Wirecast 14.0

Wirecast 14 is an epic release with a LOT of stability and reliability improvements. Additionally, we have several new features including an all new Chroma Key with added Luma Key and Color Key options.  

We’ve also focused on improving the experience of doing remote guest interviews by improving Rendezvous’ stability as well as adding more flexibility for what displays if your guest gets disconnected. 

Here's what to expect in Wirecast 14:

• All new Chroma Key (with special guests Luma Key and Color Key) 
  • New options for more accurate keying, including spill suppression, edge coloring, and clipping ranges. Plus a Luma Key (useful if you have a logo with a white or black background you wish to remove), and Color key (useful for images (logos) that have non-black and non-white backgrounds).  
• Better, more reliable incoming video source connections
  • Improved reliability for Wirecast Go, Rendezvous and webstream sources, plus efficiency improvements with GPU decoding for NDI sources  
• Text and font improvements
  • Smoother text scrolling and a new font picker to select font variants  
• More options when sources get disconnected 
  • When a source gets disconnected, you can now choose to replace it with transparency or a custom image 
• Improved ability to size and scale sources
  • We’ve added new options for sizing and scaling sources, making it easier to precisely size your videos and images on the canvas. Plus, incoming sources are now scaled automatically, and will maintain their size based on settings you choose.  
• Latency and syncing improvements 
  • We’ve made improvements to – and we've also given you more control over – the way incoming audio and video are synced together, ensuring more accurate lip-sync.  
• Updated technologies
  • Updated to NDI 4.5, ported OpenGL to Metal on macOS, updated webstream plugin (libVLC), for improved connectivity and efficiency 
• Better notifications and stats
  • The status bar is now moved to the bottom of the screen, giving more space to show System CPU and App CPU, as well as other streaming stats. 
• New, improved Multiviewer
  • Updated Multiviewer with new audio meters. 
• Plus hundreds of additional bug fixes and improvements!

Here are the release notes:

• New & Improved:

• WIRE-17882: Added an option on Wirecast Gear licenses to disable audio capture
from the capture cards.
• WIRE-17852/ WIRE-17835: Added a lock button to link the new width and height
size fields in the Video Properties tab.

Wheel widget.
• WIRE-17674: Add a visual example to the documentation of the Countdown Clock
Display Gear icon menu.
• WIRE-17666: Removed Auto-Canvas option as it was confusing and no longer
serving a useful purpose. New documents will default to 720p. Older documents will be set at their actual canvas size, and you’ll get a warning if your output resolutions don’t match your canvas size.
• WIRE-17628: We updated some code to make our capture card inputs more efficient for Wirecast Gear 300 and 400 series.
• WIRE-17617: Updated the highlight color for Windows buttons to be less obnoxious than the bright green.

audio frames to render for each source. As part of this, we added a new text field to the Advanced section of the Preferences that will let you specify the Global Input Latency Wirecast should use. Lower latency means more possibility of audio blips; longer latency means more delay before video & audio are shown.
• WIRE-17556: We added an option to disconnect all peers when ending a Rendezvous session
• WIRE-17533: Added the ability to set a LinkedIn Live event to "Public" or "Private".

which should result in an improved efficiency and reduced CPU load.
• WIRE-16933: Upgraded our Webstream plugin (libVLC) to version 3.0.8.
• WIRE-16930/ WIRE-16734/ WIRE-6613 /WIRE-14: Introducing Chroma Key v2:
Added new features to our Chroma Key to enable more accurate keying, including
spill suppression, edge coloring, clipping ranges and more.
• WIRE-16929: Introducing Color Key: Added a new Color Key feature which keys
using colors in the RGB space. Useful for images (logos) that have non-black and
non-white backgrounds.
• WIRE-16928: Introducing Luma Key: Added a new Luma Key feature which sets
the image alpha based on the intensity (y) value, ignoring the color (U and V) values. This is useful if you have a logo with a white or black background you wish to remove.

(Stinger) transitions.
• WIRE-14072: We added an improvement so that all sources appear and disappear
from the source list while the Add Source dialog is showing, so you no longer need
to close and reopen the dialog to see updates.

the option for disconnected shots to be replaced with the red question mark, a
transparency, or an image of your choice.

• WIRE-17142: When sending live captions through our WebServices platform, certain platforms are not handling b-frames correctly resulting in garbled captions. To account for that, we added new "Cloud Captioning" encoding presets that turn b-frames off and increase bit rate (to account for inherent quality loss of turning off b-frames).
• WIRE-17278: Now your encoding preset won’t spontaneously change after you create an event.
• WIRE-17133: Add documentation for sources that can be used with ISO Recording.
• WIRE-17126: Selected transition was not used when using Keyboard Shortcuts when AutoLive was enabled.

• WIRE-16825: Fixed a rare hang when exiting to Multiviewer while ingesting a
BlackMagic source.
• WIRE-16820: Added CPU data to the trace log on exit.
• WIRE-16811: Added a manual configuration option for audio sample rate that will
let you pick the value that matches your incoming source. (Note: you can only configure the audio sample rate when automatic format detection is disabled. We do this to prevent people (we won't name names) who don't know what they're doing, to set it to 196kHz - because they may think bigger is better - and then call support or get stuck because they don't understand what's happening. So, yeah. We're restricting this for your own good. When format detection is enabled, we assume the audio is 48 kHz.)
• WIRE-16799: Crash when declining a macOS prompt to install Osaka font.
• WIRE-16779: Fixed a crash that would occur when stopping two live streams to
Twitter/Periscope.
• WIRE-16778: Fixed an issue playing audio from WASAPI devices.
• WIRE-16776: We've taken some extraordinary measures to ensure that web
stream sources stay connected and don't freeze in Wirecast - even if they restart, end, enter an error state or we stop receiving data for any number of reasons. We now try our darnedest to reconnect.
• WIRE-16768: Output Settings UI has some minor alignment issues on macOS.
• WIRE-16763: Fixed a crash that could occur if you had a hotkey with no name,
and you right-clicked a shot.
• WIRE-16762: Fixed an issue that could occur when using a source that produces
JPEG frames, on a computer that is not fast enough to decode them in real-time.
The result was a backlog of frames that would cause the source's video to be delayed and out of sync with any live audio. (This could've also happened when deinterlacing video from a task source (though less likely since deinterlacing is relatively quick).
• WIRE-16760: Wirecast was trying to use deselected/unused output destinations when Live Captions was selected. It won't do that anymore.
• WIRE-16747: Fixed our copyright date in the About window.
• WIRE-16745: Flash is dead. We're not going to warn you that it's not installed
anymore.
• WIRE-16713: Reconfigured NDI Output to avoid "clocking" the output which was
intended to help file-based outputs but effectively slowed down real-time sources,
resulting in for example, dropped frames at 1080p60.
• WIRE-16694: Reconfigured NDI Output, which effectively improved several
issues- one of which was an observed A/V sync issue on NDI Out.
• WIRE-16684: Fixed an issue that cause no video from the Logitech B910 when

Known Issues
• NOTE: As part of the fix for WIRE-17286, on BlackMagic devices, we now identify them via hardware ID instead of enumeration order. The fallout is that if you have a document that once referred to one piece of hardware it may fail to initially reference a different piece of hardware. The workaround is to use the asset manager to replace the references to the new hardware. Once done, that document should save your new sources as expected.
