One Whale, Three Video Models: MiniMax H3 vs Veo 3.1 vs Sora 2eric

Our homepage has an electric whale — a glowing cyan wireframe humpback swimming through a digital ocean — playing behind the headline. It was made for a wide desktop screen, so on a phone it gets cropped to a sliver. We wanted a proper portrait version for mobile, and it turned into a small experiment worth writing down: take one keyframe and hand it to three different video models — one running locally on our RTX 3060, and two frontier models in the cloud — then judge them honestly.

The twist, as usual, is that "cheapest," "best-looking," and "the one we actually shipped" were three different answers.

The setup: one keyframe, three animators

Everything starts from a single still. We generated a 9:16 keyframe on the same RTX 3060 that runs the rest of this series — a cyan low-poly wireframe whale over a glowing data grid, with a magenta flare and purple depth to match the original. Then that identical image went, unchanged, into each of the three models as the first frame. Same whale, same starting composition — only the motion model changes.

That is the fair way to compare image-to-video: hold the input constant and watch what each model does with it.

MiniMax H3 — local, free, and it actually works

First, the home team. MiniMax H3 is an open-weights model we already run locally, streaming its 50-odd GB of weights through a 12GB card a slice at a time.

The result is genuinely good: the whale swims with a real, gentle tail undulation and the model even grows its own drifting data-particles by the end. It is coherent, on-style, and it cost nothing but electricity and patience — about 20 minutes for a 3-second clip at 512×896. That is the honest local trade-off: free and completely private, but slow, shorter, and lower-resolution than the cloud. As a proof that a consumer card can do this at all, it's a quiet triumph.

Veo 3.1 — the calm, cinematic one

Next, Google's Veo 3.1 Fast, through the Gemini API, from the exact same keyframe.

This is where the jump in production value shows. In under a minute and for a dollar or two, Veo returned a smooth 720×1280, 8-second clip — and, unprompted, built an entire digital ocean around the whale: a rippling grid, parallax depth, drifting stars. The motion is calm and ambient, which matters when the video lives behind a headline. It never fights the text. This is the one we shipped.

Sora 2 — the most beautiful, and the one on a clock

Finally, OpenAI's Sora 2, same keyframe again.

On pure craft, Sora 2 makes the best whale of the three. The wireframe mesh is the most refined, and the motion is the most lifelike — a graceful full-body dive with fins and flukes that move like they have weight. It was also the cheapest of the cloud runs (~$0.80 for 8 seconds) and quick (~2 minutes).

There are two catches. First, that gorgeous, dramatic motion is busier — stunning as a hero, harder to sit quietly behind text. Second, and decisively for us: OpenAI's Sora 2 video API stops accepting requests on 24 September 2026. Building a banner on an API that disappears next week is not a plan.

A quick colour lesson

One thing the experiment taught us: image models have opinions. Our first keyframes came out pure cyan on black — the model kept stripping the magenta flare and purple wash that give the original its identity. No amount of prompting fixed it; the model simply preferred cyan. The fix was to stop arguing and composite the magenta back in — a flare and a purple gradient added to the keyframe in a few lines of code. Every model then faithfully carried that palette through the animation. Sometimes the right move is to give the model a picture, not an argument.

The verdict

| | Where | Best at | The catch | |---|---|---|---| | MiniMax H3 | Local, RTX 3060 | Free, private, no API | Slow, short, lower-res | | Veo 3.1 | Google, cloud | Calm, cinematic, ambient | Paid per second | | Sora 2 | OpenAI, cloud | Most beautiful, most lifelike | API shuts down 24 Sep 2026 |

If you want free and private, the local model already does it. If you want the most beautiful single clip, Sora 2 wins — for just a few more days. But for a banner that has to loop quietly behind a headline and still be regenerable next month, Veo 3.1 was the right tool — and it's the whale now swimming on our homepage when you open tyolab.com on your phone.

The best-looking model and the right one are rarely the same tool. We keep relearning that, one whale at a time.
