How to write an H3 Max text to video prompt

  1. Lead with who/what is on screen and where they are.
  2. Add one dominant camera move (dolly, handheld, locked-off).
  3. Specify lighting and lens language you can actually see.
  4. Describe sound if your endpoint returns audio in the same pass.
  5. Keep duration short for drafts (5–8s @ 480p/768p), then lengthen winners.

H3 Max is tuned for fast iteration at 480p/768p. For heavier 2K / reference-heavy workflows, people often switch to full MiniMax H3 — this page stays focused on text to video prompts for H3 Max.

FAQ

What is an H3 Max text to video prompt?

It is a single text brief that tells MiniMax H3 Max what to generate: subject, action, camera, look, and often sound. This generator formats those pieces into one paste-ready block.

Where do I run the prompt?

Common options include the fal H3 Max playground/API and MiniMax / Hailuo surfaces. This site does not generate video itself — it builds the prompt you paste there.

What duration and resolution should I use first?

Start with 5 seconds at 768P (or 480P for faster drafts). Stretch to 10–15 seconds only after the framing works.

Should I include sound in the prompt?

If your endpoint returns native audio with the clip, yes — describe diegetic sound clearly. If you are on a picture-only path, keep the visual brief tight and skip soundtrack fluff.
