@ -468,6 +468,10 @@ form @var{num}:@var{den}, where @var{num} and @var{den} are the
|
||||
numerator and denominator of the aspect ratio. For example "4:3",
|

"16:9", "1.3333", and "1.7777" are valid argument values.
|

If used together with @option{-vcodec copy}, it will affect the aspect ratio

stored at container level, but not the aspect ratio stored in encoded

frames, if it exists.
