Containers, Video Codecs, and Audio Codecs

Each encoding is a container format (e.g. MP4) which comprises a video and audio codec.

When specifying a processing profile, the container formats and audio formats must be specified.

H.264 specifies a set of capabilities and different profiles that group subsets of the available capabilities. Ooyala supports the following profiles:

  • Baseline
  • High

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.
