New video issues

[abc1110]

When I try to run the same code with some other video file, I get a highly magnified video and hence much of the original video data is getting lost.

How can I configure it to avoid such a problem, because as of now I cannot choose the points I desire for ROI

Thanks!

This happens because the resolution of the video is too large to fir the screen.
Just double click on the title of the cv2 window and it will fit your screen.
