AI Video Editor
Upload a clip, type the change, get a re-rendered video. Molyin's AI video editor rewrites footage you already have — restyle the whole shot or swap a single detail — while the original motion, framing, and timing stay intact.
Edit Your Video Now
The studio below opens in Video Edit mode. Upload a 3–15 second clip, describe the edit in plain language, and add up to five reference images to pin the exact look.
Output length and aspect ratio follow the source video (3–15s).
What Is an AI Video Editor?
An AI video editor changes finished footage with instructions instead of timelines. Where a traditional editor makes you cut, mask, keyframe, and grade by hand, a video-to-video model reads your clip and your instruction, then re-renders every frame to match — the edit is described, not performed.
Molyin's editor runs on HappyHorse Video Edit, Alibaba Cloud's video-to-video model. It handles two families of edits in one pass: global style transfer — turn live footage into watercolor animation, anime, or a cinematic film look — and local replacement — swap an outfit, replace an object, change a background element. Because the model re-renders the clip rather than pasting an overlay on top, edits hold up frame after frame: motion, camera moves, and timing carry over from your source untouched.
Editing and generating live in the same studio: when you need brand-new footage instead, the AI video generator creates shots from text, images, and references with the same credits. Editing bills by your source clip's length, the studio shows the exact estimate before you submit, and every paid plan on the pricing page includes commercial usage rights.
What You Can Edit
One instruction box, two families of edits — global restyles and local swaps — plus the controls to keep results on-brief.
Style Transfer
Turn live footage into watercolor, anime, oil paint, or a cinematic film look — the whole clip re-rendered in a new visual language.
Object Replacement
Swap a product, prop, or background element for another — describe the change in words or show it with a reference image.
Outfit & Character Changes
Change clothing, costumes, or a character's look mid-shot while the performance underneath stays exactly the same.
Motion Preserved
Camera moves, action, and timing carry over from the source clip — output length and aspect ratio follow your footage automatically.
Reference Image Control
Attach up to 5 reference images and point to them in your instruction — the edit lands on the look you show, not just the one you describe.
No Timeline, No Keyframes
Skip masks, rotoscoping, and render queues. If you can describe the edit in a sentence, the model can perform it.
How to Edit a Video with AI
Three steps from source clip to re-rendered MP4 — most edits finish in minutes.
- 1
Upload Your Clip
Drop in a source video between 3 and 15 seconds (up to 100MB). The output keeps its length and aspect ratio.
- 2
Describe the Edit
Write the change in plain language — "repaint this street as watercolor" or "swap the jacket for @Image1" — and attach reference images when the look is specific.
- 3
Generate & Download
The model re-renders every frame in minutes. Preview the result, download the watermark-free MP4, or iterate with a tweaked instruction.
AI Video Editor vs. Timeline Editor
They solve different problems: one changes the pixels inside your footage, the other arranges footage on a timeline.
| AI Video Editor (Molyin) | Timeline Editor | |
|---|---|---|
| Skill required | A sentence describing the change | Cutting, masking, keyframing, grading |
| Time per edit | Minutes — the model re-renders in one pass | Hours of manual work per shot |
| What it changes | The pixels themselves: styles, objects, outfits | The arrangement: cuts, transitions, overlays |
| Best for | Restyling and rewriting existing shots | Assembling multi-clip stories with precise cuts |
The two are complements, not rivals — many creators re-render shots on Molyin, then assemble them in a timeline.
What Creators Edit with AI
The same clip, re-rendered for a new audience, catalog entry, or creative direction — without a reshoot.
Restyle Social Clips
Re-render a phone clip as anime or watercolor and repost the same moment as something scroll-stopping.
Product Variants
Shoot one product video, then swap colors, materials, or the product itself for every variant in the catalog.
Ad Iteration
Test the same ad in different looks, wardrobes, and settings without reshooting a single frame.
Look Development
Preview a grade, an era, or an art direction on real footage before committing a production budget to it.
