Upscale a 45-second clip: 30 s maximum, so two trims, $0.445

Sume Video Upscale 1.0 is $0.009 per video second with a maximum of 30 seconds, so a 45-second clip cannot go in as one job. Cut it into a 30-second part and a 15-second part with two video trim jobs, upscale each, and the bill is $0.04 + $0.27 + $0.135 = $0.445. Joining the two results back on Timeline 1.0 adds one render at $0.10 for a total of $0.545.

The line items

Each step has a public flat or per-second rate. Trim is $0.02 per job and the timeline render is $0.10 per output minute, rounded up to a whole minute with a one-minute minimum.

Why duration_seconds matters

If you do not send duration_seconds, Sume reserves 5 seconds, which is $0.045, then captures the actual cost. Sending it makes the hold match the job. The accepted range is 1 to 30 seconds, and the request also takes an upscale_factor of 1.1 to 4 and an enhancement_tier of fast, standard or pro.

• The 30-second cap is on the input, so a 31-second clip needs two jobs.
• Use exact precision on the trims so the parts meet at 30 seconds.
• The price is the same for every tier named in the request schema.

The first part

Trim the first 30 seconds, wait for the job, then pass its video_url to the upscale call.

Check before you scale up

A 30-second part at $0.27 is the most one job can cost. Try a 5-second part first at $0.045 to see the result, then run the full parts. The catalog gives a maximum job estimate of 27 cents before the Sume agent fee, which matches 30 x $0.009.

Scaling it up

For 20 such clips the bill is 20 x $0.445 = $8.90 without a render, and 20 x $0.545 = $10.90 with one render per clip. If the 45-second clip is cut at 22.5 seconds instead, both halves fit the limit and cost 45 x $0.009 = $0.405 in upscale either way, because the price is per second, not per job. Only the trim count and the reserve differ. Splitting evenly keeps each hold at $0.2025, rather than a $0.27 hold on one part.
