MPEG2 video has been the de facto mezzanine and broadcast video standard for decades. It is still widely utilized in HD broadcast applications, as well as for predictable and reliable storage of mezzanine files at constant bitrates.
Encoding.com supports a wide variety of parameters for producing compatible MPEG2 video output for a variety of linear playout systems and MAM/DAM storage, including CableLabs compliance in MPEG transport streams. Please reach out to our support team if you have a specific scenario requiring frame cadence, GOP, or colorimetry, as we've likely designed a job template before to match your needs.
