I am looking to record my desktop in high quality (not nearly as lossy as H.264). I have tried OBS @ 200mbps and nVidia Shadowplay @ 50mbps and the text on my desktop is still noticibly blurry when i view the video I just recorded at the native resolution it was recorded at. OBS is a little bit better than nVidia.

Try lossless encoding with ffmpeg

First, with YUV444P

ffmpeg -f gdigrab -framerate 60 -i desktop -crf 0 -pix_fmt yuv444p -preset ultrafast yuv-cap.mp4

If not clear enough,

ffmpeg -f gdigrab -framerate 60 -i desktop -c:v libx264rgb -crf 0 -pix_fmt bgra -preset ultrafast rgb-cap.mp4

These will likely not be compatible with most video editors, but if the result is satisfactory, then you can transcode at leisure to a compatible codec like PNG in MOV..etc

You can add -draw_mouse 0 before -i desktop to skip recording the cursor.

  • How would I get this up to 60fps? – muncherelli Feb 18 '16 at 14:45

  • Thank you. Is there a way to only capture one monitor? (i have two 1080p side-by side) – muncherelli Feb 18 '16 at 15:00
  • Yeah, two ways. Switch off one of them :) --or-- add -offset_x 1920 -offset_y 0 -video_size 1920x1080 before -i desktop if you want to capture the 2nd monitor which is the right half of your desktop. – Gyan Feb 18 '16 at 15:10
  • I've had a little time to test this out finally. gdigrab seems to be fairly horrible at capturing high framerate desktop recording. – muncherelli Feb 25 '16 at 22:10
