Deinterlacement and Post Processing
VLC is able to deinterlace a video stream using different deinterlacement methods. Deinterlacement can be enabled in the Video menu, Deinterlacement menu item. The Blend methods gives the best results in most cases. The discard method is a less resource consuming alternative, although its results may be slightly compromised.
On some particular streams (MPEG 4, DIVX, XVID, Sorenson, etc.), some additional image filtering can be applied to the video before display, improving its quality in some cases. This can be enabled in the Video menu, Post processing menu item. Different levels of post processing can be chosen here. A higher level means more filtering.
Video filters
VLC features several filters able to change the video (distortion, brightness adjustment, motion blurring, etc.).
With the wxWidgets interface, filters can be easily enabled using the Extended GUI. In the Video tab, simply select the filters to enable. Image settings can be easily adjusted.

You can enable these filters through the Extended Controls panel on Mac OS X. Click on the triangle next to Video filters to select your filters or expand the Adjust Image section to change the contrast, hue, etc.

For better control, you need to go to the preferences. To select the filters to be enabled, go to Video, then to Filters. In the "video filter module" box, enter the names of the filters to enable, separated by semicommas. Filters will be applied in the selected order. Valid names are "clone", "wall", "transform", "adjust", "crop", "deinterlace", "distort", "motionblur" and "logo".
If you want to tune the behavior of these filters, go to Video, Filters, [your filter]. For each filter, you will find a short description and the options.
Audio filters
Equalizer
VLC features a 10-band graphical equalizer. You can display it by activating the advanced GUI on wxWidgets or by clicking the Equalizer button on the MacOS X interface.

Presets are available in the Audio menu in wxWidgets, or in the Equalizer window in the MacOS X interface.
Other audio filters
At the moment, VLC features two other audio filters: a volume normalizer and a filter providing sound spatialization with a headphone. They can be enabled in the Audio tab of the extended GUI for the wxWidgets interface and in the Audio section of the Extended Controls panel of the Mac OS X interface.
For better control, you need to go to the preferences. To select the filters to be enabled, go to Audio, then to Filters. In the "audio filters" box, enter the names of the filters to enable, separated by commas. Valid names are "equalizer", "normvol" and "headphone".
If you want to tune the behavior of these filters, go to Audio, Filters, [your filter]. The equalizer and headphone filters can be tuned.
