Video
=====

The :ref:`ATEM Mini` is used for handling all video signals.

Input sources
-------------

There are 4 external and 2 internal input sources:

- External
    - Camera 1
    - Camera 2
    - Camera 3
    - Screen
- Internal
    - :ref:`Media` player (aka ``STILL``)
    - Black

Preview & program
-----------------

The :ref:`ATEM Mini` differs between the preview and program (live) output.
Here are the important bits:

- Preview (aka ``PVW``) output is always **green**
- Program (aka ``PGM``) is output is always **red**
- Pressing an input source button will switch the preview to the selected source

HDMI out
--------

On ``HDMI out``, respectively the connected monitor, the output can be changed via buttons on the :ref:`ATEM Mini` to:

- External inputs (Camera 1-3 & Screen)
- Multiview (aka ``M/V``)
- Program output (aka ``PGM``)

Transitions
-----------

Preview (``PVW``) and program (``PGM``) can be switched by using one of the following buttons on the :ref:`ATEM Mini`:

- ``CUT``: Instant cut / switch
- ``AUTO``: Visual transition

Transitions can be changed via buttons on the :ref:`ATEM Mini` as well:

- There are 6 preconfigured transitions types
- Each transition type can have its own rate (i.e. ``0.5``, ``1``, ``1.5`` or ``2`` seconds)

Keyers 
------

PIP
~~~

To display picture in picture or overlays (lower thirds), use the :ref:`Stream Deck`:

- Select which PIP source you want (Camera 1-3, screen or media)
- Activate ``PIP Transition`` to toggle PIP with the next transition
- Press ``PIP On Air`` to instantly toggle PIP on program

Overlay
~~~~~~~

To display an overlay (e.g. speaker name) on the program, press ``Key {Media}`` on the :ref:`Stream Deck`:

.. note::

    The overlay can't be displayed in preview and is only available on program, so you might want to test that in advance.

.. important::

    If you manually tinkered with the downstream or upstream keyer and you no longer get the expected output, press the ``Reset keyers`` button on the :ref:`Stream Deck`.

Media selection
---------------

There's only one :ref:`Media` player available on the :ref:`ATEM Mini`, which means you can only display / use one :ref:`Media` at a time.
To select a new :ref:`Media`, press the ``Select media`` button on the :ref:`Stream Deck`.

.. note::

    This media is used for the ``STILL`` and also the `Overlay`_ downstream keyer.
