Webvtt sample file download

You can use WebVTT cue components to add more information to the cue text. These cue components are similar to HTML elements, and can be used to add semantics and styling to the actual text strings. Some available options are i for italics, b for bold, u for underlined text, and so on. The following is an example WebVTT file with cue settings align and cue components bold.

Provide the subscribers with the URL for the m3u8 file. For example, to access the VoD content named sample. Use f4mconfigurator tool to generate a set-level or a variant playlist with both the m3u8 files in the required format. Each URL is named to indicate the start time of the contained caption text. The duration T is configured in httpd. The URLs can be absolute or relative.

The following diagram illustrates how the width , lines , regionanchor , and viewportanchor attributes relate to the desired positions and geometry. The scroll setting defines how subtitle text is rendered within the region.

See Rendering Style below for more details. With pop-on captions, the entire cue appears all at once at the specified start time and disappears all at once at the specified end time. This is the default mode for rendering captions and is the most common rendering mode for web videos.

In WebVTT, pop-on captions are the default rendering style. Roll-up captions are rendered one line at a time at the bottom of the caption box. Each new line pushes up the existing lines until they scroll off of the top of the box. This rendering style is typically used in live television broadcasts, which is where the term closed captioning originated. With live captioning, the bottom line is often progressively rendered, one word at a time.

In WebVTT, roll-up captions are rendered one entire line at a time. To use roll-up captions, a region must be defined and include the scroll:up setting. Then, each cue should reference that region, and the cues should have overlapping times with durations long enough to keep the cue visible until it scrolls out of the box.

The following example shows roll-up captions:. Paint-on captions appear one word or phrase at a time. They are also called karaoke-style captions, since that is a common use for them.

WebVTT supports paint-on captions through use of timestamp tags that are embedded in the cue payload text. If a cue contains multiple timestamp tags, they must appear chronologically. That is, each timestamp tag must be greater that the previous one. At the time indicated by the first timestamp tag, the second segment of text up to the next timestamp is displayed, and so on until there are no more timestamps.

In the above example, each word or phrase is rendered as it is sung. To provide a better readability while still preserving the paint-on nature of the captions, we can show the entire caption, but just paint portions of the text different colors to indicate the word or phrase currently being spoken or sung.

For example, when the cue payload text is first shown on the screen, it would be colored grey to indicate that it is future text. When the first timer fires, the corresponding text becomes active and is changed to blue. When the subsequent timer fires, a new segment becomes active. The old active segment becomes past text, and is changed to black. In order to accomplish this, WebVTT defines two pseudo-classes: :past and :future.

For the example at hand, the two classes would be defined in the CSS as follows:. This rendering style would be particularly useful for karaoke. Beyond karaoke, paint-on captions in general are helpful for conveying the cadence of music or speech to the hearing-impaired.

The text box below the video shows you the WebVTT file for those same captions. WebVTT is just one of many formats you can download once the captions have been created. You could then use the WebVTT file to allow various players and video hosting services to present captions with your video see compatibility list below. The WebVTT file format is supported by most video players, streaming platforms, authoring tools, editing software, including:. The reason is that they wanted to support the following advanced features: Basic inline text formatting —Basic HTML tags can be inserted to format either an entire caption aka cue or just portions of it.

Voice Tags —Tags can be used in cues to indicate who is speaking. Ruby characters —Ruby characters are small textual annotations i. Chinese script or Japanese Kanji to show the pronunciation of characters that are likely to be unfamiliar to the reader. Regions —Areas of the screen regions can be defined, and each cue can be directed to any defined region.

Positioning —The location on the screen may be specified on a cue-by-cue basis or via defined regions that are referenced by captions. Alignment and Direction —Text can be left, right, or center-aligned within the caption box, and the horizontal left-right and vertical up-down text direction can be specified as well. Rendering Style —Pop-on, Paint-on, and Roll-up captions are supported. That file you can edit and reuse. There are lots of formats that used in video files.

Comments are an optional component that can be used to add information to a WebVTT file. Comments are intended for those reading the file and are not seen by users. Comments may contain newlines but cannot contain a blank line, which is equivalent to two consecutive newlines. A blank line signifies the end of a comment. You can style WebVTT cues by looking for elements which match the ::cue pseudo-element. Here, all video elements are styled to use a gray linear gradient as their backgrounds, with a foreground color of "papayawhip".

You can also define the style directly in the WebVTT file. We can also use identifiers inside WebVTT file, which can be used for defining a new style for some particular cues in the file. The example where we wanted the transcription text to be red highlighted and the other part to remain normal, we can define it as follows using CSS.

Positioning of text tracks is also supported, by including positioning information after the timings in a cue, as seen below see Cue settings for more information :. A cue is a single subtitle block that has a single start time, end time, and textual payload. Example 6 consists of the header, a blank line, and then five cues separated by blank lines. A cue consists of five components:. The identifier is a name that identifies the cue.

It can be used to reference the cue from a script. It must end with a single newline. They do not have to be unique, although it is common to number them e. A cue timing indicates when the cue is shown. It has a start and end time which are represented by timestamps.

The end time must be greater than the start time, and the start time must be greater than or equal to all previous start times. Cues may have overlapping timings. Cue settings are optional components used to position where the cue payload text will be displayed over the video. This includes whether the text is displayed horizontally or vertically.

There can be zero or more of them, and they can be used in any order so long as each setting is used no more than once. The cue settings are added to the right of the cue timings. There must be one or more spaces between the cue timing and the first setting and between each setting. A setting's name and value are separated by a colon.

The settings are case sensitive so use lower case as shown. There are five cue settings:.
