The Drastic Test Pattern Generator can be used in conjunction with an install of HDRScope to provide a full featured audio video synchronization test. Test Pattern Generator sends a motion audio video sync pattern out and HDRScope receives the pattern along with its QR code and other details, and features an A/V Sync display that provides details on audio and video sync, and time in transit. Here is how to set up AV Sync testing.

When FlowCaster is installed in a DaVinci Resolve system, it adds a FlowCaster virtual SDI component that lets you send the output of Resolve via FlowCaster. This means you can output your timeline in any of the IP stream types supported by FlowCaster, including SRT, UDP, RTP, WebRTC, NDI, and ST-2110.

DrasticScope and FlowCaster support the AvVr3D ScopeDirect plugin for UnReal Engine, for virtual reality scene camera analysis and calibration. Select the plugin to send high quality audio and video directly to our waveform/vectorscope software for analysis, and to FlowCaster for remote sharing. Here is how to set up the plugin.

In Avid, scrubbing through the timeline is video-only by default, in order to provide faster, smoother operation. However, if you are using the FlowCaster OpenIO plugin to share the output of Media Composer, there will be cases where you will want to send the audio as well. Audio scrub can be enabled using a couple of methods, either temporarily, or as a setting that can be left enabled.

ST2110 is a family of standards for audio/video/data over IP format, that can clock to PTP and carry as many embedded essences as your network can handle. Drastic supports ST-2110 as an input for viewing and ingest, and as an output for distribution and delivery. This pages provides an overview of our ST-2110 related products, and offers information on ST-2110 in general.

The Drastic ScopeDirect Plugin is designed to be installed in a system with Adobe, Avid, OpenFX, Resolve, or UnReal Engine software. It will look at the video, audio, and ancillary data playing in the editor, and provide a range of waveform/vectorscope tools for setup, measurement, and calibration of levels.

In addition to an unparalleled range of vectorscope/waveform tools, 4KScope, HDRScope, and NetXScope also feature advanced multichannel audio meters, loudness meters, and surround sound audio monitoring and analysis. This article provides details.

If you want to run APIs or WebRTC connections externally, you can configure Apache to act as a reverse proxy using HTTPS on an external port (like 5000). and forward that traffic to an internal HTTP service running on a different port (like 15000). Here’s how to do it step by step:

Using FlowCaster with the www.flowcaster.live site may require some setup for your corporate firewall.  This is especially true if your system is running in a cloud environment like Amazon, Google or Azure.  By default these, and many other environments, completely lock down the internet access.  To use www.flowcaster.live, some standard ports must be opened up. 

Different IP video protocols require different firewall setups.  This article covers the most common ports / firewall access that different IP video protocols require.  

Asynchronous review lets anyone open a www.flowcaster.live session and add feedack via text, telestration, and emoji, and save the session to send off to the next stage of production.  It is similar to synchronous review, but only requires one person at a time, and may be done by each participant at any time.

The synchronous collaborative review workflow lets an operator select a proxy file/timeline from any network storage that is available to all participants and share it with a group of participants so their input and feedback can be saved for later review and implementation.

FlowCaster Live Event Review captures SDI or IP signals simultaneously as high quality MXF files and as time code matched proxy MP4s. This way the creative team can get started working right away with the proxy MP4s from anywhere in the world, and use the decisions to create deliverable assets as the stream is being captured.

One of the file format plugins (dtx_aWMFDirect.d1x) for Windows 32 and 64 relies on Microsoft Windows' media components.  With some versions of Windows, Microsoft does not include these components by default.  To fix this error, you can either delete the dtx_aWMFDirect.d1x and dt_WinMedia.d1x from the installation folder, which will disable WMV/ASF read/write, or install the missing components from Microsoft.  

Drastic signal analysis products support both command line parameters and keyboard control.  This command line parameters can be used to allow them to open automatically on startup in the mode and size required. The keyboard commands can be used to capture compressed and uncompressed frames directly from the incoming signal.

When using Media File Scanner, many sources will have directories and file names that exceed Windows' 260 character default limit.  If you are targetting an NTFS, or other Windows drive, you will need to enable long directory and file name paths in the Windows permissions.  This limit is to preserve compatibility with older, and MS-DOS, programs.  If you need that compatibility, you may want to target a NAS as the Media File Scanner output, which will support long directory/file names natively.

When using Drastic software on Windows, for some operations system settings must be altered to allow for the performance necessary for the workflow. This includes Net-X-Code Server, videoQC, sdiScope, 4KScope, HDRScope, FlowCaster and NetXScope.  By default, Windows is designed for multiple, low performance loads and UI experience.  The suggested changes allow Drastic software to get the required resources and performance required for consistent operation.

Avid tools support MPEG-4 using QuickTime as well as using MediaReactor Workstation. QuickTime cannot handle newer MP4 formats like XAVC-S and MPEG-2 from Sony and other manufacturers' cameras.
