Fixed Capture Area

Define a precise area in the source properties to always capture the same part of the screen. The top and bottom of the window will remain hidden.

Window Capture

Use Window Capture mode to record a single application for example, educational software without showing the rest of the desktop. This avoids distracting elements.

Adjusting the Scene

Each source is placed in an OBS scene. Resize and reposition it so that it fits perfectly into the final video.

In short: Fixed crop or target a window to control the display, then adjust the source within the scene.
