Drive the LTX Director (Timeline) node. Its Add Image/Text/Audio buttons are DOM-only and cannot be clicked by an agent; edit the hidden timeline_data JSON widget instead. Load when a workflow contains LTXDirector / LTXDirectorGuide / PromptRelayEncodeTimeline, or when asked to add, move, retime, or remove timeline segments (image / text / audio / motion).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# LTX Director (Timeline)
`LTXDirector` (pack: **WhatDreamsCost-ComfyUI**, category `WhatDreamsCost`) is a
video *timeline editor* node. Its on-canvas UI has **Add Image**, **Add Text**
and **Add Audio** buttons.
## You cannot click those buttons. Don't try.
They are not node inputs. The pack builds them as raw DOM elements with JS
handlers:
```js
addTextBtn.addEventListener("click", () => this.addTextSegmentFreeSpace());
```
Panel/MCP tools drive the LiteGraph **node model** (widgets + inputs). They
cannot invoke arbitrary DOM handlers, so "click Add Text" is impossible. This
is a hard limitation, not flakiness. Say so plainly rather than retrying.
## The real control surface: `timeline_data`
Everything those buttons do is serialized into ONE string widget, `timeline_data`.
The pack's own code treats it as *"the absolute source of truth"*. Set it and the
editor renders it.
It is listed in the pack's `HIDDEN_WIDGET_NAMES`, so it does **not** appear in the
node's visible widget list, but it is an ordinary input and is settable:
```
create_workflow(action="modify", workflow=<the graph>, operations=[
{ op: "set_input", node_id: "42",

How to install
mdr add artokun/comfyui-mcp/ltx-director@sha256:19acfd6823a884bfThe line at the top of this page pins the label git:20260825.973d578, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
