What this node does
Annotate overlays a chosen graphic onto the clip using ffmpeg draw/border/scroll filters. Pick a mode and its parameters; on ▶ Run it burns the result into a new video. It is a single-filter pass, not a drawing surface — you set numeric position/size rather than click on the frame. Video in/out isCOMFYTV_VIDEO. Bridge to native ComfyUI nodes via ComfyTV/Bridge — see https://github.com/jtydhr88/ComfyTV/blob/main/docs/bridges.md.
When to use it
- Highlight a region with a colored box for a tutorial or review
- Overlay a reference grid (rule-of-thirds, safe areas)
- Fill or mirror black borders after a crop, or scroll the frame content

Outputs
Tips
box/gridshare color, thickness and opacity;fillbordersuses border_mode + border_px;scrolluses scroll_h/scroll_v — the card only shows the controls for the active mode.- The overlay is burned in permanently; keep an un-annotated version if you may need the clean plate later.
fillbordersis the natural follow-up to a crop that left black bars.
