Selecting audio source

QTM can record the audio from DirectShow devices together with a DirectShow video source. This can for example be the microphone on the computer or audio on the Intensity Pro card. The available audio sources is listed in the menu, however for DV cameras this option is not available because the audio is already included in the video.

To set the audio source for a video source follow these instructions>

1. Start a new measurement and open a 2D view window.

2. Right-click on the Video view that you want to set the audio source for and click on Connect to audio source in the menu.

   

3. Then select the audio source you want from the list. QTM will remember the audio source as long as the video source is available on the computer.
