You can solve this by splitting frames up with convert(1) and set each of +them as background with an interval of ~0.01 seconds. A better approach would +be to use mpv with the --wid=0 parameter which is less CPU intensive. You can achieve more extreme results by using scrapthumb in conjunction with semi-automatic customization tools. Have a look at
