# MinimaxHailuo03ContextIRNode - ComfyUI Built-in Node Documentation

> This node uses MiniMax H3 Context IR to analyze your text description and any attached media, then produces a stronger, structured video prompt.

This node uses MiniMax H3 Context IR to analyze your text description and any attached media, then produces a stronger, structured video prompt. The returned prompt is designed to be connected to the prompt input of a MiniMax H3 video node; if you attach media there, attach the same media in the same order, because the enhanced prompt refers to media by position.

## Inputs

### Parameter constraints

* The `prompt`, `duration`, `ratio`, `reference_images`, `reference_videos`, and `reference_audios` inputs are part of the `model` option group.
* `first_frame` and `last_frame` cannot be combined with any reference media.
* `reference_audios` cannot be used unless at least one `reference_image` or `reference_video` is also connected.
* When no frames and no reference media are connected, `ratio` cannot be set to `"adaptive"`.
* Reference videos must be approximately 2-15 seconds each, with a total duration of no more than 15 seconds. Their frame rate must be between 23.9 and 60.5 FPS.
* Reference audios must be approximately 2-15 seconds each, with a total duration of no more than 15 seconds.
* `first_frame`, `last_frame`, and every reference image must be at least 256x256 pixels and have an aspect ratio between 0.4 and 2.5.
