Image speed + acceleration from video

AI Thread Summary
The discussion revolves around calculating speed and acceleration from a slow-motion video recorded at 30 fps, which plays back at 1/10 of normal speed. The user seeks clarification on whether to adjust their speed and acceleration equations by multiplying by ten due to the slow-motion effect. It is suggested that the effective frame rate for calculations could be considered as 300 fps, given the slow-motion factor. Additionally, caution is advised regarding the conversion of pixel measurements to physical units. Accurate measurement methods are crucial for reliable data analysis in this context.

Homework Statement


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

Homework Equations


Speed = delta position * fps
accel = delta speed * fps[/B]

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.
