Dropping frames due to too big video input while being 1920x1080 input and stream #136

When I try recording Rainbow Six Siege in borderless fullscreen using screen-capture-recorder + ffmpeg, I get these errors [dshow @ 00000297d9d3d600] real-time buffer [screen-capture-recorder] [video input] too full or near too full (545% of size: 3041280 [rtbufsize parameter])! frame dropped! Last message repeated 69 times.

Encoding can't keep up you could try a different codec x264 ultrafast comes to mind...

Tried ffmpeg -f dshow -i video="screen-capture-recorder" -r 30 -c:v libx264 -preset ultrafast test.mp4 but get the exact same error.

Should work, here's some more examples, it's the best I can provide, thanks! https://trac.ffmpeg.org/wiki/Encode/H.264

Try setting rtbufsize for video in ffmpeg command parameters should resolve this. e.g.

ffmpeg.exe -rtbufsize 1500M -f dshow -framerate 30 -i video="screen-capture-recorder":audio="Microphone (Realtek Audio)" -c:v libx264 -r 30 -preset ultrafast -tune zerolatency -crf 28 -pix_fmt yuv420p "test.mp4"

Of course this means your system should have enough RAM for ffmpeg to use as video buffer. Above works well for 4K recording @15fps. You can also play around with changing to lower framerates.
