I have been watching a fast-moving video that I'd really love to dissect in slow motion (half or quarter speed; frame-by-frame isn't necessary in this case). Is there a quick and easy way to accomplish this?
www.watchframebyframe.com supports half and quarter speed (frame-by-frame and precision timing as well!).
You don't really need to much. Just download the Chrome extension from EmbedPlus. You can learn more here:
