Waterfall

How a starting value becomes an end value: the start bar first, then two to ten steps each floating up in the brand's rise colour or down in its fall colour from where the one before ended, its signed figure counting to exactly its value, and the total closing it: 10 to 18 seconds. In eleven styles, each wearing your brand's colours, fonts, logo, presenter and background.

Use cases

How last year became this year: every rise and every fall that made the difference.
An opening balance to a closing one, a budget to what was spent.
Rises in your rise colour, falls in your fall colour, the total worked out from the steps.

Variants

A variant is this template drawn another way, and it comes in versions: immutable builds, the newest first. A channel follows the newest version of its variant, unless it is pinned to one.

What it accepts

Every variant takes the same content, so one document draws in any of them.

Waterfall: how a starting value becomes an end value, the start bar first, then two to ten steps each floating up in the brand's rise colour or down in its fall colour from where the one before ended while its signed figure counts, and the total closing it. metaData is the post's title, descriptions and hashtags and is never drawn.

Field	Type	Required	Limit	What it is
`clipData`	group	yes		Clip data: Everything drawn: the title, the start, the steps, the end's name, the note, the source and the look. The end is the start with every step added.
`clipData.kicker`	text		up to 20 characters	Kicker: A word or two above the title, such as THE YEAR.
`clipData.title`	text	yes	up to 80 characters	Title: What the steps explain. Shown from the first frame.
`clipData.startLabel`	text	yes	up to 24 characters	Start's name: What the first bar is, such as Last year or Opening balance.
`clipData.start`	number	yes	2 decimals	Start: The value the steps start from.
`clipData.steps`	list	yes	at least 2, up to 10	Steps: Two to ten, in the order meant, each a rise (a positive value) or a fall (a negative one) in the same unit as the start. Each adds a second.
`clipData.steps[]`	group			Step
`clipData.steps[].label`	text	yes	up to 28 characters	Name
`clipData.steps[].value`	number	yes	2 decimals	Change: Positive for a rise, negative for a fall.
`clipData.endLabel`	text	yes	up to 24 characters	End's name: What the last bar is, such as This year or Closing balance. Its value is the start with every step added.
`clipData.prefix`	text		up to 6 characters	Prefix: Before every figure, such as a currency sign.
`clipData.unit`	text		up to 10 characters	Unit: After every figure, such as m or %.
`clipData.note`	text		up to 100 characters	Note: One line under the steps.
`clipData.source`	text		up to 70 characters	Source: Where the figures come from, at the foot. Drawn exactly as written.
`clipData.styleWords`	group			Style words: The few words some styles write into their own frame, each drawn exactly as written, in the language you write it in. A word left out is not drawn: no template adds a word of its own. The same keys in every format of the collections; each style draws only its own.
`clipData.styleWords.live`	text		up to 16 characters	Live marker (Broadcast news): Written beside the light in Broadcast news' channel bug, such as LIVE. Left out, the light stands alone.
`clipData.styleWords.byline`	text		up to 12 characters	Byline (Editorial): Written before the presenter's name in Editorial, such as By. Left out, the name stands alone.
`clipData.styleWords.functionKeys`	list		up to 4	Function keys (Data terminal): Data terminal's row of keys F1 to F4, one word each, in order, such as HELP, DATA, CHART and NEWS; the second is drawn held down, and a key that does not fit the row is left out. Left out, no keys are drawn.
`clipData.styleWords.functionKeys[]`	text		up to 12 characters	Key
`clipData.styleWords.commandKey`	text		up to 10 characters	Command key (Data terminal): The key at the end of Data terminal's row, in the rise colour, such as GO. Left out, none is drawn.
`clipData.styleWords.realTime`	text		up to 12 characters	Real-time light (Data terminal): Written beside the blinking light in Data terminal's status bar, such as RT. Left out, the light stands alone.
`clipData.styleWords.messageLabel`	text		up to 12 characters	Message window label (Data terminal): The tab on Data terminal's message window round the presenter, such as MSG. Left out, the window has no tab.
`clipData.styleWords.pictureLabel`	text		up to 12 characters	Picture panel label (Data terminal): Written in the strip along the top of Data terminal's picture panels, such as IMG. Left out, the strip stays empty.
`clipData.look`	group			Look: How the clip looks and moves within its style. The same switches in every format of the collections. Leave a switch out, or set it to the style's own, and the style decides.
`clipData.look.theme`	enum		`auto`, `brand`, `light`, `dark`, `bold`	Theme: The style's own choice; your brand's own colours and background; a light or dark page tinted with your brand colour; or your brand colour as the page.
`clipData.look.pace`	enum		`auto`, `calm`, `standard`, `punchy`	Pace: How things arrive: the style's own rhythm, calm fades, a standard rhythm, or punchy slams and cuts.
`clipData.look.corners`	enum		`auto`, `square`, `soft`, `round`	Corners: The shape of cards, panels and marks.
`clipData.look.align`	enum		`auto`, `start`, `centre`	Text alignment: Where the text lines up.
`clipData.look.logo`	enum		`auto`, `free`	Logo: The style's own: the logo on the style's plate (a card, a disc, a badge) so it reads on any page. As it is: the logo whole, with no plate, frame or crop, for a logo made to stand on the page, such as one with a transparent background. As it is, make sure your logo reads on the page of the theme you choose.
`clipData.look.logoSize`	enum		`auto`, `small`, `large`	Logo size: Standard is the style's own size. Small draws the logo a fifth smaller, with its plate. Large draws it a quarter larger wherever the style has room for it, and at the standard size where it has none.
`clipData.look.hideHeader`	boolean			Hide logo and title: Leaves out the line at the top of the clip: your logo, the title line and the style's decoration around them, so the content starts at the top. To leave it out of every clip, switch Logo and title line off in your brand's settings.
`clipData.look.hideFooter`	boolean			Hide footer line: Leaves out your footer line at the foot of the clip, with whatever the style draws only to carry it, so the content reaches further down. Your presenter and the source line stay. To leave it out of every clip, switch Footer line off in your brand's settings.
`clipData.look.pattern`	enum		`auto`, `none`, `dots`, `grid`, `lines`	Background pattern: The fine texture behind the content. The style's own keeps what the style draws there, and some styles draw none. None leaves the background plain. Dots, Grid and Diagonal lines draw that pattern faintly instead, the same in every style, in the colour of your page.
`metaData`	group			Meta data: Everything about the post that is never drawn in the clip: its title, its description in four lengths, one per kind of platform, and its hashtags. Reelwire adds the brand's description, link and hashtags after it. Left out, the post text is generated from the clip data.
`metaData.title`	text		up to 100 characters	Title: Used where the platform has a title of its own: Facebook Feed, LinkedIn, Pinterest and YouTube. Up to 100 characters, which every one of them takes.
`metaData.captionTiny`	text		up to 200 characters	Tiny description (Pinterest, Threads, X): Up to 200 characters. The brand's description, link and hashtags follow it within the platform's limit.
`metaData.captionShort`	text		up to 500 characters	Short description (Telegram, Threema, WeChat, WhatsApp): Up to 500 characters. The brand's description, link and hashtags follow it within the platform's limit.
`metaData.captionMedium`	text		up to 1500 characters	Medium description (Discord, Facebook Reels, Instagram, LinkedIn, Signal, Slack, TikTok): Up to 1500 characters. The brand's description, link and hashtags follow it within the platform's limit.
`metaData.captionLong`	text		up to 4000 characters	Long description (Facebook Feed, YouTube): Up to 4000 characters. The brand's description, link and hashtags follow it within the platform's limit.
`metaData.hashtags`	list		up to 15	Hashtags: Written without the #. Up to 15, which every platform takes.
`metaData.hashtags[]`	text		up to 60 characters	Hashtag

locales carries other languages: under each language code, the parts of clipData and metaData that differ, laid over the default, so a language with no copy still renders.

A picture is always a file from your media library: media:// followed by its id or its name. Anything the table does not list is refused, and so is anything over its limit, with a 400 schema_validation error that names the field.

Delivery JSON

Your own system sends this to one of your streams, POST /v1/stream, and every channel listening to that stream draws it with its template. data is the document described above; a stream with an empty field map passes it to the template unchanged. Try it first on POST /v1/stream/validate, which answers the same without publishing anything. Streams and feeds explains the rest, including how to map a document of your own shape instead.

The delivery names no version: which build draws it is the channel's choice, the newest of its variant or the one it is pinned to. eventId is a ULID you make once per event: sending the same one again changes nothing. occurredAt is when the thing happened, not when you sent it. locale is the language of the text in data, and data.locales carries other languages beside it.
