LTX-Video demo code?

Hi, where can we find the code used for the ltx video tensorrt rtx as shown in the youtube video?

Hi @yuvraj108c - thanks for the comment!

The LTX-Video integration demonstrated was an initial experimental prototype. At this time, the repository only includes the Flux.1 [dev] demo as a reference implementation showcasing TensorRT-RTX features including:

• Runtime cache
• Dynamic shape specialization
• Various precision options (bf16, fp8, fp4)
• Memory management for larger models

The pipeline patterns and optimization strategies shown in the Flux demo can be applied to other diffusion-based models as well. Additional demos may be added in the future.

Thanks for the reply!

Video diffusion models are more complex unlike image models. I've tried optimising the same LTX video model using original tensorrt in the past, but it wasn't working as expected. There aren't currently any other tensorrt-based implementation of video diffusion models I can find. Thus, this notebook, even if experimental, will be very useful to the community.

Hopefully, it can be published soon or shared unofficially. Thanks a lot!
