ffmpeg -i input.mov -c:v libsvtav1 -crf 22 -preset 5 -c:a libopus -b:a 256k output.mkvFilm archives face a paradox: digital preservation requires re-encoding every 10-15 years as storage media degrades. AV1 at CRF 22 can cut storage costs by 50% vs H.265 but the re-encoding compute cost for a million-title archive is substantial.
