5 Media asset management (MAM) systems sit at the center of broadcast, post-production and content owner workflows. They catalog every clip, program and graphic, track metadata and rights, drive transcoding and move content between storage tiers. As archives grow into petabytes, a common question is whether a MAM can use object storage directly, rather than only through file systems or tape. In many cases it can. Modern MAM platforms increasingly support S3-compatible storage as a native storage location, and object storage has become a popular foundation for media archives. The details matter, though: how the MAM reads and writes files, how editors access content and how metadata, proxies and partial restores are handled. This article explains how MAM object storage integration typically works, what to evaluate and how to test it. For where object storage fits among media storage tiers, see what a media nearline archive is. Why connect a MAM to object storage Scale: object storage grows by adding nodes, supporting archives of many petabytes. Cost: lower cost per terabyte than high-performance production storage. Accessibility: content stays online and retrievable in seconds, unlike tape. Durability: erasure coding protects against drive and node failures. Openness: the S3 API is supported by many media tools, transcoders and cloud services, reducing lock-in to a single vendor’s storage. Immutability: object lock can protect high-value masters from deletion or ransomware. Integration models Native S3 storage location The MAM treats an S3 bucket as one of its storage locations, writing and reading assets through the S3 API. It keeps its own database of where each asset lives and can move assets between locations by policy. This is the most direct model and the one most modern MAMs are moving toward. Storage tiering under the MAM The MAM writes to a file system, and the storage layer or a tiering product moves older files to object storage, leaving stubs or references. This can work with MAMs that lack native S3 support, but adds a layer to manage and can make performance less predictable. Archive management middleware Some environments use separate archive management software between the MAM and storage, historically to manage tape libraries. Many such products now support object storage targets, allowing the MAM to request restores without talking to object storage directly. Cloud-native MAM Some MAMs run in the cloud or as hybrid services and are built around object storage from the start, whether public cloud or S3-compatible storage on premises. Confirm which models your MAM supports, in which versions, and whether specific object storage platforms have been tested. What to evaluate Read and write throughput Media files are large. Archiving a day’s production or restoring a season of footage moves many terabytes. Check that the object storage platform and network deliver the throughput your workflows need, and that the MAM uses parallel transfers such as multipart uploads. S3 multipart uploads explains why this matters for large files. Partial restore Editors often need a short section of a long file, such as a few minutes from a full match. Restoring the entire file wastes time and bandwidth. Some MAMs and transcoders support partial file restore using byte-range reads from object storage. Check whether yours does, since it can greatly improve the user experience. Proxies and browsing Users search and preview content using low-resolution proxies. Proxies are typically stored on fast storage or a separate object storage bucket optimized for quick access, while high-resolution masters live on the archive tier. Confirm where proxies are stored and how quickly they load. Editing workflows Most professional editing applications expect file system access to high-performance shared storage. Object storage is usually not used for direct editing of high-resolution media. Instead, the MAM restores content from object storage to production storage when an editor needs it. Some newer cloud editing workflows read from object storage, but evaluate performance carefully. Metadata handling The MAM’s database is the authoritative catalog. Object storage can also store metadata with each object, such as asset IDs or tags, which helps with recovery and lifecycle rules. Decide whether to write key metadata to objects as well as the MAM database, so content remains identifiable if the MAM is ever replaced. File naming and structure Some MAMs write objects with opaque identifiers rather than human-readable names. That is fine for the MAM but can make the archive hard to use without it. Consider how you would migrate or access content if you changed MAM vendors. Lifecycle and tiering Rules in the MAM, or lifecycle policies on object storage, can move content between buckets or tiers, or expire temporary files. Make sure the two do not conflict. Security Use separate credentials for each workflow, restrict access to buckets, encrypt content and audit access. Protect masters with immutability where appropriate. Transcoding and automation MAMs orchestrate transcoding for proxies, delivery formats and partner versions. When source files live on object storage, transcoders either read directly over S3 or work from a copy restored to fast storage. Direct reads avoid duplicate copies and speed automation, provided the transcoder supports S3 input and the network can deliver the throughput. Outputs can be written straight back to object storage for delivery or archive. Many organizations also use object storage event notifications or MAM workflows to trigger processing automatically when new content arrives, such as generating proxies, extracting metadata or running quality checks. Designing these automations around object storage from the start reduces the number of copies scattered across production storage and keeps the archive the single source of truth. Operating the integration Once in production, monitor archive and restore queue lengths, transfer throughput, failed jobs and storage capacity. Agree on who owns each part: the MAM team for policies and workflows, the storage team for the platform, capacity and protection. Review storage locations and policies when new content types, such as higher-resolution formats, are introduced. On-premises or cloud object storage Both can work with MAMs. On-premises S3-compatible object storage keeps content local, avoids retrieval and transfer charges when content moves to production storage and supports predictable costs at scale. Cloud object storage suits cloud-based workflows and distributed teams. Many organizations use both: on-premises for the main archive and cloud for collaboration, distribution or disaster recovery copies. Data residency and rights considerations differ by region; European and Asian broadcasters often keep archives in national facilities. How to test before committing A proof of concept should cover: Archiving a representative set of assets, including very large files. Restoring full files and partial sections to production storage. Measuring throughput for bulk archive and restore operations. Searching and previewing with proxies. Simulating a storage node failure during archive and restore. Testing lifecycle rules and deletion. Verifying metadata is preserved and content can be identified outside the MAM. Testing immutability for protected content. Migrating from tape or NAS Moving an existing archive to object storage is often done through the MAM or archive management software, which restores content from the old location and writes it to the new one. Plan for transfer time, verification and dual operation. Digitization projects for legacy tape and film can feed directly into object storage. Checklist: MAM object storage Confirm the MAM’s S3 support model and tested versions. Size object storage and network for archive and restore throughput. Check multipart uploads and partial restore support. Keep proxies on fast storage for browsing. Restore to production storage for editing. Decide how metadata is stored with objects. Plan for MAM portability and object naming. Align MAM rules with storage lifecycle policies. Secure buckets, credentials and masters. Test failure, restore and migration scenarios. Putting it together A media asset manager can use object storage directly when it supports S3 natively, and doing so turns the archive into a scalable, online, cost-efficient resource. The keys are throughput for large files, partial restore, fast proxies, careful metadata handling and a clear path between object storage and production storage for editing. Test those with your own content and workflows, and the MAM and object storage together become the backbone of a modern media archive. For library delivery, see VOD library storage. Frequently asked questions Can a MAM store content on S3? Many modern MAMs support S3-compatible storage as a native storage location. Others use tiering or archive middleware. Can editors work directly from object storage? Usually not for high-resolution professional editing. Content is restored to production storage, though some cloud editing workflows read from object storage. What is partial restore? Retrieving only a section of a large media file, such as a few minutes from a long recording, using byte-range reads. Where should proxies be stored? Typically on fast storage or a dedicated bucket optimized for quick access, so browsing and preview are responsive. How do I avoid lock-in to a MAM? Store key metadata with objects, understand how files are named and ensure content can be identified and migrated without the MAM.
