Why add video to your lessons

Video is one of the most effective ways to teach. A short, focused video showing a concept or walking through a technique can communicate more than pages of text. When you upload a video to Ruzuku, we host it for you and automatically convert it into a web- and mobile-optimized format with adaptive streaming. That means the player adjusts quality based on each student's device and connection speed.

Ruzuku supports MP4 and MOV files in any resolution, including 720p, 1080p, and 4K.

File size limits: Up to 2 GB per video on Core plans, 4 GB on Pro.

Tip: Name your video file simply — lowercase, no spaces or special characters. This helps ensure the smoothest upload and conversion.

Upload a video

Open your course and go to Manage Course (keyboard shortcut: Cmd+K on Mac, Ctrl+K on Windows).
Click Modules & Lessons in the Content column.
Click the lesson where you want to add a video (or click Add Lesson to create a new one).
In the lesson editor, click Add media, then select Video or audio file.
Choose how to add your video:
- Choose file to select a file from your computer (drag and drop works too).
- Record Video to record directly in your browser.
If you chose a file, select the video from your computer and wait for the upload to finish. Upload time depends on file size and your internet connection.
You'll know the upload is complete when you see a checkmark and "saved" in the upper right corner of the editor.

Set a poster image

The poster image is the thumbnail students see before they press play. By default, Ruzuku uses the first frame of your video. Here's how to pick a better frame:

Click on the uploaded video in the lesson editor.
Click the Change Poster Image icon that appears.
Drag the video cursor along the bottom to find the frame you want.
Click Set Poster Image to save your selection.

Preview your video

Click Student View in the upper right corner of the lesson editor to see exactly what your students will see, including how the video plays. Click the editor toggle at the top to return to editing.
