This post, kindly provided by Module Leader David Thewlis, discusses the use of OpenShot Video Editor to add overlays into videos for teaching.
Check out the resources section at the bottom of this post for step-by-step guides.
Why I use overlays?
I started my approach to online lecturing by recording in PowerPoint. Then I moved to recording in ReCap/Panopto. Neither were quite right for me, I felt limited in my delivery compared to in-person teaching. I found using props difficult when you only take up a small portion of a screen and emphasis on what really matters can be lost when you can’t feel the energy of the room.
I realised my biggest issue with my lectures was that I was relegated to a tiny corner and the slides had become central.
You want the slides to be condiments to what you’re saying, not be the main event.
Bell Hooks writes about academics hiding behind the pedestal lose engagement with the class. Unfortunately, online lectures can create a similar barrier between us and our students. Overlays is the approach I decided on to help reduce this barrier in my teaching.
I hope I am not the only person who spends hours watching videos on YouTube for inspiration. The videos I found most interesting (even if they were long) were simple speaker focused talks, which showed media when it was helpful. Replicating this type of content was my aim.
What can you use overlays for?
Overlays replace slides by allowing the speaker to have greater control over where and when to place media. You can incorporate pictures, videos, audio, and titles into a single talk with reasonably little skill (I have managed – you can too!). You can choose to direct focus in the frame. Wes Anderson has made a film director’s career out of this skill, perhaps we can learn from it.
Types of overlays:
Picture – these can act very much like slides. Placing them in a corner of the screen, or covering the whole screen can offer different experiences.
Titles – these are text which appears in picture. They can be used as a title, but I like to use them to correct a mistake I’ve made in wording I also use them to throw forward to an idea or call back something discussed earlier in the lecture or course.
Video – adding another video within your video can serve as a much better example than just simple explanation. I have done this a few times with examples of good teaching models recorded by my colleagues. I have also seen some effective uses of people having brief conversations with themselves using picture in picture overlays.
Audio– if you have a flair for the dramatic backing music might help at some point in your talk. Audio Commentaries can also create a richer resource, see our case study.
Emojis – They’re there. Why not?
How I set up overlays
You will require some basic video editing software – I like OpenShot Video Editor. It’s free and reasonably simple. Simplicity is the theme of my advice.
1. Create/choose your media
Create a recording of your lecture using whatever recording device you have available. Errors or issues with the recording can be fixed in the editing process if needed. In this example on YouTube an instructor made a mistake with wording. Rather than re-record the entire video, which is otherwise good value, they corrected with an overlay title.
Making your images can be equally as easy. Saving pictures to an appropriate folder is one approach. I like to insert my pictures into a PowerPoint presentation to give myself the opportunity to get the structure clear in my head. I then save each slide as a picture.
2. Organise your content
Keep it simple and experiment with different formats. Layouts, text sizes, fonts, and colours all can have an impact on what you are communicating. Ensure that your titles are legible, and contrast appropriately with your background. I like the background to be the video of me generally, but I’ve seen solid examples of it being a slide or set of slides.
3. Put the video together
I recommend you take your time editing your first few videos.
Regardless of the software you decide to use I recommend you save your project often! Losing an almost completed video is very frustrating.
You can clip your videos to remove errors. Insert other videos in the middle of your talk. Explore effects if you are delivering a narrative.
The export time can be quite long (mine usually run around 40 minutes for a 10-15 minute video). This is an opportunity to make a coffee, have a stretch, and look away from a screen.
Although it may need more initial time investment it is worth it. Using overlays can add a personal touch to any asynchronous video content.
The MBBS programme collects a lot of assessment information that needs to be displayed in a way that is useful for the students, so that they can improve their grades through focusing on the right areas. They called upon the web skills of the FMS TEL team to design and implement a web application that could take assessment results, process them, and show them to the students in a visual and interactive way.
The first step towards this was agreeing a template that the results could be stored in. The types of assessments the MBBS programme uses are varied and quite detailed in their scope. They required a means to take all of this variation and detail and create something useable. The assessment team started by using complex Excel documents to collect and store all the assessments results. Each assessment type (WriSkE, MOSLER, SBA, OSCE…) needed a unique Excel template to store all the student scores and a way to map the assessment structure to the curriculum outcomes.
Processing the Spreadsheets
Once we had agreed on the template structure, we could then focus on how we would process them for use in a web application. We planned for the heavy concurrent use the web application would undergo when all the students logged in and tried to access their grades at the same time. The best solution for this was to minimise the use of complex database structures and instead store the results in pre-processed files, one for each student per assessment. The format we chose for this was JSON and this allowed us to rely on the speed of the server to provide the data.
Custom processing scripts were written for each assessment type to create these files. This would mean an administrator from the assessment team could log in to the site, go to the admin tools, choose an assessment type, set up a few settings including a release date, attach the assessment to an uploaded taxonomy (this attached the exam structure to learning outcomes), attach Excel file and process. The site would then go through the spreadsheet and create each assessment file ready for the students.
Display the Results
The final step was to decide how to display this detailed assessment information to the student. We chose to use an online chart library called highcharts. This allowed us to utilise a whole suite of charts and graphs to display the raw results in an interactive way.
One of the core charts we used was quartile (boxplot) graphs, which allowed us to plot the students scores against the cohorts. This means that students can see how they are performing in the context of their cohorts, which many of them appreciate. We also heavily use bar charts you can drill down into, and spiderweb charts that could show the same information in a visually different way. Letting the students modify and change the display to their preferences was also key.
Finally, we added tabs to show the exam structure and an area to which support documents could be added, such as assessor comments.
Each time a student clicked on an assessment, the site would load their file and convert into a visually rich interface of charts, graphs and links to drill down into the data.
System Success and Expansion
The FMS Feedback system has been successfully used by the MBBS programme since 2014. It is held in high regard by the administrative team who appreciate its flexibility and ease of use. For students, the detailed data displayed allows them to have a very granular understanding about their levels of mastery of individual skills and topic areas, and to spot patterns in their performance. This means they can focus their studies on areas identified for improvement, with a view to increasing their overall competency.
It has since been expanded to cover a few assessments from dental programmes that had a similar structure and process to the original MBBS assessments, such as SBA and OSPE’s.

The FMS TEL team participate in an annual study day on the Utilising Technology in Medical Education (UTME) module offered by the School of Medical Education.
The module aims to raise students’ awareness of how technology enhanced learning is currently used in health care education and gives students the opportunity to explore technologies and investigate theoretical underpinnings. Based on these aims we put together a 3 part presentation.
Part 1 – Tools for Student Interaction
Emily introduced a number of TEL tools including; Menti, vevox and padlet. Each tool was discussed; outlining its uses, pros and cons. Current examples of content designs, interactive activities and animations used throughout the faculty were shared.
Part 2 – Collaborating and Facilitating Group Work
Simon demonstrated how to use Microsoft 365 to co-author and co-edit documents, presentations and spreadsheets. Students were shown various features including; reviewing mode, version history and how to use Sharepoint to monitor breakout room activities.
Part 3 – Teaching Tools
Eleanor shared her experience of teaching with Zoom/Teams and tips on how to humanise online sessions. She discussed common barriers, such as awkwardness or long silences and strategies or tools to use as solutions.
This video was originally designed to be watched in a classroom setting, where the video would be paused for an in class discussion. When the course was moved online we used H5Ps interactive video to auto pause at the right moment and we embedded the video in a discussion board.
We created a 360 tour through a large lab in the School of Biomedical and Nutritional Sciences. This was to familiarise students with the lab before attending in person, but also to show the labs to students working at a distance.
We created a 360 image of the new Nutrition Kitchen with hotspots highlighting some common hazards. Clicking on the hotspots will show a close up image of the hazard and/or some information on why it is a hazard.
Locking your computer is good practice when you have to leave it to go somewhere. If you’re in a hurry you want a quick way of doing this.
Windows: Windows key + L
Mac: Control + Command + Q
This quick shortcut locks your computer much faster than going through the menu to do so, and very important in shared spaces. Pressing this key combo will instantly lock your computer and show the login screen.
It was nice to see some familiar faces and meet new colleagues at last week’s Learning and Teaching Conference. Members of the FMS TEL team took turns answering queries during sessions breaks. We also had the opportunity to attend the talks ourselves, and pick up some helpful tips and tricks!
At the desk we were pleased to see a number of visitors take copies of our booklet, showcasing some of the best posts from the FMS TEL blog.
A piece of research I have recently been involved in has been published in the BMC Medical Education online journal and is available to read now. It can also be accessed via the University library here.
The paper, titled ‘Evaluation of the Training in Early Detection for Early Intervention (TEDEI) e-learning course using Kirkpatrick’s method‘ focuses on the need for training of healthcare professionals in early detection of atypical motor development (cerebral palsy) in infants up to six months old.
Working in collaboration with Dr Anna Basu and Janice Pearse as Subject Matter Experts (SMEs), I developed a video-based e-learning course to address this need, with results from a pre-course and post-course quiz being analysed to evaluate whether participation in the course had improved knowledge and changed the behaviour of healthcare professionals.
The two-hour course used a Traffic Light System to both demonstrate abnormalities and also quiz users on their understanding of them, and the potential need to monitor/refer.
As demonstrated by the research, the course received positive responses from all stakeholders. Healthcare Professionals (HCPs) who have taken the course have improved their knowledge and confidence in this area, leading to better outcomes for families.
The course is available free to staff from Newcastle upon Tyne Hospitals NHS Foundation Trust. More information about the course, including access and booking, can be found on the University Website.
