Set size of frame in number of samples which will be processed at once. Allowed range is from 1024 to 96000. When using the filter with wav, note the default encoding for wav is 16-bit,so the resulting 20-bit stream will be truncated back to 16-bit. Use somethinglike -acodec pcm_s24le after the filter to get 24-bit PCM output. Specify which channels to filter, by default all available channels are filtered. This can be useful to remove a DC offset (caused perhaps by a hardware problemin the recording chain) from the audio.
- Only used if plugin have zero inputs.
- If set to 0, it is disabled.
- Simple non-linear, global tone mapping algorithm.
- The Presentation TimeStamp of the input frame, expressed as a number oftime base units.
- Specify the amount of time that non-silence must be detected before it stopstrimming audio.
- Useful to improve output quality with focus option values greater than 0.0.
Simulates a tripod by preventing any camera movement whatsoever from the original frame. Range is [1, 1024] and default value is 0. If zero, sizeX value will be used. Pass the hardware device called name to all filters in any filter graph. Obtain the average VMAF motion score of a video. It is one of the component metrics of VMAF.
Options for filters with several inputs (framesync)
Set output gain for each band. Default value is 1 for all bands. Default is rms which is mostly smoother. Add filter to one of your lists below, or create a new one.

Display sample values of color channels. Mainly useful for checking colorand levels. Minimum supported resolution is 640x480. The output width and height (the size of the padded area), asspecified by the width and height expressions. Larger depth values will denoise lower frequency components more, butslow down filtering. This filter supports same commands as options, excluding smoothing option.
