Here's what happened before this GIF. I added the zoom functionality and then dragged that 🔍 to the point on my video that I wanted to zoom-in on. No, the final video won't have that magnifying glass, it's just for you to remember while editing.
Notice that I can drag how long I want the video to zoom in for (max of 10 seconds), and how much I want to zoom in.
The next option on the left sidebar (Effect) is similar, but instead of zooming in, it lets you select a portion of your screen that you want to highlight for x seconds (which is just another way of saying it will blur everything other than your selected portion).
I could explain every feature but you get the gist; you can add transitions, text, intros, and so on. And at the end of the day, you can download this video (without a watermark) for free.
So there you have it! A free-to-use online video editing website that lets you upload videos, use features such as text, transitions, or zooms, and download without having to create an account.
