Function Reference

vMix-compatible API

Shortcuts available on the vMix-compatible HTTP API (GET /api?Function=...). Input is a Scene’s flat number, name, or GUID. A raw Input is rejected because a Mixing Unit cannot take it. Unknown numbers are also rejected. 0 is the current Preview, -1 is the current Program. Omit Mix or use 0 for the selected Mixing Unit; 1 and up index Mixing Units in session order.

Function	Parameters	Action
Cut	Input, Mix	Cuts Preview to Program. If Input is set, that input is placed on Preview first
CutDirect	Input (required), Mix	Puts the input on Program. Preview does not change
Fade	Input, Mix, Duration	Same target as Cut, then Fade. Duration is milliseconds. If omitted, the Mixing Unit Fade preset is used, else 1000
PreviewInput	Input (required), Mix	Sets Preview to the input
ActiveInput	Input (required), Mix	Sets Program to the input. Preview does not change
