How-to
How do I upload a video lesson? (and cloud import)
In short
Open a Video chapter, click Add Video File and choose a file from your device, or from a connected cloud drive.

Open your course, go to the Curriculum tab and open a Video chapter.
Click Add Video File.
In the Add a video window, choose My device.
Pick the video file. The chapter shows a progress bar while it uploads.
Wait for Processing your video. You can leave the page; it finishes by itself.
When it says Video ready, the chapter is done.
Good to know
The chapter shows the file types you can add and the size limit per video for your plan.
Google Drive, OneDrive and Dropbox appear in the same window. They are greyed out until your platform administrator connects them.
To replace a video, click Delete video and add a new one.
