Video transcode profiles
A video transcode profile is a set of video conversion settings used to convert source videos into formats suitable for a range of devices and browsers.
Your account will be provisioned with default profiles, including MP4-240, MP4-280, MP4-720, WebM-480 and WebM-720, with settings to match most common devices and browsers, but in some circumstances you may want to create a new profile or edit an existing one.
On this page we'll show how to create and edit profiles and set parameters including video codec and bitrate and audio options.
