Questions about Video Explainer

How long are the videos?

Short. Each frame runs for a few seconds, so ask for “about 30 seconds” and it sizes the video to match, up to a maximum length.

Can I download the video?

Yes, as an MP4. It also stays in your documents, ready to reopen or download later.

Do I need a textbook for it?

No. Video Explainer works from your question alone, so you can use it for any idea.
