A value of 0 stands for "high compression is important" a value of 1 for "high image quality is important".
Changing this value affects the encoding of video frames which are subsequently written into the track. Frames which have already been written are not changed.
This value has no effect on videos encoded with lossless encoders such as the PNG format.
The default value is 0.97.
