Whenever I download a Motion Event video from my 24/7 Camera history, the clip is in MPEG-2 format and it is only 15-seconds long. However, if that same clip is then converted to a MP4 video, there is now significantly more footage (anywhere from 45 to 90 seconds long), and its not slowed down. There's just that much more footage. Its like there is a lock on the MPEG-2 video that only allows for 15-seconds of viewing.
Why is that?
