It is not working. Just don't believe them what they say.
I just wanted to clone ad, I click button, it took all my tokens, plus there was a output like a very bad quality AI video and far far away from the video that I cloned from. I talked with the support, they offer me to add credits, and they didn't believe me it took all my tokens for a 1 video. I sent them a screenshot to prove it. but I didn't trust them or their service to get a good quality video. I asked for a refund, and they said they can't. well let's see what my bank says.
