How Can We Help?

Mukurtu CMS access copy sizes, resolutions, and file formats

Mukurtu CMS supports a wide range of file formats for audio, images, video, and files. These access copy recommendations are based on best practice recommendations and standards from industry experts for web ready access copies (see References at end of document). These standards are implemented in the Plateau Peoples’ Web Portal.

Your individual needs and internally-defined best practices and standards may vary from those identified here, these are tested, but are  a guideline for implementation.
