MiniMax H3 Max input video: billed per second, by resolution

On MiniMax's pay-as-you-go page, a reference video sent to H3 Max is billed by the input video's duration, at a per-second input rate that depends on the output resolution. The input rate is not the output rate: at 768P it is $0.143 per second against $0.08 for output, so a 10-second reference adds $1.43. Sume lists image, video and audio references for minimax-h3-max and reserves one amount on submit.

What are the H3 Max input-video rates?

The vendor page lists two H3 Max video-input lines, next to its output rows.

Which reference types does Sume list for H3 Max?

The video docs describe H3 Max as text-to-video, first/last-frame image-to-video and reference-to-video at 480p/768p/1080p (1080p is a latent refinement from native 768p) for 5-15 seconds, and say it reports image, video and audio supported_input_references. Reference support is per model: check the catalog before sending a reference type.

How does a reference video show up in the Sume price?

It does not appear as a separate line in the sources read here. Billing is the workspace USD balance, reserved on submit at provider list x 1.25, minimax-h3-max included, and the Video Router page says Sume bills list x 1.25 on every model. Look at the reserved amount on the job for a given request.
