Tips, tricks, FAQs and technical information for Drastic hardware and software products
This article lists the locations where Drastic software components may be installed, in case the software needs to be removed manually.
The Drastic EDL format uses the same basic layout as a CMX, GVG or Sony 91xx series EDL. The main differences are the 'Type:' header and the file name in the comment. The comment is broken up into two sections: The initial comment after the ';' and a file name after a second ';'. This page describes the exact format used.
Drastic 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.
The 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.
Drastic software supports a number of IP video standards in videoQC, Net-X-Code 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://, rtsp://, ndi://, s2022:// and s2110:// are supported. This document describes the URLs' format in more detail.
Drastic 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.
Apple'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.
DrasticPreview and DrasticPreview Pro can be called by external applications with command line parameters. 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.
Most operating systems are not set up out of the box to handle heavy multicast loads. With some, multicast reception is actually disabled. This article contains setup notes for the OS when using Net-X-Code, videoQC or 4kScope with network video sources.
The DTMediaRead SDK now 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.
Drastic products generally support closed captions. Video I/O products can capture and play back closed caption information. MediaReactor can convert closed caption formats along with the video and audio files. videoQC products can decode and display both 608 and 708 captions for preview and confidence monitoring. For some captions, default language/fonts can be set up, which are described here.
Deprecated: 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.
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.
The Drastic LOG format uses the same basic layout as a LOG/~ALG/~ALE. The main differences are the 'Type:' header and the file name in the comment. The comment is broken up into two sections: The initial comment after the ';' and a file name after a second ';'. This page describes the exact file format used for the Drastic log format.
MediaReactor includes tools it uses to automatically check QA translations using industry standard metrics. This tool, called MRAnalyze, can be used in conjunction with DrasticPreview Pro to provide both objective and subjective analysis of converted or recaptured video material. This article provides an overview on how these tools work and can be applied to various video workflows.
