Is there any tool (free if possible, but commercial software is also OK), that allow to calculate how many frames per second there is in a video ?
By calculating "how many real frames per second" I did not mean a tool that return the FPS information stored in the video header (that windows explorer or any video editing tool like
VirtualDub can give).
I mean a tool that would take each frame, check if it is different from previous frame (with some threshold) and based on that will report FPS information.
For example a video source could have been recorded at 60 fps but if you check frames themselves its only 30 fps (each frame is "doubled").
Such tools exists, please check these videos (it seems same tool is used in both) :

In these videos, I'm not sure either this is a software or hardware solution. I'm looking for a software one.
