Library and exercise videos share 25 decimal GB by default, adjustable by an admin. Reserves source, bounded output and thumbnail space. Both use the same technical processing ceiling of 2 GiB per source, with no separate exercise-video limit. PUT each file slice to its signed URL with exactly the specified length, then complete. The worker compresses the video and generates a thumbnail; save only the ready result URL. Upload rights expire after one hour. Do not expose signed URLs in logs. Requires the workout_library:write scope. This operation maps to /app/v1/workout/video-library/presign and retains its Workout V2 permission, feature-flag, and resource-scope checks. The clientId path parameter is resolved inside the company bound to the Public API token when present. ## OpenAPI ````yaml /openapi/public-v1.json post /public/v1/workout/video-library/presign openapi: 3.1.0 info: title: FITsociety Public API v1 version: 1.0.0 description: >- Developer Public API endpoints under `/public/v1`.
