MiniMax H3 vs Kling Video v3 Pro (Text)
Generated on PixelDojo. Produced by PixelDojo's generation pipeline.
MiniMax H3 costs 3 credits per second and Kling Video v3 Pro (Text) costs 8 credits per second, so pick MiniMax H3 when you already have a photo to animate and want the cheaper rate, and pick Kling Video v3 Pro (Text) when you have no source image and need a Pro-tier text-to-video render at an exact aspect ratio. We sent the same product-orbit wording to both on August 26, 2026. MiniMax H3 animated an earbuds product photo for 15 credits in about 205 seconds. Kling Video v3 Pro (Text) generated a clip from that same wording with no photo attached at all, for 24 credits in about 215 seconds.

Kling Video v3 Pro (Text)
Same orbit wording, both run August 26, 2026. MiniMax H3: 15 credits, about 205 seconds, from a photo. Kling Video v3 Pro (Text): 24 credits, about 215 seconds, from text alone.
How It Works
How we ran the comparison:
Feed each model the input it actually supports
MiniMax H3 got an earbuds product photo as a start frame for image-to-video. Kling Video v3 Pro (Text) got the same wording with no image at all, since this apiId only accepts a prompt.
Run each at its cheapest duration
5 seconds for MiniMax H3, the minimum it accepts. 3 seconds for Kling Video v3 Pro (Text), its minimum.
Time it and read the bill
We bracketed each request with a timestamp at submission and at the finished asset, then recorded the exact credits charged.
The Pixel Dojo Advantage
| Others | Pixel Dojo |
|---|---|
| Price model | MiniMax H3 is 3 credits per second at its 2K tier, or 2 credits per second at 768p, but the cheaper tier only applies to a pure text-to-video call with no image. Kling Video v3 Pro (Text) is a flat 8 credits per second across its whole range, with no lower tier available under this apiId. A standard-tier Kling text-to-video apiId exists separately at 6 credits per second. |
| What we measured | MiniMax H3: 5 second image-to-video clip, 15 credits, about 205 seconds, 1440x1440 output. Kling Video v3 Pro (Text): 3.04 second text-to-video clip, 24 credits, about 215 seconds, 1920x1080 at 24fps, 4.1MB file. |
| Input required | We fed MiniMax H3 an earbuds product photo as the start frame, its image-to-video mode. Kling Video v3 Pro (Text) only accepts a prompt under this apiId; there is no image field to fill. Animating an existing photo on Kling Pro means switching to the separate kling-video-v3-pro-image apiId. |
| Resolution and aspect ratio | MiniMax H3's image-to-video mode inherits the shape of the source photo and ignores any aspect ratio setting once an image is attached, which is why our square product photo came back as a square 1440x1440 clip. Kling Video v3 Pro (Text) has no source image to inherit from, so it renders whatever aspect ratio you request. Ours came back a full 1920x1080 at the 16:9 we asked for. |
| Duration range | MiniMax H3 runs 5 to 15 integer seconds. Kling Video v3 Pro (Text) runs 3 to 15 seconds, a lower floor for a quicker, cheaper test clip. |
| Native audio | Both list native audio generation. Our MiniMax H3 file carried a confirmed AAC audio track running the length of the clip. Kling Video v3 Pro (Text) defaults its generate_audio setting to true in the schema, though we did not separately probe our test file's track the way we did for MiniMax H3. |
| Which to pick | Use MiniMax H3 when you already have a photo to animate and want the lower per-second rate and confirmed audio. Use Kling Video v3 Pro (Text) when you have no source image yet, need Pro-tier text-to-video, and want an exact aspect ratio rather than one inherited from a photo. |

Common Questions
Everything you need to know about MiniMax H3 vs Kling Video v3 Pro (Text)
What does MiniMax H3 cost compared to Kling Video v3 Pro (Text)?
MiniMax H3 is 3 credits per second at its 2K tier, so a 5 second image-to-video clip runs 15 credits. Kling Video v3 Pro (Text) is a flat 8 credits per second with no lower tier, so a 3 second clip runs 24 credits.
Which one is faster?
In our August 26, 2026 run, MiniMax H3 took about 205 seconds for a 5 second clip and Kling Video v3 Pro (Text) took about 215 seconds for a 3 second clip. Neither the shorter length nor the lower price bought a faster turnaround here.
Can Kling Video v3 Pro (Text) animate an existing photo?
No. This apiId only takes a text prompt. Animating a photo on the Pro tier means using the separate kling-video-v3-pro-image apiId, priced the same 8 credits per second.
Does either model generate its own audio?
Both support native audio in their schema. Our MiniMax H3 file came back with a confirmed AAC track running the full clip length. Kling Video v3 Pro (Text) defaults audio generation to on, though we did not separately verify our test file's track.
I have no product photo yet. Which should I use?
Kling Video v3 Pro (Text). It needs nothing but a prompt and honored our requested 16:9 aspect ratio exactly, returning a full 1920x1080 clip. MiniMax H3 needs a start frame to run image-to-video at all.
How do I call these from the API?
Same key, same request shape for both. POST to /api/v1/models/minimax-h3/run with a prompt and optionally image_url, or to /api/v1/models/kling-video-v3-pro-text/run with a prompt and a duration between 3 and 15.
