Image speed + acceleration from video

  1. Feb 28, 2017 #1
    1. The problem statement, all variables and given/known data
    Hello
    I have a video that is 30 fps according to the video information (when i right click on the file). It is stated that the videos were filmed in slow motion at 1/10 of normal speed.

    I'm using a standard version of matlab to plot points (actual position) on a moving object; i need speed and acceleration data

    2. Relevant equations
    Speed = delta position * fps
    accel = delta speed * fps


    3. The attempt at a solution
    Are the speeds and accel = to the above equations but times ten ? i.e.

    Speed = delta distance * fps *10
    accel = delta speed * fps*10

    If the video was filmed at 1/10 of normal speed, doesn't that give you an actual frame rate of 300 fps?

    By the way, I don't know how you are measuring position, but you have to be careful that it can be hard to convert pixels to other units of length.
