Media Describe - Overrides

The whole reason Media Describe splits its output into five paragraphs - subject, clothing, movement, scene, visual style - is so you can change one of them without throwing the rest away. Media Describe - Overrides is the node that makes that concrete: it collects your edits into a single overrides object that MediaDescribe applies before assembling the final prompt.

Every input is optional, and each one maps to a paragraph in the generated description. override_subject replaces the SUBJECT paragraph. override_visual_style replaces the visual-style paragraph (the tooltip notes it combines cinematic/aesthetic and stylization/tone). override_clothing swaps the clothing paragraph. override_scene and override_movement do the same for the scene and movement paragraphs - the tooltips flag that those two are video-only fields, so on a pure image description they have nothing to bite on. On top of the paragraph swaps, prompt_prefix prepends arbitrary text before the whole generated description - handy for injecting a fixed style tag or a character name you always want leading the prompt.

The mechanism is as simple as it looks: the node packages your text into an OVERRIDES object (one output) that you wire into MediaDescribe's overrides input. MediaDescribe checks each field: if you provided text, that paragraph comes from you instead of the model; if you left it empty, the model's output stands. Empty fields are silent pass-throughs, which is what makes the node comfortable to leave in the graph permanently - a template you fill in only when you want to intervene.

That's the workflow this pack is really selling: run the caption, read the breakdown in Control Panel Prompt Breakdown, spot that the "clothing" paragraph hallucinated a color, type the correction into this node, re-run. You get the same subject, scene, and style as before with a fix applied to exactly the one thing that was wrong. No full regeneration, no prompt re-engineering of the whole description.

Gotchas

• It's a packaging node. It does nothing on its own - no outputs that show anything, no validation of your text. The payoff is entirely in how MediaDescribe consumes the object.
• Scene and movement are video-only. On an image describe they're ignored, so don't be confused when your scene override doesn't change an image result.
• Overrides replace wholesale. There's no merge logic - whatever you type is the whole paragraph. Keep your replacement self-contained or you'll lose surrounding detail the model got right.
• Since all fields are optional, it's safe to wire in permanently and fill in as needed.

If you're iterating on captioned media, this is the difference between nudging a result and rebuilding it. It's the pack's answer to "the model got it 90% right."
