Disclaimer, not working for Netflix, but working in this area. Ultimately it will still likely to be ffmpeg or their internal fork of it? But they are talking about per-title/per-shot optimisation here and not apply a blanket quality profile for every single video. Netflix also produce their own series and allow them to optimise their encoding further. They also have a Video Validation Services and Video Quality Services that do automatic quality check of the encoded video as the post indicated. Is it complex, yes it is. But is it overly complex, maybe not?
