The manual de-blocking and de-ringing controls do not control the strength of the
post-processing, but rather where and how it is applied.
Each pixel in a DivX video is composed of three color channels—one luminance
channel and two chrominance channels. The eye is most sensitive to changes in
the luminance channel and so de-blocking gives preference to this.
The film effect restores warmth to the image and masks the artificial smoothing
effect that can result from low-bitrate encoding by applying a film grain effect to
the picture.
The film effect is particularly useful in counteracting the
effects of strong source
pre-processing applied
during encoding.
