Frame-rate conversion is essential for providing smooth video playback in applications with strictly limited bandwidth, such as cell phone networks, and for preventing video flickering and motion jitter effects on large LCD, CRT or plasma displays.

Our solution uses complex motion estimation algorithms to create high-quality interpolated frames, thus increasing the video frame rate. The main advantage of our solution is that it is robust with respect to motion complexity. Even in cases of complicated motion, and unlike other algorithms of this kind, the YUV FRC algorithm produces high-quality interpolated frames.

Here is an example output for a case of complex motion (red lines are superimposed for convenience):

Examples of Work

This example shows comparison results for the “Stefan” test video sequence:

Retimer FRC	Motion Perfect FRC
Twixtor FRC	YUV FRC

The diagram below shows the objective comparison result based on the PSNR metric. The higher values of PSNR indicate higher quality in the video sequence. The horizontal axis of the chart is labeled with the names of the test video sequences. The vertical axis is labeled with the average PSNR values for each test video sequence. YUV FRC yields the best results for the majority of the test sequences.
