This AI technology is still years away in coming.
How it works:-
eg:- Mdm Zoe Tay as Mulan dressed in Wei Dynasty General's apparel battling Rouran forces.
1. Mdm Zoe will have to go for 3d scan of her head, as input into AI files.
2. A 30sec battle scene from Mulan movie will be searched out by AI
3. Using Mdm Zoe's eyes, nose & mouth as calculated reference points, her head will replaced the actual actress in the 30sec clip, using AI algorithms, thru UNREAL Engine 3d software for the photo-realistic look - every angle, light, secondary light, environment, dust, every single movement of even the battle armor, etc, etc.
4. Using current AI tech, it will take hours if not days to process the 30sec clip, as a high powered computer is needed for 4k resolution.
5. For rendering the 30sec clip -post production, it take days, if not weeks as just 1 frame alone will take hours. 1 sec =60frames. 30sec = 1,800 frames. A movie is made up of frames. Huge data servers would be needed.
So, for a full 90min movie created by AI, it will take months if not years to produce. Right now, the same 'text prompt' can be made by 3d graphic artistes within hrs & post production within days. Thus AI is still far away from taking over Human's jobs.
AI video tech is only good for Advertisements & commercial shots right now, which usually lasts less than 30 secs.
Also, COPYRIGHTS MUST BE ADHERED TOO, & cannot be a free for all, otherwise all kinds of fake videos will start circulating, creating chaos & confusion.
