 * I have never used Oxygen (the pagebuilder, I guess) Gerald, can’t comment. Can
   you share a URL so I can have a look?

 * Hi,
    Thanks for your quick answer. yes this is the Oxygen builder page. My page
   contains a video and I wanted to upload calls to youtube javascript files. (grade
   f in GT metrix and 3.6 s of loading). My url: [https://la-region-du-web.fr/referencement/audit-de-referencement/](https://la-region-du-web.fr/referencement/audit-de-referencement/)
   I performed wizard [https://la-region-du-web.fr/?aj_simulate=async.Async](https://la-region-du-web.fr/?aj_simulate=async.Async)
   Properties were not added to the script link. I hope this will help you. thank
   a lot Gerald

 * Salut Gerald;
    As YouTube video’s are loaded in an iframe, the JS in the iframe
   is out of reach of AsyncJS. Consider using a video lazyload/ lyte youtube plugin
   maybe?
 * hope this helps,
    frank

 * Hi,
    thanks for the advice. I have tried a lot of lazyload application. They 
   are not compatible. I tried with velocity, the video is not displayed on mobile…
   Thank you. By Gerald

 * Hi,
    Thanks it works and the plugin is great but it did not improve the performance
   of defer parsing. The youtube files are still loading.thanks Gerald
