I keep saying the same stuff over and over when it comes to analyzing videos. I can't immediately find a post that lists what makes a video acceptable for analysis, so I will just reproduce on here. I will give 1 point for each of the following that the video has:
- Stationary camera and background
- Camera does not zoom
- Motion perpendicular to the camera
- You can see the object in every frame (nothing obscuring the motion)
- Interesting physics content
- Downloadable (some videos I can't "get off the web")
- No repeating frames
- Not badly interlaced (or would that be deinterlaced - I get confused)
This gives a max score of 8 points. I think it would be best to just apply this to a select portion of a video (not necessarily the whole thing). I will call this the VAS.

This is for commenter JimP. How do you take into account uncertainty when using video analysis? A great question. The first thing to think about is where does the uncertainty come from? My first guess would that it would be from the user. Where does the user click? Is it right on the object…
Cats can be entertaining - especially when they are someone else's cat and that someone made a video. Really, this post is about analyzing video with Logger Pro (in a tutorial type fashion). I just happens that I chose this cat video to analyze. Here is the video:
