...
Another way is to use an array as a type, e.g.:
Video[] videoArray = gson.fromJson(json, Video[].class);

Is a Java string really immutable?
...was actually a bit surprising to me, as I thought it would share the value array (it did in earlier version of Java, before Java 7u6).

Understanding FFT output
... imaginative part of a complex number (that what's your real and imaginary array is). Instead you want to look for the magnitude of the frequency which is defined as sqrt (real * real + imag * imag). This number will always be positive.
