| Traditional Rule | Heretic H265 Approach | |----------------|-----------------------| | Use a standard CRF (Constant Rate Factor) like 18-22 | Use CRF 28-32 or higher, plus aggressive noise reduction | | Preserve film grain for authenticity | Apply strong denoising to save bits | | Keep audio as high-bitrate AAC or AC3 | Use Opus at very low bitrates (e.g., 64kbps for 5.1) | | Encode for broad device compatibility | Use 10-bit encoding even for 8-bit source (improves compression, but breaks old hardware) |
Want to test it yourself? Use ffmpeg with x265 and experiment with CRF values above 28, plus -x265-params "no-sao=1:aq-mode=4" . Just don't be surprised if purists call you a heretic.
