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

I wrote more about it here: https://news.ycombinator.com/item?id=32223240

But the TLDR, ffmpeg can remove duplicate frames:

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

1080p may easily mean that the code is unreadable if you have a decent size screen.
