Post-processing level in DivX encoding?

[otwist26]

If I understand it correctly, the "post-processing" level of the DivX (in this case DivX4.12) codec is a set of algorithms that attempt to clean up the video stream during playback/decoding.

I also understand how to change the post-processing level while playing a video in WindowsMediaPlayer.

What I do not understand is what the "default post-processing level" actually does during the encoding process? Let's say I'm encoding a DivX4.12 video with VirtualDub. What effect will changing these levels (in the codec configuration box) have an the encoded stream? Why is this option even there?

Can anyone explain this?

thanks!

nothing, it doesn´t do anything to the actual encoding process... that´s why it´s called POST-processing.
the oprion is there just beacuse... no explanation....
you should upgrade to divx 5.0.2 (not .3 or .5 cuase i´ve heard of several problems with this versions...)

you may hear quite a lot, but maybe you should only post when your *knowledge* is based on true experience!

5.05 works fine - no matter what you heard or who said so.

otwist26,

I would speculate that the "default post-processing level" setting refers exactly to the default post-processing filter setting that will be in place when playing or decoding a movie using the DivX 4.12 (and all versions of DivX 5). So let's say you play a video using the DivX 4.12 decoder and you have set the default post-processing level to 0, the decoder will start the rendering with 0 number of post-processing filters active. Similar things occur when you set it higher up to the maximum.

As Satan Claus put it, this particular setting will have no effect in encoding; only in playback or decoding does it play its role.
