Question 1

Which is better, Kling 3.0 or MiniMax H3?

Accepted Answer

Kling 3.0 scores higher on measured image-to-video quality, and Kling 3.0 is cheaper to run. If the two are different engines, that is the whole trade-off: pick Kling 3.0 while you are still iterating on an idea, and Kling 3.0 for the version you intend to publish.

Question 2

What does the quality score mean?

Accepted Answer

It is a normalised 0-100 rating derived from measured image-to-video preference testing, with audio excluded so it compares the picture rather than the soundtrack. It is a like-for-like comparison, not a marketing figure.

Question 3

Why does one bill per clip and the other per second?

Accepted Answer

Because that is how each is priced upstream. On a per-clip engine a four-second clip costs the same as an eight-second one, so longer scenes are better value. On a per-second engine you pay only for the length you use. The 'from (per second)' row above normalises both onto one axis so they can be compared.

Question 4

Can I switch engines partway through a project?

Accepted Answer

Yes. The engine is a setting, and the estimate updates when you change it. Clips already generated are not regenerated automatically, so a mid-project switch shows up in later scenes.

Question 5

Do both keep my characters consistent?

Accepted Answer

Yes, and by the same mechanism: every clip is image-to-video, so the approved still drives what appears. Both also accept reference images directly, though they differ in how many — which is the reference-images row above.
