Notes...........: We have been doing quite a few proper, its
                  sad, we dont like doing it, but it has to be 
                  done to improve quality. We are aware that we
                  are contradicting the rules we signed with this
                  but read and you will know why. 

                  (low bitrate but you CANT judge quality soley on bitrate
                  anyone with a little encode experince will tell you this).
                  
                  To CDDHD:
                  ----------------------------------------------------
                  We have been enduring your settings quite too long, cddhd.

                  First of all 8x8dct=0 WHY? Dont give us the crap
                  about standalone compabiliy. The players arent out yet. We
                  dont know what they will support. If you are so worried about
                  compablity, go for WMWHD, and rape quality. 
 
                  And your keyframe settings are insane. Min=1 and Max = 150?
                  Are you high? keyint min = 1, do you need a I-frame for every frame? WHEN? 
                  Do you think it will help jumping in the movie? 
 
                  Ever noticed problems with jumping in another rip? Its max 250 (~10sec)
                  and min 25 by default. Those settings are fine. I-frames take alot 
                  more space and you cant work the algorithm magic on them. So there is a
                  reason to try and keep them as few as possible.
 
                  (But kudos you guys have used way worse on other rips).

                  Motion Estimation Method: DIAMOND. 
                  To quote 
                  http://www.digital-digest.com/articles/x264_options_page6.html
                  "Only use when maximum encoding speed is required." 
                  This should NEVER ever be used.

                  Rate Distortion Optimization
                  brdo=0, wtf? you are using b-frames right? yeah you are (had to check).
                  Another rape on quality for no reason except faster encode.
    
                  mixed_ref=0, anyone supprised?

                  When using 8x8dct=0 + me=dia + brdo=. You have broken the rules you signed
                  yourselves, good work. All these have been changed from better default 
                  values, to these faster values. So its done on purpose to win 
                  races and rape our quality.
 
                  Comparision screenshots are avabile in /screens if you dont trust us.

                  And as an extra bonus CDDHD rip is slightly overcropped.

                  The only reason their encode looks as good as ours is that they have
                  DOUBLE bitrate and still not better than ours!
 

                  To Scene:
                  -----------------------------------------------------
                  But its a sad thing limiting yourself to dvd5 and dvd9 usually ends you up with 
                  either too low or too high bitrate. What people need to understand is that there is 
                  a bitrate were you wont achive higher quality. So if a 6GB rip looks as good as 
                  a full dvd9 in every way. Why waste credits, hdd, space etc etc on nothing?

                  This rip is made with constant quant set to 20. Of course you cant just blindly 
                  trust that, so take a look in compare dir. And see if the oversized dvd9 looks any
                  better? The rules need to be changed.

                  All movies are unique and you can easily tell how people choose between dvd5 and 
                  dvd9 that all of the sudden a rip dosnt need 3gb more bitrate. We to allow rips
                  to be 3, 6, 7gb or whatever if that the pivot where no quality is achieved. Everything
                  else is just a waste. 
 
                  The method can of course be discussed but the situation as it is now is unbearable.
 
                  And septic, turn on 8x8 transform too!
 
                  Encoder commandline we used for this: 
                  --qp 20 --ref 5 --mixed-refs --no-fast-pskip --bframes 3 --b-pyramid --b-rdo --bime 
                  --weightb --filter -2,-2 --subme 7 --analyse all  --8x8dct --threads 2 --thread-input --progress --output 
                  "faceoff.mkv" "faceoff.avs" --me umh 

                  Trellis is useless on constant quant.
