Ever since we saw the matrix, we as a society decided that slow-motion videos as a whole are something we need to be able to do at the drop of a hat. This trend has carried over to our mobile device platforms, Microsoft includes support for slow-motion video in the Windows 10 Camera app, so phones with capable cameras like the Lumia 950/950 XL can already capture slow motion videos out of the box. Other manufacturers and software makers like Apple and Google also have camera apps which are capable of slow-motion video capture.
But what if you need to convert that video you captured of your good friend Billy skateboarding because you think it would look really, really good as a slow-mo video for Instagram. Or you just managed to capture a video of a butterfly unfurling its wings in the rain, and a slow-motion video of that to share to social media is just what you need to upgrade your personal #brand. Microsoft’s built-in Photos app for Windows lets you convert videos to slow-motion after the fact. It’s not as elegant as a full-featured dedicated video editing app, but it’ll do for quick and dirty edits.
