Own Your Workflow: An Open Source Automated Proxy Generation and Cold Storage Tiering MAM
. For creative teams, shared storage has always been a compromise. Local NAS appliances deliver performance but make remote collaboration difficult. Cloud object storage scales almost infinitely but often feels slow and awkward when working with large media files. Streaming solutions have proven that editors don't need to download an entire file before getting to work—but many of those platforms…
HuskHoard is an open-source tool designed to provide an automated proxy generation and cold storage tiering solution for video production workflows. Traditional storage options like NAS appliances and cloud object storage each have their limitations when it comes to collaborative editing of large media files. Streaming solutions often come with recurring subscription costs, proprietary infrastructure, and vendor lock-in.
HuskHoard aims to offer the benefits of streaming without being tied to a specific cloud service, allowing organizations to use their existing storage infrastructure while maintaining full control.
One of the key design principles of HuskHoard is that storage should be interchangeable, rather than being tightly coupled to a single cloud provider or appliance. This allows organizations to choose the storage infrastructure that best suits their needs, whether it be a local MinIO cluster, a TrueNAS deployment, an AWS S3 bucket, or a distributed Ceph object store. From the user's perspective, the workflow remains the same regardless of the underlying storage location.
Large media repositories can contain millions of files, and listing directories can become slow when every metadata lookup requires a network request. HuskHoard addresses this issue with a local SQLite catalog that indexes directory contents locally, making directory listings virtually instantaneous. This allows editors to browse enormous media libraries as if they were navigating a local filesystem, with folder trees expanding immediately and search operations remaining responsive.
The real innovation of HuskHoard lies in its approach to bridging the gap between active editing and cold storage. When high-res assets are tiered off expensive NVMe drives to cloud or tape storage, HuskHoard intercepts the PRE_ARCHIVE event and automatically generates lightweight, 720p H.264 proxy files using ffmpeg. These proxies replace the original files with transparent stubs, allowing editors to scrub timelines using the lightweight proxies with zero network latency.
When it's time for final conform or color grading, the NLE reconnects to the high-res files, which are rehydrated from the cold archive seamlessly.
HuskHoard also offers a distributed workflow solution using a Zero Trust Grid Mesh. This eliminates the laggy experience of accessing a central archive over an SMB share via a VPN. Instead, HuskHoard uses kernel-level integration with Linux's fanotify subsystem to intercept POSIX read requests to stubbed files. When a file is needed, HuskHoard recalls the high-res data from the cloud bucket or LTO tape, rehydrates it back to the primary disk, and continues the render seamlessly.
For final conforms, the sidecar features an API-driven PRE_RESTORE hook, allowing pipeline engineers to dynamically provision Linux named pipes and extract only the requested subclips on the fly, saving hours of transfer time during the final conform process.
