How Sume rounds video cost to credits: why 5 s is 32, not 31.25

Sume rounds each job's estimate up to a whole cent before reserving, so a 5 second MiniMax H3 Max clip at 480p, which is 5 x $0.0625 = $0.3125, reserves 32 credits rather than 31.25. The rounding is per job, which means ten such clips reserve 320 credits, not 313.

The estimator applies the 1.25 house margin to the provider list that the Video Router docs describe, then rounds the billable USD amount up to cents (the code calls this the ceil of cents). Credits shown in the dashboard track those cents.

Rounding by example

These values come straight from running Sume's estimators.

Why per-job rounding matters in a batch

Because every job rounds up on its own, one hundred 5 second 480p H3 Max clips reserve 100 x 32 = 3,200 credits ($32.00) against an unrounded $31.25. The gap is at most one cent per job, so it is a rounding effect and only visible in big batches of cheap clips.

Reservations and captures follow the generation admission rules: reserve at submit, capture on success, release or refund on failure.
