The preservation of multimedia content comprising audio, video, images, and interactive formats has emerged as a critical challenge in the digital age. Rapid technological evolution, format obsolescence, hardware degradation, and legal complexities threaten long-term accessibility and usability. This paper explores the strategies, technologies, and policies essential for preserving multimedia content within digital libraries and institutional repositories. It analyzes existing frameworks, metadata standards, and preservation tools while addressing key challenges such as format migration, copyright, and storage scalability. The study underscores the need for sustainable, interoperable, and collaborative preservation approaches to ensure multimedia heritage remains accessible for future generations. Ensure that multimedia archival materials (images and audio-visual materials) within Library & Archive NT (LANT) holdings are created and preserved to a consistent standard. These guidelines are also to be used as the minimum technical requirements of digital materials within the LANT repository Territory Stories (https://territorystories.nt.gov.au/). However preserving multimedia content poses unique and multifaceted challenges that differ significantly from preserving static textual documents. Unlike text, multimedia formats are inherently dynamic, technology-dependent, and often require specific hardware, software, and codecs for playback. Furthermore, the rapid pace of technological advancement can lead to the obsolescence of formats and platforms in just a few years, thereby threatening long-term access and usability. Institutions must also establish clear policies for copyright, licensing, and user access, while ensuring interoperability and long-term sustainability through collaborative networks.
