100 AI video clips with H3 Max: cost by length and plan

A 768p H3 Max clip is $0.10 per second on Sume, so 5, 10 and 15 second clips cost $0.50, $1.00 and $1.50, and 100 of them cost $50, $100 and $150. The Pro plan includes $40 of usage, enough for 40 ten-second clips; Startup includes $140 (140 clips); Scale includes $800 (800 clips).

Per-clip math

H3 Max accepts 5 to 15 seconds. The 768p rate is the $0.08 list in the Sume docs times 1.25 = $0.10 per second. fal's pricing page lists H3 Max at $0.05 per second for its base figure (read 2026-10-07); that matches the 480p list in the Sume docs, so for a cheaper draft you can drop to 480p at $0.0625 per second.

How many clips fit in each plan

The plan catalog gives included usage per month: Pro $40, Startup $140, Scale $800. Dividing by the clip price gives the clip count. For a 10-second 768p clip ($1.00) that is 40, 140 and 800 clips. For a 5-second clip ($0.50) it doubles to 80, 280 and 1,600. For 15 seconds ($1.50) it is floor(40 / 1.5) = 26, floor(140 / 1.5) = 93 and floor(800 / 1.5) = 533.

What 100 clips means for each plan

A 100-clip, 10-second batch is $100 of usage. On Pro that is $40 included plus $60 more; Startup covers it with $40 left over; Scale covers it with $700 left. Sume's pricing docs says usage is billed at each model's published rate and that a team wallet can be funded with on-demand purchases from $10 to $1000. I am not claiming anything about rollover of unused included usage; check the dashboard Subscription page for that.

Resolution changes the answer more than length

Going from 768p to 1080p doubles the per-second price ($0.10 to $0.20), which is the same cost as doubling the clip length. If the clips go to a 9:16 feed that plays at phone size, 480p drafts at $0.0625 per second cut the 100-clip, 10-second bill from $100.00 to $62.50 before you spend on finals.

A mixed batch

Real batches are rarely one length. Take 40 clips at 5 seconds, 40 at 10 seconds and 20 at 15 seconds, all at 768p. The cost is 40 x $0.50 = $20.00, plus 40 x $1.00 = $40.00, plus 20 x $1.50 = $30.00, for $90.00 across 100 clips. The average is $0.90 per clip and 9 seconds of video per clip.

That $90.00 fits inside Startup's $140 of included usage with $50.00 to spare, and it is $50.00 over Pro's $40. If you run the same mix twice in a month, the second pass spends the Startup remainder: $50.00 left covers 55 more clips of the same mix. Work out the remaining balance before you queue the second batch: a job whose reservation the balance cannot cover is refused with a 402.
