# Inputting and Outputting a Live Video Signal

If you uncomment a Live Video VTR keyword you can capture a live video signal or crash-record a clip using the pen to start and stop the clip input or output process.

On input, use the Live NTSC or PAL option to capture directly from a camera, VCR, or any other device that does not support remote control via RS-422. You can also feed a live video signal from satellite or any other broadcast source.

On output, use the Live Video option to output clips to a device that does not support remote control via RS-422.

To input a live video signal:

1. Enter the VTR Input module.
2. From the VTR Device box, select Live NTSC or Live PAL.

   The incoming live video signal appears in the preview window. The Start Mode box is unavailable. With Live Video capture, you must use Start On Pen mode. You can use Stop On Pen or Stop On Frames to end the capture.

   NoteWhen Stop On Pen is selected as the preferred capture stop mode, the out point and the duration timecode fields are updated to reflect the longest possible duration corresponding to the full capacity of a framestore. The capture stops either when you click anywhere on the screen or the timecode indicated is reached, meaning that the framestore is full.
3. Set input options. For example, enter the clip name and enable the video tracks and audio channels that you want to capture. See Inputting Clips From a VTR.
4. Make sure you are receiving the live video signal.
5. If you are capturing from a device that does not support remote control, press Play (allowing enough time to click Process in Smoke).
6. To begin capturing, click Process.

   After a moment, you are prompted to click anywhere to begin the output process.

7. Click anywhere on the screen.
8. To end capturing in Stop On Pen mode, click anywhere on the screen.

To output a live video signal:
