Link your HyperCaster to your TelVue Connect account to use available SmartCaption automatic closed captioning for HyperCaster Live & Offline captioning. HyperCaster Live captioning requires SmartCaption LIVE channel licenses compatible with AIO, B100-SDI/ANA, and ProVue models, and an Internet connection for your HyperCaster to communicate securely with Connect. SmartCaption’s usage-based pricing saves you considerable money allowing you to designate which Series, Live Sources, and Files are captioned, or limit captioning to unique programming hours. Program-specific Custom Language Models makes it easy to improve caption accuracy for your meetings and programs. Set-and-forget automation rules right in your HyperCaster makes captioning 100% automated. With the addition of the SmartCaption Caption Translation feature, the HyperCaster can translate live captioning to a secondary language for dual language broadcast caption output on CC1/CC3, such as simultaneous English and Spanish. Uploading to Connect from your HyperCaster publishes generated and translated captions for CloudCast streaming, mobile, OTT, and Media Exchange. Contact sales@telvue.com to get setup with SmartCaption and SmartCaption LIVE.
To get started, first link your HyperCaster to your TelVue Connect account by adding a Connect Remote Server with your Connect account credentials. The HyperCaster will recognize if you have SmartCaption captioning and SmartCaption Caption Translation enabled in TelVue Connect, and will present additional automatic captioning features. The HyperCaster will synchronize your default captioning settings from Connect, and you can change the HyperCaster defaults in the Captioning Configuration. For offline file-based captioning, automatically generated captions are stored as WebVTT sidecar files and will display during playback if you enable the Embed Captions? option on a channel for supported models. For live event captioning, additionally enable the SmartCaption LIVE? channel option. Embedded offline and live captioning is output as standard 608/708 captioning on SDI and IP outputs. HyperCaster SmartCaption captioning and translation usage minutes for Live & Offline are registered back to your TelVue Connect account. TelVue Connect can be configured to send email alerts when available captioning minutes or translation characters dips below a configurable threshold.
Offline Captioning
For offline file captioning, you will see a new file action available to Generate Closed Captions. With Caption Translation enabled, you will also see a Translate Closed Captions file action for any content that already has a Primary caption track available to translate.
Selecting the Generate Closed Captions action will present Caption Generation Options initially set to your defaults.
The Caption Generation Options are as follows:
- Source Language: Identify the spoken language in the programming.
- Custom Language Model: Optionally select a custom language model to be used when automatically generating captions. Custom Language Models are created and managed in TelVue Connect, and the HyperCaster automatically syncs the available models.
- Profanity Filter: If selected, filters profanity from all output except for keyword results by replacing inappropriate words with a series of asterisks. Uncheck the box to return results with no censoring.
If the Caption Translation feature is available, additional options for translation will be presented along with Caption Generation.
The Caption Translation Options are as follows:
- Translate Captions: Check the box to translate the generated captions to a second langauge.
- Translate To: Select the language to which to translate.
Click the Caption button to begin automatic captioning. The Task Tab will show a task for the caption generation background job, and any subsequent translate captions background job. When the task(s) are complete, the captions are attached as a sidecar WebVTT file viewable in the show content Captions tab and the content thumbnail will show the CC icon indicating captions are present. Generated captions will be the Primary, and any Translated captions will be the Secondary.
Selecting the Translate Closed Captions action will present Caption Translations Options initially set to your defaults.
Select the language to which to translate and click the Translate button to begin translating the captions. The Task Tab will show a task for the translate captions background job. When the task is complete, the translated captions are attached as a Secondary sidecar WebVTT file viewable in the show content Captions tab.
The show content Captions tab displays the automatically generated sidecar captions. The captions can be viewed or downloaded as WebVTT. Content previews will show the captions if you enable captions in the preview player’s control bar via the CC button. If you trim the content, caption playback will honor the trim points as well to keep everything in sync. With the SmartCaption editor feature enabled in your linked TelVue Connect account, an edit link will also be displayed so you can edit captions directly in the HyperCaster user interface.
For automatic offline captioning of specific programming, organize your programming into Series, enable the Caption? option for the series and select the desired caption and translation settings in the Captioning section including any program-specific Custom Language Models. All Episodes added to the series will be automatically captioned per the settings in the background so captions will display on scheduled playout and replays.
Live Captioning
For automatic live captioning of specific programming, designate specific live series and live sources to be automatically captioned.
For Series, enable the Caption? option for the series and select the desired caption and translation settings in the Captioning section including any program-specific Custom Language Models. All live events for that series will be automatically captioned per the settings on channels with SmartCaption LIVE enabled.
For live sources including Feeds (Live Streams & NDI), Inputs (AIO SDI Inputs), and Switch Inputs, enable the Caption? option in the corresponding source configuration and select the desired caption and translation settings in the Captioning section including any source-specific Custom Language Models. All live events for those sources will be automatically captioned on channels with SmartCaption LIVE enabled. If a live source designated for captioning is used in a series, the series caption settings will override. When captioned live events are both played-out and recorded, the live captioning is saved and automatically associated with the recording for future replays. Live events that are only recorded can be offline captioned after the recording completes, either manually, or automatically as part of a Series configured for captioning.
Dashboard Channel Confidence Monitoring and Previewing will show Primary and any Secondary captions from both uploaded and generated sidecar captions and native 608/708 captions if you enable captions in the player’s control bar via the CC button. You can select which caption track to view by clicking the video player CC icon.
Publishing to Connect & CloudCast
Uploading content to Connect with SmartCaption automatically generated captions will upload the Primary and any Secondary caption files along with the video. The caption file(s) will be attached to the Connect media record and are available in Connect for all supported workflows including CloudCast Streaming, Mobile & OTT, multi-language Caption Translation, as well as embedding Primary captions as 608/708 during cloud transcoding for Broadcast & Media Exchange.
