Why AI video prompts are different
Writing prompts for AI video generation is closer to writing a shot list than describing an image. The models respond to structure: which shot is which, what the camera does, how fast it moves, and what sounds accompany the scene.
Vague prompts produce flat, generic 6-second clips. Structured prompts with camera direction, explicit action sequences and audio cues produce cinematic results with controlled motion and native sound.
Promptnomicon is optimized for MiniMax H3 (the model behind Hailuo AI) — currently one of the strongest text-to-video models available, with 2K output and native stereo audio.
Everything you can generate
Text to Video
Describe your idea in plain language — actions, setting, mood and audio. Promptnomicon generates a structured prompt with shot labels, camera moves and an AUDIO block.
Image to Video
Upload a starting image and describe what happens next. The prompt focuses on motion and action — appearance is already defined by your image.
Start + End Frame
Upload two images and get a transition prompt. The model generates the motion between your starting and ending frames with controlled pacing.

Frequently Asked Questions
Which video models are supported?
Promptnomicon currently generates prompts optimized for MiniMax H3, the model behind Hailuo AI. The prompt structure also works on fal.ai, WaveSpeed AI and Atlas Cloud H3 endpoints. Wan 2.1 support is coming soon.
Can I generate NSFW video prompts?
Yes. With Forbidden Mode and Pro Spells, Promptnomicon generates explicit adult video prompts optimized for platforms that support this content, such as Hailuo AI with adult content enabled.
Do video prompts cost more spells?
Yes — 2 spells per generation instead of 1, due to the two-stage pipeline used for image-to-video (vision analysis + prompt generation).
Is there a difference between text-to-video and image-to-video prompts?
Yes. Text-to-video prompts include full scene and subject description. Image-to-video prompts focus on motion only — appearance is already defined by the uploaded image, so redescribing it wastes the model's context.
