Yes, you can use a YouTube video as a card.
Here is how:
1. On the Card List page, click “Add to section” and then “Create a new card” to have the “Create a new card” window pop up. Select “Study” and you will be directed to the Study Card Edit page. On the Study Card Edit page, click “YouTube” of the “Card body” section.
2. Go to the YouTube website (https://www.youtube.com ), and take note (such as by copying) of the YouTube video you wish to insert in the “YouTube Video URL” section of the YouTube Video pop up window.
3. In the YouTube Video pop up window, insert the URL of the designated YouTube video in the “YouTube Video URL” section and select “OK”.
[Note] Make sure that you take note of the URL of the YouTube video shown in the address field of the browser. The URL you can obtain from the “Share” function of the YouTube website does not work.
