The Seriously.js library seems pretty cool. I used to be a big movie gu (until college) and I was always amazed about how they do the effects of. I knew there was something called an editing bay where the producers and editors would lock themselves up for months to edit a hours of footage and condense it to 1 to 3 hours. They probably use some really expensive and high tech software to edit these videos which I don’t know have any experience in. But I have experience in coding and this library allows you to add effects to live or prerecorded videos through code.
