How to Record Gameplay on PC on Steam for Windows 11?

Most people know FF mpeg only for converting files. The fact that it has a native Windows screen capture filter called ddagrab is buried in documentation and rarely discussed outside developer circles. It uses the Desktop Duplication API (DXGI), the same underlying technology Windows itself uses for screen capture, introduced in Windows 8 . This means it taps directly into the GPU's output pipeline with minimal overhead—significantly faster than the older gdigrab method.

There's no graphical interface. You must construct a full command line yourself, specifying hardware device initialization, filter parameters, encoder choice, and output format. A basic command looks like this:

text
ff mpeg -init_hw_device d3d11va -filter_complex ddagrab=0 -c:v h264_nvenc -cq:v 20 output.mkv

This captures your entire desktop using hardware encoding, but the command structure is unforgiving—one wrong flag and it fails. For how to record gameplay on PC on Steam, you'd need to manually configure resolution, frame rate, and quality settings through options like video_size, framerate, and cq .

If you want a completely free, native, no-third-party method to how to record gameplay on PC on Steam, ddagrab delivers on that promise for video. But the learning curve is steep, the documentation is developer-oriented, and you'll be on your own for audio.
