10 Main Menu Settings Select Settings 10

11 AcuStudio Menu AcuStudio General Recording: Click on AcuStudio Settings and select General tab: Limit Gain: When checked, the amplification of the audio will be limited. This will prevent the unwanted background noise to be amplified and sudden loudness when the speaker speaks again. However in the case of where many speakers will be using the system, as in a lecture theatre, the gain should not be limited. For example, if a lecturer speaks very loudly and holds the microphone close to his mouth, the amplification is reduced. The next lecturer speaks softly with the microphone further from his mouth; he will be too soft if the gain limit is enabled. Uncheck Limit Gain when AcuStudio is set in lecture hall and many lecturers are expected to use it. Check Limit Gain if we are expecting single speaker in a noisy environment. Enable OCR on secondary video: If checked, AcuStudio will do an OCR on the secondary video device. Note: OCR is done on a best effort basis. The main purpose is for better indexing and searching for related content Watermark: If checked, you can embed an image (e.g. Company logo) in the videos. Browse to the required image file; choose the position, % width as compared to the video and opacity. 11

12 AcuStudio Interactive: Select Settings under AcuStudio Interactive. Select Interactive tab. Add devices on motion detect: When checked, the video will appear once AcuStudio detects movements. Example: If you set to record 3 devices, the initial recording will capture the camera s video. The visualizer and document will be captured only when AcuStudio detects change in the image of the visualizer camera and/or document screen. 12

13 Select Start from AcuStudio. AV Wizard Select the number of devices that will be recorded. AcuStudio supports up to maximum of 3 devices. These devices can be video and/ or monitor screen. 13

14 Select the sources for audio and video. Note that audio can be configured to record audio from both video playback (Movie, YouTube etc) and microphone. If you have selected to record mic + speaker, it is advisable not to place your microphone too near the speaker. If your microphone picks up audio from the speakers, the sound quality will be affected (Echo effect). 14

15 For each device, you can select the capture size and color space. Some hardware support certain fps based on certain color space e.g. 30 fps is supported on MJPG for 1280X720. You may need to fix the setting based on your hardware specifications. For document settings, you can also choose enable or disable motion detect if the device is connected to a document camera. If motion detect is selected and motion detected, AcuStudio will move the channel to big video view. You can choose the standard template for HD or FHD or customize the profile to your preference. Please note the warning below for certain older devices cannot playback high quality video. Test Profile As mentioned above, understanding the settings of webcam and the relationship between color space, fps and source size can be perplexing. AcuStudio can help you do that job. By clicking on the Test Profile button, the system will run through a series of test on your available hardware color space, fps, source size and CPU. If your profile selection is higher than your hardware capabilities, AcuStudio will automatically configure a more suitable profile for you. If your profile selection is lower than your hardware capabilities, AcuStudio will use your desired profile and no changes will be made. Summary After choosing the AV profile, a summary of your selection is shown. If you are satisfied with your selections/settings, click Finish to exit the wizard, otherwise click Back to change your selections/settings. 15

If you have turned off Motion Detect on the presenter webcam, the video of the presenter will never take the big video channel. Document Camera motion detection will take priority over Slide/ Screen. Cool down period starts once no further motion is detected. Record Preview If you are recording 3 devices with high quality video settings, you may notice very high CPU utilization. This is perfectly normal. When CPU reaches 85% over 10 seconds during recording session, the recording preview fps will be reduced to conserve CPU. This will not affect final video production fps.
