Network node
Video Link Send
Sends any image to other Grafit computers on the local network, under a name — live, with transparency. Every Grafit on the network sees it in Video Link Receive. Encoded on the Mac’s media engine (HEVC with alpha by default, H.264, or ProRes for studio quality); a frame reaches the other Mac in about a frame’s time on a cable. Nothing is encoded while nobody watches.
Inputs
| Port | Type | Default |
|---|---|---|
| ImageAny image output. Captured on the GPU after it is drawn, with its transparency, only while someone watches. | image | — |
| NameWhat other Grafits see in their list (Machine › Name). Unique per Grafit. | string | Video |
| EnableOff withdraws the stream; receivers keep their last frame (or go transparent) and find it again when it returns. | bool | true |
| QualityLow Latency — HEVC with alpha, 10–40 Mbit/s, fine on Wi-Fi. Compatible — H.264, no alpha. Studio — ProRes 422 Proxy (~40 Mbit/s, wired). Studio Alpha — ProRes 4444, exact alpha, hundreds of Mbit/s: gigabit cable, one stream. | int | — |
| ResolutionSource sends the image as it is; 50 % / 25 % shrink it; 720p / 1080p / 2160p set the height and keep the proportion. | int | 0 |
| FPSEvery frame sends each rendered frame; a number caps the rate (frames are skipped, never slowed). | int | 0 |
| Bitrate0 = Auto: starts at 20 Mbit/s, lowers itself when receivers lose packets, comes back on a clean network (2–40). Or a fixed Mbit/s, 1–400. ProRes ignores it. | float | 0 |
| ProtectOff — every Grafit on the network sees the stream. On — only machines with the same Link Key (Settings › Network) see it, and it is encrypted. No key on this Mac = nobody receives it (never falls back to open). | bool | false |
| MetadataAny value (number, text, colour, list, JSON) sent WITH each frame: the receiver’s Metadata output changes exactly when that frame is shown. Up to 16 KB per frame. | any | — |
| Audio DataOptional sound for the picture (any audio output). Sent as an Audio Link stream with the same name; Video Link Receive plays it in step with the frames (lip sync). | structure | — |
