ListenLoop accepts VAST 2.0, Inline video assets for your ABM advertising campaigns. 

Raw videos should be uploaded in .mp4, .mov, or .flv formats. ListenLoop will transcode the videos into multiple formats and bit rates for optimal delivery across platforms.

ListenLoop does not require any specific dimensions. But please note that your video will have black bars inserted on the sides or top/bottom to fit the dimensions of the video player where it is served.  Accordingly, we recommend using common video formats, such as 240p, 480p, 720p, or 1080p.

Your video asset should be 30 megabytes or smaller.  Upon request, however, you may upload 100 megabyte video files.

Finally, we recommend that you limit your video content's duration to 15 seconds (best), 30 seconds (good), or 60 seconds (OK).  Longer duration is possible though finding inventory for non-standard durations will be more difficult, and you should expect much lower volume.

Pro Tip:  You may wish to add an image (with extension .gif, .jpg, .jpeg or .png) as a companion asset in order to provide a backup should your video not load for some reason.
