Overview
This gives a suggestion for the [quality](#//api/name/quality) of the encoding as an
integer value. The intention of the [quality](#//api/name/quality) attribute for
video is to specify a non-default trade-off between frame-rate
and still-image [quality](#//api/name/quality). For video, the value is in the range
0 to 10, with the following suggested meaning:
10 - the best still-image [quality](#//api/name/quality) the compression scheme can
give.
5 - the default behaviour given no [quality](#//api/name/quality) suggestion.
0 - the worst still-image [quality](#//api/name/quality) the codec designer thinks
is still usable.
It is a media-level attribute, and it is not dependent on
charset.
