Game teaser in 15 seconds: H3 Max start and end frame for $1.50

Two key-art frames, the start and the end of a scene, become a 15-second teaser for $1.50 on MiniMax H3 Max at 768p ($0.10 per second) on Sume. The same request at 1080p costs $3.00, and a 480p draft costs $0.9375.

Both MiniMax models list a start and end frame; only H3 Max also has a 1080p row. Prices come from the Sume price tool (read 2026-10-09).

Price of 15 seconds by resolution

A draft at 480p costs $0.9375. If the motion between the two frames is wrong, you find out for $0.5625 less than the 768p try.

The request body

Send the first frame as image_url and the last as end_image_url on the Video Router, with duration between 5 and 15. The prompt describes the move between the frames, not the frames.

Shorter teasers and higher resolution

Not every teaser needs 15 seconds. The table shows H3 Max at three lengths and two resolutions so you can pick the length before you pay for the resolution.

Limits and gotchas

H3 Max always produces native stereo audio, so mute or replace it if the trailer carries its own score.

• end_image_url needs an image_url: a last frame alone is refused.
• Duration is 5-15 seconds. A 20-second teaser needs a second job.
• 1080p on H3 Max is a refinement of native 768p. Inspect the first frames of a 1080p image-to-video clip before you assemble the trailer, because the catalog notes that some outputs show a size jump after two frames.
