 Summary of Filters
 =============================
 
-Coming Soon!
 
 HandBrake contains the following filters:

   - Decomb
 - Denoise
 - Deblock
+- Chroma Smooth
 - Grayscale
-- Rotation
+- Colorspace
+
+
+Detelecine
+----------
+
+Detelecine removes comb artifacts that are the result of telecine, a process for converting film frame rates to television frame rates.
+
+
+Deinterlace
+-----------
+
+Deinterlace removes comb artifacts from the picture. 
+Yadif is a popular and fast deinterlacer. 
+Decomb switches between multiple interpolation algorithms for speed and quality.
+
+The following Deinterlace tunes are available:
+- Default: Is well balanced for speed and quality.
+- Skip Spatial Check: Lets Yadif skip correcting certain avoidable artifacts for a slight speed boost.
+- EEDI2: Uses a slower, higher quality interpolation algorithm for Decomb. Useful for the most difficult sources.
+- Bob: Attempts to better preserve motion for a slight penalty to perceived resolution.
+
+
+Denoise
+-------
+
+Denoise reduces or removes the appearance of noise and grain. This can improve compression efficiency and create higher quality video at smaller file sizes. 
+Overly strong Denoise settings may damage picture quality by discarding detail.
+
+NLMeans is a high quality denoise filter with a cost to speed. Use where quality is more important than speed.
+HQDN3D is an adaptive low-pass filter, faster than NLMeans but less effective at preserving fine detail.
+
+The following Denoise tunes are available:
+- None: Uses the default preset settings.
+- Film: Refines settings for use with most live action content.
+- Grain: Only processes color channels. Useful for preserving the film-like look of luminance grain while reducing or removing color noise.
+- High Motion: Reduces color smearing in high motion scenes by avoiding temporal processing for color channels. Useful for sports and action videos.
+- Animation: Is useful for cel animation such as anime and cartoons.
+- Tape: Is useful for low-detail analog tape sources such as VHS, where Film does not produce a desirable result.
+- Sprite: Is useful for 1-/4-/8-/16-bit 2-dimensional games. Sprite is not designed for high definition video.
+
+
+Deblock
+-------
+
+Deblock reduces blocky artifacts caused by low quality video compression.
+
+
+Chroma Smooth
+-------------
+
+Reduces chroma noise, rainbows, and other prominent visual artifacts. Useful for resolving various color-related issues, especially with lower resolution content from analog sources, e.g. not great DVD and VHS sources. The blurring/smoothing algorithm is the same as used by the unsharp filter.
+
+
+Grayscale
+---------
+
+Grayscale removes the color component of the video. Often referred to as Black & White video.
+
+
+Colorspace
+----------
+
+Colorspace + tonemap filter. Can change/tonemap the colorspace of the video into one of the following:
+
+- BT.2020
+- BT.709
+- BT.601 SMPTE-C
+- BT.601 EBU
+
+If this set to "Off" then HandBrake will keep the colorspace of the video.
