Capacity For Capturing Uncompressed Media Via 3G-Sdi Inputs - Telestream Lightspeed Live Capture User Manual

Capacity for Capturing Uncompressed Media Via 3G-SDI
Inputs
Lightspeed Live Capture can capture Uncompressed SD or HD in 8-bit or 10-bit via the
3G-SDI inputs. Several factors determine what your Lightspeed Live Capture system is
able to reliably capture. Use the chart below to calculate the Resource Use Factor (RUF)
when capturing Uncompressed. A Lightspeed Live Capture server RUF value should
never exceed 1.
•
Storage Location—Local Media drive or Shared Storage of NAS (Network Attached
Storage), or SAN (Storage Area Network).
•
Drive Configuration—The drive configuration is governed by the number of
drives making up your Live Capture system's media drive and the RAID type that
the media drive is configured for. A standard Live Capture server ships with a media
drive containing 4 drives striped as RAID 5. In addition, a Lightspeed Live Capture
system's media drive can be expanded to 8 drives by purchasing the media drive
option "LS-LIVE-4TB-OPTION". The RAID type of the media drive can be changed
from RAID 5 by the user to RAID 0 if disk I/O is more desirable than data redun-
dancy. See
•
Frame Size, Frame Rate, and Scan Type—The incoming input's frame size, the
frame rate, and scan type of interlaced (i) or progressive (p) will affect the require-
ments for capturing an Uncompressed file output.
