<h2 id="lorageek-complex-prompt-generator-the-beatbox">🥁 LoraGeek Complex Prompt Generator - the Beatbox</h2>Write your scene as a list of beats. One button builds the whole long, layered prompt and writes it straight into your video node, where you can read it and edit it.Some of the best talking-video clips come from long, layered prompts: a scene line, numbered shots, a camera block, every action in order, every spoken line, the sound design. Writing that by hand each time is slow, and one mistake makes the model mumble.<h2 id="the-beatbox">The Beatbox</h2>Each shot has one Beatbox. Write what happens in order, one beat per line. Actions and speech go in the same box, so the order is exactly what you wrote.<ul><li>Speech is in "quotes", or written Mary says: ..., or Mary: ...</li><li>Everything else is an action</li></ul><pre><code>She sips her coffee.
She: "Ow, that's hot."
He: "Maybe blow on it."
She blows on it.
He: "Yeah, that's better."
</code></pre>The node writes it as First / Then / Then steps, and after every spoken line it adds "then she is quiet, lips closed" so the model knows the talking is over.<h2 id="the-beatbox-camera-a-field-of-buttons">The Beatbox Camera - a field of buttons</h2>A second panel ships with it and sits beside the generator. Click camera choices and the generator writes them into the prompt.<ul><li>Look (cinematic, phone footage, documentary...), shot size, angle, placement</li><li>Camera moves (push in, pull out, pan, tilt, truck, arc, tracking, POV...) with size and speed</li><li>Focal length, aperture, depth of field, lighting</li><li>Over-the-shoulder on each speaker - every spoken line cuts behind the listener's shoulder</li><li>Click the i next to a section for a plain-English explanation of each button</li><li>Buttons marked with a star are in the official H3 prompt guide. The rest are plain descriptive English.</li></ul><h2 id="the-right-format">The right format</h2>The prompt is written the way MiniMax H3's own guide describes: one block, <code>[Shot N]</code> markers, cut times like "At 00:03.500, the camera cuts to...", and speech in <code>&lt;d&gt;</code> tags with speaker IDs. Without the timestamps, later shots do not cut.<h2 id="you-can-see-the-prompt">You can SEE the prompt</h2>Press GENERATE PROMPT and the full prompt appears in your video node's own prompt box. Nothing is hidden and nothing is locked. Change one word ("left" to "right") and run.<h2 id="the-clip-length-is-set-for-you">The clip length is set for you</h2>Talking-video models fill silence with mumbling. So the node counts the spoken words and the actions in your beats and sets the duration box on the video node to fit.<ul><li>AUTO - fits the beats. MANUAL - you pick the seconds</li><li>Rough guide: 3.5 spoken words per second, half a second per action</li><li>A status line tells you what it set</li></ul><h2 id="what-you-fill-in">What you fill in</h2><ul><li>Scene setup - where and when, written into every shot</li><li>Subjects - who is in it, one per line</li><li>Camera style - shows what the camera panel added (or type your own words)</li><li>4 Beatboxes - one per shot</li><li>Filler line - a tiny line for shots with no speech</li><li>Soundscape - real, specific sounds (feet on tile, a fan humming)</li></ul><h2 id="why-the-filler-line-and-the-soundscape-matter">Why the filler line and the soundscape matter</h2>A shot where nobody speaks is where H3 tends to babble. Give every shot something to say, even "Mm-hm", and give it real room sounds. Both help a lot.<h2 id="install">Install</h2><ul><li>Download the zip and unzip it</li><li>Put the ComfyUI-ComplexPromptGenerator folder into ComfyUI/custom_nodes/</li><li>Restart ComfyUI, then hard-refresh the browser page (Ctrl+Shift+R)</li><li>No extra Python packages needed</li><li>The full step-by-step guide (<a target="_blank" rel="ugc" href="http://GUIDE.md">GUIDE.md</a>) is in the zip</li></ul><h2 id="how-to-use-it">How to use it</h2><ul><li>Double-click the canvas, type Complex Prompt Generator</li><li>The camera panel appears beside it on its own. Nothing to wire</li><li>Fill in the boxes, write your beats, click any camera buttons</li><li>Press GENERATE PROMPT</li><li>Check the prompt box on your video node, edit if you like, and run</li></ul>It looks for the video node's prompt box and duration box. It works with the Image to Video (MiniMax H3) template. On another workflow it writes to the first prompt box it finds.<h2 id="good-to-know">Good to know</h2><ul><li>It is a template, not an AI. It costs no VRAM and adds no extra model.</li><li>The detail in your beats is what makes the prompt good.</li><li>Written for MiniMax H3, but the prompt is plain text.</li></ul>MIT licence.
