See “Buttons common to every menu” on page 21.
Video codec Tab
Use this tab to set the items for the video codec.
High framerate mode
When the setting is set to On , set the maximum frame
rate to 60 fps (NTSC) or 50 fps (PAL).
When the setting is set to
Off , the maximum frame rate
is 30 fps (NTSC) or 25 fps (PAL).
When the high framerate mode is changed, the camera
returns to the home position.
Notes
• When the setting is set to On , Image 2 may not be
available, and Image 3 is not available.
• When the high framerate mode setting is changed,
settings for Image 1, Image 2, and Image 3 are
returned to the default settings.
Image 1, Image 2 and Image 3
Up to three image codec modes can be set. Configure the
following setting for each image mode.
Image codec
Select H.264 , JPEG or Off . Note that Image 1 cannot be
set to Off .
Note
The selectable size of images and frame rate for Image
2 and Image 3 may be limited, depending on the setting
of codec type, image size, frame rate, and image quality
for Image 1.
• The total of frame rate for Image 1, Image 2 and Image
3 should not exceed 60 fps.
• If you set the bitrate of Image 1 to 32000 kbps, set
Image 2 and Image 3 to Off.
• If you set the bitrate of Image 1 to 16000 kbps or
faster, set the bitrate of Image 2 and Image 3 below
4000 kbps.
If you set a value exceeding the standard, the following
symptoms may occur.
• The image delays more than usual.
• The frame is skipped when playing an image.
• The voice is broken.
• The response of the camera to commands delays.
Image size
You can select the size of images sent from the camera.
Notes
• Some parts of the screen may not be displayed
depending on the image size.
• If the image size is 720 × 574 or 720 × 480, the full
image is displayed but not in the 1:1 pixel aspect ratio.
Frame rate
Set the frame rate of the image.
“fps” is a unit indicating the number of frames
transmitted per second.
The frame rate of JPEG image can be changed by the
setting of
Image quality .
I-picture interval
Set the I-picture insertion interval in seconds.
H.264 profile
Set the profile setting for H.264 video codec to high ,
main or baseline . The video compression efficiency is
high , main and baseline in sequence. The specified
profile may not be available depending on the program
you use. Select the profile which is suitable for your
program.
Bit rate compression mode
Select CBR , VBR or Adaptive rate control .
If you want to keep the bit rate fixed, select CBR . If you
want to keep the image quality fixed, select VBR .
If you select Adaptive rate control , the bit rate is
automatically optimized for unstable network
connections or wireless networks with a lot of
interference.
Notes
• The frame rate or bit rate that is actually transmitted
may be different from the set values depending on
image size, scene, network environment.
• The Adaptive rate control cannot operate when the
Plug-in free viewer is being used.
• If you want to use the Adaptive rate control , set the
connection method in the live viewer to Unicast . If
you set TCP as a connection method, the adaptive rate
control will be disabled. For details, refer to
“Switching Transmission Mode” in “Operating the
Camera” on page 18.
Bit rate
When you set Image codec to H.264 and set Bit rate
compression mode to CBR , the bit rate of the image
transmission for a line can be set.
When the bit rate is set to a high level, a high image
quality can be enjoyed.
