Delivering to Mobile Screens
Tremor Video DSP recommends including at least one < 3MB media file in your ad tag when delivering to a mobile in-app screen. This limitation helps to standardize user experience across different connection speeds such as 3G, 4G, LTE, wifi, and so on.
When the video file size is larger than 3MB, there can be a 1-2 second delay in loading the video ad, which can cause some mobile publishers to abandon the ad, causing use rate issues for the delivery of this placement.
