9. A method of converting input video frames received at a first rate into output frames provided at a second rate, said input video frames containing a blend of a first and a second video content having a first and a second cadence respectively, said method comprising:
i) detecting said first cadence and said second cadence; and
ii) providing said output frames by selectively interpolating said input video frames based on said first and second cadence so as to reduce judder in said first and second content in said output frames.
