The "Placebo" preset with 4:4:4 chroma and 250-frame lookahead is approximately 8x slower than standard "Veryfast" x264. An hour of 4K footage could take 24+ hours to encode on a consumer laptop. pppe264 full
Because PPPE264 is not part of the official VideoLAN x264 tree, some builds may have memory leaks. Always run a validation encode (10 seconds of representative footage) before batching your entire library. The Future: Is PPPE264 Full Obsolete Amidst AV1 and VVC? With AV1 and H.266 (VVC) offering 50% better compression than H.264, why invest in PPPE264 full? pppe264_full --input input
