service / x402-video-subtitle-mux-c94bbcba
Video Subtitle Mux API
Takes a video (up to 24 MB) and one to five SRT or WebVTT subtitle texts with language codes, and returns the video with each as a separate, switchable subtitle track tagged with its language, the first marked default. Picture and sound are copied, not re-encoded, so quality is unchanged and it is fast. MP4 uses mov_text (plays in QuickTime, browsers with players, most phones); MKV uses SRT tracks (VLC, mpv, Plex). Unlike /v1/burn-subtitles nothing is drawn into the picture.
