Frame Rate Divider
1
, 2, 4, 6
Used to encode at less than the input frame rate
(for example, an input frame rate of 30fps with a
divider of 2 would cause an output stream of
15fps). If interlaced input is used then this is used
to reduce the number of fields being encoded.
[Note 2]
Number of B-frames
0
– 2 (
0
)
The number of B-frames. A value of “0” means B-
frames are disabled.
DEI Mode
None
Top Only
Full DEI
Interlace
For cases of interlaced input, specifies the
deinterlacing mode. “Top Only” means use the top
field only and resize. “Full DEI” means activate full
deinterlacing on the frame to generate a
progressive frame. “Interlace” generates an
interlaced frame for both interlaced and
progressive inputs.
GOP Size
10 – 240 frames (
60
)
I-frame frequency. [
Note 3
]
Maximum Delay
0 – 3000 (
2000
)
# of ms to buffer. The higher the value, the
smoother the encode, but also the higher the
latency (see Section 7.11, “Tuning for Latency” on
page 31).
Audio Enable
True
, False
True -> Encode audio.
Audio Info
(Entries for each of the 4 subchannels within the source)
Enable
yes (for Sub Channel 1)
no
Used to select which subchannel should be used for
the audio source. Only one subchannel can be
enabled.
Codec
DSP AACLC
DSP AACHE V1
DSP AACHE V2
ARM AACLC
ARM AACLC MPEG2
ARM AACHE
ARM AACHE V2
The codec to use for audio. The bitrate range for
AACLC is 32Kbps – 384Kbps (though staying above
64Kbps is recommended for best results). The
bitrate range for AACHE and AACHE V2 is 32Kbps –
64Kbps
