Test scene: The Hong Kong extraction (Dark Knight). Look at the skyscraper windows. In a 1080p x264 encode (CRF 18), you see individual reflections. In a 720p encode, it’s a blur.

Your output will be: The.Dark.Knight.2008.1080p.BDRip.AAC.x264-CUSTOM

Q: Is "1080p BDRip x264" better than "2160p WEB-DL x265"?

Q: Why is "AAC" in the filename if the Blu-ray has DTS?

Q: What does a complete, proper filename look like?
