block pop-up ads in iframe

I have a wordpress website where i embed third party videos " hosted on their servers " . But they have a lots of ads running in their video player , like pop up ads and notification ads, when user click on the video to play or pause the pop up ad opens. I want to block those ads on my website for clean user experience. NOTE = I used sandbox attribute in the iframe code to block their ads and they also have sandbox protection check. If they detect sandbox in iframe code the player won't load the video and gives an error. So if you know how to get around their sandbox attribute protection check then please let me know we can start immediately. The Iframe code which i used. <iframe src=" Third party video url here" sandboxscrolling="no" frameborder="0" width="700" height="430" allowfullscreen="true" webkitallowfullscreen="true" mozallowfullscreen="true" sandbox="allow-scripts"></iframe> If you need any information please don't hesitate to ask me.
