how to change FramesPerSecond

I have an avi video and I need to change the FramePerSecond for splitting the video into frames.

              Filename: 'movie.avi'
              FileSize: 6536192
           FileModDate: '11-Apr-2005 19:02:30'
             NumFrames: 84
       FramesPerSecond: 25
                 Width: 180
                Height: 144
             ImageType: 'truecolor'
      VideoCompression: 'none'
               Quality: 0
    NumColormapEntries: 0

Is it possible to change the FramePerSecond which should results me the few NumFrames??

Why do you need to change the frequency if you only want to extract the frames?

[Berbia]

yes, I need to extract frames but the time difference between two frames should be less than actual (around 15 fps).

But why? When you have the single frames the frequency does not matter.

I perform further operations on combining successive frames, that's why I need this??

You find a lot of tools for this in the net. Simply search for them:

I'd personally try it with VLC.

 mov=aviread('movie.avi');
 size(mov)=[1 84];

is it possible to reduce the columnsize by coding??
