What is MediaFlow?

MediaFlow is a desktop media workflow app built for people who work with video files, audio tracks, subtitles and media containers.

Instead of switching between a converter, a subtitle extractor, a muxing tool, a transcription tool, an OCR tool, a file renamer and a metadata inspector, MediaFlow brings the common media tasks into one interface.

Use MediaFlow to:

extract subtitles from MKV, MP4 and other media containers;
extract audio, video or subtitle tracks as separate files;
add SRT, ASS, SSA, VTT or audio tracks to a video;
transcode video and audio files for playback, editing, sharing, archiving or smaller file size;
generate subtitles from audio or video speech;
recover burned-in subtitles from video frames with OCR;
translate subtitle files while keeping timing and structure;
batch rename or copy media files with preview;
inspect codecs, streams, tracks, duration, languages, bitrate and metadata.

MediaFlow is designed around reviewable workflows: you can check tracks, filenames, subtitles, translations, OCR output, transcode settings and exports before writing final files.
