MP4 to Text Online
Turn speech from an MP4 video into editable text with List55. The browser extracts the audio and discards the video images, then sends only the prepared audio through the normal transcription flow.
How to transcribe a MP4 file
- Open List55 and press the upload button.
- Choose the MP4 file that contains the speech.
- Wait while List55 prepares the audio and transcribes it.
- Review the editable text, then copy it into the app where you need it.
Audio extraction from MP4 video
MP4 is a media container and can hold different audio codecs. List55 uses the first readable audio track, converts it to MP3, and reports an error if the video has no supported audio or is protected.
If the file does not work
The file must contain a readable audio track. Incomplete, corrupt, encrypted, or DRM-protected media cannot be transcribed. List55 first uses its lightweight browser converter and loads FFmpeg only when broader format or codec support is needed.
