Screen Capture - Single Window​

It is possible to capture a single window instead of the entire screen. The content of the window is captured even if the window is partially or completely in the background. You need to enter the Window handle or Window class name into the field.

At the moment there are two modes for capturing a single window:

  • Auto Size: adjusts the output size depending on the size of the window to capture, before the directshow graph is started

    Auto Size

  • Fullscreen: the output size is equivalent to the screen size, the window size is not scaled, the window can be resized while the graph is running and one can see the whole window at all times

    Fullscreen

  • Scaling example: if you need to downscale a full screen capture, use the additional "Resize/Scale" functionality in the encoder or add a resizer/scaler filter to the DirectShow filter graph

Region Capture​

If the output of the region area seems to be different from the specified region, check if Windows display zoom is enabled:
