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.
