You forgot to attach your csvfile, so about all I can say is:
data = csvread(filename);
ft = fft(data);

I'm not going to watch that whole long video. If you want, you can tell me at what time in the video they're exporting/saving the output that you need to use, and I might take a look at it.
ft is a variable that is the output of the fft() routine. The help for the fft() routine says that it returns "the discrete Fourier transform (DFT) of X using a fast Fourier transform (FFT) algorithm." In my variable, the "f" in "ft" means Fourier, and the "t" in "ft" means transform.
