The Project: Add a operating date/time stamp on each and every figure of a video. (The result of digital video camera, and my father inquired about how can he add the timestamp(for the milliseconds resolution) permanently to the video.

A friend pointed me in order to opencv (emgucv actually) , and because of my personal preferences i tried my luck having opencv in python.

Also, placed the variable fps as near to the actual incoming video framerate as possible you can not change it after you have started writing frames. Ultimately, write the edited frame to a video file. A common potential problems I can foresee tend to be with the codecs, which I unfortunately do not know a lot about.
