Gekker 0 Posted February 7, 2018 Report Share Posted February 7, 2018 Hello, Before converting, click "Video Options", resize to a smaller video and select a lower number of "Frames Per Second". Link to post Share on other sites
billlee 0 Posted February 8, 2018 Author Report Share Posted February 8, 2018 Thank you very much Gekker! This makes a big difference of course. Reducing both frame rate and resolution by 50% reduced the GIF to 7 MB, only 10 times rather than 40 times larger than the original. And of course, quality is reduced. I was naively expecting too much of GIF. Wikipedia says: With the introduction of widespread support of the HTML5 <video> tag in most web browsers, some websites use a looped version of the video tag generated by JavaScript functions. This gives the appearance of a GIF, but with the size and speed advantages of compressed video. Notable examples are Gfycat and Imgur and their GIFV metaformat, which is really a video tag playing a looped MP4 or WebM compressed video. Thanks again! Link to post Share on other sites
