Interesting bit of trivia on why the frame rate is '119.88' instead of 120: It's using the NTSC/ATSC frame-base of 1.001.
Ever since old TV standards moved from black and white to color within the US, the timing has been "frames per one and one onethousandth of a second". So 120/1.001 = 119.88.
Was a neat trick in the analog days to maintain compatibility with the older black and white TV sets. Fastforward to the digital age and that fractional timing difference makes keeping audio and video sync an absolute nightmare.
