Work out compression ratio for video instantly with clear inputs, formula shown and shareable results.
Compression ratio is the uncompressed bitrate divided by the delivery bitrate, and the data saved is the difference in bitrate integrated over the running time. Modern codecs run at ratios of 100:1 or more, which is why streaming a film that would be terabytes uncompressed is possible at all.
Compression ratio
ratio = uncompressed bitrate / compressed bitrate
Data saved
GB = (raw - compressed) Mbps x seconds / 8000
ratio = uncompressed bitrate / compressed bitrate. Compression ratio is the uncompressed bitrate divided by the delivery bitrate, and the data saved is the difference in bitrate integrated over the running time.
Modern codecs run at ratios of 100:1 or more, which is why streaming a film that would be terabytes uncompressed is possible at all.
Enter uncompressed bitrate, delivery bitrate, duration. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
