Adjusted, please check (was Re: [Esug-list] Test mp4-movies from ESUG, feedback wanted...)
Hi!
Ok, I have looked at responses from Andres, Martin etc and made the following adjustments to the script:
"The sound level is a little low": I added "-D 2.0", dynamic range compression that might help. Haven't listened myself :)
"It seems you can tell HandbrakeCLI to use CRF ": Yes, I moved to use that and have now a quality setting of 0.5.
Regarding aspects, I enabled anamorphic (not sure what it will do!): http://trac.handbrake.fr/wiki/AnamorphicGuide
------------------ I have now uploaded two different new versions of esug44.mp4 (using the above changes) that are less than HALF the size of esug44.mp4 to:
Details: esug44-2.mp4 built using:
HandBrakeCLI -i $1.$2 -o $1.mp4 --preset="Normal" -p -m -I -q 0.5 -e x264 -x ref=2:bframes=2:me=umh -E faac -B 32 -R 22.05 --mixdown mono -D 2.0 -d fast --denoise medium
esug44-3.mp4 built using:
HandBrakeCLI -i $1.$2 -o $1.mp4 --preset="Normal" -p -m -I -q 0.5 -e x264 -x ref=5:mixed-refs:bframes=4:bime:weightb:b-rdo:me=umh:subme=9:filter=0,-1:trellis=2:threads=4 -E faac -B 32 -R 22.05 --mixdown mono -D 2.0 -d fast --denoise medium
The difference lies only in the options to x264 and this last version rips all options from this webpage:

Now... time to pick! esug44-2 or esug44-3? You may not even be able to tell the difference :)
When decided I have 48Gb to churn through!

I can't speak for the audio quality as I haven't played them with sound on, but the video looks abit better in version 3 to me, with some more contrast. Compared still pictures at 1:06, in version 3 the blackboard feels easier to read, and items on the desk behind the speaker seem like they have more detail as well. To me, the hair looks less blurry too.
Cheers, Henry

Super! Then unless someone reports problems in playing version 3 or reports any other issues I should look at (not sure of the aspect ratio thing for example), I am set to go for that one.

Amazing discussion ... I was able to reduce a "little" video from 234 MByte (Pinnacle 12 - mp4) to around 95 MB using your tips.
Thanks !
