Video Bitrate Settings
Table 12 below summarizes the minimum and maximum bitrates supported by the XVC-ULTRA
Encoder for major video standards.
•
The
minimum bitrate
value depends on the video input standard. In addition, the
minimum bit rate scales proportionally with the frame rate selected. For example, if the
minimum bitrate for 2160p60 is 2812 Kbps, then the minimum bitrate for 2160p30 (a 50%
reduction in frame rate) will be 1406 Kbps (a 50% reduction in bitrate).
•
The
maximum bitrate
is always 60,000 Kbps.
•
For
AVC
add approximately 30-40% to each column.
