Video Transcription & Subtitles

Turn a recording into a transcript and subtitles: play them on the video, correct them, and save them as SRT or VTT

How to use Video Transcription & Subtitles

  1. 1Add a recordingUpload an audio or video file, or start from a ready-made recording.
  2. 2Choose the languageSay which language is spoken, or let it be found. For a conversation, turn on speaker detection.
  3. 3TranscribeThe Finnish HH Whisper server transcribes it and times every segment, and every word.
  4. 4Make the subtitles rightPlay the video with its subtitles, choose how long they are, correct them, and save SRT or VTT.
  • Subtitles are made from the timed segments, and their length can be changed afterwards without transcribing again. Corrections are kept in the files you save.
  • Nothing is saved: the recording and its subtitles stay in this session.

Start from a ready-made recording

1. The recording
An audio or video file: MP3, WAV, M4A, MP4, WEBM, OGG, FLAC or MOV, up to 50 MB.
2. How to transcribe
The language, and whether to tell the speakers apart.

The language is recognised from the speech. A good choice when it varies or is not known.

Tells who speaks when, so that each subtitle can name its speaker.

Add a recording first.
