Revision as of 08:23, 15 April 2020

Description

Script and plugin set to increase the frame rate with interpolation and fine artifact removal.

Requirements

• [x64]: AviSynth+
• Supported color formats: Y8, YV12, YV16, YV24

Required Plugins

Latest versions of the following filters are recommended unless stated otherwise.

• FrameRateConverter.dll
• MaskTools2
• MVTools
• GRunT - for debug only

Syntax and Parameters

FrameRateConverter.avsi

Script containing FrameRateConverter() and InterpolateDoubles() functions.

FrameRateConverter

FrameRateConverter (clip C, int "NewNum", int "NewDen", string "Preset", int "BlkSize", int "BlkSizeV", bool "FrameDouble", string "Output", bool "Debug", clip "Prefilter", int "MaskThr", int "MaskOcc", int "SkipThr", int "BlendOver", int "SkipOver", bool "Stp", int "Dct", int "DctRe", int "BlendRatio")

clip   =

Input clip.

int  NewNum =

The new framerate numerator (if FrameDouble = false, default = 60).

int  NewDen =

The new framerate denominator (if FrameDouble = false, default = 1)

string  Preset = "normal"

The speed/quality preset: [ "slowest" | "slower" | "slow" | "normal" | "fast" | "faster" | "anime" ]

int  BlkSize =

The block size; available sizes are 6, 8, 12, 16, 24, 32, 48 and 64.

Defaults for 4/3 video of height:

• 0-359: 8
• 360-749: 12
• 750-1199: 16
• 1200-1699: 24
• 1600-2160: 32

int  BlkSizeV = BlkSize

The vertical block size. (default = BlkSize)

bool  FrameDouble = true

Whether to double the frame rate and preserve original frames (default = true)

string  Output = "auto"

Output mode [ "auto" | "flow" | "over" | "none" | "raw" | "mask" | "skip" |" diff" | "stripe" ] (default = "auto")

auto=normal artifact masking; flow=interpolation only; over=mask as cyan overlay, stripes mask as yellow; none=ConvertFPS only; raw=raw mask;

mask=mask only; skip=mask used to Skip; diff=mask where alternate interpolation is better; stripe=mask used to cover stripes.

bool  Debug = false

Whether to display AverageLuma values of Skip, Mask and Raw. (Default = false)

clip  Prefilter = none

Specifies a prefilter such as RgTools' RemoveGrain(21). Recommended only when not using a denoiser (Default=none)

int  MaskThr = 120

The threshold where a block is considered bad, between 0 and 255. Smaller = stronger.

0 to disable artifact masking. (Default = 120)

int  MaskOcc = 105

Occlusion mask threshold, between 0 and 255. 0 to disable occlusion masking. (Default = 105)

int  SkipThr = 55

The threshold where a block is counted for the skip mask, between 0 and 255. Smaller = stronger.

Must be smaller (stronger) than MaskThr. (Default = 55)

int  BlendOver = 70

Try fallback block size when artifacts cover more than specified threshold, or 0 to disable.

If it fails again, it will revert to frame blending. (default = 70)

int  SkipOver = 210

Skip interpolation of frames when artifacts cover more than specified threshold, or 0 to disable. (Default = 210)

bool  Stp = true

Whether to detect and blend stripes (default=true)

int  Dct = 0

Overrides DCT parameter for MAnalyse (default: Normal=0, Slow=4, Slowest=1)

int  DctRe = 0

Overrides DCT parameter for MRecalculate (default: Fast=0, Normal=4, Slowest=1)

int  BlendRatio = 40

Changes the blend ratio used to fill artifact zones. 0 = frame copy and 100 = full blend.

Other values provide a result in-between to eliminate ghost effects. Default = 40.

InterpolateDoubles

Replace double frames with interpolated frames using FrameRateConverter.

InterpolateDoubles (clip C, float "Thr", bool "Show", string "Preset", int "BlkSize", int "BlkSizeV", int "MaskThr", int "MaskOcc", int "SkipThr", int "BlendOver", int "SkipOver", bool "Stp", int "Dct", int "DctRe")

clip   =

Input clip.

float  Thr = 0.1

Frames will be replaced when Luma difference with previous frame is greater than threshold (default=0.1)

bool  Show = false

If true, "FRAME FIXED" will be written on replaced frames (default=false)

All other parameters are the same as FrameRateConverter().

FrameRateConverter.dll

Script containing StripeMask(), ConvertFpsLimit(), and ConditionalFilterMT functions.

StripeMask

Builds a mask detecting horizontal and vertical straight lines and patterns, as MvTools tends to fail in such areas.
