Hey, I was looking at the code source for your Screen Capture example, and I noticed a comment that said you were making sure not to write frames to the mp4 file too quickly because you'd overload the buffer. I think what actually breaks the system is when you try to write a frame using a timestamp that a frame has already been written to. So if the selected file frame rate is too low it could easily round off the timestamps in two new frame events so that they refer to the same frame. I've worked around this problem by using 240fps as my frame rate when opening the output file, a much higher frame rate than I'd expect any webcam to have.
