Introduction
In online teaching, lecture videos are the most valuable assets for instructors.
They represent hours of preparation, years of teaching experience, and accumulated expertise.
That’s why many educators are concerned about:
- Videos being downloaded illegally
- Logos being removed or videos re-uploaded to other platforms
- Wanting to add a watermark but worrying it will ruin the video or distract learners
In reality, watermarks are not meant to “ruin” videos, but to protect content in a subtle and professional way.
This article focuses on how to add watermarks correctly to lecture videos, especially:
- The ideal percentage ratio between watermark and video frame
- Position and opacity that protect content without harming the learning experience
- And how to implement watermarks directly on teaching platforms like Ourdemy
1. Watermarking lecture videos: how to do it right without backfiring
Watermarks help protect content, but only when used correctly.
Many lecture videos look unprofessional not because watermarks are bad, but because they are used improperly.
Common mistakes
❌ Watermarks that are too large
- Cover slide content
- Become annoying during long viewing sessions
❌ Placing the watermark in the center of the video
- Constantly draws attention
- Significantly reduces learning experience
❌ Incorrect opacity settings
- Too transparent → no real protection
- Too opaque → ruins video layout
❌ Inconsistent watermark styles across videos
- Looks unprofessional
- Fails to build long-term brand recognition
👉 To avoid these issues, it’s essential to understand proper watermark size ratios and placement principles.
2. Creating and adding watermarks that are clean, professional, and learner-friendly
A watermark is only effective when it is designed properly from the start and applied correctly.
Depending on your situation, instructors can begin with one of the following two cases.
Case 1: You don’t have a watermark yet
If you’ve never used a watermark before, or you’re unsure whether to use text or a logo, start here.
If you already have a watermark, skip to Step 3 below.
Step 1: Choose the right watermark type for lecture videos
For educational videos, watermarks don’t need to be complex.
The two most common types are text and logo.
Text-based watermarks work well if:
- You teach as an individual instructor
- You don’t yet have a brand logo
- You want videos to feel clean and lightweight
Examples:
- John Smith – Online Course
- Instructor Name | Course Title
Logo-based watermarks are suitable if:
- You run a center or established brand
- You want to use the same watermark across multiple courses
👉 Key principle: the simpler the watermark, the better the viewing experience.
Step 2: Create a watermark quickly (no design skills required)
Instructors don’t need design expertise to create a watermark.
You can:
- Use basic design tools like Canva or Figma
- Or use AI to suggest watermark content
Once you decide on a direction:
- Export a simple text or logo watermark
- Prepare it for use in your videos
Case 2: You already have a watermark → apply it correctly to your videos
This is the most critical step.
Even a well-designed watermark can make videos look unprofessional if applied incorrectly.
Step 3: Set watermark size based on video frame ratio
A good watermark is usually smaller than you expect.
For lecture videos:
- The watermark should take up about 3–5% of the video width
- For Full HD videos (1920px wide):
- A watermark width of 60–100px is sufficient
👉 Quick check:
If the watermark is noticeable when you look for it, but not distracting during normal viewing, you’re doing it right.
Step 4: Adjust opacity so the watermark doesn’t distract learners
Opacity directly affects viewing comfort.
- For lecture videos, use 10–20% opacity
- Thin text watermarks → up to ~20%
- Logo watermarks → best kept around 10–15%
👉 Simple test:
Watch the video continuously for 1–2 minutes.
If you stop noticing the watermark, the opacity is appropriate.
Step 5: Choose watermark placement based on video layout
Not every “empty” spot is suitable for a watermark.
Recommended positions (safe & common)
- Bottom-right or bottom-left corner
- Offset slightly from the edge (about 20–40px)
These positions:
- Rarely interfere with content
- Are easy to keep consistent across the course
👉 Important: choose one corner and use it for all videos.
Positions that require caution
- Top corners: only suitable for slide-heavy videos
- Center: only for preview/demo videos, and must be very faint
Positions to avoid
- Directly over lesson content
- On top of slide text or subtitles
- Overlapping the instructor’s face cam
💡 Tip:
If your video includes a face cam, place the watermark on the opposite side of the instructor’s face.
Step 6: Keep watermark usage consistent across the entire course
Professional courses rely on consistency.
Avoid:
- Different watermark positions per video
- Changing sizes or opacity levels
👉 Best practice:
- Use one watermark
- Maintain one size
- Maintain one opacity level
- Maintain one position
→ Apply this consistently across all course videos.
Step 7: Test before applying at scale
Before publishing, instructors should:
- Test the watermark on 1–2 sample videos
- Watch on both desktop and mobile
- View continuously for a few minutes
👉 If viewers aren’t distracted, the watermark is applied correctly.
3. Implementing Watermarks for Lesson Videos on Ourdemy
When uploading your course to Ourdemy, instructors can apply watermarks to lesson videos in a simple and consistent way, without the need to manually edit each video before uploading.
Using watermarks helps protect your content while maintaining visual consistency across the entire course.
Ourdemy supports applying watermarks directly within the platform, allowing instructors to save time and easily manage updates or revisions to videos in the future.

Conclusion
A small watermark goes a long way in protecting content and building long-term value
Watermarks are not about making videos harder to watch. They are about:
- Protecting instructors’ hard work
- Standardizing online courses
- Demonstrating professionalism through small details
Just get three things right:
- Correct size ratio
- Correct placement
- Correct opacity level
And the watermark becomes a natural part of the lecture video—learners aren’t distracted, but your content stays protected.
