Sume video captions: $0.20 a job, ten clips cost $2.00

Standalone Sume video captions cost $0.20 per accepted job, quoted for videos of 60 seconds or less, so ten clips cost 10 x $0.20 = $2.00. A restyle of an already captioned video is still a render and keeps the same price, but sending source_caption_id reuses the existing word timings, so speech-to-text does not run again.

The job is POST /v1/video-captions with a public HTTPS video_url, not a media.sume.com import. The price and the 60-second note are in the video captions docs; check the live number in the catalog.

Cost for a batch with restyles

Every accepted job reserves and captures $0.20. A restyle is its own job, so testing three looks on one clip is four jobs in total: the first caption plus three restyles.

Restyle without transcribing twice

Send source_caption_id and a new style instead of video_url. Sume reuses the source video and the stored word timings. Send words with it only to correct the text. Choices include slam, punch, tiktok-green, korean-ad and the Hangul styles; design overrides colors, typography, placement, phrasing and motion for one request, and bad values fail at request time with a 400, before any charge.

{
  "source_caption_id": "vc_123",
  "style": "black-outline",
  "design": { "colors": { "active": "#22D3EE" } }
}

Errors that save you a retry

Captions from speech need audible speech. A silent clip fails with caption_no_speech and next_action: use_overlay_captions; send cues with text, start and end to burn authored text. Korean text on slam, punch or tiktok-green returns 400 caption_hangul_text_latin_style. A script_text that cannot be aligned returns script_alignment_mismatch or script_alignment_failed; simplify the script or omit it.

• Send only one of script_text, words, cues and segments.
• video_url must be public HTTPS; localhost, private-network and signed or private links are rejected.
• SRT uploads are not supported; use cues for phrase-level text.

Planning a batch

Check durations before you submit. The $0.20 price is quoted for videos of 60 seconds or less under the current fixed estimate, so a 90-second clip is outside the number this page can back. Trim long clips first: a video trim is $0.02, so trim plus caption is $0.22 per clip, and 40 clips cost 40 x $0.22 = $8.80.

Use an idempotency key per clip so a retry after a network error does not create a second $0.20 job. Poll the job envelope at /v1/jobs/:id/status and /result, or read GET /v1/video-captions/:id, which returns the public-safe status, the style and the captioned video_url. Raw transcripts and renderer internals are not part of the public contract, so keep your own copy of any text you need.
