Pomfort Silverstack Lab

Data Management and Dailies in One

Silverstack Lab is the first software that enables a simultaneous handling of data management and dailies creation in one tool. By integrating the renowned data management capabilities of Silverstack with an elaborate set of functionalities needed for a lean and highly efficient dailies creation process, two previously separate production steps are merged into one integrated activity. Footage can be backed up securely and organized transparently, while at the same time dailies can be created.


The core of Silverstack Lab is its central clip library. From the first moment media is loaded off the camera, Silverstack Lab automatically stores all clip, look and audio related information in its central library. When transcoded clips are created the library also tracks and logs all essential clip information. Having all digital assets in one place makes it easier and faster to manage, control and exchange production critical data.

On top of that, Silverstack Lab comes with a high performance transcoding engine and an automated audio sync function that significantly accelerates the creation of dailies. By supporting the simultaneous transcoding to AVID DNxHD, ProRes, and H.264 file formats and parallely to various resolutions, dailies creation reaches a whole new level of productivity. With Silverstack Lab, film productions benefit from an intelligent, streamlined and self-contained data management and dailies creation process. The responsibility for this process can be assigned to one person in charge working directly on set.

1. Simultaneous handling of data and dailies in one integrated activity

By merging data management and dailies creation into one integrated activity, a seamless workflow with less interfaces, a reduced overall complexity and a lower risk of costly errors is enabled. Silverstack Lab provides a clear structure and secure processes that enable direct control over footage and immediate access to transcoded clips

2. Rapid transcoding with hybrid CPU / GPU-based transcoding engine

Silverstack Lab’s highly competitive transcoding engine allows a simultaneous transcoding to various resolutions and to all required output formats like Avid DNxHD, ProRes, and H.264. Silverstack Lab comes with all the power and capabilities needed to rapidly transcode clips for editing systems, web platforms, and storage archives.

3. Automated syncing of video and audio

Silverstack Lab offers a fully automated audio sync functionality. The incorporated syncing wizard detects corresponding audio and video clips based on time code and automatically syncs them. This way, users have to spend less time on manual preparation work, and more time on the creation, management and delivery of digital assets.


Audio Clips

Manage and Sync Sound Files.

Silverstack Lab reads extended metadata from BWAV files and other audio formats, and automatically groups together track files that belong to one clip. You can automatically match and sync audio and video clips by timecode information, and it's also possible to manually sync audio and video by setting slate markers.

Silverstack Lab supports playback multi-track audio and video clips (solo and grouped). Individually adjust level and panning of internal and external audio tracks for the stereo-mixdown used in rushes and dailies.

Dailies Creation

Create Native Avid DNxHD/MXF, Apple ProRes, and H.264 Files for Editorial and Review.

Silverstack Lab's hybrid GPU/CPU-based transcoding engine reaches impressive speeds (e.g. by utilizing multithreading and multiple GPUs), that makes it possible to transcode multiple dailies deliverables at the same time on a single Mac notebook fast enough to cover the dailies process for an entire shooting day.

Silverstack Lab adds new features such as various burn-in options, watermarks, and frameline overlays for your production's specific needs. You can also create clips with multiple original audio tracks.

All transcoded clips are managed in Silverstack's library and are part of the workflow statistics, that help you get a quick overview of the status of your day's work.

Examples of Transcoding Speed

New MacBook Pro (15”, Late 2016) with Silverstack Lab
 2.6 GHz Intel Core i7 (AMD Radeon Pro 450):

silverstack lab transcoding speed


ARRIRAW in Open Gate, 3414x2198 resolution and debayered in half-res quality. H.264 is in 720p resolution, ProRes 422 LT is in 1080p resolution. No look and overlay is applied.

The hardware setup needs fast disk I/O (e.g. a SSD RAID). The ARRIRAW transcoding example requires roughly 720 MB/sec read speed to encode ARRIRAW material to DNxHD 155 and H.264 in 21 minutes (1h of ARRIRAW at 24 fps has a size of approx. 996 GB). The transcoding speed is equivalent to 62 frames/sec decoding speed for the ARRIRAW material and 124 frames/sec encoding speed for the simultaneous creation of DNxHD and H.264.

* Multiple formats are transcoded simultaneously

Supporting Post-Production Workflows

Fine-Tuning for Metadata Transfers.

The process of creating dailies has to have the overall workflow in mind – from editorial to conform and finishing. Therefore Silverstack Lab let's you fine-tune the metadata that goes into and travels with the dailies. Depending on the chosen destination application (such as Avid Media Composer, Final Cut Pro X, Adobe Premiere, or DaVinci Resolve) you can set for example the type of clip and "tape" names in such detail, that no workflow will be left behind. In Silverstack Lab's transcoding configurations you can set which and how metadata files should be automatically created after finishing the transcoding jobs.

Tons of Improvements

Window Configurations and Multi-Clip Grid View.

Silverstack comes with easy access to different window configurations, that are tailored to specific activities on set, such as management, QC, color grading, or configuring the transcoding process. Window configurations get all the user interface elements out of the way that are not needed at the moment and puts the focus on the user's current task with just one click.

Silverstack Lab allows to place user interface elements such as a clip collection on a second display. For improved look management and QC, Silverstack Lab offers a side-by-side mode of the player, that can display up to twelve clips simultaneously – either on the computer display or on the HD-SDI output.


Operating Systems

  • Intel Mac
  • OSX 10.12 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.
