Memo :
When "VBR" is set, the [Bitrate] setting uses
0
30 fps as a reference value.
When the frame rate is low, the actual bitrate
distributed may drop.
Example: When the frame rate is 15 fps and the
I-frame interval is 15 frames, specifying the
bitrate as 8192 kbps gives a maximum bitrate of
about 4000 kbps. (When the frame rate is below
30 fps, the extent to which the maximum bitrate
drops is dependent on the frame rate and the
I-frame interval.)
9 I Frame Interval (when "H.264 Baseline" or
"H.264 High" is selected)
Encoding starts from the I-frame. Shortening the
interval stabilizes the picture quality even when
there are rapid changes in the video image.
However, the picture quality for images with little
change will deteriorate.
[Set values: 5, 10, 15, R30, 60, 90, 120] Frame
9 Quality (when "JPEG" is selected)
Selects the JPEG picture quality (scalable rate
control method) and picture quality level.
AFS:
0
Encoding is performed such that the target file
size is the average size of multiple JPEG
images.
VFS:
0
The quantization table during JPEG encoding
will be maintained and the file size will increase
or decrease according to the input signals.
When recording JPEG data to a recorder with a
limited storage capacity, the maximum
recording time may vary as the file size
fluctuates under this setting.
[Set values: RAFS, VFS]
[Picture quality level: Level 1 to RLevel 7]
Memo :
The target file size varies with the frame size and
0
picture quality level settings. The reference
value per frame is displayed to the right of the
picture quality setting pull-down menu.
When "Multi-Encode" is selected in [Encode]
Each of the three channels of the encoder can be
set to H.264 High, H.264 Baseline or JPEG, and a
different frame size can also be specified.
However, only one channel is available for H.264
Baseline, and therefore it cannot be set for multiple
encoders at the same time.
.
Encoder No.1, Encoder No.2 and
Encoder No.3
Select either JPEG, H.264 Baseline, or H.264
High.
When Encoder No.3 is set to "OFF", the
Encoder No.3 item will be disabled.
[Encoder No.1 settings: JPEG, H.264 Baseline,
RH.264 High]
[Encoder No.2 settings: RJPEG, H.264 Baseline,
H.264 High]
[Encoder No.3 settings: JPEG, H.264 Baseline,
H.264 High, ROFF]
