Caption videos with an API: the cost on Sume per caption job
Captioning on Sume is a fixed price per caption job for videos up to the documented length, so a batch costs that price times the number of videos.
Captioning a video on Sume is a fixed price per caption job; the docs price it for videos up to 60 seconds under the current estimate and point to GET /v1/catalog for the live price. A batch of videos costs that price times the count.
Worked example: Caption 50 videos with an API: $10.00 on Sume
Captioning 50 videos on Sume costs $10.00: a fixed $0.20 per caption job. The docs price it for videos of 60 seconds at most, under the current fixed estimate, and point to GET /v1/catalog for the live price.
Source: Sume's video captions docs, read 2026-10-06. A restyle of an existing caption does not change the price, so styling experiments on the same job are not a new line item.
What does a month look like?
Captioning is one job per video.
| Videos | Cost |
|---|---|
| 50 | $10.00 |
| 100 | $20.00 |
| 200 | $40.00 |
What should I plan for?
Captions are one stage of finishing; trims, filters and the final render are billed separately.
- Keep each video at 60 seconds or less for the quoted price.
- Run captions after the final cut; a trim afterwards means a new caption job.
- Use
Idempotency-Keyper video so a retry does not double bill.
