Encoded in 8-bit HEVC using -preset slow, crf = 24, -tune grain. Audio first converted to lossless FLAC and then to AAC using Foobar. Since the audio is monaural (1 Channel), Foobar automatically adjusted bitrate of the audio at an average of 100 kbps, which gives optimum audio quality for LC-AAC. Even audiophiles will have difficulty in distinguishing from the original DTS track.
For comparison, 6 Channel (5.1 Surround) AAC Tracks require an optimum variable bitrate of around 540-600 kbps.
As for the video, I realised that going below crf 24 won't be any beneficial.

This is my first attempt at encoding. Have fun.
