It is possible to modify Silverstack’s behaviour concerning multiple tasks in the application preferences, as described in the article “ Tweaking copy performance“. The articles “ Factors for data-transfer performance” and “ Analyzing and improving data-transfer performance” explain in detail all the improvements and hardware specifications that can modify the copy process performance. Image transformations will be also applied if you decide to transcode the clips. This features are helpful to check the quality of the clips without distortions. Store all clip, look, and audio information, as well as transcodes, in Silverstack Lab’s library. The ability to de-squeeze footage recorded with anamorphic lenses and image flipping is available in Silverstack. Various configuration options, such as frame lines, metadata burn-ins, and watermarks. ![]() Transcode to multiple formats and resolutions at the same time. The slowest of the components will define the system’s final speed. High speed transcoding to Avid DNxHD/DNxHR, ProRes, and H.264/H.265. The maximum copy speed, that Silverstack performs, is determined by the hardware setup you are using. You can skip the verify process in the Offload and Backup wizards, but we strongly advise to use verification in a real production scenario. This process ensures that the files you have copied are exactly the same as in the source. The “Combined Speed” as shown in Silverstack’s job view by default may be lower than the maximum transfer rates (or the rates that can be seen when copying with Finder) due to the additional verification process. ![]() You can monitor the transfer rates in Silverstack’s job view and in macOS’s Activity Monitor application.įigure 2: Writing speed (red) and reading speed (green) during Copy and Verify phase. Silverstack 8.0 introduced a file renaming option in the offload wizard that provides a transparent and easy solution for these scenarios. The writing speed drops to zero and the reading speed increases, as Silverstack is reading all files again from the copy destinations as well as from the source (see Figure 2). When the Copy phase is finished, the file verification takes place. In the Copy phase the reading speed from the source and the writing speed to each destination is the same. Figure 1 illustrates these two phases:įigure 1: The two phases of the copy process The copy process is split into two phases: The “Copy” phase and the “Verify” phase. This means that you can copy media files from camera media to different external volumes with a verification process that ensures the completeness and integrity of your files on each destination. 99 of the time you’ll be fine but I’ve definitely had instances where the main copy was corrupt but the backup copy was fine. The only issue that I have with cascading copy is that you’re not pulling from the SOURCE for the additional copies. ![]() One of Silverstack’s key features is the fast, checksum-verified backup to multiple destinations. You can do cascading copy if you have a fast raid, such as a SSD, if you’re doing transcodes.
