Add video from YouTube, Vimeo, or Loom, or upload a video file directly to a lesson. ## Add a video 1. Open **Courses** and select a course. 2. Open the lesson you want to edit. 3. Type `/` and choose **Video**. 4. Choose one option: * Paste a YouTube, Vimeo, or Loom link. Loom's **Copy link** URL works as is. * Upload an MP4, WebM, or Ogg video file. 5. Wait for the upload to finish, then save the lesson. Uploaded videos can be up to 1 GB. Keep the editor open while the progress indicator is visible. If an upload is interrupted, use the retry option; only the failed parts are re-sent. ## Replace or remove a video Select the video block to open its settings. Under **Replace video**, paste a new link or upload a new file, or remove the block from the lesson. Save the lesson after the change. ## Make it available to students A saved lesson can still be a draft. Publish the lesson when it is ready, and confirm that its course is also published. Lessons that contain a video show a video icon in the course outline and the lesson sidebar, so students can spot them. ## Troubleshooting * **The file is rejected:** Use MP4, WebM, or Ogg and keep it at or below 1 GB. * **The upload stops:** Check your connection, keep the tab open, and retry. * **Students cannot play it:** Confirm the lesson and course are published, then check the student's course access. * **A pasted link does not load:** Use the public YouTube, Vimeo, or Loom video URL rather than an editing or studio URL. Learn how to add and arrange every lesson block. Let students listen to a lesson instead, in a catalog voice or your own.
