The Best AI Video-to-Video Generators in 2026

Key Takeaways

• Magejutsu on Mage is our top pick for video-to-video. It keeps a clip's motion, camera, cuts, timing, and sound, and swaps in your characters, places, or products, on sources of 4 to 30 seconds at up to 1080p.

• Magejutsu works in 2 modes. Motion transfer rebuilds who performs the clip, and object swap changes only what your references point at.

• Source limits vary a lot. Runway's Aleph 2 takes 2 to 30 seconds, Beeble's SwitchX 3.0 tops out at 360 frames, and Magejutsu Lite and Feather take up to 15 seconds.

• One app covers recasting and object swaps. Magejutsu comes in 3 models, Magejutsu, Lite, and Feather, so you can trade quality for speed and cost on the same clip.

What Is the Best AI Video-to-Video Generator?

The best AI video-to-video generator changes what's in your clip and leaves the rest alone, including the performance, the camera move, and the sound. On Mage, that's Magejutsu, a Mage exclusive that edits a video you already have instead of generating a new one.

The 6 tools below all start from footage. They split on what they can change, how long a source they take, and whether your original sound survives the edit.

What Sets a Good Video-to-Video Generator Apart

Whether you're putting a character into a dance clip or changing the product in an ad, start with these checks.

The performance survives

The motion, timing, and camera are why you're starting from footage. A good tool changes the subject without redoing the shot.

It can swap anyone or anything

Some tools only restyle. Others can replace a person, an outfit, a product, or a place, which covers far more jobs.

Source length it accepts

Most social clips run under 30 seconds, and the caps here run from about 10 to 30 (check before you trim).

Sound kept or rebuilt

Keeping the original audio saves a step in the edit, and not every tool does it.

What an edit costs

Edits are usually priced per second of source, so a long clip on a pricey model adds up fast.

The Top 6 AI Video-to-Video Generators in 2026

1. Magejutsu - by Mage

Mage launched Magejutsu on October 31, 2026, as a new way to recast any video with your characters, places, and products. Give it a clip and photos of who or what should be in it, and it rebuilds the cast or swaps one thing while the motion, camera, cuts, timing, and sound stay as filmed.

What it does well:

• Motion transfer rebuilds who performs a clip, and object swap changes only what your references point at

• Sources of 4 to 30 seconds, with the result matching the source's length and shape

• Output at 480p, 720p, or 1080p

• Up to 30 reference images for characters, outfits, props, and places

• A director model watches your clip first and writes the edit, so directions are optional

• Greater creative freedom, especially on Magejutsu Lite

• No subscription is required, so you can generate with Magejutsu on a free plan

Magejutsu comes in 3 models that take the same inputs. Magejutsu gives the strongest recasts on sources up to 30 seconds. Lite is faster and cheaper on sources up to 15 seconds. Feather is the cheapest and fastest, for motion transfer at up to 720p. Start from your own clip, one of your creations, or a clip from the motion library, and it runs in the browser or through the Mage application programming interface (API). The Magejutsu docs cover every mode and model.

For edits that don't swap anyone, such as a change of weather or wardrobe across a whole clip, Mage's Video Editor edits a video from a prompt on Lemon, Cherry 2 Pro, and other models.

The catch: Magejutsu is billed in Gems on every plan, priced by your clip's length and the resolution you pick.

Best for: creators who want to change who or what is in a clip and keep everything else as filmed.

2. Aleph 2 - by Runway

Runway launched Aleph 2 inside Edit Studio on May 21, 2026. It makes localized and image-referenced edits to an existing clip, from swapping a product to changing the background, lighting, or time of day.

What it does well:

• Sources of 2 to 30 seconds, at 480p to 1080p

• Clips with up to 10 cuts

• Edits that carry across every shot of a multi-cut clip, with an image preview before generating

Aleph 2 costs 28 credits a second, with a 56-credit minimum, and you pay only for the range you edit. Standard costs $15 a month for 625 credits, which is about 22 seconds of Aleph 2.

The catch: Edit Studio is on paid plans only, and ProRes export is limited to Max, Enterprise, and legacy Unlimited plans.

Best for: editors who want prompt edits on a short shot.

3. Kling VIDEO 3.0 Omni - by Kuaishou

Kling's VIDEO 3.0 Omni model edits a video you upload, from replacing a subject or object to restyling the whole clip by prompt.

What it does well:

• Subject and object replacement

• Whole-video restyles from a prompt

• 720p and 1080p modes

With video input, Kling charges 16 credits a second at 1080p and 12 at 720p.

The catch: Kling's guide says native audio isn't supported yet with video input, and its source limit is 3 to 10 seconds in the guide and 3 to 15.5 seconds in the API docs.

Best for: Kling users who want edits on the same credits as generation.

4. SwitchX - by Beeble

Beeble's SwitchX changes the background, lighting, and style of a video while keeping the subject's performance.

What it does well:

• 720p and 1080p on Creator, 4K on Professional

• 10-bit MOV export on Professional

• Related tools for 3D relighting and background removal

SwitchX costs 6 credits a second at 720p and 20 at 1080p. Creator is $19 a month for 540 credits, and the free monthly credits don't cover SwitchX.

The catch: SwitchX 3.0 clips top out at 360 frames, or 12 seconds at 30fps (480 frames on SwitchX 2.0).

Best for: filmmakers relighting a shot or moving it to a new location.

5. Ditto - by Melius

Melius runs many third-party models on a node-based canvas, with a multi-track editor for assembling clips. Its Ditto model replaces characters, props, and backgrounds in an existing video from reference images.

What it does well:

• Up to 30 replacements in one generation

• Keeps the source audio by default

• Kling 3.0 Omni and Luma Ray 3.2 edits on the same canvas

Melius has a free tier, and Creator costs $20 a month, or $17 billed yearly, for 20,000 credits.

The catch: Ditto's source length limit and per-edit price aren't published.

Best for: teams who want edits inside a larger node-based workflow.

6. Video Restyle - by Krea

Krea's Video Restyle runs video-to-video style transfer on Luma's Modify model, and its Motion Transfer moves the motion from a source video onto a character.

What it does well:

• Restyles from a prompt

• Motion Transfer on Kling Motion Control v3

• Free daily units to test with

Krea gives free accounts 100 units a day, and paid plans start with Basic.

The catch: Krea doesn't publish source length or resolution limits for Restyle.

Best for: quick restyles alongside image work in Krea.

Recasting a Clip With Magejutsu

Step 1: Open Magejutsu and upload a clip of 4 to 30 seconds, pick one of your creations, or press Remix on a clip in the motion library.

Step 2: Add your references, such as a saved Character, an outfit, a product, or a place. One clear, front-lit photo per person is enough.

Step 3: Leave the directions to the director, or write your own. Here's an example from Mage's Magejutsu docs:

Replace the dancer with image 1, keeping the choreography, the camera move and the timing exactly as filmed.

Step 4: When the clip has more than one person, map each reference by position, such as "image 1 is the person on the left."

Step 5: Pick Magejutsu, Lite, or Feather, check the Gem price on the Generate button, and generate.

Motion Transfer or Object Swap?

Magejutsu's 2 modes cover different jobs, and Magejutsu sets up the source for whichever you pick.

Motion transfer keeps the motion, camera, cuts, and timing, and rebuilds who performs it, plus the place if you send one. Use it to put your character into a dance, a trend, or a scene from your own short film.

Object swap changes only what your references point at and keeps every other part of the shot as filmed. Use it to change the product in an ad, an outfit, or a prop without touching the performance.

Both keep the source's own audio, restored after the render, and both work with up to 30 references. Feather is motion transfer only, so pick Magejutsu or Lite for an object swap.

AI Video-to-Video Questions

What is the best AI video-to-video generator?

Magejutsu on Mage, because it keeps the original motion, camera, timing, and sound while it swaps in your characters, places, or products, on sources up to 30 seconds at up to 1080p.

What's the difference between video-to-video and image-to-video?

Image-to-video animates a still image. Video-to-video starts from footage and changes what's in it, so the original motion and timing carry over.

How long can the source video be?

Magejutsu takes 4 to 30 seconds, and Lite and Feather take up to 15. Runway's Aleph 2 takes 2 to 30 seconds, and Beeble's SwitchX 3.0 takes up to 360 frames.

Does Magejutsu keep the original audio?

Yes. The source's own audio is restored after the render.

Can I replace a product in a video with AI?

Yes. Magejutsu's object swap mode changes only what your references point at, such as a product or prop, and keeps the rest of the shot as filmed.

How much does Magejutsu cost?

Magejutsu is billed in Gems on every plan. The price follows your clip's length and the resolution you pick, and the Generate button shows the total before you start.
