VIDEO Interstitial:

Best Practices:

Video Interstitial

Since the user can scroll down to close the video, there is no specific time length on animation.

Audio must be user initiated by clicking on a volume icon located at top-left corner.

Less is more.  If you give the reader too much info, there’s no reason to click. 

Although the maximum file size is set to 30MB, make the video files as low as possible to avoid streaming issues on our sites.

For Celtra Ads, do not place text lower than 20% from the bottom. Text placed lower is at risk to be cut-off on smaller screens.
