Drastic DT3D Stereo File

dt logo 1.5inchThe Drastic DT3D stereo file is an XML based re-director file that can merge two separate 'eye' files into a stereo pair, as well as adding audio and optional closed captioning. The stereo file reader will open two video files of the same file type, and internal compression type, and an optional set of audio files, and combine them for 3D use in videoQC, DrasticDDR, MediaNXS, MediaReactor and other Drastic products.

Autodesk Creative Raw Ingest

Autodesk's creative software, Flame/Flare/Smoke/Lustre, support MediaReactor's file ingest so that the wide array of Drastic supported files can be read and used directly in your projects.  Autodesk supports two modes of import:  16 bit half float and 16 integer.  Each has its advantages and disadvantages, which will be discussed here.

RS-422 Device and Controller Hardware

rs422 chipDrastic Technologies' VTR and DDR products include the necessary conversion hardware for RS-232 (your computer's serial port) to RS-422 (broadcast VTRs and controllers).  If you are evaluating Drastic DDR software such as MediaNXS, you will need to set up this conversion to test the serial control capabilities of the system. 

Running Net-X-Code (no server)

dt logo 1.5inchNet-X-Code is normally run on a server, where the parts of Net-X-Code run automatically as services. For some applications, only part of Net-X-Code needs to be run, or it only needs to be run some of the time. This article explains how to set up Net-X-Code server on Windows so that its parts can be run manually.

RS-422 Splitter Cable

rs422 chipWhen working with RS-422 protocols (Sony 422, Odetics, Pioneer, VDCP, etc) it is often useful to directly monitor the incoming, return or both serial streams.  This is a cable that can be built to use two RS-422 ports to monitor one or both streams. 

Loop HLS Recording SDI/IP
