RTMP Target (Multi scaler)

Property	Type	Access	Description
`ShowAdvancedOptions`	`bool`	`get/set`	Reveals advanced/expert properties — backup addresses, H.264 profile, GOP size, and NVENC tuning JSON for each destination. Off by default.
`AutoStart`	`bool`	`get/set`	When On, all enabled destinations connect automatically when the project loads. Useful for unattended multistreaming setups.
`ConnectionStatus`	`ConnectionStatus`	`get/set`	Aggregate connection status across all enabled destinations (read-only). Use per-destination `DestNConnectionStatus` for fine-grained checks.
`StartCommand`	`Command`	`get`	Connects all enabled destinations and begins streaming.
`StopCommand`	`Command`	`get`	Stops streaming and disconnects all destinations.
`ReconnectCommand`	`Command`	`get`	Schedules an immediate reconnect of every destination without tearing down the encoder. Use when a CDN has had a hiccup but the local pipeline is fine.
`AacBitRate`	`AacBitRate`	`get/set`	AAC audio bitrate used by every destination (audio is encoded once and muxed to all destinations). Typical: 128 kbit/s for stereo broadcast.
`ReconnectInterval`	`ReconnectInterval`	`get/set`	How long to wait before retrying a failed destination. Each destination reconnects independently — a single bad CDN doesn't slow the others down.
`MaxOutputQueueSize`	`int`	`get/set`	Maximum number of encoded packets queued before frames are dropped. [min=50, max=500, default=200]. Larger queues mask brief network slowdowns at the cost of added latency.
`Dest1Enabled`	`bool`	`get/set`	When On, destination 1 streams. Disable if you only need destinations 2–4.
`Dest1ServerAddress`	`string`	`get/set`	Primary RTMP/RTMPS server URL for destination 1 (e.g. `rtmp://live.twitch.tv/app/STREAM_KEY`). Supports macros: `@@RandomId()`, `@@SharedRandomId()`, `@@HostName()`. Treat as sensitive — stream keys live in this URL.
`Dest1BackupAddress`	`string`	`get/set`	Optional fallback URL for destination 1, used after the primary address fails. Useful for redundant CDN ingest endpoints.
`Dest1Resolution`	`ImageOutputResolution`	`get/set`	Output resolution for destination 1. `Unchanged` keeps the scene resolution; the others rescale (1080p / 720p / 540p / 360p) so each destination can receive a different rung of an ABR ladder.
`Dest1Bitrate`	`OutputVideoBitrate`	`get/set`	Target video bitrate for destination 1. Match this to what the destination CDN expects for the chosen resolution.
`Dest1Codec`	`VideoCodecType`	`get/set`	Video codec for destination 1. `H264_NVENC` uses GPU hardware encoding (recommended); `H264` uses the CPU software encoder.
`Dest1H264Profile`	`H264Profile`	`get/set`	H.264 profile for destination 1. `main` is widely compatible; `high` gives slightly better compression at the cost of older-decoder support.
`Dest1GopSize`	`VideoCompressionGopSize`	`get/set`	GOP (keyframe spacing) for destination 1. Typical: 1x or 2x framerate.
`Dest1NvencOptions`	`string`	`get/set`	NVENC encoder parameters for destination 1 as a JSON object. Only applies when the codec is `H264_NVENC`. Defaults are tuned for low-latency live.
`Dest1ConnectionStatus`	`ConnectionStatus`	`get`	Connection status for destination 1 (read-only). Useful in scripts to raise an alert when one CDN drops while others stay up.
`Dest1ActiveUrl`	`string`	`get`	The fully resolved URL for destination 1, with all macros expanded (read-only, debug).
`Dest1SendQueueDepth`	`int`	`get`	Debug (read-only): packets queued for destination 1's async sender, waiting to be written. Rises first when this destination can't keep up.
`Dest1DroppedPackets`	`long`	`get`	Debug (read-only): total packets dropped for destination 1 because its send queue was full. Stays 0 when healthy.
`Dest1ReconnectAttempts`	`int`	`get`	Debug (read-only): consecutive reconnect attempts in flight for destination 1. Non-zero means it is reconnecting/flapping.
`Dest2Enabled`	`bool`	`get/set`	When On, destination 2 streams.
`Dest2ServerAddress`	`string`	`get/set`	Primary RTMP/RTMPS server URL for destination 2. Supports macros (`@@RandomId()`, `@@SharedRandomId()`, `@@HostName()`). Treat as sensitive.
`Dest2BackupAddress`	`string`	`get/set`	Optional fallback URL for destination 2.
`Dest2Resolution`	`ImageOutputResolution`	`get/set`	Output resolution for destination 2.
`Dest2Bitrate`	`OutputVideoBitrate`	`get/set`	Target video bitrate for destination 2.

`Dest2GopSize`	`VideoCompressionGopSize`	`get/set`	GOP (keyframe spacing) for destination 2.
`Dest2NvencOptions`	`string`	`get/set`	NVENC encoder parameters for destination 2 as JSON.

`Dest2ReconnectAttempts`	`int`	`get`	Debug (read-only): consecutive reconnect attempts in flight for destination 2. Non-zero means it is reconnecting/flapping.
`Dest3Enabled`	`bool`	`get/set`	When On, destination 3 streams.
`Dest3ServerAddress`	`string`	`get/set`	Primary RTMP/RTMPS server URL for destination 3. Supports macros. Treat as sensitive.
