Recording an Audio Clip
You can use audio controls in the Media pane to record an audio master clip. This is an alternative way of recording a voice-over that gives you more flexibility than recording a voice-over for a sequence. To record an audio clip, you use the Media Pane in Asset mode.
This feature applies to Interplay Production assets only.
Adobe Flash Player
MediaCentral UX uses the recording function of the Adobe Flash Player to determine the input device used for the recording. The Flash Player automatically detects any default microphone or other audio recorder on your computer and uses that device unless you change it through the Flash Player settings. To access these settings, right-click anywhere in the Media viewer and select Settings. You can also change the input source from the Media Pane menu.
If you select a device different from the default system input device, then remove the device, you might need to manually change the Flash Player settings.
The first time you use the recording controls during a session, you see a message from the Flash Player asking for permission to let the MediaCentral UX server access your camera and microphone. Click Allow.
Interplay Administrator Settings
When you create a recording, the format is determined by two settings in the Interplay Administrator.
• Video Format setting on the Editing Settings tab of the Application Database Settings view.
This setting determines the frame rate. If the setting is Any, MediaCentral UX uses NTSC 29.97 as the default format. The following illustration shows the Video Format for the root folder set for PAL 25i.
• Audio - general settings on the Editing Settings tab of the Application Database Settings view
- Audio sample rate: Fixed at 48kHz
- Sample bit depth: Choice of 16 or 24-bit (16-bit is the default)
- Audio file format: Fixed as PCM.
The following illustration shows the bit depth set for 16.
These settings apply at the folder level.
