YouTube has added a slow motion (‘slomo’) feature to its Enhancements and YouTube editor tools. It allows you to add a smooth slow motion effect to your video, and it will look like it was filmed with a high speed camera.
The effects are surprisingly good, as you can see in the Times Square example video below. Even when video is slowed down to 1/8 speed, it still looks smooth. Open the YouTube editor, and drag one of your videos into a new project. Hover the mouse over the video and click on the magic wand to open the effects tool. Here you can add ‘slomo’ to your videos.
The YouTube editor is a really simple tool, which can really improve your uploaded videos if you spend a little time with it. As well as slow motion, you can alter the brightness and contrast, pan and zoom, stabilize and toggle Black and White mode. You can also add text, as well as audio really easily.
