Solarization using MPEG2DEC3.DLL with Avisynth 2.5
 

All,
I had a solarization issue some time ago when using Windows 98 or Win2K and Avisynth 2.0 that I resolved with the fix described in the FAQ. I am now using Windows XP SP1 and have upgraded recently to Avisynth 2.5.2.0 and had a couple of decent encodes with this using the MA script. Now, I am using ATI AIW captures from Dish Network via SVID but I don't think that has anything to do with the problem. The solution in the FAQ didn't help this time.

If I load the d2v file into TMPGEnc it looks fine. The AVS file has terrible solarization. I just tested for the cause by systematically removing ALL of the filter lines in the AVS file to see what the cause was. Nothing helped till I substituted MEPG2DEC.DLL (mpeg2dec_25_dll_20030107.zip) for MPEG2DEC3.DLL :idea: After that the solarization was gone, although now the left half of the image was lighter than the right. I had to remove the asharp(1, 4) line to get rid of that. Now it looks pretty good.

I have gotten way behind on all the new stuff going on, no time any more. I can't even follow most of what you all are talking about :roll: I'm just trying to make some decent encodes of my captures. Has anyone else had any issues like this?

Thanks,
Geoff

Can you post any screenshots?

Sure. Hopefully these will show what's happening.

You should get a good view of the blotchy areas.

It looks this way in TMPEGenc too when I'm in the source range area.

Thanks,

Use the "DirectX 8.1 fix" found at the bottom of the CVS Binary page found in my signature.

For TMPGEnc end your scripts with ConvertToRGB24(), and you won't have these problems.

I think this is the same problem that I posted about in:

I never found an acceptable solution.

I will try Shodan's fix.

So, who wrote that :
? :-)

sh0dan,
i'm using DirectX 9.0b(4.09.0000.0902) for win98se(4.10,compilation2222),

i need the DirectX 8.1 fix :?:
:?

Jorel, if you do not have the solarization problem, for sur you do not need any fix :-)

right Phil !

i am (was) thinking to do one sample with each "Directx"
to see if have any difference!

you know what i mean,
using the same "everything" changing only the DirectX versions :!:

thanks !
:wink:

I'm not sure M$ let you reinstall Divx8.1 after you had installed 9.0. There is no "uninstall directx" button anywhere (at least in winXP).

Thanks a lot Sh0dan. I also have DirectX 9.0 now, so no option there. However, adding ConvertToRGB24() to the end of the script does indeed seem to have taken care of the problem. This will allow me to utilize all the other options in the script.
Does ConvertToRGB24() (theoretically) have any significant disadvantages?

Thanks,
Geoff

oh yes i can.....
i have a "hacked" program to uninstall DirectX!

:lol:
