Awesome that you did this, and I trust it's true, but in the future, definitely refresh the screen as part of the cap.
PSA: YouTube Download Made Easy
Anytime you're watching a YouTube video you want to save, just add "pp" after "youtube" in the URL and download it.
example:
this youtube URL
https://www.youtube.com/watch?v=7VSR4_tAYvw
would become:
https://www.youtubepp.com/watch?v=7VSR4_tAYvw
Then you just choose the resolution you want to download.
