I know this is an old video. But I was just wondering how could I take this now modified video and export it as an avi file? Instead of just closing down the window

Thanks for the video. tried it with another video with a screenshot and it throws an error. error: (-209:Sizes of input arguments do not match) The operation is neither 'array op array' (where arrays have the same size and the same number of channels), nor 'array op scalar', nor 'scalar op array' in function 'cv::arithm_op'

Tried with webcam also but it didnt work. can you please give the tip? If you could check with a webcam as well..
