What it carries

Two to five scenes cut one after another under one title, each a small format of its own: a text, a number, a change, bars or a list. 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: a kicker, the title, the scenes in order, the source and the look.
`clipData.kicker`	text		up to 20 characters	Kicker: A word above the title, such as CLOSING BELL or MONTHLY REPORT.
`clipData.title`	text	yes	up to 80 characters	Title: What the scenes add up to, on screen over all of them.
`clipData.scenes`	list	yes	at least 2, up to 5	Scenes: Shown one after another in this order, each a small format of its own. Each scene reads the fields its kind needs and ignores the rest. Two to five; each adds about four and a half seconds, and a scene with more to say is given longer.
`clipData.scenes[]`	group			Scene
`clipData.scenes[].kind`	enum	yes	`text`, `number`, `change`, `bars`, `list`	Kind: Text: the text, set line by line. Number: the value, counting up. Change: from and value with their labels, an arrow drawing from one to the other. Bars: items with values, growing one after another. List: items, arriving one by one.
`clipData.scenes[].title`	text	yes	up to 50 characters	Scene title: What the scene shows, at its top.
`clipData.scenes[].text`	text		up to 140 characters	Text: The words of a text scene, or a line of context under any other kind.
`clipData.scenes[].value`	number		4 decimals	Value: The figure of a number scene, or where a change ended. Shown exactly as sent.
`clipData.scenes[].from`	number		4 decimals	From: Where a change started. Without it a change counts up like a number.
`clipData.scenes[].fromLabel`	text		up to 20 characters	From label: Over the starting figure, such as Last year.
`clipData.scenes[].toLabel`	text		up to 20 characters	To label: Over the end figure, such as This year.
`clipData.scenes[].prefix`	text		up to 3 characters	Prefix: Written before the figures, such as a currency sign.
`clipData.scenes[].unit`	text		up to 12 characters	Unit: Written after the figures: a percent sign, kg, hours. On bars it is written once, over the values.
`clipData.scenes[].items`	list		up to 6	Items: The bars of a bars scene, in the order they are shown, or the points of a list scene.
`clipData.scenes[].items[]`	group			Item
`clipData.scenes[].items[].label`	text	yes	up to 36 characters	Label
`clipData.scenes[].items[].value`	number		4 decimals	Value: A bar's value, which sets its length. Not drawn in a list.
`clipData.source`	text		up to 70 characters	Source: Where the content comes from, shown small at the foot. Drawn exactly as written: write its label too, such as Source: at the start, as the template adds no word of its own.
`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 five 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.
`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.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.

Ask Reelwire for the whole JSON Schema, the document this feed is checked against, without signing in:

curl "https://app.reelwire.io/v1/formats/feed/fd_8f2f421691e1"

Which template draws a feed is Reelwire's decision and can change, so a producer asks by the feed, as above, rather than by its template.
