MP4 VIDEO quality poor with HTML5 only Nov 16, 2017 By Brendan Leahy I have published a html5 only course (using SL360) which includes mp4 videos. Even with quality level pushed out to 9 when publishing, the video quality (screen recordings) are poor and blurry. I have published the exact same story using SL2 without HTML5 output included and videos are fine (when video quality is increased to 9). The problem appears to be video quality when published with HTML5 only. Any ideas why this is so?
