Daily Activation in Pomfort Account

Daily License Activation Mode

New Day, Different Machine.

The optional “daily license activation mode” allows to use your Silverstack license on different machines on different days.

Have you ever forgotten to deactivate your Silverstack license before switching machines? In the Pomfort account, you can set your license to the new daily activation mode. This will automatically release the license on your computer after each shooting day. Starting the next day on a different or the same machine, you can conveniently activate the license on the exact system you need today. Activating the license at the beginning of a shooting day requires an internet connection, so don’t forget to switch back to the “Standard Activation Mode” in your Pomfort account before moving to the desert…

ASC MHL For Offload and Backup

Create and Continue Hash Manifest Histories.

Silverstack 8.4 comes with support for creating and managing hash manifest files of the new ASC MHL standard.

The offload wizard indicates if the source volume contains an existing ASC MHL history and checks if any files are missing. If an ASC MHL history is found on the source, the history is continued on the destination volume (if possible). Cascading copy creates a first generation on the first run’s destination and an additional second generation on the second run’s destination. Together with ASC MHL, Silverstack introduces new checksum methods, like C4ID, XXH3, and XXH128, for even more flexibility to ensure file integrity in your data management workflows.

ACES Look Exchange:

  • AMF Import: Import ACES Metadata Files (AMF) including Common LUT Format files (CLF) used in LMT nodes and exchange with third-party applications

Usability Improvements:

  • Summary of Jobs per Volume: Check the states of all jobs that require a specific volume in the offload menu
  • Improved Search & Filter: Use related search keywords to retrieve metadata fields in the general info tab or the table column selection menu (e.g., find “Tint” also when searching for “White Balance”)
  • Retrieve Column in Main Table: Added “scroll to column” button in table column selection menu

Volume Info:

  • Volume Last Seen Info: Shows in volume view which user was the last one to have a drive connected and when (only when the clip library is synced with ShotHub)

Offload Menu With Job Status

Offload Menu With Job Status

Summary of Unread Jobs per Volume.

The enhanced offload menu UI shows a summary of the jobs for each volume (running/queued: blue, failed: red, canceled: grey, completed successfully: green).

This summary allows you to identify easily which volume is ready to be ejected and passed on, even when many drives/cards/mags are connected and multiple jobs are running simultaneously. To prevent "old stuff" from distracting you, jobs marked as "read" are not shown in the new UI.

Activate the new UI in the general preferences.

Offload wizard templates already allow you to save and restore frequently used offload configurations, such as destination paths, file renaming patterns, or verification settings. You can now associate the templates with an input device (e.g. ARRI Alexa, GoPro Hero, Audio). The offload wizard will then automatically pre-select the appropriate configuration for the input type you are about to offload. One thing less to worry about.

Performance Boosts

Performance Boosts

Get the Best Out of Your Hardware.

With Silverstack, decoding and encoding performance of popular codecs improve significantly. Even more steps are now parallelized or boosted by hardware acceleration. All codecs are processed natively on Apple Silicon (M1, M1 Pro/Max) systems, and custom default settings for different hardware setups will give you the best performance on your machine. You will see faster processing of ARRIRAW and Canon Cinema RAW footage on most systems. The latest Apple Silicon machines will also show better hardware acceleration for ProRes and RED footage out of the box.

Library Sync and ShotID

Library Sync and ShotID

Connect to the Cloud for Streamlined Workflows.

Through ShotHub, you can now merge the separate clip libraries of each unit's Silverstack application into one shared project. When internet connection is available, the changes on one computer’s library are synced to all other computers, so everybody can add and check the latest project progress. Split your workflows to multiple machines accessing the same clip library.

Need to share with non-Silverstack users? Simply forward the clip's 9-digit ShotID or burn a QR code into your transcode and invited users have easy access to the clip's metadata on ShotHub via web browser.
