I used .mp4 video to form frames by using VideoReader and then i combined them again to form a new video by using VideoWriter ,but i got .avi file. How can i automatically get the same extension video which i used at starting?

I'm not very familiar with VideoWriter, but looking at the documentation it looks like you can specify the file format using a second parameter. It looks like you put a profile for the second parameter and in that profile you can adjust the property FileFormat to make a .mp4
