Smart Source Switch
Switches between multiple audio and video sources based on availability and priority
Component Configuration
| Option | Description | Required | Environment override |
|---|---|---|---|
id |
A unique identifier for the component instance |
✓ |
|
displayName |
The name shown in the Studio UI of this component |
✓ |
|
resolution |
All video will be normalised to this resolution (default: {"width":1920,"height":1080}) |
✗ |
|
frameRate |
All video will be normalised to this frame rate (default: {"frames":25,"seconds":1}) |
✗ |
|
sampleRate |
All audio will be normalised to this sample rate (default: 48000) |
✗ |
|
channelLayout |
All audio will be normalised to this channel layout (default: "stereo") |
✗ |
|
pixelFormat |
Pixel format all video is normalised to. 4:2:2 preserves chroma detail that 4:2:0 discards, and 10-bit preserves precision that 8-bit truncates; both cost a larger intermediate. Software only. (default: "yuv420p") |
✗ |
|
hardwareAcceleration |
Override the global hardware acceleration setting |
✗ |
|
resizeAlgorithm |
Resize filter used on NVIDIA hardware: cubic (default), linear (cheaper, softer) or lanczos (sharpest) (default: "cubic") |
✗ |
|
pipelineHints |
Quadra-only hardware pipeline hints (ignored on other hardware) |
✗ |
|
sources |
The priority order in which the sources will be chosen when available. Per source, the Video and Audio water marks (LWM/HWM) switch on the MQA-VIDEO / MQA-AUDIO score, 0-100 where 100 means no fault detected: a source below its low water mark is impaired and skipped, and restored at or above its high water mark. Empty = off. For audio on an A/B pair try 70 / 85 (healthy programme scores 92-95, a dead channel about 50). Scores come from an upstream Quality Monitoring component per source. Silence switching (Silence line) takes effect after that many ms of unbroken silence, 10 s by default once audio switching is on (default: []) |
✗ |
|
stayImpaired |
When enabled, sources that drop below a low water mark (video or audio) stay impaired until manually cleared by the operator (default: false) |
✗ |
|
qualityWarmupMs |
Time in milliseconds after a stream starts before quality scores affect switching decisions (default: 1000) |

Options with an environment override can be set when Studio starts, without
editing the workflow. |
