As usual, maximise the playback window and up the resolution, though note that 4K video is very bandwidth intensive, don't try streaming it unless you know that your connection is up to it! Plus the chances are that your video screen isn't anywhere near 4K resolution in the first place - if in doubt, stick to 1080p, which is perhaps more manageable!
Still impressive that this exists in 4K though, and that it was created on a phone (with help on the desktop to stitch the photos together, of course):
