Benefit from Silverstack

Superfast and simultaneous. Automatically backup, structure and manage your movie data with 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.

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.

silverstack backup 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. With Silverstack’s cascading copy function, you can even backup your footage to the fastest medium first, before a second copy process is automatically started to the remaining drives – all while the same level of safety is retained.


silverstack manage dataManage Data Transparently in One Place.

Silverstack automatically stores and structures all offloaded and ingested data in its central clip library. This library is the solid foundation for a clearly arranged and transparent data management workflow. Having all digital assets organized in one place makes it 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 can 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

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
  • OSX 10.15 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.
