Dante Virtual Soundcard

Dante Virtual Soundcard is a simple, easy-to-use software application that turns a Windows or Mac computer into a Dante-enabled device, enabling you to instantly connect to any Dante network. Dante Virtual Soundcard uses your computer’s Ethernet port to communicate with other Dante-enabled devices on the network.

Product Page

Download

https://my.audinate.com/support/downloads/dante-virtual-soundcard

Activation

Each Dante Virtual Soundcard license can be activated four times before you receive the error “The license has been activated too many times” preventing further activiations. {.is-info}

Networking

Dante Virtual Soundcard only works on untagged VLANs. If your network interfaces has multiple VLANs trunked, Dante Virtual Soundcard will only communicate on the untagged VLAN.

IGMP Snooping Forwards All on macOS

macOS machines running Dante Virtual Soundcard will likely lose clock-sync and mute when IGMP Snooping is engaged on many switch manufacturers. The macOS and many switch configurations do not refresh the Time-To-Live for multicast subscriptions, and thus the clock falls silent. You’ll know this is the case if Dante Controller shows “Listening” status. To address this manually forward multicast traffic to the ports the Mac is using. Related to https://serverfault.com/questions/819793/os-x-network-stack-ignores-igmp-membership-queries

10Gb Ethernet on macOS

Dante Virtual Soundcard (transmission) does not work on any 10Gb ethernet ports on macOS. You'll have to use a Thunderbolt to 1Gb Ethernet adaptor if you're using a machine that has a 10Gb ethernet port. http://duc.avid.com/showthread.php?t=410371 The reason for this is the 10Gbps Ethernet port on macOS does not support PtP (Dante Clock) correctly, rendering it useless for Dante. This is an Apple hardware/driver issue which also impacts other protocols that need PtP clocking, and with nothing Audinate can do to fix it. (According to Audinate, Apple fixed this issue in macOS 12 Monterey)

Renewed Vision

ProPresenter 6

ProPresenter has announced effective January 31, 2023, ProPresenter 6 will be no longer supported or updated and the ProPresenter 7 upgrade discount will no longer be available. See ProPresenter 6 End of Life FAQs for more information. {.is-warning}

Tips and Tricks

Changing Underline Font Color

Sometimes ProPresenter will do funky things when setting a highlighted portion of text that includes an underline. When this occurs, ProPresenter will display an underline that is not the same color as the text highlighted. To fix this, you must manually set the underline color in the Text Style dialog.

Edit the slide, and go to the Text Properties tab. Click the 'Edit Text Style' option. (The button with an 'A' on it), then from the underline option select color and set the underline color.

Managing Media Automatically.

ProPresenter by default is set to manage media automatically. This means ProPresenter will copy all media imported into ProPresenter in a folder (called 'Renewed Vision') and will sort the media into subfolders so the application knows where each file is. This is very helpful if you are importing things from external drives, or don't want to physically manage media locations manually.

File Format

Presentations created in ProPresenter are saved with a .pro file extension. Prior to ProPresenter 7 files included the version number in the extension, for example .pro6, .pro5 letting you know which version the presentation was created in.

ProPresenter 7 files are no longer XML formatted, instead they are using Google Protocol Buffers, meaning you need this library to create/decode the buffers. (Read more here, or here, or here)

Resolume

Resolume Avenue/Arena

Resolume Arena is a software application (for Windows and macOS) enabling real-time video and audio playback, manipulation, and effects processing. It is commonly used in live events, AV productions, concerts, corporate events and more.

Resloume allows users to map video content to various surfaces and shapes, such as flat screens, projections, and 3D objects. This can be done using a variety of mapping tools and techniques, including corner pinning, edge blending, and surface deformation.

Resolume Arena also allows users to play out video content in a variety of ways. They can choose to play video clips in sequence, play them randomly, or play them based on certain triggers or events. Users can also adjust the speed, looping, and direction of video playback, as well as apply various audio and video effects to the content.

In addition, Resolume Arena has a number of features that allow users to control and manipulate the playback of their video content in real-time. This includes the ability to use midi controllers, OSC (Open Sound Control) devices, and other hardware to control the playback of video clips and effects. Users can also use the software's built-in timeline editor to create more complex and synchronized video playback sequences.

Different Editions (Avenue vs Arena)

Resolume Arena has the following features that Resolume Avenue doesn't:

Projection Mapping
Edge Blending
SMPTE Timecode input
Denon StageLinq
DMX Control
DMX Fixture Output
Capture Card Output
Groups
Slice Transforms

2110 Basics

What is 2110?

2110 is a replacement for SDI that transports uncompressed video over IP networks.

Is it like NDI?

In that it is video over IP, yes, but in many ways no. 2110 is a SMPTE specification for uncompressed video, NDI is a proprietary protocol that compresses video. 2110 is designed for use with 10G network links or greater, whereas NDI must compress your video streams down to less than 1G of bandwidth.

SSM vs ASM

ASM stands for Any-Source Multicast, and SSM, the preferred option for 2110, stands for Source-specific Multicast. With ASM the multicast client doesn't know the multicast sender's unicast address (source), only the multicast group IP's address.

With SSM, the multicast client can specify which multicast sender's unicast address (source) in the multicast group it wants without having to discover them as it has to with ASM.
