I've been working on something adjacent to this concept with Ragdoll (https://github.com/bennyschmidt/ragdoll-studio), but focused not just on creating characters but producing creative deliverables using them.

#82i wonder how long would it take for this technology to advance to a point where nice people from /r/freefolk would be able to remake seasons 7 and 8 of Game of Thrones to have a nice proper ending? 5 years, 10?

#83Is there any limitation on the video length?
Our transformer model was trained to generate videos that are up to 8s in length. However, we can make videos that are longer by using it an an autoregressive manner, and taking the last N frames of output i to seed output (i+1). It is important to use more than just 1 frame. Otherwise ,the direction of movement can suddenly change, which looks very uncanny. Admittedly, the autoregressive approach tends to accumulate…

#85quite slow btw
Yeah, it's about 5x slower than realtime with the current configuration. The good news is that diffusion models and transformers are constantly benefitting from new acceleration techniques. This was a big reason we wanted to take a bet on those architectures. Edit: If we generate videos at a lower resolution and with a fewer number of diffusion steps compared to what's used in the public configuration, we are able to…

Video compression algorithms use key frames. So can’t you do the same thing? Essentially, generate five seconds. Then pull out the last frame. Use some other AI model to enhance it (upscale, consistency with the original character, etc.). Then use that as the input for the next five seconds?

#89Tried my hardest to push this into the uncanny valley. I did, but it was pretty hard. Seems robust. https://6ammc3n5zzf5ljnz.public.blob.vercel-storage.com/inf2...
