About

Seedance 2.5 offers 4–30-second clips, output through 1080p, an audio switch and capacity for up to 30 image references. MiniMax H3 offers 5–15 seconds, output through 4K and up to nine references, with generated audio always included. Both use a single Standard tier and support the same four video input operations. A gradual camera passage may benefit from the longer supported duration; a short deliverable with a larger output requirement points to a different specification. These choices describe supported formats, while motion, identity and sound still need review in the actual result.

Questions

Which model supports a clip longer than 15 seconds?

Seedance 2.5 supports 4–30 seconds. MiniMax H3 supports 5–15 seconds. Choose the length the action needs; a longer supported duration does not guarantee that every scene stays coherent.

Which offers the higher output resolution?

The current MiniMax H3 menu reaches 4K and includes 480p, 720p and 2K. Seedance 2.5 offers 480p, 720p and 1080p. Output size alone does not establish better motion or subject fidelity.

Can I turn sound off on both?

Seedance 2.5 has an audio switch. MiniMax H3 always includes generated audio. Account for that difference if the clip will have a separate soundtrack.

How do references and start frames compare?

Both follow the image for image-led framing and support text, start-image, first/last-frame and reference operations. Seedance 2.5 supports up to 30 reference images; MiniMax H3 supports up to nine.

What should I inspect for a character scene?

Check identifying features, costume, proportions and motion across the full clip. Keep the same useful references and brief when comparing actual results, and record any different duration or output settings.
