IFFERENCES
This appendix helps Videonics MXPro and MX-1 users transition to MXProDV.
It highlights key operational differences between MXProDV and the other
Videonics mixers.
DV Support Added
MXProDV lets you connect digital video (DV) sources to the mixer via IEEE
1394, (FireWire, i.LINK). MXProDV has three 1394 ports: two for inputs and
one for output. FireWire provides high speed, short distance transfer of digital
data. Audio and Video are both sent over the FireWire connection.
MXProDV accepts DV data from DV (and miniDV), DVCAM, DVCPRO and
Digital 8 camcorders and VCRs. These devices use 4:1:1 sampling (NTSC) or
4:2:0 sampling (PAL) and a 5:1 compression. High end broadcast DV devices,
such as Digital-S and DVCPRO50, use a different sampling [usually 4:2:2] and
compression [usually 3.3:1]; these cannot be used with MXProDV.
With MXProDV, your DV data can be mixed with your analog data (Y/C and
composite video and analog audio) in almost any combination, and you can
output your data in both DV and analog format.
DV audio is usually 4-channel (12-bit, 32 kHz) audio or 2-channel (16-bit,
48kHz) audio. MXProDV outputs either of these formats. Choose the format in
the Setup menu. The default is 4-channel output.
NOTE
If you use 4-channel audio output, you can use either 4-channel or 2-channel
DV audio inputs. However, if you select 2-channel audio output, your DV audio
inputs must be 2-channel, too. There are no restrictions on using analog audio
inputs.
