LTX Director adds timeline editing and prompt relay to ComfyUI
A new ComfyUI custom node brings NLE-style timeline editing, prompt relay, and audio sync to local video workflows without external agents or API tokens.
LTX Director is a timeline editor custom node for ComfyUI that handles image-to-video, text-to-video, frame interpolation, prompt relay, and custom audio in a single node graph. The tool lets users sequence multiple clips, adjust timing, and sync audio directly inside ComfyUI without routing through external services or cloud APIs.
The interface is dense—timeline scrubbing, multi-track layering, and per-clip prompt controls all live in the node UI—but ComfyUI users already manage complex graphs. LTX Director consolidates what used to require separate nodes, file exports, and video editing software into one local workflow.
What stands out
- 01Timeline editing inside ComfyUI. Drag clips, adjust durations, and preview sequences without leaving the node graph. No round-trip to Premiere or DaVinci.
- 02Prompt relay between clips. Feed the end-frame prompt of one clip into the start of the next for smoother transitions and narrative continuity.
- 03Native audio sync. Drop an audio file into the timeline and the node aligns frame generation to the waveform—useful for music videos or dialogue-driven scenes.
- 04No external dependencies. Runs entirely local. No agent calls, no API tokens, no cloud upload. If you can run LTX Video in ComfyUI, you can run this.
- 05Frame-level fine control. FLFF support enables motion and style shifts mid-clip, a feature that typically requires manual keyframing in post.
