"Glimmerglass prepares an animation you already made for the web with transparency, in the two video formats browsers use: HEVC with alpha for Safari and iPhone, and VP9 with alpha for Chrome, Edge and Firefox. The wrong one can play on a black box or with grey edges. Ask why your transparent animation is not working to get an explanation. Bring your own animated WebP, GIF, APNG, MOV, MP4 or WebM with transparency, and Glimmerglass converts it into one .glim file with several sizes, plays it in the chat over the background you choose, and hands you the file, its poster and the code to paste. Play always, on hover or in view, speed, looping, fit and more are saved in the file. You can try the sample animations right away. Converting your own files needs signing in with an existing Glimmerglass license. Glimmerglass does not create animation or remove backgrounds."
