FFMPEG Command to Record Desktop Screen or Capture Video and Save as MP4 File in Windows 10 Full Tutorial For Beginners




Use DirectShow

Use a DirectShow device:

ffmpeg -f dshow -i video="screen-capture-recorder" output.mkv

This will grab the image from entire desktop. You can refer to a list of alternative devices.

If you need audio too:

ffmpeg -f dshow -i video="UScreenCapture":audio="Microphone" output.mkv

If you want to capture the audio that is playing from your speakers you may also need to configure so-called “Stereo Mix” device.


ffmpeg -f dshow -i video="UScreenCapture" -f dshow -i audio="Microphone" output.mkv

You can list your devices with:

ffmpeg -list_devices true -f dshow -i dummy

Use built-in GDI screengrabber

You can also use gdigrab as input device to grab video from the Windows screen.

To capture all your displays as one big contiguous display:

ffmpeg -f gdigrab -framerate 30 -i desktop output.mkv

If you want to limit to a region, and show the area being grabbed:

ffmpeg -f gdigrab -framerate 30 -offset_x 10 -offset_y 20 -video_size 640x480 -show_region 1 -i desktop output.mkv

To grab the contents of the window named “Calculator”:

ffmpeg -f gdigrab -framerate 30 -i title=Calculator output.mkv

Hardware Encoding

You can use hardware acceleartion to speed up encoding and reduce the load on your CPU. For example, with NVIDIA hardware encoding:

ffmpeg -f gdigrab -framerate 30 -i desktop -c:v h264_nvenc -qp 0 output.mkv

Lossless Recording

If your CPU is not fast enough, the encoding process might take too long. To speed up the encoding process, you can use lossless encoding and disable advanced encoder options, e.g.:

ffmpeg -video_size 1920x1080 -framerate 30 -f x11grab -i :0.0 -c:v libx264rgb -crf 0 -preset ultrafast output.mkv
