Dante Virtual Soundcard uses your computer’s Ethernet port to communicate with other Dante-enabled devices on the network. ## Product Page https://www.audinate.com/products/software/dante-virtual-soundcard ## 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) # OBS Studio # OBS Studio # Open Broadcaster Software (OBS Studio) OBS is a free and open source software for Windows, macOS and Linux with video recording and live streaming functionality. ## Download https://obsproject.com [Previous Software Releases](https://github.com/obsproject/obs-studio/releases) ## Discord https://obsproject.com/discord # Bitfocus # Bitfocus Companion ## Bitfocus Companion Works with or without [Elgato Streamdeck,](/link/100) includes web based Streamdeck emulator.

See [ProPresenter 6 End of Life FAQs](https://support.renewedvision.com/hc/en-us/articles/10589582923027-ProPresenter6-End-of-Life-Frequently-Asked-Questions) 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. ## Configuration and Media Transfer Below are the files that need to be transferred to copy a machine's configuration over to another Mac.

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](https://github.com/greyshirtguy/ProPresenter7-Proto) to create/decode the buffers.

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](#different-editions-avenue-vs-arena) 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 For a complete (and up to date) list of differeneces, see [Differences between Avenue and Arena](https://resolume.com/support/en/avenue-arena-difference). # Resolume Wire # Resolume Wire # 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. # Term Explanations ## Traffic Shaping - Senders/receivers - Wide, narrow - Synchronous, Asynchronous ## Hitless merges ## NMOS ## IS-04 Registration - mDNS/DNS-SD ## IS-05 Connection management ## IGMP v2 vs v3 ## PTP v2 ## Multicast ## Audio Conformance Levels https://www.ravenna-network.com/smpte-st-2110-and-audio/ ## 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. https://docs.ruckuswireless.com/fastiron/08.0.60/fastiron-08060-ipmulticastguide/GUID-90A4D045-734C-4CAD-A0D0-59A7C40FB83E.html # FFmpeg FFmpeg Landing page FFmpeg Home Page: [https://ffmpeg.org](https://ffmpeg.org) Useful Commands: [/en/software/ffmpeg/ffmpeg-commands](https://videng.wiki/link/131)
