# LTX Video 2.3 — V2V Style Transfer (ReStyle IC-LoRA)

**Model:** LTX Video 2.3 — 22B Dev (FP8) + ReStyle IC-LoRA
**Type:** Video-to-Video

Video-to-Video style transfer using a custom-trained IC-LoRA on top of LTX Video 2.3 — 22B. Takes a content video and a style reference image, and re-renders the video in the reference style. The IC-LoRA guide is composited via `LTXAddVideoICLoRAGuideAdvanced`, with the distilled speed-up LoRA applied for fast 8-step sampling.

## Notes

- **Inputs:** a content video (`VHS_LoadVideo`) and a single style reference image (`LoadImage`). The reference image and the first frame of the content video are resized to the desired resolution with `nvidia_rtx_vsr` and concatenated into the IC-LoRA guide via `LTXAddVideoICLoRAGuideAdvanced`.
- **Sampling:** `euler` sampler, `linear_quadratic` scheduler, 8 steps, CFG 1.

## Training

This IC-LoRA was trained on [RunPod cloud GPUs](https://runpod.io?ref=vpp0cion).

## Support

Producing and sharing this kind of open-source work requires renting cloud GPUs, which gets expensive quickly. If you find it useful and would like me to keep contributing, your support is very much appreciated:
