EVS XS - Important Recommendations

Backup
Maximum transfer speeds through the Gigabit ports of the XS server:
• 6 simultaneous real time transfers with Avid DNxHD® 85Mbps
• 6.2 x faster than real time on a single transfers with Avid DNxHD® 85Mbps
• 6 simultaneous real time transfers with Avid DNxHD® 100Mbps
• 5.3 x faster than real time on a single transfers with Avid DNxHD® 100Mbps
• 5.8 simultaneous real time transfers with Avid DNxHD® or Apple ProRes 422 at
120Mbps (PAL)
• 4.6 x faster than real time on a single transfers with Avid DNxHD® or Apple ProRes
422 at 120Mbps (PAL)
• 4.8 simultaneous real time transfers with Avid DNxHD® or Apple ProRes 422 at
145Mbps (NTSC)
• 3.8 x faster than real time on a single transfers with Avid DNxHD® or Apple ProRes
422 at 145Mbps (NTSC)
Restore
Maximum transfer speeds through the Gigabit ports of the XS server:
• 6 simultaneous real time transfers with Avid DNxHD® 85Mbps
• 4x faster than real time on a single transfers with Avid DNxHD® 85Mbps
• 5.7 simultaneous real time transfers with Avid DNxHD® 100Mbps
• 3.4 x faster than real time on a single transfers with Avid DNxHD® 100Mbps
• 5 simultaneous real time transfers with Avid DNxHD® or Apple ProRes 422 at
120Mbps (PAL)
• 3 x faster than real time on a single transfers with Avid DNxHD® or Apple ProRes 422
at 120Mbps (PAL)
• 4.1 simultaneous real time transfers with Avid DNxHD® or Apple ProRes 422 at
145Mbps (NTSC)
• 2.5 x faster than real time on a single transfers with Avid DNxHD® or Apple ProRes
422 at 145Mbps (NTSC)
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 220Mbps (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 145Mbps (NTSC) or 185Mbps (PAL).
• When using the Avid DNxHD® codec, we advise to work at 100Mbps if the picture
quality is satisfactory à the XS 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.
