Kapwing Business $50 or $64 vs 250 to 320 Sume caption jobs

Kapwing Business is cheaper per minute of subtitles at volume, and Sume is cheaper below about 250 clips a month. Kapwing lists Business at $64 a month, or $50 a month on annual billing, with 4,000 AI credits that its page says cover auto-subtitling up to 4,000 minutes. A standalone Sume caption job is $0.20 for videos up to 60 seconds, so $64 buys 320 jobs and $50 buys 250.

The break-even depends on clip length. A 60-second clip uses a full job at $0.20 on Sume and one credit-minute at Kapwing; a 15-second clip uses a full job on Sume but a quarter of that on a minutes meter.

The arithmetic

Per minute of 60-second clips, Kapwing Business is $64 / 4,000 = $0.016 monthly or $50 / 4,000 = $0.0125 annually. Sume is $0.20 / 1 minute = $0.20. That is a 12.5 to 16 times gap at full use of the allowance, which is why a team captioning thousands of minutes should not use per-job billing.

Equal spend is where it flips. At $50 a month you could caption 250 clips on Sume, which uses 250 of Kapwing's 4,000 credit-minutes. If you caption fewer than 250 one-minute clips a month and would use nothing else in Kapwing, the per-job route costs less; at 4,000 minutes it would cost $800.

What the per-job price includes

A Sume caption job is a render, not just a transcript. You choose a style (slam, punch, tiktok-green, korean-ad, or a Hangul identity), a font for Hangul styles, and optional design overrides for colors, typography, placement, phrasing and motion. Sending source_caption_id restyles a finished job without a second transcription, and the price stays $0.20 because a restyle is still a render.

You can also send script_text so the burned text matches your script, or cues for silent clips with no speech recognition. That work is billed the same $0.20.

Verdict

If you caption in bulk and a person uses the same subscription for editing, dubbing and subtitles, Kapwing Business at $50 to $64 is the better value. If captions are one step in a pipeline you run from code, a few hundred jobs a month at $0.20 each, with no subscription and a design you can change per request, is the better fit.
