This type of layout displays a single big pane and several small panes. If the view focus has been
changed (for instance with left and right Far End Camera Control operations), then the big pane shows
the selected participant. If a conference participant has been set to "important" then its video stream is
shown in the big pane.

the selected participant. If a conference participant has been set to "important" then its video stream is
shown in the big pane.
However, if a participant has been set to "important" and the view is focused on a (different) specific
participant, the focused participant is shown in the big pane, and the "important" participant is shown
in one of the small panes.

If the view has been focused on a participant and the same participant is also set as "important" then
that participant is shown in the big pane.
that participant is shown in the big pane.
These layouts have two large panes and several smaller ones. If the view focus has been changed
(for instance with left and right Far End Camera Control operations), then the upper or left large pane
shows the focused participant. If a participant has been set to "important" then that video stream
appears in the lower or right large pane.

If the same participant is focused and "important", that video stream appears in the upper or left pane.
For these layouts, if the view has been focused on a particular participant, that participant appears in

In layouts with three large panes, even if the view is focused on a specific participant and another has
been set to "important", one large pane remains. This pane displays the "loudest" remaining
participant.

Clipped panes
The majority of the conference layouts defined by the MCU, for example:
have in common that all of their panes, whether big or small, have the same aspect ratio as the view
itself. That is, the panes' widths and heights are in the same proportion as the width and height of the
encompassing view.
itself. That is, the panes' widths and heights are in the same proportion as the width and height of the
encompassing view.
By comparison, there are some defined conference layouts, for example:
in which this aspect ratio preservation does not occur. In these cases, the MCU scales the participant
video stream according to the larger dimension of the pane.
video stream according to the larger dimension of the pane.
For example, in the layout to the left, the size of the top left pane is one half of the view width and two
thirds of the view height. Because two thirds is greater than one half, the MCU scales the participant
video stream to two thirds of its size and thus a small amount of the left and right of the original image
will not appear in the final composed layout.

Video stream vs. fixed bitmap images
For video conference participants, the image that displays in the layout view pane is either the live
video stream (if viewing from the video endpoint) or a captured video image from the current video
stream (if viewing from the web interface).
