IBV format is basically an HTML5 video banner, that takes up regular banner placements, and also the IBV format follows regular banner sizes.
In Eskimi DSP we serve IBV video in 300x250 size.
When uploading IBV video to Eskimi DSP, our dashboard will take the file and will first convert the dimensions of the video to 300x250, then if your video for example is in 16:9 aspect ratio, we downscale the video and add letterboxing automatically, in order to scale the video properly to the 300x250 dimension.
Duration: the maximum duration of the IBV video can be up to 30 seconds. This is the maximum time, which is recommended by all exchanges. However, if you will upload a video that is longer than 30 seconds, the user will be prompted to interact with the ad in order to continue watching the video.
Companion Banner (optional): as well every dashboard user has the option to upload a companion banner. This is a regular image that can be shown when the video ads, but it is not required.
The dimensions of the image should be 300x250, file formats: .PNG, .JPG, .JPEG, max file size: 150 kb.
Description (optional): here you can add a short 90 character description of your video ad.
