. What a waste of time. I was puzzled as to why there are so many positive reviews, but now realise that you get given 500 extra credits if you post a nice review, which seems unethical. Sorry to be a downer on this, as it looks as though it has potential, but might I suggest much clearer instructions and a credit system that doesn't tell you that you have no credits when it is showing you have 1000? As for the credits you get after buying on Appsumo I am assuming that they must be for something other than AI video, but by now I have pretty much given up. I did message there support yesterday, but have had a reply so it looks like it with be a Tier 2 refund.
