MAIN CRASH [type]

Crashes the service. [type] can either be omitted or be one of:

MAIN: Crash the service (same as when omitted).
RECORD: Crash the recording thread.

OUTPUT

One output target can be initialized during startup. During execution more than one output can be enabled. For instance you can have VideoOut A and Coder enabled. Please refer to Channel Recorder Configuration to initialize an output during startup.

Command	Description
`OUTPUT GET`	Lists the active targets.
`OUTPUT LIST`	Lists available targets.
`OUTPUT START` [target]	Starts an output handler for the specified [target]. Several output handlers can be started in parallel, but only one is allowed for each target. Valid targets are: `VideoOut`: This target requires one additional parameter: `[connector]`. The `[connector]` parameter specifies the video output connector of the Matrox board. Example: `OUTPUT START VideoOut A` `Coder`: This target requires three additional parameters that can be configured via `CONFIG SET SHMOUT` commands. Example: `OUTPUT START Coder SHMCoder1 localhost 12345`
`OUTPUT STOP` [target]	Stops the output handler for the specified target.

RECORD

Crash Recording / One-time Scheduling

These are specific commands used only for crash and one-time scheduling of recording. These command are available from version 1.0. For scheduling, it is recommended to use RECORD SET introduced from version 1.1.

Command	Description
`RECORD CLIP` [clip name]	Sets the clip name and initializes the recorder. This command does not start recording (see`RECORD START`).
`RECORD START` [duration] [start time] [end mode]	Starts or continues recording. The `[duration]`, `[start time]`, `and [end mode]` parameters are optional. However, the parameters are interdependent as follows: If the parameter `[start time]` is provided, `[duration]` is also required. If the parameter `[end mode]` is provided, `[duration]` is also required. The format for both is Timecode (see Data Types). `[duration]` and `[start time]` can be zero timecode, which will then be ignored. `[end mode]` can either be `STOP`, which finalizes and closes the clip, or `PAUSE` (default behavior), where the clip stays open and can be used for further recording.
`RECORD PAUSE`	Pauses recording.
`RECORD STOP` [end time]	Stops recording and flushes the recorder. A new clip needs to be set afterwards (see `RECORD CLIP` ). The end time is optional and specifies the timecode when the recording should end.

Example: Crash recording:

RECORD CLIP Crash.mxf
RECORD START
RECORD STOP

One-time scheduling recording:

RECORD CLIP Crash.mxf
RECORD START 600 15:00:00:00

Loop Recording

These are specific commands used only for loop recording. It allows setup, start or stop loop recording. These are introduced from version 1.1.

Command

Description

RECORD LOOP [key=value] ... [key=value] [operation]

Starts, stops or configures the settings for loop recording. Any number of properties can be applied in the form of key-value-pairs. If no property is supplied, and the entry does not yet exist, it is added with the default values. Available keys are:

PREFIX: Prefixes to the filename. It will be appended with the timestamp of the start time.
POSTFIX: Postfixes to the filename. Will be appended after the timestamp.
LENGTH: Determines the length of the loop in frames or timecode. At least this amount of frames will reside on the disk. The minimum length value is 00:02:00:00 or the equivalent number of fields / frames.
CHUNK: Sets the size of one chunk in frames or timecode. The chunk size influences the loop length. The minimum chunk value is 00:00:30:00 or the equivalent number of fields / frames.
DISKSIZE: Sets the size of the loop is defined by the size of the clips on the disk. The oldest clips are deleted until the disk size drops below the specified value.
DISKFREE: Sets the size of the loop is defined by the space left on the disk. If it drops below the value, the oldest clips are deleted until at least the specified amount is free again.

[operation] can be START or STOP. When no [operation] is specified then only the settings are set for the specified key-value-pairs. It is possible to specify [key=value] [operation] at the same time but only when [operation] is START.

Example: RECORD LOOP LENGTH=00:05:00:00 CHUNK=00:00:30:00 PREFIX=Loopy START
RECORD LOOP STOP

Scheduled Recording

These are specific commands used only for scheduled recording. It allows setup, start or stop scheduled recording.

Command	Description
`RECORD SET` [name] [key=value] ... [key=value]	Adds a new clip to the timeline, or changes a property of an entry defined by `[name]`. Any number of properties can be applied in the form of key-value-pairs. If no property is supplied, and the entry does not yet exist, it is added with the default values. Available keys are: `FILE_EXTENSION`: Enables or disables automatically adding a file extension to the file name. If this feature is turned off, the client application has full control over the file name. `CONTAINER`: Sets the container type of the recorded file. With the container type, a default codec is also set. By setting the container type, a valid recording can be started. `CODEC`: Sets the codec type of the recorded file. By setting the codec type, default values for bitrate and audio will also be set. `BITRATE`: Sets the bitrate for the video encoding. The value can either be applied as bits per second or as Megabits per second. Not all codecs allow changes to the bitrate. In such cases, `BITRATE` will be ignored. `IN`: Sets the default value for the recording in point. The value must be in timecode format: `00:00:00:00`. `OUT`: Sets the default value for the recording out point. The value must be in timecode format: `00:00:00:00`. `DURATION`: Sets the default value for the recording duration. The value can be in frames or in timecode format: `00:00:00:00`. `STARTTC`: Sets the default value for the starting timecode. The value must be in timecode format: `00:00:00:00`. `AUDIOCHANNELS`: Sets the number of audio channels to record. How many channels are actually recorded depends on the codec and the input signal. `DISKACCESSSIZE`: Sets the size of data blocks written to the disk in byte. Postfixes like KiB, Kb, k, etc., are allowed, but must not be separated from the value with a blank space. The default value is 4MiB (4194304 bytes). The minimum value is `32KiB` (32768 bytes). KiB and k multiplies the value by 1024. kb multiplies the value by 1000. The same works with m for mega and g for giga. `VBR`: Sets whether the recorded file, when the format supports it, should be in VBR (Variable Bit Rate). `TDIR` Sets the default behavior of TDIR (Time Delayed Instant Replay). `TDIRINTERVAL`: Sets the interval of file header updates in TDIR (Time Delayed Instant Replay) recordings. The value is in seconds and fractions of seconds, meaning both 11.1 and 11.2 are considered valid values. Minimum allowed value is `10s`, which is interpreted by Channel Recorder as every frame. The maximum value is `60.0s`. `UPDATEMT`: Updates the modification time of the recorded clip regardless of TDIR value. The initial value is `On`. `STOPATEND`: Sets the default behavior at the end of the recording. For more information regarding these settings possible values and default values check the section `CONFIG SET` below.
`RECORD REMOVE` [name] ... [name]	Removes the entry`[name]`. Multiple`[name]`arguments can be provided.
`RECORD GET` [name] \| [key] ... [name] \| [key]	Lists all entries or shows the properties of an entry. If no parameter is applied, a list of all scheduled clips is returned. Any number of`[name]`and`[key]`can be applied. The values of all keys will be returned for all values. If no`[key]`is provided, all values of the applied keys will be returned and vice versa. This means that if you call `RECORD GET` with clip names only, the command returns all properties of these clips. When called with properties only, it will return this property for all clips. A special`[key]`is`TIMELINE`, which returns all entries in the timeline.

Common Record Commands

Some of these commands are only used for loop and crash recording, while others are used for all three modes.

Note: When container is XDCAMMXF the default codec will be XDCam which is HD422. The default bitrate for XDCam, XDCamEX and XDCamHD are `50`, `35` and `35` respectively. XDCamEX will output 1920x1080 clip at 35 Mbps and XDCamHD will output 1440x1080 clip at 35 Mbps (VBR) or 25 Mbps (CBR) depending on the bitrate chosen. Refer to the Supported Codecs for further details.
`BITRATE` [rate]	Sets the bitrate for the video encoding. The value can either be applied as bits per second or as Megabits per second. Not all codecs allow changes to the bitrate. In such cases, `BITRATE` will be ignored.

The minimum value is `32 KiB` (32768 bytes). `KiB` and `k` multiplies the value by `1024.` `kb` multiplies the value by `1000`. The same works with `m` for mega and `g` for giga. Example: `CONFIG SET DISKACCESSSIZE 1024KiB`
`VBR` [bool]	Activates variable bit rates for codecs which support it (currently XAVC only). The default setting is `Off`.
`TDIR` [bool]	Sets the default behavior of TDIR (Time Delayed Instant Replay). The default setting is `On`.
`TDIRINTERVAL` [time]	Sets the interval of file header updates in TDIR recordings. The value is in seconds and fractions of seconds, meaning both `0.1` and `1.0` are considered valid values. Minimum allowed value is `0.001`, which is interpreted by Channel Recorder as every frame. A typical value would be `10.0`, the default value is `3.0`. Warning: To secure proper operation with Viz Engine, this value must not exceed `10.0`.
`UPDATEMT` [bool]	Updates the modification time of the recorded clip regardless of TDIR value. The initial value is `On`.
`STOPATEND` [bool]	Sets the default behavior at the end of the recording.
