Software Solutions for Lecture Capture

Mediasite and TechSmith Relay are no longer avialable at UWGB. This document summarizes how to us CaptureSpace Lite or OBS studio as a work-around lecture capture recorder.

While fine as a review resource or for future reference by the instructor, full-class lecture capture is not a recommended practice for instructional purposes. Shorter (less than 10-15 minutes), content-specific, videos tend to work better in an online context. 

NOTE: OBS Studio is not directly supported on campus. Technical support for OBS Studio is available from their forums at https://obsproject.com/forum/

CaptureSpace Lite

Instructors may wish to record specific sections of their lectures using CaptureSpace Lite. Repurposing face-to-face lecture recordings for online courses is not recommended. More information about using CaptureSpace Lite is available here: Kaltura CaptureSpace Lite

Installing CaptureSpace Lite

  1. Navigate to https://media.uwgb.edu/
  2. Log in (in the upper right)
  3. Click Add New and select Recording
  4. Click the option to download CaptureSpace for your platform and follow the prompts to install the software

Using CaptureSpace to Record to a Flash Drive or M:/ Drive

  1. Plug a flash drive into the computer you would like to record (skip this step if using your M:/ drive)
  2. Launch the Kaltura CaptureSpace Recorder
  3. Click Settings
  4. Next to Local Media Files Storage click Browse
  5. Use the file browser to select your flash drive (usually an F:/ or G:/ drive or similar) and click OK
  6. IMPORTANT: Be sure to click SAVE in the lower right
  7. Return to the Record tab -- NOTE: It is recommended that you make a test recording to ensure that the video file is saved to your device
  8. Create your recording as normal using CaptureSpace Lite, but, when finished click Done, preview your video, click Done, and click SAVE instead of upload.
IMPORTANT NOTE: Once you've saved this setting (step 5-6), you MUST have your flash drive plugged in to launch CaptureSpace Lite on the same computer or you will receive an error which will prevent you from opening the desktop recorder.

OBS Studio

Instructors may wish to record specific sections of their lectures using OBS Studio. Repurposing face-to-face lecture recordings for online courses is not recommended.

Installing OBS Studio

OBS Studio can be installed from the X:/ Drive which should map automatically and be called "Apps" on a campus computer. NOTE: You will probably need administrator permissions from the helpdesk to install the software. The OBS installer is available in X:\Lecture Capture\OBS-Studio-VERSION-Full-Isntaller.exe
OBS Studio can also be installed from https://obsproject.com/

OBS Configuration/Layout Settings

Settings

  1. Open OBS and go to File > Settings (or click "Settings" under "Controls")
  2. Under Output set the following:
    • Output Mode: Simple
    • Video Bitrate: 1250
    • Encoder: Software (x264)
    • Audio Bitrate: 96
    • Enable Advanced Encoder Settings: UNCHECKED
    • Recording Path: Click Browse and navigate to a flash drive or suitable network share (M-Drives may fill up too quickly and are not recommended)
    • Generate File Name without space: UNCHECKED
    • Recording Quality: High Quality, Medium File Size
    • Recording Format: flv
    • Encoder: Hardware (QSV)
    • Custom Muxer Settings: BLANK
    • Enable Replay Buffer: UNCHECKED
  3. Under Video, ensure that the "Base (Canvas) Resolution" is either 1920x1080, 1280×720, or 1024×576 and that the "Output (Scaled) Resolution" matches it. The smaller video sizes are generally recommended.
  4. Click OK

Layout

  1. Under "Sources" click the plus sign and choose "Display Capture." Select the display under the "Display" dropdown (if applicable) and click OK. Note: You will probably see the "infinite screens" effect if you select the display you are currently using.
  2. Under "Sources" click the plus sign and choose "Audio Input Capture." Select your microphone (if applicable). By default, the software will also record the "Desktop Audio"
  3. Most people do not use "Scenes" (apart from the default) or Scene Transitions.
  4. If you are capturing a webcam as well, click the plus under "Sources" again and select "Video Capture Device" use the preview and, in most cases, the default settings to ensure that it's set up properly. Once you've added the webcam source, you may need to use the up and down arrows under "Sources" to ensure it appears on top of the display.
  5. Repeat step 1 and/or 5 to add additional displays or sources (such as additional web cams) if any.
  6. You may wish to alter the layout of the inputs. Do so by clicking and dragging and using the red circular handles on the corners of the regions. Pro tip: Use THIS IMAGE as an additional "Image" by clicking the plus sign under "Sources" and move it to the bottom using the arrows for a nicely branded UWGB background. 
  7. NOTE: If content is bigger than the canvas (likely if using a smaller resolution in Step 3 under "Settings"), just right click its preview and select Transform > Fit to Screen.

Recording

Once your setup is complete, click Start Recording under "Controls" Note: nothing pops up telling you it is recording, but the "Start Recording" button will change to "Stop Recording"
Most of the time, you'll want to just minimize OBS Studio while presenting. When done, open it from the task bar/system tray and click "Stop Recording"
Check that your video appears on your flash drive or in your alternative designated location.

Uploading Your Video

When you return to your office, you can upload your video to Kaltura using the steps to Upload Existing Media from Computer to Kaltura and selecting the video from your flash drive as the media file

Adding Recordings to a D2L Course

Once Kaltura has successfully processed your videos, you can add them to your course as you can any other Kaltura content. Here are some options for adding Kaltura content to D2L.
