Framing
IP
Select the video compression mode for the
encoded video:
●
I: I frames only (lowest delay; lowest
quality)
●
IP: I and P frames only
●
IBP: I, B and P frames (H.264 only)
●
IBBP: I, BB (two B frames in sequence)
and P frames (highest delay; highest
quality) (H.264 only)
NOTE:
B frames require a Main Profile
decoder.
B frames provide more quality as the
encoding is more efficient; thus more details
can be rendered in the same
bandwidth/bitrate.
TIP:
When B frames are used, the GOP may
be rounded up to make the sequence end
with a P frame.

Advanced Parameters
Aspect Ratio
Automatic
Specifies the aspect ratio of the video source
and signals it into the MPEG stream:
●
Automatic: Aspect ratio is derived from the
incoming video source resolution.
●
Manually force aspect ratio to either: 3:2,
4:3, 5:3, 5:4, 16:9, 16:10, or 17:9.
●
WSS/AFD: Aspect ratio is extracted from
the incoming video source based on WSS
(Wide Screen Signaling) or AFD (Active
Format Description) if detected.
NOTE:
WSS is only supported with analog
PAL video; AFD is only supported with SD-
SDI video.
