MiniMax H3 Max — video extension and video from references

What MiniMax H3 Max is

MiniMax H3 Max is the video model from MiniMax — the makers of Hailuo. In generiram it does two things: it extends a finished clip, carrying on its motion, characters and setting, and it creates video from references — up to 9 photos and 3 short clips, from which it keeps faces, clothes and the product.

Versions and capabilities in generiram

VariantModeWhat it is for
MiniMax H3 Max ExtendVideo → VideoAdds 1–15 sec of new footage after the end of a clip lasting 1.6 to 60 sec; returns the whole clip.
MiniMax H3 MaxReferences → VideoA video of 1 to 15 sec from up to 9 photos and up to 3 videos (each 2 to 15 sec).
  • Resolutions 480p / 768p / 1080p; the price is per second, and when extending you only pay for the new seconds.
  • Long and numerous references make the request more expensive — the exact price sits on the button before you generate.

What it is good for

  • A longer clip from one you already have, without the characters changing.
  • Continuing a scene: what happens after the last frame.
  • An ad with a product and a model from photos.

How to write the description

When extending, describe what happens AFTER the end of the clip — don't repeat the beginning. With references, name them in the text (@Image1, @Video1) and say who does what.

Aspect ratios: 1:1, 9:16, 16:9 Lengths: 1 sec, 2 sec, 3 sec, 4 sec, 5 sec, 6 sec, 7 sec, 8 sec, 9 sec, 10 sec, 11 sec, 12 sec, 13 sec, 14 sec, 15 sec Price: 161 credits

Strong at

  • Extends a finished clip by 1–15 new seconds without changing the characters or the setting
  • Carries on the motion, lighting and style from the clip's last frames
  • Takes a source clip of 1.6 to 60 seconds and up to 50 MB
  • Three resolutions: 480p, 768p and 1080p
  • You pay for the added seconds, not for the whole clip

Weak at

  • Doesn't touch the clip itself — it only adds a continuation after the last frame
  • The aspect ratio and the characters come from the clip; a scene with different people won't work
  • The highest resolution is 1080p — no 2K or 4K
  • A long, dynamic source clip makes the generation cost more, because the model processes it as a reference

Don't use it for

  • Don't use it to change an existing clip — that's what the editing models are for
  • Don't use it for a clip under 1.6 seconds — the model won't accept it
  • Don't use it to swap the character or the setting — it continues, it doesn't remake

Typical tasks

  • Extend a short clip into a longer scene
  • Add action after the ending: the character turns around, walks off or smiles
  • Continue the shot with a camera move
  • Round off an ad clip with 5–10 more seconds

  • The aspect ratio comes from the references and can't be chosen separately
  • Lots of reference videos, or long ones, make the generation cost more

Don't use it for
