Hi -
When would a person want to employ mpeg2enc's "-Q" option?
The usage() summary says:
--quantisation-reduction|-Q num
Max. quantisation reduction for highly active blocks
[0.0 .. 5] (default: 0.0)
I take this to mean that if '-q 6' is being used and '-Q 1.0' is
given then the encoder can, if need arise, raise '-q' to ~7. Correct?
This seems like it would be a good thing to do, giving the encoder
some leeway for active scenes.
Or does -Q do something else that might not be desireable all the
time?
Cheers,
Steven Schultz
