In-banner video can be host-or-user initiated up to :30 seconds and must have standard controls (i.e. play/pause, audio/mute, and stop). Audio must be user-initiated, except for In-banner Video ads in Expandable banners when expansion is on click. If expansion is on rollover/mouse over, audio must be user-initiated on click.

CNN.com will NOT allow any in-banner video ads on the multimedia story pages and video section as those pages will have a pre-roll synced with a 336x280 banner.
