Media Metadata Editor
Reads and edits container metadata — title, artist, album art, codecs, duration and streams.
Burn Subtitles
Renders an SRT, VTT, ASS or SMI file permanently into the video frames with size, position, colour and outline control, drawn with the browser’s own fonts so Korean needs nothing extra.
Video Compressor
Re-encodes to a target file size or a quality preset, stepping the resolution down when the bitrate would starve it, and shows the projected size before it starts and the actual size after.
