With dslrBooth and the Canon M50 you can create slow motion videos.
In dslrBooth, use the video option (Settings -> General -> Booth Mode).
Set the Canon M50 dial to video. Then go to Menu and select Video Recording Quality. Enable High Frame Rate, 120fps. This will record the video in slow motion which will then appear in dslrBooth as a slow motion video.
Please note this is only available with the Canon M50 due to the slow motion feature it has.
