Async Video Background Removal at $0.10/sec Launches
Video background removal just got faster—and cheaper. The new async endpoint from useKnockout processes video in the background, returning a job ID immediately and cutting what would be a 30-second sync wait down to a few API calls. At $0.10 per second with a 15-second cap, a 5-second clip runs $0.50, far below per-frame competitors.
Why async changes the game
Synchronous APIs hit a wall with video. Even a short 5-second clip at 30fps equals 150 frames; at 200ms per frame, that’s 30 seconds of blocking time. Async solves it. POST /video/remove uploads the file, returns a job ID instantly, and lets you poll for status via GET /jobs/{job_id}. When ready, the result is a ProRes 4444 file with full alpha—ready for Premiere, Final Cut, or DaVinci.
Pricing built for solo builders
Video is billed on a dedicated video.seconds meter, separate from image processing. A 7-second clip costs $0.70; anything over 15 seconds is trimmed automatically. That’s a fraction of per-frame pricing: remove.bg’s hypothetical video API would charge ~$15 for the same 5-second clip, while other services bill per frame at 30fps. For indie devs, the gap is stark.
One-person ship, rapid releases
useKnockout’s video endpoint is the latest in a month-long streak of releases, all self-hostable under an MIT license. Recent additions include collage creation, RealESRGAN upscaling, and studio-shot face restoration—each shipped by a single maintainer in days, not quarters.
Why it matters
For indie devs, background removal in video is either a budget nightmare or a feature skipped entirely. Async processing and transparent per-second billing remove both barriers. The real win isn’t just speed—it’s making high-end video editing viable without enterprise budgets.
