This dialog contains edit fields for additional video capture settings.
The method for resizing the main window can be selected:
The size of the preview/overlay display is linked to the input's size (when
resizing the main window, the display keeps its size)
The display's size can be linked to the main window's size (when resizing the
main window, the display follows suit ignoring the input's size) which results
in scaled previewing / overlaying.
To keep the video file from growing arbitrarily large, the maximum number of
frames to store in the file is set here.
The last two settings enable audio capturing, and enable the synchronization
between the audio and video capture data.
