Sheldon finally achieves a satisfactory digital copy of "The Raiders of the Lost Ark". He learns that, sometimes, "good enough" is, well, good enough.

Sheldon is frustrated with the video quality of his favorite TV show, "The Raiders of the Lost Ark". He wants to create a digital copy of the movie, but his current video encoding settings are not producing the desired quality. He decides to use ffmpeg to optimize the encoding process. I hope you enjoy it
FFmpeg uses algorithms like the Fast Fourier Transform (FFT) to perform tasks like video and audio encoding. The FFT is an efficient method for calculating the discrete Fourier transform (DFT) of a sequence. In simple terms, it helps convert a signal from its time domain representation to its frequency domain representation.
$$DFT(x_n) = \sum_{k=0}^{N-1} x_n \cdot e^{-j2\pi kn/N}$$
