Techniques and tools for quality control in frame interpolation and motion
analysis are described. The techniques and tools may be implemented
separately or in combination in software and/or hardware devices for
various applications. For example, a media playback device uses quality
control in frame interpolation with motion analysis to increase the frame
rate of streamed video for playback. The device selectively uses frame
synthesis to increase frame rate and quality under normal circumstances,
but avoids using frame synthesis when it would not provide suitable
quality improvement. The device uses selective ghosting reduction and
selective feathering to reduce artifacts in synthesized frames.
