By “playing in a browser” I mean when I play the video from the client’s staging website, or I drag the video straight from my Finder (Mac) into a browser (Safari in my case). I thought it must be the player compression as well, but it looks fine on mobile and in full-screen mode, and other videos I’ve compressed and posted the same way look OK. Weird.
Thanks for the quick reply, Vince. I’ll tinker with those settings.
