 This App is a GTK frontend to AMD's FidelityFX Super Resolution codebase, which allows you to upscale basically anything that is some kind of an image. 
 - Choose a file to upscale (intending to support at least .png, .jpg, .mp4 and .mkv, but future versions may include support for other formats as well
 - Output file will be written to a specified folder.
+- App will split videos into single-frame image files so FSR can upscale it and then reassemble the whole video and add the audio to it again. This means no vrr is supported!
