    Convert your WebM to ProRes

Like many of you lucky enough to purchase a PS5, I have been enjoying my time with the new console. One feature I started playing with is the video game capture feature via the "Create" button. I have been capturing my favorite clips here and there and selected the best ones to include a video I want to share. Unfortunately, I ran into trouble. None of my video editing applications (FCPX, DaVinci) support the WebM container. My favorite clips were all captured using WebM.
If you like me have all your favorite clips stuck in WebM then I have a solution for you. FFmpeg! This free software includes a ProRes encoder that simple enough to use works on Davinci Resolve (free version available) and Adobe Premiere! (FCPX of course supports ProRes.) See links below.
MacOS (and Linux)

On the MacOS, you can use the following command (Bash) to convert all WebM files in the current directory to ProRes.
