@ -4906,6 +4906,8 @@ Description
* ``"auto"``: Automatically assign a fitting frame rate
based on delays between frames.
* ``"uniform"``: Like ``auto``, but assign an explicit frame rate
only to Ugoira with uniform frame delays.
* any other ``string``: Use this value as argument for ``-r``.
* ``null`` or an empty ``string``: Don't set an explicit frame rate.
