cut video with beginning and end frame number

Hello!

I want to "cut" a shorter video out of a long video in Matlab. I have the start frame number and the end frame number.

For example a video lasts 30 seconds and I want to have only the new video from 4 seconds to 17 seconds by knowing the beginning frame number of hypothesised 125 and end frame number of 501.

Any ideas how to do this?

Thank you for your help and your time!

I'm not sure the size of your video data, but observe the following:

    x = rand(50,60,1000);
    whos x % x = [50, 60, 1000]
    x(:,:,[1:124,502:end]) = []; % delete beginning and end sections
    whos x % x = [50, 60, 377]
