For example a *.wmv video length is 10 sec. Frame per second 50. Total frame= 10*50 =500 frames.
But Matlab NumberofFrames function gives 351 frames.
When same video start a blackframe, this time function gives 500 frames.
What can I do? What is problem? I think that the problem is Matlab videoreader function.

It might be a variable framerate movie. Or the recording process might not have been able to store frames fast enough leading to frames being skipped.

Was the video written using videoWriter class? If so then which MATLAB release are you using and which operating system?
