's digital composite D-3 format. A 120 min. D-3 tape will record 60 min. in D-5/D-5 HD mode. D-5 standard definition decks can be retrofitted to record high definition with the use of an external HD input/output box. The HD deck conversion does not allow for any error correction that exists on standard definition recordings, as the full bandwidth of the tape is required for the HD recording.

D-5 HD supports the 1080 and the 1035 interlaced line standards at both 60 Hz and 59.94 Hz field rates, all 720 progressive line standards and the 1080 progressive line standard at 24, 25 and 30 frame rates. Four 48 kHz 24-bit PCM audio channels, or eight 48 kHz 20-bit channels, are also supported. D-5 runs at different data rates for different formats (taken fro
