Video Compression Ratio Calculator
Compare an encoded file against its uncompressed size to get the compression ratio and bits-per-pixel — a quick quality/efficiency gauge.
Bits-per-pixel normalizes bitrate across resolutions: 15 Mbit/s looks great at 1080p (~0.36 bpp) but stretched thin at 4K (~0.07 bpp). Modern codecs hold up below 0.1 bpp on easy content; complex, grainy footage needs more. It's the fairest way to judge whether a bitrate suits a raster.
