matlabuser12 - consider using VideoReader to read the data from file starting at a specific index. For example,

 % create the object
 vidObj = VideoReader('myVideo.mp4');

 % determine the number of frames per second
 framesPerSecond = get(vidObj,'FrameRate');

 % determine the number of frames
 numFrames = get(vidObj,'NumberOfFrames');

 % read all data from the 11th second
 video = read(vidObj,[framesPerSecond*10 + 1 numFrames]);

video will be an array of video frames which you should then be able to play. Try implementing this and see what happens!

What function is the "play video" function? ive been using mplay, but i cannot seem to find where to put in the start and stop frame once i get the info off of videoreader

See an example from the above link and look at the use of the movie function.

[matlabuser12]

the output from read(....) does not result in an array of frames. so movie function does not work.

What is your output from read?
