I've followed the guide on this site on encoding my mpeg-2 file using Tmpgenc Plus and having problem with my results. My source file is in avi and after encoding, my mpeg-2 in movie seems a lot darker than my source file. So i went to uncheck the option "Output basic YCbCr" under Quantize matrix and re-encode the second time. Second result was better, almost the same as the source file. But, having looked at it carefully, the second result still seemed a bit darker than the original source, even having "Output basic YCbCr" uncheck. Can someone help me find a way to encode my mpeg-2 file to have the same contrast/brightness as my original source file please? Anything would help.

i have the following codecs installed from Doom9.net:
1)ffdshow
2)Ogg Vorbis Direct Show filter implementation
3)XviD 1.0.2
4)DivX 3.11 alpha
5)Vobsub

The brightness and contrast are also influenced by the player. For example, MPEG files played back in the Quicktime Player tend to look a bit brighter than if they're played on PowerDVD (using the default settings).

So trying to get the two to match exactly is a bit pointless, because even if they match in one player, they might not match in a different one.

If you want it to look brighter, just add a "brightness" filter (either in TMPGEnc or in your video editing program).

And if you think the output of software players varies a lot, just wait until you start testing different set-top players and different TVs... Smile
