Parent comment specifically mentions recording for game development so 1080p at 10fps probably isn't going to cut it.

Update it to be 20~25 fps then, still won't take ridiculous amount of space.

Unlike movies, the content on screen recordings usually remains roughly the same for minutes before switching scene. So it can achieve significantly higher compression ratio even at high fps

But the TLDR, ffmpeg can remove duplicate frames:

    ffmpeg -i in.mkv -map 0:v -vf mpdecimate,setpts=N/FRAME_RATE/TB out.mp4
