Using FlowCaster with Adobe (Premiere, After Effects)

FlowCaster SwirlFlowCaster creates a virtual I/O board as a transmitter for Adobe creative software like Premiere and After Effects.  As a virtual video board, it can send the same high quality audio, video and captions from a real or virtual machine to wherever you are doing your creative work for output on a 'third monitor'.  This article demonstrates configuring FlowCaster in Adobe creative software.

Sharing Amazon EFS Volumes To Windows

netxcode logosmallAmazon (as of 2023) does not have a direct driver for EFS volumes for Windows.  If you are using Net-X-Code in a cloud environment we recommend running the Linux version for direct access to the EFS volumes.  For other software [like Adobe/Avid]  that does not run on Linux, you can still access the files on the EFS volume by resharing the mount, internally or externally.  This article explains how to do that.

Controlling FlowCaster

FlowCaster SwirlFlowCaster creates a virtual I/O board for your creative software, desktop, SDI I/O board, or NDI source that sends a high quality video signal through the network for display on a local monitor.  This article covers controlling and configuring FlowCaster through command line, its settings, and via remote control.

DTMediaRead Pipe Utility

dt logo 1.5inchThe DTMediaRead SDK includes a utility called dtmrpipe. This utility allows the user to 'pipe' out uncompressed YUV2 or BGRA video data to another application. It can also be used to pipe an uncompressed stereo audio stream in 16 or 32 bit little endian. This is useful for feeding other applications, such as ffmpeg, with the output of file formats, types or codecs it doesn't support.

ProRes Color Shifts In Post Production

prores chipProRes itself is very well defined, and should be completely gamma/color shift free in the YCbCr domain at 10 bits per component.  The transform to YCbCr from RGB can be specified within the compressed frame, and this same specification can be used to properly convert YCbCr to RGB.  With both 4:2:2 and 4:4:4 variants and the metadata/compatibility of the MOV container, ProRes should be an ideal format for post production.  This article explores why it often isn't.

4KScope/HDRScope Multiple Inputs

4k 1004KScope, HDRScope, and 2110Scope have the ability to use multiple inputs as individual inputs for some video capture boards (like AJA, Bluefish444, and some Blackmagic boards).  When setting it up this way, you will lose the ability to do multi cable input for dual link, QHD/4K and other modes.  Each input will be limited to one BNC.  This setup can be easily reverted when not needed.

MediaReactor Usage Tips

mediareactor logo smallMediaReactor software integrates tightly with installed operating systems and applications.  This section has tips and tricks on getting the most out of MediaReactor Lite and/or MediaReactor Workstation.

HDR 10 Bit / 12 Bit Support For HDRScope

4k 100HDRScope supports 8, 10, and 12 bit SDI inputs.  This article maintains a list of compatible hardware for 10 and 12 bit 4:4:4 RGB signals.  Please note, if the board is not on this list, it is likely limited to 8 or 10 bit YCbCr inputs. 10 and 12 bit 4:4:4 require direct SDK access to the board, and are therefore only available on AJA, Bluefish444, Blackmagic, and specific Matrox (OEM) boards.

Advanced Hardware Keyer Usage

vidhw chipAJA video boards generally include a Mixer Keyer element.  Drastic software does not directly control the Mixer Keyer, but are designed to allow the user to use the Mixer Keyer alongside the main software.

Avid AMA Linking and Audio

Avid Media Composer 6MediaReactor Workstation and MediaReactor Lite add support for a wide variety of file formats to Avid Media Composer, including HEVC, AS-02, IMF, DNG, VRAW, CDX, YUV, and many more.  These files can include a mix of audio rates (normally 44.1, 48 or 96 kHz), and Media Composer requires some setup to allow them to be used in a standard project.  

Single/Dual Link Input Problems

io chipConnecting single and dual link inputs incorrectly can cause odd looking signals.  Here are each of the incorrect paths shown as they would be with a standard SMPTE bars input.

Setting up debug logging

dt logo 1.5inchDrastic software outputs a lot of information when running.  Working with our APIs and command line tools, having the debug logging can help sort out interface and programming issues.  Storing these logs locally, off via a syslog server, can also help sort out issues by comparing the unexpected behavior to the corresponding time in the logs.

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, Net-X-Code Server, MediaReactor and other Drastic products.

Autodesk Creative Raw Ingest

Autodesk's creative software, Flame/Flare/Smoke/Lustre, support MediaReactor's file import 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 bit 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 videoQC, 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

dt logo 1.5inchNet-X-Code Server supports loop recording of multiple bitrate HLS (HTTP Live Streaming) streams from IP or SDI sources.  Setting this up requires configuration of the capture component and HLS adaptive bitrate settings.  This article covers the SDI and IP capture.  For the ABR setup, see


dt logo 1.5inchDrastic software can read many file formats which it does not natively understand.  Formats that have a fixed video frame size and are logically organized can be described using the industry standard HDR text file format (NOTE:  Not the still image HDR).  This page describes the file format. 

Multirate HLS and DASH Setup

dt logo 1.5inchDrastic conversion and capture software support single rate and multirate file recording and conversion.  Up to 10 different bitrate/fps/size variants are supported per multirate output.  The actual files may be TS, MP4 or DASH/Fragmented MP4 with associated MDP and HLS files for live replay of recording files, and automatic adaptation to varying connection conditions.
