YuJa (All Users) - Image Tools: Watermarks, Blur, and Virtual Background

This article walks you through how to add watermarks, blur a section of the video, and add a virtual background.

Before making any edits to a video, it is a best practice to make a copy of the video for a back-up. In the event that an error is made editing the video, the back-up will provide access to the original content. Follow these instructions to make a copy of the video.

The three image tools are:

Insert Watermark or Overlay

A watermark is semi-transparent text superimposed on a video. Its purpose is to warn viewers of copyright, of a draft not finalized, etc. Users will not be able to remove the watermark so make certain that the text does not block any thing of importance on the screen. An Overlay is text on the screen that is not faded. This can be used for adding information such as a webpage (not clickable), speaker's names, etc.

Both the Watermark and Overlay must be images (.png, .jpg, .gif, or .jpeg). You will not be able to type the text directly onto the video. Use the "Add Text Overlay" option. Watermarks are traditionally white text that is semi-transparent. Overlays will be any color that the image text is in. That cannot be changed once it is in YuJa.

  1. Navigate to the video's thumbnail and select Edit from the menu.

  2. If the Advanced Mode is not already Yes, toggle the Advance Mode to Yes.

    set advanced mode to Yes


  3. If the watermark will not extend the whole video, (e.g, for only 10 seconds), play or scrub the video to the point on the video where the watermark will begin.
    Select the Image Tools icon. Click Insert Watermark/Overlay from the menu.

    Insert Watermark / overlay


  4. Click Select File button and choose the watermark or overlay file from your computer.

    select file

  5. The "Video 1" displays a thumbnail of the video. For the watermark/overlay to run the length of the video, check the box "Apply Watermark to Entire Video." To select a specific time, uncheck that box and specify the number of seconds in the Duration box. You cannot type in the Duration box if the "Apply Watermark to Entire Video" box is checked.

  7. To change duration, double click on the watermark box. Change duration in seconds or check the  "Apply Watermark to Entire Video." Click the Apply button.

  8. If the watermark is in the wrong place, hover your mouse over the watermark and click the X in the upper right corner to delete it.

  9. Continue editing or click the Save button at the top of the page. If this is a duplicate video from the original, click Replace Existing Video. If you did not make a duplicate, it is a best practice to keep the original for archive purposes and click Save as New Video.

  10. The watermark will appear in the middle of the screen. Drag and drop it to a location where it will not interfere with the content. Click the Delete button on the watermark to delete it.

  11. Overlays will appear in the middle of the screen too. Move them to a location that will not interfere with the content.

Insert Blur

The Blur tool allows you to blur out a section of video for a limited duration. This option may be needed if sensitive information (e.g., social security numbers, grades, student images, etc) are displayed and should be hidden.
  1. Navigate to the video's thumbnail and select Edit from the menu.

    set advanced mode to Yes


  3.  Play or scrub the video to the point on the video where the blur will begin.  Select the Image Tools icon. Click Insert Blur from the menu.

    select blur

  4. A grey box will appear on the screen. Click and drag on the left side of the box to move the box. Click the drag lines in the lower right corner to make the box bigger or smaller. Adjust and/or move the box until it completely covers the area to be blurred. Note: You will still see some of the content below. That will be completely blurred after processing.

  5. Continue editing or click the Save button at the top of the page. If this is a duplicate video from the original, click Replace Existing Video. If you did not make a duplicate, it is a best practice to keep the original for archive purposes and click Save as New Video.

Add Virtual Background

Adding a Virtual Background may be necessary if the current background is distracting or to maintain privacy of your personal location. This includes, for example, a messy office, home, etc. The YuJa AI will replace the static background with an image,  leaving the human in front. This option should not be used to replace PowerPoint slides. The Insert Slide or Image tool would work better. SIUE has many virtual images you can download from: https://www.siue.edu/marketing-and-communications/services/graphic-design/wordmarks-for-download.shtml or choose your own image. 
  1. Navigate to the video's thumbnail and select Edit from the menu.

  3. Play or scrub the video to the point on the video where the virtual background will begin or leave the timeline at the beginning if the virtual background will cover the entire video.
    Select the Image Tools icon. Click Add Virtual Background from the menu.

  5. After you have selected the image, confirm the image you selected is correct. Confirm what video is being replaced. If you have more than one video stream select the correct one. Click the Apply button at the bottom of the window.

    select video stream

  6. A thumbnail with the replaced background will give a preview of what the background will look like.

  7. Click Close at the bottom of the window. Continue editing or click the Save button at the top of the page. If this is a duplicate video from the original, click Replace Existing Video. If you did not make a duplicate, it is a best practice to keep the original for archive purposes and click Save as New Video. After processing the original background will be replaced with the new virtual background.
