Easy to use! This site is my must go-to tool every time that I need to adjust my video speed. The interface is so intuitive; I just spent a little time learning how to use it the first time and I got it. It offers multiple choices to adjust my video, which is the best feature I like. Thank you.

I've been looking for such an online tool to make slow-motion video for a long time. Most online software advertise they are free to use. But in the end, you'll find they will ask you to pay for the processed videos. Otherwise, it will leave a big watermark in the center. This site has no such tricks.
