In the real world, you could barely make out (if at all) the burners on the Tomcat (B / D). You would only be able to tell by the noise level or looking into the cans. [ see photos above ]
The only time you could see them during the day was in low light (overcast) and high humidity.
The video you post is of a F-16 with a P&W motor. It had some of the most visible AB's and still does.
this one is rather overcast and you still cant see them.

Plus, seeing them as often as I did in person, it wasn't a "camera lighting issue"... you couldn't see them to the naked eye either.
