Video subtitle & watermark removal

POST /api-platform/v1/video/remove-subtitles detects subtitles when region is omitted, or processes the supplied rectangle. POST /api-platform/v1/video/remove-watermark requires one fixed rectangle. Coordinates are integer pixels in the original encoded video, with x2 > x1, y2 > y1, entirely inside the frame. Moving or multiple watermark regions are not supported in this release.

Parameter	Values
`videoUrl`	Public HTTP(S) video URL, at most 200 MiB / 600 seconds
`engine`	`base` (default), `pro`
`method`	BASE only: `inpaint` (default) or `blur`; omit for PRO
`region`	`{x1,y1,x2,y2}`, optional for subtitles, required for watermarks

Normalize video rotation before submitting. PRO requires an MP4 container and a shorter edge no larger than 1080 pixels. PRO availability depends on the server's upload configuration. Billing uses server-probed duration in 30-second blocks and the current API price. Tools API explains billing, idempotency, media uploads, and polling.

Create returns {taskId,status:"processing",type,model,statusUrl} inside data. Query GET /api-platform/v1/video/cleanup/tasks/{taskId}. A completed task returns status:"ready", videoUrl, progress, and usage:{credits,units,refunded}. A failed task returns status:"failed" and error:{code,message}; charged failures refund the original API transaction.
