Choose a video or screen recording containing audible Morse. File extension alone does not guarantee that its audio codec is supported.
Decode Morse in a video or screen recording. Select a scene, read its audio track, and replay it beside the text. This tool reads sound, not flashing lights.
Tab audio capture is unavailable here. Choose a screen recording file, or use the microphone near your speakers.

Choose a video or screen recording containing audible Morse. File extension alone does not guarantee that its audio codec is supported.
Use the waveform and start/end times to isolate the beeps. Keep complete characters and avoid unrelated dialogue where possible.
Review the selected range with the video and compare the text with the audio. Correct uncertain letters before copying the result.
This page analyzes sound extracted from the video. It does not measure flashes, blinking lamps or changing subtitles in the picture. For printed dots and dashes in a frame, save a clear still image and use the image translator. A silent flashing-light clip cannot be decoded by the audio tool.
Check that the file actually contains an audible track and that the beeps are present in the selected interval. MP4 and MOV are containers; the enclosed codec still has to be readable by the browser. If needed, export the audio as PCM WAV with a local editor and use the audio decoder. Renaming the extension does not convert a codec.
Full clip → scene with beeps → complete Morse passageIf the signal occurs only in one scene, enter start and end times around that scene rather than decoding unrelated speech. Replay the selected passage with its visual context, but accept letters only when the sound supports them.
Read printed Morse from a saved video frame →There is no YouTube downloader. Use a local recording you are entitled to process, or capture a playing browser tab with audio when your browser supports it.
Availability depends on the browser and device. If a capture prompt offers audio sharing, enable it. Otherwise use a local video or audio file.
No. Video decoding here means decoding its audio track. A flashing lamp without Morse sound needs a visual timing workflow that this tool does not provide.
