Saturation/Color of xvid help

Hi, I've been recently testing filters to sharpen my encodes. 1 thing I searched for were sharpen filters. WarpSharp, Msharp, and some blurs Convo3d and the like. I was wondering where I could find documentation on Warpsharp. I've searched through the forums and haven't been able to find any examples. Also, I had a question about the saturation of color on my encodes. On most of my encodes, the film color seems a little duller than the original. Is there a way to up saturation or fix this color issue? I have seen other encodes of the same movie. They seem to have such vibrant colors. Maybe it's my eyes playing tricks on me or there is I filter I haven't found using the search function. Can anyone help?

try filter TWEAK() It's an extrenal plugin for Avisynth 2.0x, and Internal for 2.5 . With this filter you can adjust "hue", "saturation", "contrast", "brightnest". The plugin filter for visynth 2.0x is made by D.Graft ( if I remember well ;) ), so you could find it here :

O ok, I shall try tweak. Does xvid actually make the video color a little off, or is that because of my avisynth script. I was also wondering, a little off topic, where can I find documentation of warpsharp. I've searched and all I've found is a thread of a example of Warpsharp(30), not too sure what that does or if that's a high value or not. Also for unfilter with xvid, I read that with the mpeg2dec3 and lumafilter=-2, black blocks would look less ugly, can something like this also work for edge noise, or noise introduced by mpeg quants?
