Anime archival for a private collection. H.265 with CRF 22 and slower preset to preserve cel animation detail (flat colors and sharp lines compress exceptionally well with HEVC), MKV for multiple subtitle tracks (Japanese + English).

ffmpeg -i input.mkv -c:v libx265 -crf 22 -preset slower -c:a aac -b:a 128k output.mkvAnime compresses 40-60% better than live action at the same CRF because flat-shaded cel animation has lower spatial complexity. An H.265 CRF 22 anime episode at 1080p typically lands around 300-500 MB vs 1-2 GB for live action.
