@@ -126,12 +126,18 @@ Current native test coverage includes:
"outputFrameRate": "59.94",
"autoReload": true,
"maxTemporalHistoryFrames": 12,

```
`inputVideoFormat`/`inputFrameRate` select the DeckLink capture mode. `outputVideoFormat`/`outputFrameRate` select the playout mode. The shader stack runs at input resolution and the final rendered frame is scaled once into the configured output mode. Common examples include `720p`/`50`, `720p`/`59.94`, `1080i`/`50`, `1080i`/`59.94`, `1080p`/`25`, `1080p`/`50`, `1080p`/`59.94`, and `2160p`/`59.94`, depending on card support.
`audioEnabled` enables embedded stereo 48 kHz PCM pass-through. Audio is delayed to match the scheduled video preroll and the synchronized level/spectrum data is exposed to shaders.
Legacy `videoFormat` and `frameRate` keys are still accepted and apply to both input and output unless the explicit input/output keys are present.
