Automation: Rules that let CaptionHub create and process projects without manual steps. When new media arrives from a connected platform, for example, automation can create the project, apply settings such as languages, termbases, and workflow, and start transcription or translation. Automation needs to be set up before it runs through an automation template.
Burnt-in subtitles: Subtitles that are permanently embedded in the video itself and can't be separated from it. Also known as hardcoded subtitles or open captions. Burnt-in subtitles can be downloaded from CaptionHub on most plans.
Caption: A single subtitle shown on screen, usually one or two sentences.
Caption set: A complete set of captions for a video in one language. One caption set subtitles the whole video.
CaptionHub Connect: A way to work with external vendors, such as language service providers, directly in CaptionHub. With CaptionHub Connect, you can send caption sets to a vendor for translation or review and receive the finished work back in the same project, without exchanging files by email.
Connector: An integration between CaptionHub and a third-party platform, such as an online video platform (OVP), translation management system (TMS), or voiceover tool. Depending on the platform, a connector can bring media or content into CaptionHub, send finished captions or translations back, or pass work to another service.
Folder: A way to group related projects, such as by client, campaign, or show. Each project sits in one folder, so use folders for the main way you organise your work.
Language: Any language a caption set can be in, whether it's an original caption set or a translation.
Language version: The subtitles or captions for a single language within a project. A project has one source language version (usually a transcription of the original audio) and can have any number of translated language versions. You may also see these referred to as caption sets or translations.
Project: A set of caption sets for a single video. Each project has exactly one video.
Snapshot: A record of all the changes a user made to a caption set before handing it over.
Tag: A label you add to projects to mark something about them, such as priority, status, or content type. A project can have several tags, so use tags for anything that cuts across folders.
Team: A group of users and projects, typically a single organisation or department. Each project belongs to one team, and everyone working on it must be part of that team. Projects can't be seen by users outside the team, other than admins.
Timed text: A file containing subtitle text and its timings, which you can download from CaptionHub as a final deliverable. Timed text files are separate from the video, so you'll need a player that supports them to display subtitles. Common web formats are SRT and VTT; broadcast formats vary more widely.
User: Anyone who uses CaptionHub. There are several user roles:
- Language supervisors manage work for one or more assigned languages. They can review, edit, and approve language versions in their languages, but can't access account settings or other languages.
- Linguists are translation users with proficiency in specific languages. They can only work on caption sets they have permission for. To be assigned to a caption set, a linguist must be proficient in its language and belong to the project's team.
- Producers are managerial users. They can assign linguists, hand over projects to other linguists, and see all activity on a project, but can't translate captions.
- Reviewers are linguists who carry out the final review of a language version. They add an extra layer of quality control when more than one linguist is involved, checking subtitles after translation and giving final approval. Reviewers are only used when the Direct assignment with review or Self serve with review workflow is enabled.
- Superusers are in charge of a team. They can create users and projects within their team, but can't see outside it.
View: A saved set of filters that shows a specific list of projects; use them to find work quickly without reorganising it.
Workflow: The process that decides how caption sets are assigned to linguists and move through translation and review. CaptionHub offers several workflows, such as direct assignment and self serve, each with an optional review step.
