MSU FRC 0.5:
   The first public release

The filter is intended for video frame rate up-conversion. It increases the frame rate integer times. It allows, for example, to convert a video with 15 fps into a video with 30 fps.

Usage

To use the plugin, copy MSU_FRC.dll file to "plugins" directory in AviSynth install folder or use the function LoadPlugin directly from the script.

AviSynth script example:

AviSource("video.avi")
ConvertToYV12().MSU_FRC(4, "slow")

The input video must be in YV12 colorspace.
To convert a video into YV12 colorspace use ConvertToYV12.

The width and the height of the input video must be multiples of 16.
To resize a video use Crop and/or AddBorders.

Parameters

#	Description	Allowed values
1	Interpolation factor	Any positive number
2	Preset	fast - higher speed, lower quality medium - medium speed, medium quality slow - lower speed, better quality slow preset is used by default

AviSynth webpage http://avisynth.org

Examples

Test sequence "matrix". Interpolation factor is 4, slow preset.

Fragment of the "matrix" sequence (2 frames)

After processing the fragment on the left by the FRC filter the frame rate increased 4 times

Objective comparison with other algorithms

The figure below demonstrates the results of the objective comparison. The objective quality of processed sequences for various methods was measured using Y-PSNR. During PSNR calculation only interpolated frames were used. In order to do so the original video sequences were first decimated with factor 2 and then decimated frames were interpolated using FRC. After that the interpolated frames were compared with the original ones using Y-PSNR metric.
Vertical axis is marked by average Y-PSNR values for each sequence, the horizontal one - by the names of test video sequences. It can be seen that the developed algorithm shows the best objective quality on most sequences.

Public MSU video filters Here are available VirtualDub and AviSynth filters. For a given type of digital video filtration we typically develop a family of different algorithms and implementations. Generally there are also versions optimized for PC and hardware implementations (ASIC/FPGA/DSP). These optimized versions can be licensed to companies.
