Video Watermark API
Takes a video of up to 5 minutes and returns it with a text watermark rendered into the picture in DejaVu Sans, at top-left, top-right, bottom-left, bottom-right or centre, with selectable size relative to the picture height and opacity, optionally followed by a running timecode — useful for review copies and drafts. Sound is copied unchanged. Output MP4 (H.264/AAC) inline as base64, max 24 MB. Runs locally with ffmpeg. Billing per started video minute.
