Video Codec Tab - Sony BRC-X401 Operating Instructions Manual

Video codec tab

Use this tab to perform settings related to video
codec. Up to 5 users can simultaneously view
images of a single camera. However, when
multiple users view images, the images may be
corrupted depending on the codec setting.
Image 1, Image 2, Image 3
Up to three video codec modes can be set.
Configure the following setting for each image
mode.
Codec
Select [H.264], [H.265], or [Off]. However, you cannot
select [Off] for [Image 1].
Note
The following symptoms may occur depending on
combinations of various settings such as the Size,
Frame rate, Bit rate, etc. for Image 1, 2, and 3.
• Image delay increases.
• A frame skip occurs when playing an image.
• Audio is interrupted.
• Camera response to commands is slow.
• Camera response to operation from the remote
controller is slow.
• Displaying the monitor screen and configuring
camera settings are slow.
In this case, adjust by lowering the parameter values
of the Size, Frame rate, and Bit rate, or changing
other setting parameter values.
Size
Select the image size transmitted from the camera.
Selectable image size is changed depending on the
video output format which is selected by the
SYSTEM SELECT switch on the back of the camera or
format setting of video output.
Frame rate
Set the frame rate of the image.
"fps" is a unit indicating the number of frames
transmitted per second.
Selectable frame rate is changed depending on the
video output format which is selected by the
SYSTEM SELECT switch on the back of the camera or
format setting of video output.
I-picture mode
Select from [Time] or [Frame] to specify the insertion
interval of H.264/H.265 I-picture.
[Time]: Set I-picture insertion interval by time.
[Frame]: Set I-picture insertion interval by number
of frames.
I-picture interval
Set the I-picture insertion interval in seconds.
I-picture ratio
Set the insertion interval of H.264/H.265 I-picture by
number of frames.
H264 profile
Select the profile for H.264 video codec from [high],
[main], or [baseline]. The video compression
efficiency is high in the sequence of [high], [main],
and [baseline]. Select the suitable profile for your
program.
Bit rate compression mode
Select [CBR] or [VBR].
When you want to maintain the constant bit rate,
select [CBR] and to stabilize the image quality, select
[VBR].
Note
The frame rate or bit rate that is actually transmitted
may be different from the setting value depending
on image size, scene, and network environment.
Bit rate
When [Bit rate compression mode] is set to [CBR],
you can set the bit rate for each line of image
distribution. When the bit rate is set to a higher
value, higher-quality images can be distributed.
H264 quality
Set the image quality when [Bit rate compression
mode] is set to [VBR] and [Codec] is set to [H.264].
Select a value from [1] to [10].
Selecting [10] provides the maximum image quality.
H265 quality
Set the image quality when [Bit rate compression
mode] is set to [VBR] and [Codec] is set to [H.265].
Select a value from [1] to [10].
Selecting [10] provides the maximum image quality.
