Because of its complex settingsit may take a long time to get the right feeling for this kind of effect. Some filters support a generic enable option. For the filterssupporting timeline editing, this option can be set to an expression which isevaluated before sending a frame to the filter.
- Set the target threshold value.
- Disables multiplane images.
- Ifenabled, the frames reconstruction will be based on the fields and frames fromthis second stream.
- Each of the expression options specifies the expression to use for computingthe lookup table for the corresponding pixel component values.
Set time of start of transition relative to first video. Set the chroma matrix vertical size. Range is [1, 23] and default value is 5. Specify interpolation used for remapping of pixels.
Filter Reference
Pick median pixels from several successive input video frames. This filter needs four video streams to perform thresholding. First stream is stream we are filtering. Second stream is holding threshold values, third stream is holding min values,and last, fourth stream is holding max values.
41 colorspace
Turning this on is highlyrecommended whenever quality is desired. Configures the size of scaler LUTs, ranging from 1 to 256. Thedefault of 0 will pick libplacebo’s internal default, typically64. The focus distance of the image/video (expected constant for video). Note thatfocus distance is only used for vignetting and only slightly affects thevignetting correction process.
Video Sinks
Allowed values are near and linear. Whether or not to do a tiny bit of cropping at the borders to cut down on the amount of mirrored pixels. Note that in order to see console debug output you will also need to pass -v verbose to ffmpeg. Flag which specifies the pixel to refer to. Range is [0, 255] and default value is 255, i.e. all eight pixels are used. Set multiplier for calculated value for each plane.
