videoQC/4KScope macOS Validation

MacOSX UniversalApple's High Sierra operating system has changed the validation system, especially for applications downloaded from the internet. This has caused some systems to go into a 'validation loop' that stops our videoQC and 4KScope software from running, as the Apple validation never completes.  We are working on fixing this, but in the meantime, there is a way to stop the validation so our software can run.

Animation And Single Frame Recording

dt logo 1.5inchNote: This area describes legacy products. Drastic VVW and Titan Series DDRs, QuickClip, MediaNXS and DrasticDDR software can be used to capture single or multiple frames into a sequence of still images which can be played back in real time immediately after recording. These still image files can be stored into individual, time based directories, or into a single directory.

ccEmbed - Embed Captions MXF/MOV

verifycc icon

ccEmbed is part of ccConvert and Net-X-Code Server software. It is designed to take MCC or SCC closed caption files and embed them into output MXF, MOV, etc.  It supports re-wrapping the source audio/video, as well as converting while embedding.  This article contains the Linux/macOS/Windows command line API for this tool.  A RESTful API is also available.

Up And Down Converter Setup

updown chipOn supported hardware, Drastic software provides control of any up or down video conversion.  This can be set up in real time from the QuickClipXO, MediaNXS, VTRIF, DTReplay or dTouch interfaces.  The parameters and advanced settings in the configurations are provided below.

Using IP Video Streaming

dt logo 1.5inchDrastic software supports a number of IP video standards in videoQC, Net-X-Code, FlowCaster and other products.  To access these streams, a URL style string is used to describe them.  For some sources, like RTSP, this string is fairly standard.  For others, like NDI, a URL style has been developed to allow those streams to be specified.  Currently, udp://, rtp://, srt://, rtsp://, ndi://, s2022:// and s2110:// are supported.  This document describes the URLs' format in more detail.  We have also added some application specific notes for connecting our software to other applications.

Multi Channel Audio In Drastic Software

dt logo 1.5inchDrastic software can support up to 16 channels of audio.  These can be 16 mono channels,  8 stereo pairs or all channels in one, depending on the setup and file type. This article covers the kinds of audio that the software can produce, and the audio setups it is able to read automatically to combine multiple channels of audio with video. 

4KScope AJA Shared Mode

dt logo 1.5inch4KScope can be set up to share an AJA board with products like Adobe Premiere, Avid Media Composer, Assimilate SCRATCH, Autodesk Flame, Digital Vision Nucoda, Grass Valley Edius, and others.  This mode is available on Windows, macOS and Linux. This article explains how it works and how it can be set up.

Front Panel Controllers

fpc chipDrastic server software supports different front panel options:  The original 422 Jog/shuttle, the 4 line LCD with command keys and the newest touch screen VGAs.  This page describes the configuration for these front panels.

OpenMXF support

dt logo 1.5inchDrastic software supports the OpenMXF specification extension to the SMPTE MXF specification (SMPTE 377M). The advantage of OpenMXF is that while the file is still recording (open) you can read it in many popular servers and editing applications.

Keyboard Layout for Drastic Programs

kbd chipAll Drastic software uses a similar keyboard layout for control.  There are some variations for program-specific functions, but the general transport control is shared.  Currently supported software includes:

MediaNXS, videoQC, sdiScope, 4KScope, HDRScope, Network Video Analyzer

Controlling videoQC

videoqc logo 3smallvideoQC can be called by external applications with command line parameters, keyboard/mouse, cut/paste and via a full REST/HTML command set. If there is already an instance of the application running, the parameters will be transferred to the running instance, and the called one will exit.  This is especially useful where the workflow requires the system to display particular aspects of a clip in an automated fashion.

Drastic YCbCr Codec for Windows

dt logo 1.5inchDeprecated:  The Drastic Technologies YCbCr codec for QuickTime, Video For Windows (VFW/ICM) and Direct Show allows third party applications to use files (AVI and MOV primarily) generated by VVW, Titan Series, QuickClip and MediaReactor.  Please note, this codec has been deprecated.  The new codecs are available as part of the MediaReactor Workstation.  The original codec with updated installers is still available here.

Setting up Amazon S3 AWS Access

dt logo 1.5inchAll of Drastic's version 6 or greater software supports authenticating directly with Amazon via AWSAccessKeyId/SecretKey through an https transport. This is most useful for Net-X-Code's partial file restore system, but can also be used from videoQC, MediaNXS or MediaReactor.  Accessing these resources requires a second level of setup, beyond the basic software setup, and this article provides an overview on that process.

FileBrowse Parameters

dt logo 1.5inchDrastic server software includes an HTTP server for local or remote control / access from a standard web browser. One of the files, FileBrowse.html, allows for file selection from selected drives using the web browser. Depending on the command line, FileBrowse can be used to save, load, add, or open files without direct access to the file system.

Setting up Google Cloud (OAuth 2.0) Access

dt logo 1.5inchAll of Drastic's version 6 or greater software supports authenticating via OAuth 2.0 across an https transport. This is most useful for Net-X-Code's partial file restore system, but can also be used from videoQC or MediaReactor.  Accessing these resources requires a second level of setup beyond the basic software setup, and this article provides an overview on that process.

Java on Dual Monitors

dt logo 1.5inchJava on Dual Monitors - NVidia vs. Java.  There are setups required on some systems to allow QuickClipXO and VTRIF to display full screen on the second DVI or VGA monitor.

Running videoQC, 4KScope & Apps Remotely

4k 1004KScope, videoQC, DrasticPreview, DrasticPreview Pro, and other OpenGL based apps can have trouble displaying the video in an OpenGL plane when connected via Remote Desktop Protocol or other remote control protocols.  To fix this problem, we supply special start files to be used remotely.
