Clever Media Management for Film Productions

Silverstack is your tool for media acquisition and professional data management. Silverstack imports and handles any kind of camera and media format. In fact, Silverstack offers a flexible way of data handling by supporting any kind of file format. This includes sound files, photos, any camera media, and all other production documents.

Benefit from Silverstack

Superfast and simultaneous – automatically backup, structure, and manage your movie data with the highest efficiency.

Silverstack is the most comprehensive software for securely backing up footage and ingesting data in a fast, organized, and transparent way. Either on set, near set, or in post-production environments Silverstack lets you instantly secure data, preview source material, and create all kinds of reports based on one central metadata library.

The professional handling of digital media assets with the right set of powerful and innovative features gives you and your team maximum confidence to cover production-critical tasks with the greatest control and care.

Unrivaled Data Processing

Silverstack delivers top performance in terms of copy and verification speed and simultaneously extracts all file metadata for building a valuable clip library.

Major Camera Formats

RAW, 8K, or compressed – Silverstack offers support for all major camera formats and even can link the specific audio and look information to the corresponding clips.

Improve Collaboration

The ability to customize and share project metadata enables teams to complete all aspects of every production more quickly while reducing manual rework.

Maximum Control over Shooting Data

Source material is a highly valuable asset on set. In order to securely manage and control this material, Silverstack introduces a clearly structured process for handling source material throughout production.

Copy and Backup Your Data Securely.

Silverstack copies material using common and up to date checksum methods, making sure that footage is offloaded from cameras and backed up to multiple destinations in a highly secure way. For example, with Silverstack’s cascading copy function, backup your footage to the fastest medium first, before a second copy process is automatically started to the remaining drives. To be clear, this happens all while the same level of safety is retained.

Manage Data Transparently in One Place.

Silverstack automatically stores and structures all offloaded and ingested data in its central clip library. This library, the solid foundation for a clearly arranged and transparent data management workflow, keeps all digital assets organized in one place. In other words, assets are easy to find, trace, and mobilize all required clip, audio, and look information.

Silverstack + ShotHub

Benefit From Cloud-Powered Library Sync Across Units

Working with multiple units? Sync each unit’s local Silverstack clip library via Pomfort’s cloud service ShotHub to drastically accelerate your data handling.

Multiple Silverstack units offload and perform jobs in parallel, while all connected libraries get updated automatically, bi-directionally, and in real-time. The result: Seamless collaboration and complete data transparency across locations.

Extensive Reporting Capabilities

Summarize All Media Related Information and Share It with Your Team.

Documenting and sharing the results of all data management activities represents an important part of your everyday professional responsibility. With Silverstack, you can generate various report types such as shooting day reports, clip reports, thumbnail reports, or volume reports. With just a few clicks, easily tailor and customize the report to your production’s specific requirements.

Improved Collaboration on Set and Beyond

Easily Transfer Digital Assets and Share Information with Your Team.

Silverstack offers all the flexibility you need for your specific production workflows. The powerful integration with all common third-party tools like DaVinci Resolve, AVID Media Composer, and Adobe Premiere enables a seamless transfer of data and color for further review and processing. In addition, the opportunity to generate customizable clip reports with just a few clicks gives the entire production team a quick and detailed overview of all relevant production data.

On-set Quality Check of Source Material

Playback and Inspect Clips Natively to Detect Image Errors Instantly.

Silverstack enables you to detect image errors directly on set. To explain, this prevents costly surprises in post-production. Playback your clips natively in different resolutions. Optionally, monitor the image via HD-SDI to ensure that all material meets your quality expectations. Furthermore, check clipping, focus, and exposure with Silverstack’s visual controls. In addition, use Silverstack’s look management functionality for applying and adjusting colors.

Silverstack and Silverstack XT

Silverstack covers all functionality for comprehensive on-set data management. In addition, Silverstack XT extends these features by additional formats, distributed workflows, and specific post features.

Compatibility

Operating Systems

Our software Silverstack requires an Apple Mac machine with macOS 10.15 or higher operating system. Since we are using the latest of macOS technologies, we are not planning to support earlier versions of macOS, neither will we port Silverstack to another operating system in the near future.

Intel Mac, Apple Silicon M1 Mac (native) (For information on compatibility with the latest Apple Silicon computers please see our Knowledge Base.)
macOS 11.0 or newer

If your MacBook Pro is equipped with an ExpressCard/34-, CompactFlash- or SD card-slot, you can directly offload clips from any SxS, CompactFlash or SD card as they are used by following cameras: ARRI Alexa (SxS), RED and AJA Ki Pro (CompactFlash), Sony Sony F5 / F55, Canon EOS C300, Canon EOS DSLRs , Nikon DSLRs and GoPro (SD Card). Otherwise you need a suitable card reader.

You can find a list of supported formats in the article Assets in Silverstack. All formats with no specific detection will be handled as generic files. Please see the article Generic File Formats for more information.

For a realtime playback of your offloaded video files the usage of a fast hard drive as a SSD card is recommended.
