As online education continues to grow, high-quality audio visual (AV) content plays a crucial role in student engagement and learning outcomes. Well-designed video, images, slides and more can dramatically improve the online course experience compared to just text. This blog will provide tips and best practices for developing various types of engaging AV materials suitable for a range of online courses. Key considerations around video, visuals, audio and content structure will help educators create impactful virtual learning experiences.

Video Production Tips

Video is one of the most powerful forms of online content, so it's important to plan filming and editing carefully.

Use a tripod or stabilizer and pay attention to framing, exposure and focus. Blurry or distracting footage reduces engagement.
Light yourself against a plain, non-distracting background. Avoid backlighting or spotlights that make you look shadowy.
Record in a quiet space without echoes or ambient noise. Use an external microphone for best audio quality.
Don't make videos too long - 5-10 minutes is typically the ideal length to retain attention.
Animate PowerPoint for slide-based video recordings to keep videos lively.
Add closed captions to make content accessible and searchable.

Visual Content Best Practices

Effective visuals inform and reinforce concepts discussed in videos or text.

Use high resolution photos, graphics and diagrams to clearly depict processes.
Include captions to describe images and their relevance for scanning viewers.
Annotate images during videos to draw focus to important areas.
Infographics, mind maps and other visual formats organize complex topics at a glance.
Poll or quiz images can make courses more interactive.

Audio Considerations

Your voice and any inserted audio must come through clearly on all devices.

Record audio at a consistent volume and speed without excessive vocal hesitations.
Remove any background noise in your recordings for better intelligibility.
Add background music sparingly and make it non-distracting.
Ensure any inserted audio like sound effects or clips are properly licensed.

Content Structure and Organization

Careful sequencing optimizes learning through small, digestible content chunks.

Break course content into logical modules and bite-sized lessons.
Number or subtitle sections to help viewers navigating on-demand.
Consider providing a sequential “play all” option as well as selective viewing.
Periodically recap or preview to reinforce links between topics.
Add review questions, polls or reflections to reinforce learning.

Creating Video Lectures

When creating screencast style video lectures, focus on interaction and visual aids.

Share your screen and comment on notes, slides or live coding demos.
Periodically look at the camera to engage distant students face-to-face.
Don’t just narrate slides - utilize animations, highlighting and other interactions.
For discussion-based content, record content collaboratively or invite live chat.

Interviews and Student Showcases

Interviewing experts or showcasing student projects personalizes online learning.

Ask open-ended questions and listen actively to interviewees on camera.
Share relevant student work like design portfolios, performances or lab reports.
Obtain releases and permission for any identifiable individuals depicted.

Production Tips for Mobile and Social Media

Optimize videos for mobile playback with vertical formats and smaller file sizes.
Tease noteworthy clips on social platforms while linking to full course videos.
Use animated slides, captions and graphics tailored to smaller phone screens.

Assessment and Feedback Videos

Record mini tutorials, lectures or simulations explaining key exam concepts.
Create video feedback for assignments discussing high and low points anonymously.
Host live or recorded question & answer sessions addressing student queries.

In conclusion, strategic use of high-quality, well-organized audio visual elements can greatly boost learner engagement with online courses. With careful planning for production, content elements and student needs, educators can offer immersive virtual learning experiences on par with traditional classrooms.
