HOW IT WORKS

Three steps and you're done

From opening the file to subtitles syncing up, playback starts instantly with no setup.

01

Open a video

Click or drag a file into the window and playback starts immediately.

02

Load subtitles

Load a .srt or .vtt subtitle file and it syncs to the playback position in real time.

03

Play & auto-convert

If the codec isn't supported, it automatically attempts re-encoding and resumes playback.
