Happy Holidays everyone!

We are excited to release our Beta build of Wirecast 15.0! Once again, we are breaking records: Wirecast 15 is the 2nd BIGGEST release we've ever had in terms of issues added and fixed. Below are some highlights of what's in this Beta. 

I once again humbly ask for your help! We want to hear what you think. Please install this in your environment and post your feedback - good and bad on the Beta Discussion Thread.

Below, are the full the release notes in case you really want to nerd out. There are also a few known issues listed at the end. 

As always, thank you!

  • New! Social Media Comment Moderation
    • Integrate Twitter, Facebook and YouTube comments directly into your broadcast.
    • See all comments from the supported connected platforms come into one Comment Moderation window. Add one of the new Social Media Titles from the add source menu, select a comment, and your comment will automatically display in your social media title. You can rotate selected comments automatically, or manually select your comments. We now also support YouTube Member Milestone Chat Messages and Twitter Post photos.
  • New! Major Performance Improvements
    • We've done a massive project to improve the efficiency of Wirecast on your hardware. (Benchmarks coming soon!) A few highlights include: more efficient GPU rendering with Direct3D12 on Windows and updated encoding presets for more efficient encoding without sacrificing quality. But there is much more under the hood! We'll be doing benchmarks, but would love to hear your anecdotal experience with this (on both Mac and Windows).
  • Improved! File playback performance
    • Alongside the general performance improvements, we have also specifically improved performance of file playback.
  • Improved! 4K support
    • Improved support for 4K60 input, playback and streaming. With all the work we've done improving performance and playback, one of the benefits is greatly improved handling of 4k content.
  • Improved! Web Page Source interaction
    • When you add a web page source to your document, you can now select a mode where you can interact with that webpage, as if you were in a browser - from directly in the Wirecast UI.
  • New! Refreshed UI
    • We've updated and refreshed the User Interface. Besides being a pleasing design, we now offer larger, brighter fonts, better tally indicators and more.
  • New! More Rendezvous Improvements
    • More layout options: We now let users choose either a grid layout for all guests or one-main-guest-others-small layout in their Rendezvous Dashboard
    • Mirror view: Ability for guests to mirror their self-view by clicking "Flip Video Horizontally"
    • Muted: Host can see when guest's mic is muted
    • Network Diagnostics: Rendezvous hosts can now see an icon (either a green, yellow or red signal icon) for each guest, indicating downlink network quality (from guest to Wirecast).
      • Additionally, the host can see current network stats in the left bottom corner of each guest's video. Presented stats are: received bitrate, round trip time, jitter and packet loss. Stats are refreshed every 5 seconds.
  • New! Rendezvous Music Mode
    • Rendezvous guests can turn on Music Mode, which will greatly improve the audio quality when playing musical instruments over Rendezvous
      • Details: Rendezvous guests will have the option to turn on Music Mode in their Rendezvous web app. This will:
        • 1. Enable stereo audio
        • 2. Increase the audio bitrate to 256k. (By default, it is mono 32k. When enabling music mode, it will be two channels, 128k each.)
          • Note: this applies only for RV guest sending audio to Wirecast. Higher quality audio will not be sent to other guests in session (bandwidth utilization would be significantly higher in such case).
        • 3. Disable audio processing (echo cancellation and noise reduction)
          • Note: disabling audio processing for normal microphones and just talking can result in poor quality audio - so this should only be used for playing instruments.
  • New! New and Improved Audio Meters
    • All audio meters now use a consistent dBFS scale across the app. You'll see consistent readings whether you're looking at Multiviewer audio bars or the Advanced audio Meter. Levels turn yellow when they hit -6dB and red anything greater than -1dB. All meters are consistent in showing when audio is clipping (yellow & red)
  • New! More Animated Titles
    • We continue to build our library of animated titles with several new options in addition to the new social media-specific titles
  • And more!
    • Improved the low-level clock system in Wirecast. This will improve A/V sync over long periods of time.
    • Improved quality of Screen Capture source on macOS Retina displays.
    • Improved the framerate of Multiviewer on Windows.
    • Improved workflow when deleting a source from the Asset Manager. It will now remove any layers of that source from the document.
    • Improved audio “smoothing” when a discontinuity occurs.

In addition to all the new & improved features, we have a significant amount of bug fixes. Here's just a highlight of a few:

  • Made some significant fixes around A/V sync issues
  • Support TLS 1.2 for web sockets on Windows
  • Fixed Elgato Facecam working on Wirecast Windows
  • Fixed Error Code -1 when starting Replay / ISO
  • Fixed a variety of hangs that could occur when trying to start/stop a problematic broadcast

    Rendezvous Music Mode!  So stoked to see this in the new version.  Let's hope it works.  I did notice on startup the Beta didn't detect the internet even-though internet was connected.  Tried three times and saw same message "Internet Not Available"
