Looking for an accurate Playback FPS from a video I've made a 1080P video using After Effects, and after it has been rendered the playback is a bit stutter-y. Now I am fairly certain that this stuttering is a result of the computer struggling with the playback, but I need to be able to prove this.

I was kinda hoping VLC has a way of displaying the FPS of the video being played, but as far as I can tell it has no such thing (only display the FPS of the rendering).

Can anyone point me in the direction of some software that will give me the Playback FPS of a video?

Many thanks!
Personally, I use fraps. The only reason I use fraps is because I used to record desktop footage a ton. However, if you get the free version of fraps, it should allow you to see the framerate of the video playing back while the program is open.
