View Full Version : Matrix too dark after encoding

Hi,

Firstly, I didn't really know where to post this.

The problem is with The Matrix, when I watch the original DVD with PowerDVD it looks good, no real problems with the darkness/brightness.

After I rip it, the VOBs are still good in PowerDVD, but the D2V, the AVS, and the DivX5 files are all way too dark in WMP 6.4, and Zoom Player.

For the DivX5, it's a 2CD 700MB encode, and I'm using ffdshow (Dec 11) to decode. It's looks okay if I either: enable the luminance level fix in the mplayer processing method of ffdshow, or by playing around with the luminance gain and offset. The problem with this is that, the DivX5 artifacts become really obvious.

So, I'm looking for a filter or something that will do the same as the luminance level fix in ffdshow, but I want to do that *before* I encode to DivX5.

Does anyone have any suggestions?

Hi-

You can add the Tweak Filter to your .avs script before encoding. It's built into the AviSynth version included in the latest GKnot, so there's no need to add the plugin. So something like:

Tweak(Bright=10)

might do it for you. You can use any number between 0 and 255 to make it brighter. For other things you can do with it, check here:

Tweak Information (http://www.avisynth.org/index.php?page=Tweak)

You may or may not want to tone down the contrast after brightening it up. For other filters already built into AviSynth 2.07, check here:

AviSynth Filters (http://www.avisynth.org/index.php?page=FiltersByCategory)

The Levels Filter can do the same thing, but I find it trickier to use. And for other third party filters you can get and then load the Plugin to use, go here:

Try this (easier?):
Open your .d2v-file with notepad and change "Luminance=128,0" to "Luminance=138,10" or something.

OK, Thanks.

I used Tweak(Bright=10) in the AVS and the output is much better.
