50 fps in ProCoder 3

[byme]

I usually use Complementparity with MCBob to maintain 50 fps

codifying with Megui there are not problems, while with ProCoder 3 the image is blurred, moreover not maintain 50 fps

you know why?

[byme]

I prefer ProCoder to x264 because the image is more brilliant

there is a way to get the same brilliance with x264?


MeGUI x264

ProCoder 3 H.264

With x264 no, x264 encode the same colors than source, but with tweat in avisynth you could probalby get the same results, and encode this result with x264

[byme]

I do not know well the tweat function

you could do me a script? :thanks:



P.S. the colors than source are more similar to those obtained with ProCoder

[wyti]

It's hard to make a script without have the source, but the problem may come from the Yv12 conversion, read the avisynth doc, and try different number for the tweak function, you will find what looks good to you.

[byme]

you were right ... the source is more similar to coded with MeGUI by the capture of one frame... but differs in player
x264 probably in the player reacts otherwise

You can try
Tweak(Source,Hue=-0.1,bright=-0.2)
but due to yv12 limitation, it's not possible to get the same image than the source. try to modify theses values by yourself.

[byme]

thank you very much. I did some tests and whith the tweak I correct the defect



Now why ProCoder is still prefer that the image is cleaner than MeGUI

there is a way to improve the image by acting on some parameter of MeGUI?

What bitrate did you use? How big is the source frame and fps?

You can probably turn off or reduce the strength of psy-rd

[wyti]

You can use the "unrestricted 2Pass Insane" profile in Megui (very very slow)
OR postprocess your source (degrain, soften, deringing etc...)

Or you can simply continue to use ProCoder, if you prefer his results, why do you want to try another software ?

[CruNcher]

as wyti said if you want the same blurriness then the source you shouldn't use Psy-RD if you want a sharper result (like it could have been before being compressed, in your case from the look i think it's Mpeg-2 high quantizer) you should use Psy-RD :)

768x576 at 50 fps
bitrate 3000

for the reason mentioned in the title... I would use ProCoder but with the source at 50 fps the image is blurred (ghost effect)
I would be able to remove this flaw and maintain 50 fps, but I do not know how to do


ProCoder (with source at 50 fps to 25 fps)

MeGUI (with source at 50 fps)

ok thanks, certainly improves :) .. but still prefer ProCoder

btw.: the only colorspace one should feed to ProCoder is YUY2.
This is the only colorspace which leads to accurate colors in ProCoder.
