today's Practical Ed Tech Live episode was, "is there a way that I can just take the audio out of the videos to publish it as a podcast?" There are a few ways that you can extract the audio from a video. One of the easier ways to do that is found in GarageBand. In the following video I demonstrate how to extract the audio from a video file that you have stored on your computer.
As I mentioned at the end of the video, you should only do this with videos that you created or videos that you have received permission to edit.
If you're looking for an easy way to publish a podcast, take a look at using Anchor.fm. Anchor makes it easy to publish your MP3 recordings as podcast episodes that get distributed through all of the major podcast platforms.
