Convert the RGB to YCbCr, embed the watermark on the Y pane, and convert the result back to RGB.

Depends on what you want to do - how you want to do it. One way is to just take a weighted average of the images if you want the watermark to be a visible "video bug" on the image. There are other ways of course, like if you want a solid background or transparent background. If you just want to paste the smaller watermark image onto the larger main image, see my attached copy and paste demo. If you want a hidden watermark you can use steganography, like the attached demo.
