"x264:dxva hd extra quality" is giving me poor quality resolution

Please tell me the profile in Megui to use that preserves the resolution definition of the sd dvd being encoded.

I beleave Megui x264 profiles doesn't change the resolution...

I'm getting a lot of macroblocking after encoding.

here is my avisynth script I am using with the profile:

Code:

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\DGDecode.dll")
setmtmode(5)
mpeg2Source("C:\Users\Red\Desktop\test run.d2v") 
setmtmode(2)
a= last
b=a.Spresso()
SeeSaw(a,b)
LimitedSharpenFaster(strength=11)
LimitedSharpenFaster(strength=11)
super = MSuper(pel=2,hpad=4,vpad=4)
backward_vec = MAnalyse(super,chroma=false, blksize=16, isb = true, search=5, searchparam=1)
forward_vec = MAnalyse(super, chroma=false, blksize=16)
MFlowFps(super, backward_vec, forward_vec, num=0, mask=1, ml=49)
changefps(60)
distributor()
Crop(0,56,-0,-62)
Spline36Resize(1280,544).AddBorders(0,88,0,88)

And what bitrate or quality you choose for this source?

By the way this script is not SD DVD, but HD

I know, I'm upscaling it from sd dvd.

From the Megui input tab I click Avisynth script and open the script I posted.
Then I click Video Output and where to save the file.
Then I click Encoder settings and choose profile: "x264:dxva hd extra quality".
Then I click Enqueue and from the Queue tab I click Start.

From the Encoder settings I can click "Config", and then Lossless Bitrate.
I'm wondering if this would help as this Config tab was left at default before.

Lossless bitrate? What is this? If you choose lossless option then you should not see any difference in quality between source script and final encode regardless of other settings.

After you alter settings in config dialog, you should press OK, then Yes or No (but not Cancel) and then Enqueue.

Thank you for your help.
