Screen Recording (Windows Only)
This is an extremely useful feature in DW Spectrum for presentations. It is possible to record from several displays with
sound, select different quality, etc.
Screen can be recorded in the following formats:
Video: MPEG4 Part 2
Audio: Stereo (Lame Audio Codec)
Container: AVI
IMPORTANT. It is necessary to have a powerful processor and video adapter to do screen recording. See
recommended configuration in the installation guide.
Setting up Screen Recording
To set up Screen Recording:
1. Open Main Menu and choose Local Settings.
2. Go to the Screen Recording tab.
3. Configure Screen Recording parameters:
Temporary Folder – the folder that stores temporary files. FIles are stored during recording, then are copied to a
specified folder to be saved.
IMPORTANT. This folder should be accessible and writable.
Capture Mode: Fullscreen (if several monitors are installed the desired one should be chosen) or Application
Window (only DW Spectrum window will be recorded).
Disable Aero – select this option to enhance performance. If chosen, once Screen Recording is in progress,
Windows Aero will be turned off.
Capture Cursor – select this checkbox if a mouse cursor needs to be visible during recording.
Resolution – select screen resolution. The lower the resolution, the higher the performance.
Recording Quality – select Performance for best performance. Select Best for best quality.
Primary and External device – select sound devices to enable audio. Audio will get mixed from both devices. The
best practice is to select master from the sound card as primary and microphone as secondary. In this case, both
sounds from DW Spectrum (i.e. video clips) and microphone will be recorded simultaneously.
4. Click OK when done or Cancel to discard changes.
Note: If you want to record audio over the screen recording, set the Audio Input device from Local Settings ->
General tab
