H3 Video Edit: AI video editing
Rewrite the lighting, style, weather or elements of a video from a prompt, with native audio. 480p or 768p.
Free credits on signup, no card required. Plans from $19 one time.

Key features
H3 Video Edit produces clips from 3 to 15 seconds at a resolution you choose, 480p by default. On top of that it renders 16:9, 9:16, 1:1, 4:3, 3:4, 21:9 and 9:21. H3 Video Edit 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 Edit 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 the clip you want to change and describe the change in words. H3 Video Edit keeps the framing and the timing of the original and rewrites only what you asked for, so an edit is a rerender rather than a reshoot.
Aspect ratios
H3 Video Edit renders 16:9, 9:16, 1:1, 4:3, 3:4, 21:9 and 9:21. Pick the ratio for the platform before you render rather than cropping afterwards: 9:16 for Reels and Shorts, 16:9 for YouTube, 1:1 for feeds and 21:9 for cinema. The whole frame is generated for that shape.
Audio
H3 Video Edit 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 Edit
Swapping a background
Keep the subject and replace where it stands: a studio wall becomes a street, a kitchen becomes a beach. H3 Video Edit works from the clip and a plain description of the new setting, so a product demo or a talking head can travel without anyone leaving the room.
Style passes
Turn live footage into an animation, a painting or a film look with one instruction. H3 Video Edit applies the style across the whole clip so frames stay consistent instead of flickering, which is what makes it usable for a music video, an intro or a social series with a fixed look.
Removing and adding elements
Ask H3 Video Edit to take a logo off a wall, add rain, change a shirt colour or put a car in an empty street. Describe the change and nothing else; the model keeps everything you did not mention. Small, specific edits render more reliably than a long list of changes.
