each amovie filter use stereo file with IR coefficients as input.
The files give coefficients for each position of virtual loudspeaker:
@example
-ffmpeg -i input.wav -lavfi-complex "amovie=azi_270_ele_0_DFC.wav[sr],amovie=azi_90_ele_0_DFC.wav[sl],amovie=azi_225_ele_0_DFC.wav[br],amovie=azi_135_ele_0_DFC.wav[bl],amovie=azi_0_ele_0_DFC.wav,asplit[fc][lfe],amovie=azi_35_ele_0_DFC.wav[fl],amovie=azi_325_ele_0_DFC.wav[fr],[a:0][fl][fr][fc][lfe][bl][br][sl][sr]headphone=FL|FR|FC|LFE|BL|BR|SL|SR"

@example

By default value 0xf, all planes will be processed.
@end table
+@section maskfun
+Create mask from input video.
+
+For example it is useful to create motion masks after @code{tblend} filter.
+
+This filter accepts the following options:
+
+@table @option
+@item low
+Set low threshold. Any pixel component lower or exact than this value will be set to 0.
+
+@item high
+Set high threshold. Any pixel component higher than this value will be set to max value
+allowed for current pixel format.
+
+@item planes
+Set planes to filter, by default all available planes are filtered.
+
+@item fill
+Fill all frame pixels with this value.
+
+@item sum
+Set max average pixel value for frame. If sum of all pixel components is higher that this
+average, output frame will be completely filled with value set by @var{fill} option.
+Typically useful for scene changes when used in combination with @code{tblend} filter.

@section mcdeint
Apply motion-compensation deinterlacing.
@table @option
@item s
-Set denoising strength.
+Set denoising strength. Default is 1.0. Must be in range [1.0, 30.0].
@item p
-Set patch size.
+Set patch size. Default is 7. Must be odd number in range [0, 99].
@item pc
Same as @option{p} but for chroma planes.
The default value is @var{0} and means automatic.
@item r
-Set research size.
+Set research size. Default is 15. Must be odd number in range [0, 99].
@item rc
Same as @option{r} but for chroma planes.
