Open Source Add Ons

Drastic Technologies software does not contain any open source software, but can and does make use of some open source software to enhance its operation and add features such as WebM, Mkv, DNxHD, ProRes, and AVCi. For most products, this requires a separate install provided below, but for non encoding products like DrasticPreview and DrasticPreview Pro, LGPL DLLs are also included in the installer. In either case, full source for the modules is provided here. These open source software packages are used and tested by Drastic Technologies, but cannot be directly supported as Drastic software. Users interested in enhanced versions of the LGPL modules are welcome to build their own and replace the shipped binaries, per LGPL.
These packages can be used with MediaReactor, MediaReactor Workstation, MediaNXS and DrasticDDR.

Extended Processor Support

Drastic Technologies uses enhanced intel primitives to build some of its codec and processing code. All the modern processor libraries are shipped with MediaReactor, MediaNXS, DrasticDDR and our other software. Most Drastic Technologies software can also run on older processors, but to get the best performance you will need to add the processor specific primitive libraries. Installers are available for Drastic Technologies' supported production platforms.
