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. 75
