Packing Input Frame Context in Next-Frame Prediction Models for Video Generation
- ilaksh 2y agoAmazing. If you have more RAM or something, can it go faster? Can you get even more speed on an H100 or H200?
- ZeroCool2u 2y agoWow, the examples are fairly impressive and the resources used to create them are practically trivial. Seems like inference can be run on previous generation consumer hardware. I'd like to see throughput stats for inference on a 5090 too at some point.
- IshKebab 2y agoFunny how it really wants people to dance. Even the guy sitting down for an interview just starts dancing sitting down.
- bravura 2y agoIt's a peculiar and fascinating observation you make. With static images, we always look for eyes. With video, we always look for dancing.
- Jaxkr 2y agoMassive open TikTok training set lots of video researchers use
- jonas21 2y agoPresumably they're dancing because it's in the prompt. You could change the prompt to have them do something else (but that would be less fun!)
- IshKebab 2y agoI'm no expert but are you sure there is a prompt?
- dragonwriter 2y agoYes, while the page here does not directly mention the prompts, the linked paper does, and the linked code repo shows that prompts are used as well.
- vunderba 2y ago100%. I don't think I've ever even come across an I2V model that didn't require at least a positive prompt. Some people get around it by integrating a vision LLM into their ComfyUI workflows however.
- IshKebab 2y agoAh yeah you're right - they seem to just really like giving dancing prompts. I guess they work well due to the training set.
- Jaxkr 2y agoThis guy is a genius; for those who don’t know he also brought us ControlNet. This is the first decent video generation model that runs on consumer hardware. Big deal and I expect ControlNet pose support soon too.
- msp26 2y agoI haven't bothered with video gen because I'm too impatient but isn't Wan pretty good too on regular hardware?
- dewarrn1 2y agoLTX-Video isn't quite the same quality as Wan, but the new distilled 0.9.6 version is pretty good and screamingly fast. https://github.com/Lightricks/LTX-Video https://github.com/Lightricks/LTX-Video
- vunderba 2y agoWan 2.1 is solid but you start to get pretty bad continuity / drift issues when genning more than 81 frames (approx 5 seconds of video) whereas FramePack lets you generate 1+ minute.
- dragonwriter 2y agoWan 2.1 (and Hunyuan and LTXV, in descending ordee of overall video quality but each has unique strengths) work well—but slow, except LTXV—for short (single digit seconds at their usual frame rates — 16 for WAN, 24 for LXTV, I forget for Hunyuan) videos on consumer hardware. But this blows them entirely out of the water on the length it can handle, so if it does so with coherence and quality across general prompts (especially if it is competitive with WAN and Hunyuan on trainability for concepts it may not handle normally) it is potentially a radical game changer.
- dragonwriter 2y agoFor completeness, I should note I'm talking about the 14B i2v and t2v WAN 2.1 models; there are others in the family, notably a set of 1.3B models that are presumably much faster, but I haven't worked with them as much
- fregocap 2y agolooks like the only motion it can do...is to dance
- enlyth 2y agoIt takes a text prompt along with the image input, dancing is presumably what they've used for the examples
- jsolson 2y agoIt can dance if it wants to... It can leave LLMs behind... 'Cause LLMs don't dance, and if they don't dance, well, they're no friends of mine.
- rhdunn 2y agoThat's a certified bop! ;) You should get elybeatmaker to do a remix! Edit: I didn't realize that this was actually a reference to Men Without Hats - The Safety Dance. I was referencing a different parody/allusion to that song!
- MyOutfitIsVague 2y agoThe AI Safety dance?
- dragonwriter 2y agoThere is plenty of non-dance motion (only one or two where its non-dance foot motion, but feet aren't the only things that move.)
- WithinReason 2y agoCould you do this spatially as well? E.g. generate the image top-down instead of all at once
- levzzz 2y ago[dead]
- modeless 2y agoCould this be used for video interpolation instead of extrapolation?
- yorwba 2y agoTheir "inverted anti-drifting" basically amounts to first extrapolating a lot and then interpolating backwards.
