Mixer AI
Which generator fits: six models compared side by side
There is no single best AI video generator: the right one depends on the job. Seedance 2.5 and Gemini Omni edit finished footage, Seedance 2.5, Wan 3.0 and MiniMax H3 handle several shots in one prompt, and Kling 3.0 builds Multi-shot scenes.

Two tables below show what to pick for each task and what each of the six models can do.
Vertical close-up. A girl with long dark hair and closed eyes presses a black kitten to her cheek. She wears an orange jacket and mechanical cyborg arms with exposed wires. Plain light background. She slowly turns her head and nestles closer to the kitten, her expression calm and tender. The kitten lifts its head, ears pointing up. Static camera, soft diffused light, her hair stirring slightly.
How to choose
Define the job: a scene from text, an animated photo, a scene from references, several shots or an edit of finished footage.
Pick one or two models from the table below.
In the Mixer AI studio, open video, choose the model and the mode: text, frames, references or video.
Upload photos, video or audio within the model's limits.
Give each chosen model the same duration, resolution and aspect ratio and run a short test.
The price is shown before you start.
Compare movement, faces, props and sound.
Make the final version on the model that passed the test. Seedance 2.5 can render a 480p draft first and finish the good take in 1080p.
Test scenes for comparing models
0–3 s: wide shot, a cyclist rides around the corner onto a wet evening street lit by shop windows. 3–4 s: close-up, the wheel rolls through a puddle, water splashes. 4–7 s: medium side shot, the cyclist stops at a bakery door and takes off the helmet. Warm window light, sound of rain and tires on asphalt.
Keep the person, their movements, clothing and the camera work. Replace the background: instead of an office, a rooftop terrace at sunset with the city below, warm light falling on the face from the left. Same length and framing as the source video.
Which AI video model is best for your task
| Task | Model | Why | Keep in mind |
|---|---|---|---|
| Change the background, clothing or objects in finished footage | Seedance 2.5, Gemini Omni 1.2 | Only these two have an edit mode for uploaded video | Seedance 2.5 takes one 4–30 s video, Gemini Omni 1.2 up to 15 s; movement and framing come from the source |
| Extend an uploaded clip | Gemini Omni 1.2 | The only model that continues an uploaded video | Adds 3–10 s to a video up to 15 s long |
| Several shots in one clip | Seedance 2.5, Wan 3.0, MiniMax H3 by timecode; Kling 3.0 with Multi-shot scenes | No separate shot field is needed: shots can be written in the prompt by seconds | Shots of different framing last different times; Kling 3.0 Multi-shot allows up to 5 scenes, 3–15 s in total, sound on |
| Realistic people and facial acting | Seedance 2.5 | Keeps expressions that change during the scene and a chain of camera moves in one shot | It treats the start frame loosely: angle and pose may shift |
| The same character or object | Seedance 2.5, Wan 3.0, MiniMax H3, Kling 4.0 with references; Kling 3.0 with elements | Kling 3.0 elements are references too: up to 3 elements of 2–4 photos each | Each reference should add something: face, outfit, location |
| A line spoken from a recording | Wan 3.0, MiniMax H3, Seedance 2.5 | They accept audio as a reference | Wan 3.0 takes audio without a photo; MiniMax H3 and Seedance 2.5 only together with a photo or video |
| Motion graphics and animated text | MiniMax H3, Gemini Omni | MiniMax H3 more often renders on-screen words correctly; Gemini Omni keeps a palette set at the start of the prompt | Skin and faces in close-up look less natural with both |
| Movement through set frames | Kling 4.0 | Keyframes mode: up to 10 frames, up to 8 of them intermediate | Complex camera paths, fights and close interaction come out weaker |
| Inexpensive tests, cartoons and animation | Kling 3.0, Grok Imagine | Simple scenes and wide shots cost less on Kling 3.0; Grok Imagine is inexpensive and good for animation | Fast motion and crowds blur on Kling 3.0 |
The table matches models to tasks. Before starting, open the model's mode in the studio: the available fields and the price are shown before generation.

AI video models compared: what the six models can do
| Model | Duration | Resolution | References: photo / video / audio | Sound | Editing finished video |
|---|---|---|---|---|---|
| Kling 4.0 | 3–30 s | 720p, 1080p | up to 7 / up to 5 / none | Only the reference video's sound | No; keyframes available |
| Seedance 2.5 | 4–30 s | 480p, 720p, 1080p | up to 30 / up to 10 / up to 10, audio with a photo or video | Switch, on by default | Yes: one 4–30 s video |
| Wan 3.0 | 2–30 s | 480p, 720p, 1080p | up to 10 / up to 5 / up to 5, audio allowed without a photo | Switch, on by default | No |
| MiniMax H3 | 4–15 s | 768p, 2K | up to 9 / up to 3 / up to 3, audio with a photo or video | No switch in the form | No |
| Gemini Omni 1.2 | 3–15 s | 360p, 720p, 1080p, 4K | up to 10 / 1 up to 15 s / none | No switch in the form | Yes: video up to 15 s; extension by 3–10 s |
| Kling 3.0 | 3, 5, 10 or 15 s | Standard 720p; Pro 1080p and 4K | up to 3 elements of 2–4 photos plus a start frame / none / none | Switch; always on in Multi-shot | No |
Gemini Omni 1.1 and 1.0 Flash make 4, 6, 8 or 10 s clips and edit a segment up to 10 s. There is no speech language setting: the language follows the text of the line.
First choose how you will control the scene
| Your task | What to prepare | What to check in the model | What to judge in a short result |
|---|---|---|---|
| Animate an existing photo | A sharp source image and one movement | A start-image mode | Appearance, object shapes and background stay intact |
| Create a scene without a photo | A description of the character, action, place and camera | A text-to-video mode | Clear action and a consistent scene |
| End the scene on a set composition | Matching first and last frames | Two-frame support in the chosen mode | Smooth movement between start and end |
| Repeat a specific movement | A permitted reference video and an image of the character | Motion control, not just video upload | The main movement matches without losing appearance |
A model name alone does not answer these questions. Open the settings of the chosen mode and check the input files before starting. Do not compare minimum prices across different durations and resolutions.
Best AI video generators: how to compare them yourself
Run the same scene on two models with the same duration, resolution and aspect ratio. You will see the difference in movement and faces, and the prices are compared on equal terms.
Look at what breaks most often: a face turning, hands, objects that should stay in place, and whether a line lands on time.
Ready-made side-by-side comparisons of Kling 3.0 and Kling 4.0, Seedance 2.5 and Wan 3.0, MiniMax H3 and Seedance 2.5, Seedance 2.5 and Gemini Omni are in the Related guides block at the bottom of the page.

FAQ
What is the best AI video generator?
No single model is best for every task. For editing finished footage choose Seedance 2.5 or Gemini Omni, for several shots in one prompt Seedance 2.5, Wan 3.0 or MiniMax H3, for Multi-shot scenes Kling 3.0.
Which AI makes the longest video?
Seedance 2.5, Wan 3.0 and Kling 4.0 produce up to 30 seconds per generation. MiniMax H3 and Gemini Omni 1.2 go up to 15 seconds, Kling 3.0 offers 3, 5, 10 or 15 seconds.
Which AI can edit an existing video?
Seedance 2.5 and Gemini Omni. Seedance 2.5 takes a 4–30 second clip, Gemini Omni 1.2 up to 15 seconds and can also extend an uploaded clip by 3–10 seconds.
Which AI video generator adds sound?
Seedance 2.5, Wan 3.0 and Kling 3.0 have a sound switch, on by default for Seedance and Wan. Kling 4.0 can keep the sound of the reference video; MiniMax H3 and Gemini Omni have no switch in the form.
Should the first attempt use maximum resolution?
No. Test action and composition first. More pixels will not fix an incorrect path, face or object interaction.
