## Video And Preview
Video input and output are optional edges. DeckLink is the current concrete backend. Configured video modes are represented in `src/video/core` and translated to DeckLink display modes only inside `src/video/decklink`.
Video input and output are optional edges. `videoInputBackend` and `videoOutputBackend` select the concrete backend through the app-side backend factory. DeckLink is the current concrete backend, and `none` disables that edge. Configured video modes are represented in `src/video/core` and translated to DeckLink display modes only inside `src/video/decklink`.
The input edge writes CPU frames into `InputFrameMailbox`. The current DeckLink backend captures BGRA8 directly where possible, or raw UYVY8 for render-thread GPU decode. The input edge does not call GL, render, preview, screenshot, shader, or output scheduling code.
