Picking an AI video model is mostly a question of what the clip has to do. Some shots need to look expensive. Some just need to exist by tomorrow. And some need to sound right the first time, because you are not going to score them afterwards.
GenPix runs several video models behind one prompt box. This guide compares the three you will reach for most often — Seedance 2.0, Kling 3.0, and MiniMax H3 — and explains when each one is the right call.
The short answer
| Seedance 2.0 | Kling 3.0 | MiniMax H3 | |
|---|---|---|---|
| Best for | Cheap drafts and quick tests | Cinematic shots, high motion | Sound-led clips, fast turnaround |
| Resolution | 480p / 720p | 720p / 1080p / 4K | 768P / 2K |
| Clip length | 4–15 seconds | 3–15 seconds | 4–15 seconds |
| Aspect ratios | 16:9, 9:16, 1:1, 4:3, 3:4, 21:9 | 16:9, 9:16, 1:1 | 21:9, 16:9, 4:3, 1:1, 3:4, 9:16 |
| Audio | Generated with the picture | Generated with the picture, toggleable | Native stereo, always on |
| Reference input | One first-frame image | One first-frame image | One first-frame image |
| Cost for a 5s clip | 59 credits (480p) / 124 (720p) | 70 credits (720p, no audio) / 135 (1080p with audio) | 40 credits (768P) / 65 (2K) |
Credits are charged per second of output. See pricing for how credits map to plans.
Seedance 2.0 — the one to draft with
Seedance 2.0 is the cheapest way to find out whether an idea works. It outputs 480p or 720p, in clips from 4 to 15 seconds, and a 5-second 480p take costs 59 credits — roughly a third of what a 1080p Kling shot runs.
That price changes how you work. Instead of carefully composing one prompt and hoping, you can generate three or four directions, watch them, and only then commit to a final render on a heavier model. The cost of being wrong drops to almost nothing.
Reach for it when:
- You are still deciding what the shot should be.
- You need a rough cut to show someone for feedback.
- The clip is going to be re-rendered later anyway.
Skip it when the final output has to be 1080p or higher, or when the shot depends on fine detail and texture — 480p will not hold up.
Kling 3.0 — the one for shots that have to look expensive
Kling 3.0 is built for camera work. It plans the shot itself from your description — how close the camera sits, when it pushes in, where the cut lands — rather than treating your prompt as one static frame. High-motion scenes hold together: running, chases, and choreography keep the camera, subject, and environment in the right spatial relationship where weaker models fragment.
It is also the only model here that outputs native 4K at generation time, rather than upscaling a smaller render. Detail and encoding stay clean, which matters if the clip is going on a large screen or into a finished edit.
Audio is generated with the picture and can be switched off if you plan to score the clip yourself.
Reach for it when:
- The shot has to move — push-ins, arcs, whip pans, tracking.
- You need 1080p or 4K output.
- You are shooting a vertical ad and want a strong camera beat.
Skip it when you just need a fast, cheap take. A 5-second 720p clip without audio is 70 credits; the same idea on Seedance 2.0 at 480p is 59 credits for a longer, cheaper experiment.
MiniMax H3 — the one that arrives with sound
MiniMax H3 generates picture and audio in the same pass. Dialogue, ambience, foley, and music are produced alongside the frames — not dubbed on afterwards — and audio is not charged as an extra. There is no audio toggle because there is nothing to toggle: sound is part of the output.
It outputs 768P or 2K, runs 4 to 15 seconds, and covers the widest set of aspect ratios of the three, from ultrawide 21:9 through to vertical 9:16.
At 768P a 5-second clip is 40 credits — the cheapest audio-native option here. If your clip needs to sound finished and you do not want a separate audio step, this is usually the one.
Reach for it when:
- The clip has to ship with sound.
- You want 2K without paying 4K prices.
- You need an unusual ratio like 21:9 or 3:4.
Skip it when the shot depends on aggressive camera movement, or you need 4K — Kling 3.0 is the better tool there.
How to choose in ten seconds
- Drafting or testing an idea? → Seedance 2.0.
- The shot has to move, or you need 1080p/4K? → Kling 3.0.
- Sound matters and you want a low per-second rate? → MiniMax H3.
- Need up to 30 seconds in one clip? → Seedance 2.5, the flagship, supports the longest takes.
A note on prompting
All three respond better to shot language than to adjectives. Instead of "a beautiful cinematic scene", describe what the camera does and what the viewer hears:
"Slow push-in from the doorway. Rain on the glass, low traffic hum outside. The subject turns toward the window as the light shifts."
That sentence gives the model a camera move, a subject action, and a sound bed. It works on all three — the difference is only in how each one renders it.
Frequently asked questions
Can I use my own image as the first frame? Yes — all three models accept one image as the opening frame. The clip follows the aspect ratio of your image.
Do I need to know how to edit video? No. Describe the shot, pick a length and resolution, and generate.
Why is 4K only available on Kling 3.0? Because Kling is the only model here that produces 4K natively at generation time rather than upscaling. That capability is why it costs more per second.
Which one is cheapest? MiniMax H3 at 768P is the cheapest audio-native option (40 credits for 5 seconds). Seedance 2.0 at 480p is the cheapest silent option (59 credits for 5 seconds).
