AE CS6 not telling correct framerate

Question

I have footage from my GoPro 3 imported into AE CS6 (PC)...
It is 720p (1280 x720) shot at what GoPro calls 120 fps.
Windows Explorer says its 119 fps in the Properties panel...
AE says its 59.94......
What gives?
Also, is there any way to see the fps and other video properties in Bridge, or does video not track exif data like that--or date, time, etc?

Answer 1

I don't know if anyone else is interested in the question I raised, or will be in the future, but I was able to answer my own question and verify what the wiki article quote above stated, that AVCHD lite cameras duplicate each frame of 30 fps video to produce a 720p60 bitstream. Maybe that is why cs6 calls the clip 30fps and windows explorer calls it 59fps.
The way I verified this was to video my digital stopwatch face which displays time in 1/100th of a second increments. I captured a couple of seconds of the stop watch running.  I then used the free open source software ffmpeg to extract 60 jpeg frames per second from the clip file and viewed each jpg frame.
Every other frame in the clip was identical, so although there were 60 frames there were 30 duplicates. So in a way, both cs6 and explorer were correct in their labeling of the clip's fps.
I then wanted to see if it was better to set the clip sequence in cs6 to AVCHD 1280x720 59.97 fps or allow cs6 to change the setting to 30fps when I brought the clip into the timeline.
To find out, I created two projects. In one I kept the 59.97 fps setting and in the other I allowed cs6 to change the clip settings to 30fps non drop frame timecode.
In both projects I used the speed setting to lower the speed to 2%, so each of the two second clips lasted about a minute and a half in slow motion.
This experiment did verify my initial impression that clips imported at 59.97 fps had more contrast and clarity than allowing cs6 to change the sequence setting to 30fps. Since I was looking at a closeup of a digital stop watch face showing elapsed time readout in 100th of a second increments at 50x slow motion, it was easy to see that lowering the fps to 30fps made the digital number display a bit less clear.
A final bit of information I learned was that in the course of one second my camera only captured
18 distinct 100th of a second digital time readings.  It seems the capture speed lags in clusters of time rather than being a uniform stream of 30 captures in one second.  Maybe I should try a faster rated memory card.
