Can I use AI for making videos?

For close up shots I think you could get away with it but for full ai generated people I wouldnt use those in your niche as I feel it wouldnt help with client trust. I think closer shots of nails showing and beauty treatments are doable but with you having a client base I feel that real people and clients would be better proof of your work and real results than anything ai gen. You may find it more useful enhancing your videos though.
