Setting the Video Codec for Streaming
Set the video codec using [Stream] > [Video Stream] in the web menu.
[Video Stream 1], [Video Stream 2], [Video Stream 3]
You can set up to three image codec modes. Configure the following settings separately for each image mode.
[Video Stream 3] is used for the Web App camera image panel display.
Note
- When [Stream] > [Stream Setting] > [Setting] is set to [RTMP], [SRT-Caller], or [SRT-Listener], some of the [Video Stream 1], [Video Stream 2], and [Video Stream 3] settings ([Codec], [Size], [Frame Rate], [Bit Rate Compression Mode]) have default values.
[Codec 1], [Codec 2], [Codec 3]
Select [H.264], [H.265], or [Off]. Note that [Codec 1] cannot be set to [Off]. Also, [Codec 3] is set to [JPEG] (fixed).
Note
- The following symptoms may occur depending on the combination of various settings, such as the picture size, frame rate, and bit rate of [Codec 1], [Codec 2], and [Codec 3].
- Increased video latency.
- Frame skipping during video playback.
- Intermittent audio.
- Slow camera response to various commands.
- Slow camera response to operations from a remote controller.
- Slow monitor screen display and configuration operations.
If you experience these symptoms, reduce the values of the picture size, frame rate, and bit rate parameters, or change the values of other setup parameters to resolve the issue.
- When [Stream] > [Stream Setting] > [Setting] is set to [RTMP], [SRT-Caller], or [SRT-Listener], [Codec 1] is set to [H.264] (fixed). [Codec 2] is set to [Off] (fixed).
- When the picture size or system frequency of the HDMI output is changed, [Codec 2] is set to [Off].
[Size 1], [Size 2], [Size 3]
Selects the picture size to stream from the camera.
The available picture size options will vary depending on the picture size of the HDMI output.
Note
- When the picture size or system frequency of the HDMI output is changed, the maximum picture size will be selected.
[Frame Rate 1], [Frame Rate 2], [Frame Rate 3]
Sets the frame rate of the image.
“fps” units indicate the number of frames streamed per second.
The available frame rate options will vary depending on the picture size of the HDMI output.
Note
- When the picture size or system frequency of the HDMI output is changed, the maximum frame rate will be selected.
[I-Picture Mode 1], [I-Picture Mode 2]
Sets the method for specifying the I-picture insertion interval for H.264 and H.265 to [Time] or [Frame].
Cannot be set for [Codec 3].
[Time]: Sets the I-picture insertion interval as a time.
[Frame]: Sets the I-picture insertion interval as a number of frames.
[I-Picture Interval 1], [I-Picture Interval 2]
Sets the I-picture insertion interval in units of seconds. Sets a value in the range 1 second to 5 seconds. The default value is 1 second.
Cannot be set for [Codec 3].
[I-Picture Ratio 1], [I-Picture Ratio 2]
Sets the I-picture insertion interval for H.264 and H.265 as a number of frames in the range 15 to 300. The default value is 300 frames.
Cannot be set for [Codec 3].
[Profile 1], [Profile 2]
Sets the H.264 or H.265 image codec profile.
[H.264]: Select [high], [main], or [baseline] profile.
[H.265]: Select [main] or [main10] profile. When two video codecs are enabled, only the [main] profile selection option is available.
Image compression efficiency increases in the order of [high], [main], and [baseline]. Select a profile supported by your system.
When [H.265] is set to [main10], operation is in [main10] when the HDMI output is YCrCb or in [main] when the HDMI output is RGB.
Cannot be set for [Codec 3].
[Bit Rate Compression Mode 1], [Bit Rate Compression Mode 2]
Select [CBR] or [VBR].
To maintain a constant bit rate, select [CBR]. To maintain image quality, select [VBR].
Cannot be set for [Codec 3].
Note
- The frame rate and bit rate actually streamed may differ from the set values, depending on the picture size, shooting scene, network environment, and other factors.
- When [Stream] > [Stream Setting] > [Setting] is set to [RTMP], [SRT-Caller], or [SRT-Listener], [Bit Rate Compression Mode 1] is set to [CBR] (fixed).
[Bit Rate 1], [Bit Rate 2]
You can set the bit rate per video stream when [Bit Rate Compression Mode] is set to [CBR]. Setting a high bit rate allows you to stream high image quality video.
Cannot be set for [Codec 3].
[Quality 1], [Quality 2], [Quality 3]
Sets the image quality in the range 1 to 10. A value of 10 sets the highest image quality. The default value is 6.
For [Quality 1] and [Quality 2], you can set H.264 image quality by setting [Bit Rate Compression Mode] to [VBR] and [Codec] to [H.264]. You can set H.265 image quality by setting [Bit Rate Compression Mode] to [VBR] and [Codec] to [H.265].
