Normally I use ‘medium', or now ‘slow' because I’ve got my NAS set
up with ffmpeg and just let it crank there in its own sweet time.
I started with testing a range of bitrates at medium 2-pass from a
bluray source. At least looking at the pngs, I found I couldn’t
really see any clear improvement above 2 Mb/sec, so I chose 3. I
can’t distinguish it from the source (except for the light/dark
business in some cases). Do you think the ‘png test’ doesn’t give a
good comparison?
Fair enough. I can see that 3M was enough with default for the sample
you posted, but not much happens in that.
I was just thinking that 3M + superfast could be a bit low for high
action scenes with flying cameras etc. As you are not using superfast
anyway that concern does not apply.
