Hello
I've posted a couple of times before, where it's for this reason or that
reason, now my problem is that since q-scale was set to -g 2 the
resolution has dropped drastically on the output.
the interesting thing is that the speed out is the same as 720p, however
on youtube it is good at a quarter of the resolution shown..
what should i adjust to make it good?
I have set the -g switch in vain, but it hasn't changed.
only the -presets switch made a difference.
But it's interesting that when youtube complained about the bad starting
frame, the picture was perfect, now it doesn't complain and the picture
is terrible
I am looking forward to your ideas, thanks in advance!
Robert
