Questions

Can I make a video from my own notes or worksheet?

Yes. Attach a PDF or photos of up to 30 pages and the video follows your material instead of a generic version of the topic.

How long are the videos?

A single topic comes out at one to three minutes. Broader topics are planned into chapters for a longer video, and you see the estimate before it renders.

Can students watch without an account?

Yes. Turn on the public link and anyone with it can watch in the browser. You can also download the mp4.
