LTX Director Motion Brush

LTX Director Motion Brush is a ComfyUI workflow/node pack for turning storyboard images and per-image Motion Brush tracks into sparse IC-LoRA motion-control guide video and LTX 2.3 shots.

Draw motion tracks directly on storyboard images, convert them into sparse IC-LoRA motion-control guide video, and build LTX 2.3 shots with Director-style timing, retake workflows, matte clips, per-image guide strength, and motion-carry transitions.

The workflow file is LTX_Director_Motion_Brush_V2.json and includes 58 nodes, including motion-brush, guide-video, retake-preview, video-creation, and video-saving nodes.

Its inputs are storyboard images and per-image Motion Brush tracks; its outputs are sparse IC-LoRA motion-control guide video and LTX 2.3 shots.

Before using it, have ComfyUI-LTXVideo, comfyui-kjnodes, ComfyUI-Impact-Pack, an LTX 2.3 model setup, and LTX 2.3 IC-LoRA motion-track-control plus IC-LoRA-ingredients ready.

GGUF and Full model workflow variants are available for low VRAM.
