Good question, I would also like to know the program.
So...what AI would one use to make videos like this?
I remember t4bbo mentioning ai for the first time maaaany months ago, so I'd assume he has been looking into for a quite some time now. I'd guess he probably has a local thing going on, could be a mix of different workflows - hard to tell exactly what he is generating these vids. so if you are expecting an AI chatbot, like gpt, grok, etc. that you can just type 'draw a girl in a car sucking the driver's cock' and animate them through the popular but limited options, e.g runway, there is no website combination out there you can generate such long and high quality image 2 video content as t4bbo's, at least that I know.
However, if you are interested in allocating your time, hardwork and money (you'll need a powerful setup), you can do wonders with gen AI. I'd suggest you look into comfyui, check out civitai; the models, loras, copy others workflows, experiment a bit and you'll get the grasp of it in no time. good luck!
