# About VTR Emulation

You can use Smoke to emulate a VTR for both input and output in real time. When configured to emulate a VTR, Smoke can be controlled, using an RS-422 interface, by a third-party application or device allowing you to:

- Load a clip into the Output Clip menu, enable an emulator and then use another application or device capable of capturing from a VTR to capture the clip.
- Enable an emulator in the Input Clip menu and then use another application or device capable of outputting to a VTR to output clips to the Smoke workstation.

In all cases, you control the emulator from the application or device that treats Smoke as a VTR device.
