A metric that I will use is the Mutual Information Measure,
This metric measure the temporal correlation between frames in a
video i. e. measure the amount of redundancy between two frames.

I don't know if this metric is implemented in ffmpeg. But, I have to
use it. Then, I will implement it in ffmpeg in future

Hi All,
Is there existing metrics quantifying amount of motion in video
scene?
Thanks,

There is a filter in ffdshow (and, presumably, somewhere in ffmpeg)
that
shows motion vectors. A summ of these vectors' length could be a
metric
value.
Also, you could try to calculate SSIM index for two consecutive frames
and use the index value (it will show you the difference between two
frames, which usually means motion, except for scene changes
maybe...).
