Nvidia’s new tech reduces VRAM usage by up to 96% in beta demo — RTX Neural Texture Compression looks impressive
Enter FramePack: a new architecture that compresses input frames, based on their importance, into a fixed-size context length, drastically reducing GPU memory overhead. All frames must be compressed to converge at a desired upper bound for the context length. The authors describe the computational costs as similar to image diffusion.
Coupled with techniques to mitigate “drifting”, where the quality degrades with the video’s length, FramePack offers longer video generation without significant compromise to fidelity. As it stands, FramePack requires an RTX 30/40/50 series GPU with support for the FP16 and BF16 data formats. Support on Turing and older architectures has not been verified, with no mention of AMD/Intel hardware. Linux is also among the supported Operating Systems.
Aside from the RTX 3050 4GB, most modern (RTX) GPUs meet or exceed the 6GB criteria. In terms of speed, an RTX 4090 can dish out as many as 0.6 frames/second (optimized with teacache), so your mileage will vary depending on your graphics card. Either way, each frame will be displayed after it is generated, providing immediate visual feedback.
The employed model likely has a 30 FPS cap, which might be limiting for many users. That said, instead of relying on costly third-party services, FramePack is paving the way to make AI video generation more accessible for the average consumer. Even if you’re not a content creator, this is an entertaining tool for making GIFs, memes, and whatnot. I know I’ll be giving it a go in my free time.
