I'm the developer of the Video Screenshot chrome extension. It allows you to capture full res screenshots of video from YouTube, Netflix, Vimeo, Amazon Prime, Hulu, and the rest of the internet, without player controls or watermarks.
In order to keep the extension free for everyone, I've created a Buy Me a Coffee page for donations in hopes to help cover the costs of maintenance and development of new features.
I spend more time on upkeep than you might imagine, the majority of it goes into maintaining the code to keep the extension working across dozens of sites for 10,000 users around the world.
If you can chip in a couple bucks to help keep it free, please do so! If this donation platform proves successful, I can dedicate more time to adding new features—most notably adding subtitles (by far the most requested feature) to as many websites as possible. Thanks!
