This option will not work as intended if embedded with externally hosted videos.
This is an option that is available for any user which is on any of Brid's paid plans.
Brid makes special, separate video and audio renditions so that your video assets are properly encoded for this feature to work correctly.
If you plan on monetizing these videos with this feature on, keep in mind that only pre rolls will currently work and display.
If your VAST tag contains ad creatives that are properly prepared for in-page playback on iPhones, then your pre roll will also display in-page. If not, the player will release control to your mobile device and let it take over the display of the pre roll in full screen as is normal for any video on iPhones.
As in Facebook, your video will autoplay and start muted. Once clicked, the player will open up and sound will start playing.
