## README

# ComfyUI-LTXTricks

A set of nodes that provide additional controls for the LTX Video model

## Installation

There are no additional packages required. The [ComfyUI examples page](https://comfyanonymous.github.io/ComfyUI_examples/ltxv/) can get you started if you haven't already used LTX.

## Examples

Example workflows can be found in the `example_workflows` directory.

## RF-Inversion
This is an implementation of [RF-Inversion](https://rf-inversion.github.io/) and an [example workflow can be found here](https://github.com/logtd/ComfyUI-LTXTricks/blob/main/example_workflows/example_ltx_inversion.json).

## RF-Edit
This is an implementation of [RF-Solver-Edit](https://github.com/wangjiangshan0725/RF-Solver-Edit) and an [example workflow can be found here](https://github.com/logtd/ComfyUI-LTXTricks/blob/main/example_workflows/example_ltx_rf_edit.json).

## FlowEdit
This is an implementation of [FlowEdit](https://github.com/fallenshock/FlowEdit) and an [example workflow can be found here](https://github.com/logtd/ComfyUI-LTXTricks/blob/main/example_workflows/example_ltx_flow_edit.json).




## Image and Video to Video (I+V2V)
This is a method to perform Video to Video while using a reference image.

Use [this example workflow](https://github.com/logtd/ComfyUI-LTXTricks/blob/main/example_workflows/example_ltx_iv2v.json) for getting started. Results may vary.

## Enhance
A portion of [Spatiotemporal Skip Guidance
for Enhanced Video Diffusion Sampling](https://junhahyung.github.io/STGuidance/) (STG) has been implemented. Planning to add the "Restart" feature when time allows.

Use [this example workflow](https://github.com/logtd/ComfyUI-LTXTricks/blob/main/example_workflows/example_ltxv_stg.json) to see how it works.

Left is without STG, and right is with STG.

## Interpolation and Frame Setting
A set of nodes have been included to set specific latents to frames instead of just the first latent. An [example workflow can be found here](https://github.com/logtd/ComfyUI-LTXTricks/blob/main/example_workflows/example_ltx_interpolation.json).
