    Those figures hold for DV, but Canopus Lossless ends up approx 1 GB/min.

    Canopus HQ rate will really vary on the type and nature of the footage. Some footage
    will compress very well, some will require extra bits.

    ADVC (non HD) series and DVStorm series both use Consumer DV compression (just like DV camcorders).

    EDIUS NX can capture as uncompressed, Canopus HQ, Canopus Lossless, or Consumer DV.

    Uncompressed is uncompressed.
    Canopus HQ is variable-bitrate usually ranging from 120 to 160 Mbps on average
    Canopus Lossless is mathematically lossless so compression ratio ranges between 1:1 and 2:1 for the majority of footage.
    Consumer DV is 25 Mbps.
