H3 Max lip sync resolutions on Sume: 480p, 768p, 1080p, no 2K
Sume's H3 Max lip sync offers 480p, 768p (default) and 1080p, no 2K. At the documented list times 1.25 that is $0.0625, $0.10 or $0.20 per second.
Sume's MiniMax H3 Max lip sync takes resolution of 480p, 768p (default) or 1080p, and refuses 2K. The doc's provider list is $0.05, $0.08 and $0.16 per second (fal page, 2026-09-22), and Sume bills ceil(duration_seconds) times that times 1.25, which works out to $0.0625, $0.10 and $0.20 per second. A 5 second clip at 768p reserves $0.50.
From docs/api/minimax-h3-max-lip-sync.md on origin/main b28f3b0 (read 2026-10-13); the per-second Sume figures are the doc's formula applied to its list rates.
| Resolution | Provider list per second | Sume per second | 5 s clip | 14.8 s clip (billed as 15 s) |
|---|---|---|---|---|
| 480p | $0.05 | $0.0625 | $0.3125 | $0.9375 |
| 768p (default) | $0.08 | $0.10 | $0.50 | $1.50 |
| 1080p | $0.16 | $0.20 | $1.00 | $3.00 |
Is the amount reserved or captured?
Both: the API reserves it at admit, captures it on completion and refunds it on failure. POST /v1/generation/admission-preview accepts the public id minimax/h3-max/lip-sync so you can see the amount first. The rate card id is fal_minimax_h3_max_lip_sync_2026-09-22.
Why would I pick 480p?
Cost and drafts: a 480p pass is 37.5% cheaper than 768p per second. Review the lip movement at 480p, then render the approved audio at 1080p. Keep the audio_url the same file so the waveform matches; the reservation uses duration_seconds, which must stay between 5 and 14.8.
