I am recording a 4K display but I only need the output to be in 1080p is there a way to make the output directly into 1080p without having to transcode the output from wl-screenrec as a post-processing operation?
Update: With the variable frame-rate I think I will not need this feature after all. The output files even though they are in 4K are comparable in size to the 1080p downscaled video. It could perhaps be a good thing to have anyway to make it explicit to newbies like me that are not familiar with ffmpeg workflows.
