H.264 specifies a set of capabilities and different profiles that group subsets of the available capabilities. Ooyala supports the following profiles:
Although the High profile will give you better quality, it is not supported by all devices (including iPhones as they require the Baseline profile).
Note: For the same video, the Baseline profile can require up to a 20% higher bit rate to provide the same quality as the High profile.
