Simultaneous backup and restore
The backup sessions reach higher bandwidth and pre-empt the bandwidth against the
restore sessions. On a ‘per session’ based, the system allocate between 3.75 and 6 times
more bandwidth to backup session than to restore session.
4.4.6. Important Recommendations
For 6-channel configuration, maximum bitrates for Avid DNxHD® or Apple ProRes
422 should be 220Mbps (NTSC) or 185Mbps (PAL).
Super Motion + 1 Cam configuration (i.e. 1 Super Motion REC + 1 Std REC + 1
Super Motion PLAY + 1 Std PLAY): maximum bitrates for Avid DNxHD® or Apple
ProRes 422 should be 145Mbps (NTSC) or 185Mbps (PAL).
When using the Avid DNxHD® codec, we advise to work at 100Mbps if the picture
quality is satisfactory à the XT3 can sustain 6 local channels + 5 network transfers.
The 4ch configurations with 3D, 1080p or 3D SLSM 3x are only possible with Avid
DNxHD® 100 Mbps or Apple ProRes 422 LT.
