Video Processing

Scales the picture to a target resolution or scale factor, with optional letterboxing.

Crops to a rectangle in pixels or relative coordinates to remove borders or focus a region.

Rotates the frame by 90°, 180°, or 270° for portrait fixes or upside-down footage.

Keeps only the segment between start and end times for highlights or clips.

Demuxes the soundtrack into a standalone MP3, M4A, or WAV file.

Muxes new audio over the video; multiple inputs concatenate, with loop or pad for short tracks.

Joins clips in order into one timeline (typically re-encoded for compatibility).

Removes every audio track while copying the video stream when the container allows.

Captures one frame at a timestamp as PNG or JPEG for thumbnails or QA.

Applies a speed factor to both video and audio (e.g. slow motion or timelapse).

Burns SRT, VTT, or ASS subtitles into the picture for players without subtitle support.

Overlays a PNG, JPEG, or WebP logo with position and opacity for branding.
