Telestream®, a leading provider of digital media tools and workflow solutions, today announced version 10 of Wirecast, Telestream’s award-winning live streaming and production software for Mac and Windows. The new version adds support for restreaming and live captioning workflows with the introduction of Wirecast Live Captions and Wirecast Restream, two new web services hosted on Telestream Cloud.

Stop using closed captions and SDH: Deselect the “Prefer closed captions and SDH” checkbox. Create a style: Click the Add button, enter a name for. Turn on closed captions and subtitles.

There are two ways to open QuickTime closed captions: as embedded captions that stream at the top or bottom of the screen or using an iPad as an extension of your Mac desktop using Sidecar. This displays the captions on a second screen. There are times where captions, or texts, are added in a film by the production team. They usually use a Film Editing Software for it and this is where integrated closed captions come from. However, there are films that do not have captions. To rescue the day, we have captions to fix that for us. But captions aren’t magically summoned. These services include live captions, subtitles, and transcription functionality available across Office 365 products like Microsoft Teams, PowerPoint, Stream, and others. Teams can detect what's said in a meeting or group call and present real-time captions.

With the release of these new web services for Wirecast customers, Telestream aims to solve two of the most common issues facing live streamers today: the creation of captions for live events and the need for efficient multi-platform distribution, even when upload bandwidth is limited. Wirecast Live Captions is the perfect tool for improving accessibility to live streams for deaf and hard of hearing viewers, and provides affordable, CEA-608 formatted, RTMP-embedded closed captioning to Wirecast streams.

Live Captions uses advanced machine learning-based speech-to-text engines to listen and transcribe the audio from your streams in real-time. Once the speech is transcribed, Telestream’s award-winning captioning technology embeds that text in correctly formatted, compliant CEA-608 closed captions within the RTMP stream, and then distributes it to any destination – all completely within the cloud. This allows any stream generated in Wirecast 10 or later to contain discreet, closed captioning which can be displayed from any closed-captioning compatible web-player.

“Compliant, formatted and embedded 608 live captioning has traditionally been out of reach or too expensive for most live productions and streamers,” said Tom Prehn, Product Manager, Telestream. “This level of quality at an affordable price point is an industry first.”

Although machine-generated, the Wirecast Live Captions service is capable of a high degree of accuracy. When working with clear and intelligible source material, Live Captions is over 90% accurate. Wirecast’s Live Captions service is currently available for 5 languages, including: English (US), English (UK), French, Portuguese (Brazilian), and Spanish.

The other web service, Wirecast Restream, allows users to simulcast their streams to multiple destinations and platforms without sacrificing quality, bandwidth or computing resources. A single upload stream can be “restreamed” to multiple online platform destination platforms using the established architecture of Telestream’s cloud-based media processing ecosystem. Previously, streaming to multiple destination platforms required a powerful workstation to handle multiple simultaneous encode requirements for each destination. A significant network upload connection would also have been necessary to propagate each custom stream to its destination.

“The Restream service allows users to stream to multiple destinations without affecting their bandwidth or processing resources – or even their Wirecast workflows,” said Scott Murray, VP Product Management at Telestream. “With Wirecast 10, it’s now possible to use a much lighter weight computer such as a laptop and a standard internet connection to accomplish a larger multi-platform streamed event.”

Along with the compute and bandwidth advantages it offers, Wirecast Restream is convenient and simple to implement. It allows users to restream to multiple destinations by using a simple check box menu. When users add an output destination in Wirecast, they can decide if they want Restream to deliver the feed for them. Wirecast automatically propagates the correct login credentials and RTMP publishing points to Restream, without the user needing to leave the Wirecast interface.

“We intentionally designed Wirecast 10 so users don’t have to change their workflow to harness these services,” said Prehn. “Users simply sign up for a Telestream Cloud account, add their intended destinations in Wirecast, as they always have, and check the “Enable Restream & Captions” check box for that destination. That’s it.”

Supported Bit Versions
32-bit, 64-bit
Source Code URL
https://github.com/ratwithacompiler/OBS-captions-plugin
Minimum OBS Studio Version
23.0.0
Supported Platforms
Windows, Mac OS X
Provides closed captioning via Google Cloud Speech Recognition API as a standalone OBS plugin. It's fully optional to viewers and uses Twitch's built in caption support which works on livestreams and in VODs on PC, Android and iOS, no Twitch extension required.
Features:
  • Captions only when the microphone source is unmuted and active to ensure safety
  • Works live and in VODs, no Twitch extension required
  • Completely optional for viewers
  • Supports OBS delay
  • Requires no extra tools or website open
  • Supports many common languages with western character sets
Notes:
  • The caption delay is usually less than half a second and should not be noticeable to viewers.
  • The plugin only captions the selected audio source when it's not muted and when it's used on the current active scene to ensure safety and avoid any captioning when the mic is muted for the stream.
  • Video players with caption support like VLC can also show captions on downloaded VODs if enabled.
  • Only tested on Twitch.tv, other streaming services with native caption support might work but not very likely.
  • You can enable and disable the caption preview dock in OBS under View -> Docks -> Captions
  • The quality of Google's Speech Recognition heavily depends on the speaker and what is being said. The results are usually be pretty good in normal conversational settings like talking to chat but the recognition quality can go down noticeably when using ingame terms or other specialized vocabulary or during hectic speaking.
Captions should be off by default for most viewers but Twitch does sometimes have them enabled for some viewers for unknown reasons so occasionally some will be confused on how to turn them off and might need it explained.

Closed Captions Download


  • On PC viewers can turn captions on and off using the CC button on the bottom right of the player.
  • On iOS it's a system wide setting: Settings -> General -> Accessibility -> Subtitles & Captioning -> Closed Captions + SHD
    • If it's already off but viewers still see captions they have to turn it on and off again (appears to be a bug on some iOS versions)
  • On Android it's Closed Captions under the player settings options right beneath the quality selection. The option will only show up once the streamer has talked.
Requires OBS 23.2.1 (released June 15th 2019) or newer!
