Making AI vids is a pain in the ass. 100 times harder then generate pics. Y need realy strong PC and learning some stuff before. Than download prog (comfy AI for example), rightly setup it, find good workflows, chekpoints and loras etc...
For me, compleatly new in this shit it all took about 5-6 hours, before i could generate some good anims. BUT, worst part in this all its time consuming. For me and my 4070S generate 5 sec 720p vid is about 15-20 min. If y have better gpu - y il do faster obviosly.
Imho, if y not planing to making money from that (make games, joi, another tipe of shit) - it totally not worsed to wasting time. Just play a little with that and forget. Dont torture y PC buddy
