From http://ffmpeg.org/ffmpeg-utils.html#Video-size

Specify the size of the sourced video, it may be a string of the form
widthxheight, or the name of a size abbreviation.

The following abbreviations are recognized:

...
‘qcif’

    176x144
‘cif’

    352x288
‘4cif’

    704x576

...and the list goes on.
