Media

Images, video, Lottie and audio: sourcing, playback and transport.

Live cameras and sources: NDI, SRT, RTMP, SDI.

A Feed shows one of this machine's live inputs — an NDI source, an SRT stream, an RTMP stream, or a DeckLink SDI capture — as a picture on the page, the way a vMix input sits in a layer. Inputs are set up once per machine in Settings › Inputs; a Feed names the one it shows.

SettingMeaning
InputThe input it shows. Stored as the node's src, which also accepts an input's name (any case) or number (list order), like vMix's input key, title or number.
By nameThe same value as text. Bind it to a data path to cut between cameras from data.
+ NDI / SRT / RTMP / SDICreate a new input and point this Feed at it; Settings › Inputs opens to finish it.
FitCover, contain (the default), stretch or none, as for video.
No signalWhat airs when the input drops: Hold its last picture (default), Black, or Clear to show what is behind.

A Feed has no plate colour of its own: an NDI source with alpha keys over whatever sits behind it. In the editor a Feed that has no picture shows what it is doing — connecting, waiting for the sender, no signal, no such input. The output never shows those cards.
