Software Solutions for Lecture Capture

Mediasite and TechSmith Relay are no longer avialable at UWGB. This document summarizes how to use 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

Kaltura Capture

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

Using Kaltura Capture

When Kaltura Capture finishes launching, the recording setup toolbar is displayed:

The icons in the recording setup toolbar, from left to right, are:

  • Start Recording - click the red record button to start a new recording.

  • Screen capture recording - click this icon to disable or enable screen capture for your recording. If you have more than one monitor, select which to record by clicking the caret (i.e. down arrow) next to the icon to open a preview window and input settings menu.

  • Webcam recording - click this icon to disable or enable the webcam for your recording. This will not appear if Capture does not detect your webcam. Click the caret next to the icon to view a preview of your webcam and select which camera device to record.

  • Microphone recording - click this icon to disable or enable the microphone for your recording. If you have more than one microphone device, click the caret next to the icon to select which device to record.

  • Manage - use this link to manage any recordings you have stored on your computer (e.g. delete, describe, upload, etc.). You can also change the recording resolution of your screen and camera and toggle system audio recording. You would want to record system audio in the event you were capturing other media or items with sound within your recording.

After starting a recording, a small recording panel appears in the bottom corner of your screen:

The icons on the Kaltura Capture recording panel from left to right are:

  • Stop recording (square icon) - click this when you're all done recording

  • Pause recording (double vertical lines icon) - useful when taking a break or to change recorded content (e.g. switch from PowerPoint to a YouTube clip). This icon turns into the resume recording icon when a recording is paused.

  • Cancel recording (X icon) - discards any recorded material from the last time Start Recording was pressed

  • Current recording duration

  • Microphone indicator - a visual auto meter that represents the current volume of recorded sound and should move as you speak

  • Notation tools (pencil icon) - clicking this opens the notation tools menu above the recording panel (seen in the upper half of the above image). You can draw (pencil icon), make arrows by clicking and dragging (arrow icon), write text (T icon), record the mouse pointer with "clicks" indicated visually (cursor/pointer icon), move notations by clicking and dragging (4-way arrow icon), change notation color, discard/clear all notations (trash icon), and adjust the width of notations (vertical slider).

Uploading Recordings to Kaltura

Once you click Stop recording and confirm you're ready to stop, you'll be automatically taken to the Manage page. You can change the title, add a description, and any tags you want. When you are ready to upload your recording to your My Media library, select "Save and Upload" then agree to the terms of use that appear. You can monitor the progress of the upload by selecting "Go to library" and viewing the progress bar next to the video's entry in the Kaltura Capture library list. You can also just save your recording and upload it at a later date from the Manage page.

After your video finishes uploading, the notification of success and the library entry will display a link to the video. The links displayed within the Kaltura Classroom app do not work with UW System's Kaltura implementation. To view your uploaded videos, access My Media within Canvas. To share an uploaded recording, embed it in Canvas or copy the share link from My Media.

OBS Studio can also be installed on your own computer from

OBS Configuration/Layout 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

  • Recording Quality: High Quality, Medium File Size
  • Recording Format: flv
  • Encoder: Hardware (QSV)
  • Custom Muxer Settings: BLANK
  • Enable Replay Buffer: UNCHECKED
  • 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.
  • 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.


    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 and selecting the video from your flash drive as the media file
