Number of Channels Per Card:
• It is only possible to encode one UHD stream.
• It is only possible to encode three 1080p streams.
• It is possible to encode up to four 720p/1080i streams.
• In Super Low Delay mode, it is only possible to encode one channel of HEVC
video (any resolution).
• In Super Low Delay mode, it is not possible to encode H.264 video.
Notes: First Release (release 9.29):
The same video format must be present across all channels in this first
release.
In subsequent releases (release TBD):
If the first channel is configured to 720p or 1080p, channels 2-3 may be
configured to be either 720p or 1080i.
If the first channel is configured to 1080i, channels 2-3 may only be
configured to be 1080i.
Available Encoding Profiles/Levels When Using Multiple Channels
When using multiple channels, the available encoding profiles/levels are dictated by
the profile/level selected on channel 1. The profiles/levels for channels 2 to 4 must
come from the same group, as shown in the table below.
