ntsc-td

TouchDesigner Custom TOP that runs ntsc-rs on the CPU. Same signal chain as the standalone app: composite encode, VHS, head switching, ringing, and the rest.

Requires TouchDesigner 2025.31760 (TOP API 12), Windows x64.

Install
Download Ntsc.dll and put it in a Plugins folder next to your .toe, or in Documents/Derivative/Plugins.
Fully quit TouchDesigner and open the project again (plugins are scanned only at startup).
Tab → TOP → NTSC (type Ntscrs).
If TouchDesigner asks whether to trust the plugin, allow it.

Notes
Frames are 8-bit BGRA. The node does not resample — put a Resolution TOP at 720×480 (or 480×720) in front of it.
Parameters match the ntsc-rs app, including JSON presets from that app.
This is a heavy CPU process, not a GPU shader. At 720×480 the cook can take a full frame or more, so project FPS may drop below 60. Larger resolutions make it worse. Watch Info CHOP process_ms / cook_ms.
Default path keeps the node one frame behind so the GPU download does not stall. Turn on Low Latency (Stall) only if you need the current frame.
