Screencast-O-Matic (SOM): Quick Start

Screencast-O-Matic (SOM): Quick Start

These are step-by-step instructions for recording a screencast with SOM.

Download and install Screencast-O-Matic.

Downloads are restricted to Faculty and Staff only.This software will not appear on the UVM Software site for Students. Only UVM Faculty and Staff will be able to see and access the download link. A free version of Screencast-O-Matic is available for basic recordings on the web.

Make an outline or script of your screencast

Keep it short. If you’re recording lecture content, do 10 minute or shorter chunks (by topic) so your students can easily (re)find information.

Record a screencast with one of two options:

Recording a Spontaneous Screencast (send to SAS for captions)

  If you already have slides or content created that you would like to narrate and publish as videos for students, creating an informal spontaneous screencast is a good solution. Spontaneous recordings provide options for recording your screen, your webcam, or both.
      1. Go to your account page and click “start recorder” or if you prefer to record in a downloaded SOM app, click the red “Record” button in the top right corner.
      2. Choose whether to record the screen, webcam, or both.
      3. Ensure that you have given permission for SOM to access your microphone (WindowsMac) and camera.
    Use 720p for the size of your recording  We recommend resizing the objects (Powerpoint, website, document, etc.) that you are recording to fit in the default-sized 720p recording window. Watch this tutorial for more guidance.
      1. Use the record and pause buttons to start and stop.
      2. Send a link to your video to SAS’s captioning services using this form after uploading to UVM Streaming.
    Speech-to-Text Captions Not ADA Compliant  While Screencast-o-matic does have a speech-to-text caption creation, these are not ADA compliant.

Recording a Scripted Screencast (will generate perfect captions)

  The Scripted Recording feature allows you to follow the best practice of screencast recording by making audio and video tracks separately. And, starting with a script helps to create a professional product. Scripted Recordings save time because you’ll automatically create accurate closed captions and reduce the need for editing.  
Record Word-for-Word to Create ADA Compliant Captions  When recording the audio of your script, if you change a word, add a phrase, or make a parenthetical comment, you must then edit your script to match what you’ve said in order for your captions to be ADA compliant. Or, you can re-record the audio to match the script as you have written it. Make sure that the written script and the recorded audio match precisely.  
  1. Download the SOM app.
  2. Ensure that you have given permission for SOM to access your microphone (WindowsMac) and camera.
  3. Follow this tutorial.

Edit your screencast, if desired

Do not strive for perfection. These are common editing needs:
Access Additional Editing InstructionsScreencast-O-Matic has more instructional videos about various editing features. This video editor cheat sheet may also be of use.
Click “Done” when finished editing in order to save your video.

Save your screencast

Save your screencast as an .mp4 file and publish it to a place you will be able to find when browsing. Screencast-o-matic files are large. If you save them to your hard drive, you may run out of room. We recommend either saving files to your UVM OneDrive cloud storage or exporting compressed files to an external hard drive or cloud storage. If your .mp4 file is blurry when viewing, save as a higher quality file, which will take longer to upload to UVM Streaming, but will result in a clearer product.

Add captions to spontaneous screencasts

Send your .mp4 file to Student Accessibility Services for captioning if you created a spontaneous recording. If you recorded a scripted screencast, your captions should already be included in your saved .mp4 file.
ADA Requirement for CaptionsADA compliant captions are required if you have students with accommodations for captions and are always recommended.

Upload your .mp4 to UVM Streaming and share with your students

Follow this step-by-step tutorial to learn how to upload your captioned .mp4 file to UVM Streaming and share your video with studentsUVM Streaming is like UVM’s own YouTube channel, but on a UVM Server. By putting files on Streaming, you will not slow down your Blackboard course site. Most frequently, we expect you will be putting links to videos in Blackboard, but you can share the links via email, MS Teams, etc.

Use Screencast-O-Matic’s tutorials for more advanced features

Once you get comfortable with SOM, you may want to use more sophisticated features. Check out the entire suite of tutorials offered by SOM to enhance your skills.


Disk too full error

  If you get the DISK TOO FULL error it means your computer’s hard drive is too full so the recorder can’t record. Screencast-O-Matic has provided this guide for assistance with freeing up space on your hard drive.

Screencast-O-Matic: Install & Setup

Download & Install Screencast-O-Matic (SOM)

Now you’re almost ready to roll camera.  Before recording your first screencast, you may need to make a few permissions changes.

Allowing Camera & Microphone Access

SOM may need permission to use the camera and microphone.  The steps to do this vary by operating system.

MacOS Catalina

Due to security/privacy restrictions in MacOS, you will need to specifically allow SOM to use your devices.  The following steps outline how to do this in MacOS Catalina:
  1.  Go to System Preferences -> Security & Privacy.
  2. Click on the lock button at the bottom left and enter your login to allow changes. 
  3. Scroll down on the left column and select Screen Recording, then check the box next to Screencast-O-Matic v2.0.
  4. Select Accessibility from the left column, and check the box next to Screencast-O-Matic v2.0.
  5. Select Microphone from the left column, and check the box next to Screencast-O-Matic v2.0.
  6. Scroll up and select Camera from the left column, and check the box next to Screencast-O-Matic v2.0.


Recording audio in windows can be done by enabling that setting in the SOM recorder.
