[psnr]
Four character code that specifies the output video stream format
Type: Four
True if the filter is using hardware acceleration.
Note: This property is read only.
Type: Bool
Left margin of the region of interest.
Positive value measured in pixels from the left edge of the frame.
Type: Int32
Right margin of the region of interest.
Positive value measured in pixels from the right edge of the frame.
Type: Int32
The Peak Signal to Noise Ratio (PSNR) of the two frames.
This property will be set on the analysis sample by the analyzer. A value of INFINITY indicates identical frames.
Type: Double
Top margin of the region of interest.
Positive value measured in pixels from the top edge of the frame.
Type: Int32
Bottom margin of the region of interest.
Positive value measured in pixels from the bottom edge of the frame.
Type: Int32
The Peak Signal to Noise Ratio (PSNR) of all frames.
This property will be set on the analysis sample by the analyzer. A value of INFINITY indicates all frame are identical.
The global PSNR is only calculated for frames that are not identical.
Type: Double
The average Peak Signal to Noise Ratio (PSNR) of all frames.
This property will be set on the analysis sample by the analyzer. A value of INFINITY indicates all frame are identical.
The average PSNR is only calculated for frames that are not identical.
Type: Double
[ssim]
Four character code that specifies the output video stream format
Type: Four
True if the filter is using hardware acceleration.
Note: This property is read only.
Type: Bool
Top margin of the region of interest.
Positive value measured in pixels from the top edge of the frame.
Note: Defaults to the top margin of the clean aperture.
Type: Int32
Left margin of the region of interest.
Positive value measured in pixels from the left edge of the frame.
Note: Defaults to the left margin of the clean aperture.
Type: Int32
Right margin of the region of interest.
Positive value measured in pixels from the right edge of the frame.
Note: Defaults to the right margin of the clean aperture.
Type: Int32
Bottom margin of the region of interest.
Positive value measured in pixels from the bottom edge of the frame.
Note: Defaults to the bottom margin of the clean aperture.
Type: Int32
Adjusts the ganularity of the SSim calculation.
SSim is the convolution of an 8x8 window over the reference and analysis frames. This property changes the step size between window calculations. For example, rather than calculate the SSim over ever 8x8 block, setting a value of 2 will effectively skip every other horizontal and vertical block. This would result in roughly one quarter the computation time while sacrificing accuracy.
Note: Defaults to 1.
Type: Int32
Average structural similarity for all frames.
Note: Propety is set on the last analysis sample.
Type: Double
structural similarity for the current frames.
Note: Propety is set on the current analysis sample.
Type: Double
[vmaf]
Four character code that specifies the output video stream format
Type: Four
True if the filter is using hardware acceleration.
Note: This property is read only.
Type: Bool
Specifies the CPU affinity.
Type: UInt64
Specifies the number of threads to use.
Type: Int32
