In order to build Video banners with time tracking use Adform Creative Toolkit. More info here.
Video banners in devices which do not support Flash
Some devices as iPad or iPhone do not support flash-based content. If a user visits a media site using such a device then instead of the video banner (Flash content) an image or an empty space is shown. In order to avoid such situations Adform replaces images (or empty spaces) with HTML5 video banners. All you have to do is to send video files of following types:
a. H.264+AAC+MP4 for IE9, iPhone 3.0+, iPad, Android 2.0+
b. Theora+Vorbis+Ogg for Firefox 3.5, Chrome, Opera
c. WebM for Firefox 4.0, Android 2.3+
Rich Media video banners will work in following way:
a. If it's possible to play Flash video - flash video will be played
b. If it's not possible to play flash video but it's possible to play HTML5 video - HTML5 video will be played (for expanding and tear back banners HTML5 video will be shown only in expanded state, in collapsed state backup image will be shown)
c. In worst case backup image will be shown
