Seedance 2.0 vs MiniMax H3: Which One to Use

Two models sit behind the picker on Video Gen Now: Seedance 2.0 and MiniMax H3. They are not ranked — they are shaped differently, and picking the wrong one for a job costs you either quality or credits.

Here is what actually separates them, with the numbers.

The short answer

• Need sound, 4K, or a clip shorter than five seconds → Seedance 2.0.
• Need 2K on a flat, predictable price, especially for longer or wider shots → MiniMax H3.

If you only remember one thing: Seedance is billed by pixels, MiniMax is billed by the second. Everything below follows from that.

What about Seedance 2.5?

Short version: Seedance 2.5 is not in the picker yet, and Seedance 2.0 is still the right answer today.

ByteDance announced Seedance 2.5 on 23 June 2026 at its Volcano Engine FORCE conference and launched it inside its own consumer apps on 31 July 2026. The headline claims are a big step up: single-shot clips up to 30 seconds instead of 15, 4K output, up to 50 multimodal references (images, video, audio and text rather than images alone), and region-level editing that changes part of a frame without re-rendering the whole clip.

What has not happened yet, as of 3 August 2026, is the part that matters for us:

• No open API. The Volcano Engine Ark endpoint was slated to open in early August and is not callable yet. Every model on Video Gen Now runs through a provider API, so until that lands there is nothing to connect.
• No published rate card. ByteDance said pricing would ship with the model card and it has not. Token rates surfaced through Volcengine and BytePlus give a rough shape, but nothing we would base a credit price on.

When it does arrive, it will show up in the model picker with a credit cost calculated the same way as everything else — from the real provider cost, shown before you submit. Nothing about your prompts or your library changes. Until then, the comparison below is between the two models you can actually render with today.

What each model gives you

Seedance 2.0 (ByteDance's flagship)

• Resolutions: 480p, 720p, 1080p and 4K
• Durations: 4, 5, 6, 8, 10, 12 and 15 seconds
• Aspect ratios: 21:9, 16:9, 4:3, 1:1, 3:4, 9:16
• Native audio — sound effects, ambience and lip-synced speech generated from the same prompt, at no extra cost
• Modes: text to video, image to video, reference to video (up to 9 reference images)

MiniMax H3

• Resolution: 2K on every mode
• Durations: 5, 6, 8, 10, 12 and 15 seconds
• Aspect ratios: the same six, plus an auto option in reference mode that follows your inputs
• No audio track — the clip comes out silent
• Modes: text to video, image to video, reference to video (up to 9 reference images)
• Unusually stable subject motion — faces and products drift less across a long take

What a clip actually costs

Credits track the real GPU cost of a render, so the two models price along different axes. A five-second 16:9 clip:

• Seedance 2.0 — about 68 credits at 480p, 152 at 720p, 341 at 1080p, 778 at 4K
• MiniMax H3 — about 130 credits, at 2K, whatever the aspect ratio

Read that twice, because it is the least intuitive thing about the two models: MiniMax at 2K costs less than Seedance at 720p. If your shot does not need audio, MiniMax is often the cheaper way to a high-resolution take.

The comparison flips as the shot gets wider or longer:

• Aspect ratio only moves Seedance. More pixels, more credits — a five-second 1080p clip is about 447 credits at 21:9 and about 192 at 1:1. MiniMax charges the same 130 credits for both, because it bills per second.
• Duration scales linearly for both. A ten-second MiniMax clip is about 260 credits; ten seconds of Seedance at 1080p is about 682.
• Reference images are free up to a point. MiniMax includes five reference images, then charges a small amount per extra one — nine images on a five-second clip lands around 162 credits.

Every one of these numbers is shown in the generator before you submit, so nothing here needs to be memorised. And if a render fails, the credits go straight back to your balance.

Where Seedance 2.0 wins

You need sound. This is the clean win. MiniMax renders silent, so if the deliverable is a spot that has to carry ambience, a whoosh, or a line of dialogue, Seedance does it in one pass from the same prompt. Adding audio afterwards means an edit session you were trying to avoid.

You need 4K. For a hero shot on a landing page or anything that will be cropped in post, 4K gives you room. It is the most expensive option on the platform at roughly 778 credits for five seconds — but the per-pixel rate is actually lower than 1080p, so it is better value than the raw number suggests.

You are drafting. 480p at about 68 credits is the cheapest render available. When you are testing whether a camera move reads at all, that is the resolution to iterate at — then re-render the winner once at 1080p. See the prompt guide for how we structure that loop.

Your clip is four seconds. Seedance goes down to four seconds; MiniMax starts at five. For a snappy social cut, that one second is real money and real pacing.

Where MiniMax H3 wins

Predictable budgets. Flat per-second pricing means a producer can quote a video before anyone has decided on the aspect ratio. With pixel-based billing, switching from 1:1 to 21:9 more than doubles the cost of the same shot.

Wide and vertical at high resolution. A 21:9 anamorphic take at 2K costs the same as a square one. If your campaign lives in cinematic ratios, this is where the difference shows up on the invoice.

Long takes. Fifteen seconds at 2K for roughly 390 credits is hard to beat if you do not need audio. The same duration on Seedance at 1080p runs past 1,000.

Subject consistency. In reference to video, MiniMax holds a face or a package steady across a long take better than we see elsewhere, and it accepts an auto aspect ratio that follows your uploads rather than forcing a crop.

One thing to watch in reference mode

Seedance handles reference-to-video on a faster, cheaper tier — around 121 credits for a five-second 720p clip — but that tier caps at 720p. If you need reference-driven video above 720p, MiniMax is the only option, and at 2K for about 130 credits it is barely more expensive than the capped Seedance render.

Picking by job

• Product ad for paid social — Seedance, image to video, 1080p, with native audio. Render the 9:16 and 16:9 cuts from the same prompt; at equal resolution they cost the same.
• Content-calendar filler, no budget for a shoot — MiniMax at 2K. Cheap per clip, no cropping surprises, silent by design because the platform will lay music over it anyway.
• Storyboard or client pitch — Seedance at 480p. You are selling the motion, not the pixels, and you want to render ten variations in an afternoon.
• Character or product that must stay recognisable — reference to video on MiniMax if you need the resolution, Seedance if you need the audio.

Questions people ask

Can I switch models mid-project?

Yes. The model picker sits on the same page as the prompt box, and your library keeps every render alongside the prompt that produced it, so you can re-run the same prompt on the other model and compare them side by side.

Does a higher price mean a better clip?

No. Price tracks pixels and seconds, not taste. A well-prompted 480p Seedance draft will beat a vague 4K render every time — the prompt is doing more work than the resolution.

Do both models support image to video?

Both do. One difference: MiniMax takes the output aspect ratio from your uploaded frame, so there is no ratio selector in that mode, while Seedance lets you choose one.

What happens when a new model is added?

It appears in the picker without changing how you work — same prompt box, same library, same credits. Pricing for a new model follows the same rule: credits track its real cost.

Can I render with Seedance 2.5 here yet?

Not yet. It launched in ByteDance's own apps on 31 July 2026, but the public API has not opened, so no third-party platform can serve it. We will add it as soon as the endpoint and its pricing are live — this post gets updated when that happens.

Takeaways

• Seedance 2.0 for audio, 4K, four-second clips, and cheap 480p drafting.
• MiniMax H3 for 2K at a flat per-second price, wide ratios, long takes, and reference shots above 720p.
• Seedance 2.5 is announced but has no open API or published pricing yet — it joins the picker when it becomes renderable.
• The generator shows the credit cost before you submit, and refunds anything that fails.

Try the same prompt on both — open the generator, render once on each, and let the footage decide. Plans and credit bundles are on the pricing page.
