Watermark Image URL
mark
Specifies the URL of the image to use as a watermark overlay on your video.
The mark parameter accepts a URL-encoded image URL. The watermark image will be overlaid on top of your video throughout its entire duration. You can control the watermark’s appearance and position using additional parameters like mark-align, mark-alpha, mark-w, and mark-h.
The watermark URL must be properly URL-encoded. For example, https://assets.imgix.net/watermark.png should be encoded as https%3A%2F%2Fassets.imgix.net%2Fwatermark.png.
