Note that the audio cache will always be created when opening files with audio and that it will be huge since it stores all audio as raw signed 16 bit pcm.
FFPP(clip, string pp, int ppquality = 6)
Separate postprocessing which also seems to include a few simple deinterlacers
source: Source file.
atrack & vtrack: Track number as seen by the relevant demuxer, starts from 0, -1 means it will pick the first suitable track and -2 means it's disabled.
timecodes: File to output timecodes to, if the file exists it will be overwritten.
vcache: Write video indexing information to a file for later use. This setting does not control if The video index is loaded which it always is if it exists.
vcachefile & acachefile: Specifies the file to store the index information or raw audio in, if nothing is specified (source).ffv(tracknumber)cache is used for video and (source).ffa(tracknumber)cache for audio.
accompression Audio cache compression, -1 means raw audio and 0-8 uses FLAC with that compression level.
pp: See the table below for a full description, an empty string means no processing. It is recommended to avoid the autoq option since it's currently unknown what effect it will have on the processing.
ppquality: The quality to use for the specified postprocessing. Valid values are 0-6 where 0 usually means that no actual processing is done.
seekmode:
Force how seeking is handled, has no effect on matroska files which always use the equivalent of seekmode=1
0: linear access, the definition of slow but should make some formats "usable"
1: safe normal, bases seeking decisions on the reported keyframe positions
2: unsafe normal, same as 1 but no error will be thrown if the exact destination has to be guessed
3: aggressive, seek in the forward direction even if no closer keyframe is known to exist, only useful for testing and containers where avformat doesn't report keyframes properly

hb hdeblock (2 threshold) horizontal deblocking filter
1. difference factor: default=32, higher -> more deblocking
2. flatness threshold: default=39, lower -> more deblocking
the h & v deblocking filters share these
so you can't set different thresholds for h / v
