Extract WebM video and audio from youtube and save them

How can I convert a youtube video to WebM video and audio and save it

1. Type or paste the YouTube url in the search box.

2. Click the “start” button

3 You can select the WebM video and audio file format and the quality you want in the tabs

4. Save the downloaded file to your computer, memory card, or phone.

5. If the file isn’t downloaded and the video has started to play, click on the three dots on the video-player and click ‘Download’.

Oh, my God. I don't see WebM video and audio file format in available formats for download

Due to youtube limitations or technical issues with the site, not all formats (e.g. WebM video and audio format) files are present. If this happens to you, you're in luck, try buying a lottery ticket (Hee-hee).

Official recommendation: please save the video in one of the other audio or video formats suggested. Then play it directly with an audio player or use a third-party tool to convert it to WebM video and audio.
