Conclusion Encoding "The Penguin S01" with FFmpeg requires 10-bit pipelines, HDR metadata preservation, and grain management . Use libx265 with preset=slower and CRF 16-20 for archive-grade quality, or libsvtav1 with film-grain synthesis for size-optimized streaming. Always validate with VMAF and check HDR signaling on target playback devices. Avoid aggressive denoising – the show’s aesthetic depends on retained grain. # Compare VMAF (requires libvmaf) ffmpeg -i reference
