To reach 10 MB, resolutions are often scaled down to 320x240 or lower.
Most "new" 10 MB movies are camcorder recordings from theaters, then compressed to oblivion.
Traditional video compression standards (H.264, H.265, AV1) achieve compression ratios up to 1,000:1. A 90-minute movie at 1080p typically occupies 1–2 GB (1,000–2,000 MB). Reducing this to 10 MB would require a —far beyond conventional codecs’ capabilities. Recently, neural compression and content-adaptive encoding have pushed boundaries, making the 10 MB target a technical curiosity worth investigating.
