I'm looking at a mpeg-1 video from a red light ticket trying to see where I stopped before I turned right. It was a momentary stop, the kind where your car is only powered by the idle speed and you momentarily tap on the brakes to stop it. I stopped momentarily three times. The last time I stopped felt like a full 1/2 second at the time.
I'm looking for a momentary stop in the motion. I am assuming seeing two frames exactly the same would be a positive indicator of a stop. I am using Quicktime player and the forward arrow to look at each frame. I found the frames around the stop, but I still see a tiny difference of car to background on the contiguous frames. The background near the car moves with the car when flicking between the two frames.
Also when I look at the 1/2 second stop, it also shows very slight movement of car to background on contiguous frames. And The background near the car also moves with the car when flicking between the frames.
Can anyone explain this in terms of mpeg-1?
