HTML `` is the de facto element we turn to for embedding video content, but it comes with constraints. For example, it downloads the video file linearly over HTTP, which leads to performance hiccups, especially for large videos consumed on slower connections. But with adaptive bitrate streaming, we can split the video into multiple segments at different bitrates and resolutions.

Last month, we improved our AI tooling to give you even more flexibility when combating fraud. Now, Radar’s new rules combine our machine learning models with the issuer’s CVC and postal code response in real time.
