Key features

H3 Video Extend turns a video you already have into video inside Enhance AI. It produces clips from 3 to 15 seconds at a resolution you choose, 480p by default. H3 Video Extend is built by MiniMax. On Enhance AI it runs on the same account as every other model, with no separate subscription.

Clip length

H3 Video Extend renders clips from 3 to 15 seconds, and you pick the length before you render. Longer clips cost more because video is billed by length, so rough out an idea short and only render the full length once the shot works.

Resolution

Choose 480p or 768p before you render. A lower resolution costs less, so test a prompt low and rerender the keeper at the top setting. The studio shows the price for the setting you picked before anything is charged.

Input modes

Upload a video you already have and H3 Video Extend continues it from the last frame, so the new segment matches the light, the framing and the motion of the original. Describe what should happen next and the model carries the shot forward without a visible join.

Audio

H3 Video Extend can generate sound with the picture, so the clip arrives with audio that matches what is on screen rather than silence you have to fill later. You can still mute it and lay your own voice or music track over the top in any editor.

What people make with H3 Video Extend

Fixing an ending

When a generated clip is right for most of its length and falls apart at the end, trim it before the problem and extend from there. H3 Video Extend continues from the last good frame, which is far cheaper than rerolling the whole shot and hoping for a better result the second time.

Building a sequence

Chain extensions to build a sequence a single render could not hold: establish the scene, extend into the action, extend again for the reaction. Each pass starts from the last frame, so continuity is built in. Plan the beats up front and give every extension one clear instruction.

Filling a cut

Editors use H3 Video Extend to make a clip long enough for a cut that needs a beat more time: a hold on a face, a slower pull back, a moment before the transition. A short extension is often the difference between a cut that feels rushed and one that breathes.
