AI lipsync question

hi i am here for a question, i saw a girl on insta who did some ai video of her, i would like to do the same of her but after lot of research a can't find the good process/AI/workflow... if someone can help me please i don't put the instagram link of the vidéo because i am new here and i don't know if it's autorized, thanks at everyone who will answer

most of those viral ai vids are made using a combo of tools. if it's high quality, she's probably using Kling AI or Luma Dream Machine for the motion. for face consistency, people usually go with Stable Diffusion + Reactor extension. it's a bit of a learning curve but the results are top tier.

Few opensource model like wan2.2 s2v I got little good output by self hosting needs lots hassle
The better option, I think you can use proprietary saas like fal.ai, replicate,enhencor.ai etc, you can fine lots like them...
They are hosting almost all state of the art video gen model, and it is better if you enhance your prompt with llm like Gemini or Claude..
Beacause each video gen or image gen model has it's own prompt style and they have their own prompt guide..
For example, you are using veo3
Your prompt : A man is speaking <>

I've been using Veo3.1 lately. the image-to-video feature is good. if u have gemini pro, it's definitely worth a try.
