Watermarking is a method to place text or images on top of your video for security or to provide additional information.
Watermarking text or images on top of your video
- Edit the video you wish to watermark by clicking the edit button in the main Videos screen.
- Choose Settings -> Security Options
- In the Security Options page, you will see the Watermarking field at the bottom of the page.
Two methods for watermarking
Text - by clicking the "Text" radio button you can add in a single line of watermarking code and press Save. See Syntax for watermarking script markup below.
URL - for more complex watermarking that can change at different points of the video, click the "URL" radio button and input a hyperlink to a watermarking .def script markup file.
Syntax for watermarking script markup
Both methods require knowledge of the watermarking .def script markup. A demo .def file contains a commented script for this. Download and view it.
The example below displays a simple text message ("This is watermarking text") that begins at 0 milliseconds and will repeat at 40,000 milliseconds (40 seconds). It is encapsulated in a css div (pos1) that a web designer can define in the page. Using CSS you can then make the text message adopt a variety of styles (size, color, positioning).
ON: 0/40000, msg, <div class='pos1'>This is watermarking text</div>
Watermarking with dynamic text
Using CSS you can insert dynamic text where the value is defined by a variable on your page, for example with a user ID. In the .def script, instead of static text you can use a declared variable that exists on your page.
