resizemode Scale
By default, input is scaled to the output
resolution.
• Scale: Input is scaled to output resolution.
• Crop: This setting crops the input and
encodes to a rectangle within the input
image (at the center of the image) while
discarding the rest of the input image. The
output resolution is the portion of the input
that is encoded from the center. This may
be done instead of downscaling.
NOTE:
Cropping is disabled if resolution is
set to Auto, 960, or 1440, or if (output)
resolution is set to equal or larger than the
input resolution.
gopsize 120
The Group of Pictures size for the encoded
video.
1..1000
NOTE:
For intra-refresh mode, the GOP size
is the number of frames between the
sequence and picture parameter set NAL
transmission.
gopstructure IP
The GOP structure for the encoded video:
(See
“Framing” on page 89)
•
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.
