Configuring StreamUP BBCode

by StreamUP

Version: 0.1.0

A text source for OBS that actually lets you style things. Bold, colours, gradients, animations, live countdowns, Google Fonts. All rendered natively inside OBS. No browser sources. No external services. Just type tags, get styled text.

If you've ever tried to make good-looking text overlays in OBS, you know the pain. This fixes that.

Requires OBS 31.0 or newer


What is BBCode?

BBCode is a simple way to format text using tags in square brackets. If you've ever used a forum, you've probably seen it before.

[b]this is bold[/b]

Opening tag, your text, closing tag. That's it.

You can nest them too. Want bold red text? Just wrap one inside the other.

[b][color=#ff4444]Bold and red[/color][/b]

Add an animation and it comes to life.

[rainbow speed=2]Colourful streaming text[/rainbow]

Adding the Source

  1. In your scene, click + under Sources
  2. Select StreamUP BBCode from the list
  3. Type your text with tags in the Text field
  4. Hit Open Editor for a proper editing experience, or Tag Reference if you forget a tag

BBCode Editor

Click Open Editor in the source properties. This opens a standalone editor that's a lot easier to work with than the small text box in properties.

What you get:

  • Syntax highlighting that colour-codes your tags, variables, and presets
  • Live preview that updates as you type, using the same rendering as OBS
  • Toolbar with buttons for bold, italic, underline, font, colour, outline, shadow, glow, alignment, wave, rainbow, typewriter, and more
  • Tag sidebar with all tags sorted by category. Search by name or description. Double-click any tag to insert it.
  • Variables tab to view, add, edit, and delete your global variables without leaving the editor
  • Presets tab to manage your style presets
  • Find with Ctrl+F to search your text
  • Colour picker built into the colour button

The preview at the bottom shows exactly what your text will look like in OBS. If a tag has animation, the preview animates it too.

The editor closes automatically when you close the source properties window.


Quick Example

Hello [b]World[/b]!
[color=#ff0000]Red[/color] [i]italic[/i]
[wave amp=30 freq=4]Wavy[/wave]
[rainbow speed=2]Rainbow[/rainbow]

Bold, colour, a wave animation, and rainbow cycling. All in one source.


Tags

81 tags across 8 categories. Here's all of them.

TIP

The previews below use the exact same animation maths as the plugin. What you see here is what you get in OBS.

Formatting

Bold, Italic, Underline, Strikethrough

The basics. Wrap your text and it does what you'd expect.

[b]Bold text[/b]
[i]Italic text[/i]
[u]Underlined[/u]
[s]Struck through[/s]

Font Family

Change the font for a section of text. Uses any font installed on your system.

[font=Georgia]Georgia font[/font]
[font=Impact]Impact font[/font]
Georgia   Impact   Courier New   Comic Sans

Font Size

Set the size in pixels. Range is 1 to 500. There are also [big] and [small] shortcuts.

[size=72]Big text[/size]
[size=12]Small text[/size]
[big]1.5x bigger[/big]
[small]0.67x smaller[/small]

Subscript and Superscript

H[sub]2[/sub]O
E=mc[sup]2[/sup]
H2O    E=mc2    Xn+1

Monospace

[code]fixed-width text[/code]
[tt]same thing[/tt]
Normal text vs fixed-width code

Drop Cap

Makes the first character large, spanning multiple lines. Good for story intros or title cards.

[dropcap]Once upon a time...[/dropcap]
[dropcap lines=4]Text[/dropcap]
Once upon a time in a land far, far away there lived a streamer who wanted their text overlays to look good...

Google Fonts

Use any of 500+ Google Fonts. The plugin downloads and caches them automatically the first time.

[gfont=Lobster]Fancy text[/gfont]
[gfont=Permanent Marker]Marker text[/gfont]

No setup needed. Just type the font name. There's also a dropdown in the properties panel with a Copy Tag button that puts [gfont=Name] on your clipboard.

Script Font   Consolas   Georgia

INFO

500+ Google Fonts are available. The plugin downloads and caches them automatically on first use.


Colours

Named Colours

Over 140 colour names are supported. Case doesn't matter, underscores and hyphens are optional.

[color=red]Red text[/color]
[color=dodgerblue]Blue text[/color]
[color=coral]Coral text[/color]

[colour] works too. Proper spelling.

[texture image=wood.jpg]Textured[/texture]

Mask

Clips text to a mask image. White areas are visible, black areas are hidden.

[mask image=shape.png]Masked text[/mask]

Word Wrap

Forces a specific wrap mode. You rarely need this. With Custom Size turned on, the plugin auto-wraps text and emotes at the source boundary, preferring word boundaries and falling back to character breaks. Only reach for [wrap] if you want to override the default word-first behaviour with char mode.

[wrap=word]Long text that wraps at word boundaries[/wrap]
[wrap=char]Wraps mid-character if needed[/wrap]
This is a long sentence that wraps at word boundaries within the source width

Animations

All animations run per-character with a staggered offset, so they ripple across the text naturally.

[hacker speed=4 loop=2]Decoding text[/hacker]
ParameterDefaultWhat It Does
speed4Characters revealed per second
loop2Seconds to wait before restarting (0 = no loop)

Glitch

Random characters get temporarily replaced with junk. Looks like corrupted data.

[glitch rate=5 intensity=1]Glitchy text[/glitch]
ParameterDefaultWhat It Does

Credits

Scrolls all content upward like movie end credits. Set your source to Custom Size in the Layout settings to define the visible window, and the text scrolls up through it.

[credits speed=50]
[center][size=48][b]THE END[/b][/size][/n]
[/n]
Producer[/n]
[color=gold]StreamUP[/color][/n]
[/n]
Special Thanks[/n]
[color=gold]Everyone watching[/color][/center]
[/credits]
ParameterDefaultWhat It Does
speed50Scroll speed in pixels per second
looptrueLoop back to the start when done (true or false)

Content starts below the viewport and scrolls up through it. Works with any tags inside. Colours, alignment, animations, all of it.

Set loop=false if you want it to stop at the end instead of looping back.

TIP

For a classic credits look, use [center] to centre-align everything and add [/n] newlines between sections.

Curve

Places text along a curved arc. Good for logos or decorative headers.

[curve radius=200 angle=180]Curved text[/curve]
ParameterDefaultWhat It Does

Dynamic Content

These tags update in real time. Countdowns count, clocks tick, variables change when you tell them to.

Countdown

Live countdown timer from a number of seconds. Displays as MM:SS.

[countdown=120]

Counts down from 300 seconds (5 minutes) in real time.

Counter

Animated number that counts from one value to another over a set duration.

[counter from=0 to=99.9 duration=3 decimals=1]
ParameterDefaultWhat It Does
from0Starting number
to100Ending number
duration5How many seconds to count over
decimals0Decimal places to show

Clock

Live system clock. Uses Qt time format strings. Supports timezones via the tz parameter using IANA timezone names.

[clock format="HH:mm:ss"]
[clock format="hh:mm AP"]
[clock format="HH:mm" tz="America/New_York"]
[clock format="HH:mm:ss" tz="Europe/London"]
[clock format="HH:mm" tz="Asia/Tokyo"]
[clock=HH:mm:ss tz=UTC]
ParameterDefaultDescription
formatHH:mm:ssTime format string
tz(system)IANA timezone name (e.g. America/New_York, Europe/London, UTC)

Common formats: HH = 24h hours, hh = 12h hours, mm = minutes, ss = seconds, AP = AM/PM.

When tz is omitted, the clock uses your system's local timezone. Use any standard IANA timezone identifier -- you can find the full list at Wikipedia: List of tz database time zones.

Date

Live date display with named presets so you don't have to remember format strings. Uses the same rendering as [clock] under the hood.

[date]
[date=long]
[date=us]
[date=full tz=America/New_York]
PresetFormatExample
(default)yyyy-MM-dd2026-03-30
shortM/d/yy3/30/26
longMMMM d, yyyyMarch 30, 2026
isoyyyy-MM-dd2026-03-30
usMM/dd/yyyy03/30/2026
eu / ukdd/MM/yyyy30/03/2026
writtenddd, MMM d yyyyMon, Mar 30 2026
fulldddd, MMMM d, yyyyMonday, March 30, 2026
dayddddMonday
monthMMMM yyyyMarch 2026
yearyyyy2026

You can also pass a custom Qt date format string instead of a preset name. The tz parameter works here too, same as [clock].

Time

Live time display with named presets for 12-hour, 24-hour, and other common formats.

[time]
[time=12h]
[time=hours]
[time=military]
[time=12h tz=Europe/London]
PresetFormatExample
(default)HH:mm:ss14:30:45
12h / 12h:mm AP2:30 PM
24h / 24HH:mm:ss14:30:45
shorth:mm AP2:30 PM
longh:mm:ss AP2:30:45 PM
hoursHH:mm14:30
militaryHHmm1430
minimalh:mm2:30
secondsHH:mm:ss14:30:45

Same deal as [date]. Named presets or custom format strings, with optional tz for timezone.

Time Since

Shows how long it's been since a given date or timestamp. Updates live every second. Good for stream uptime, event timers, "account age" displays, that sort of thing.

[timesince=2024-01-15 format=hms]
[timesince=January 15, 2024 format=clock]
[timesince date=1/15/2024 format=short]
[timesince epoch=1705320000 format=long]

You can use pretty much any date format you want. ISO dates, written dates, US slash format, European dot format, whatever feels natural. A raw Unix epoch still works too if that's your thing. The format parameter controls how the elapsed time looks.

Accepted date formats:

  • 2024-01-15 or 2024-01-15 12:00:00 (ISO)
  • January 15, 2024 or Jan 15, 2024 (written)
  • 15 January 2024 or 15 Jan 2024
  • 1/15/2024 or 01/15/2024 (US slash)
  • 2024/01/15 (year-first slash)
  • 15.01.2024 (European dot)
  • 15-01-2024 (European dash)
  • 1705320000 (Unix epoch)

All of these work with or without a time component (e.g. Jan 15, 2024 2:30 PM).

PresetExample OutputWhat It Shows
hms (default)2h 15m 30sHours, minutes, seconds. Auto-hides zero days/hours
hm2h 15mSame but no seconds
clock02:15:30Digital clock style with zero-padding
short2 hours agoBiggest unit only, casual
long2 hours, 15 minutes, 30 secondsFull breakdown
compact2:15:30Minimal, no labels
days45d 2h 15mAlways shows days

If the timestamp is far enough back, days are included automatically. The output scales to whatever makes sense for the duration.

Combine it with styling like anything else:

Stream uptime: [color=lime][timesince=2026-04-01T12:00:00 format=clock][/color]

Random Words

Cycles through a list of words at a set speed.

[random words="Hello,Hi,Hey,Yo" speed=2]
ParameterWhat It Does
wordsComma-separated list of words to cycle through
speedHow many words per second (default 2)

Variables

Placeholder that gets replaced when you set a value via WebSocket or the Variable Viewer. Useful for alerts, notifications, scoreboards, anything triggered by stream events.

Welcome [var=username] to the stream!

Shows as {username} until a value is set. Variables are global, so setting one updates it across all BBCode sources. They persist across OBS restarts.

Variable values support BBCode. Set a variable to [b][color=red]Andi[/color][/b] and it renders as bold red text, not literal tags.

See the Variable Viewer section for managing variables in the UI, or the WebSocket section for setting them programmatically.

Inline Image

Display an image inline with your text.

[img src=C:/images/logo.png width=32 height=32]

Emote Tags

Four provider tags pull emotes straight into your text by name. Twitch, 7TV, BetterTTV, and FrankerFaceZ all supported.

Twitch Emotes

[twitchemote=Kappa]
[twitchemote name=fallen643Bonk]
[twitchemote name=argickJam channel=argick]

Works with global emotes, sub emotes, bit emotes, and channel emotes. If you know which channel owns the emote, pass channel= for a faster lookup. If you don't, the plugin figures it out on its own.

7TV

[7tv=PagMan]
[7tv name=peepoSit channel=forsen]

BetterTTV

[bttv=KEKW]
[bttv name=monkaHmm channel=sodapoppin]

FrankerFaceZ

[ffz=monkaS]
[ffz name=ZULUL channel=xqc]

Sizing

Emotes render inline at text height by default. Override with size, width, or height if you want them bigger.

[twitchemote=Kappa size=64]
[7tv name=PagMan width=96 height=96]

Badges

Twitch badges work through their own tag.

[badge=subscriber]
[badge name=moderator]

See the Emotes section further down for how resolution, caching, and rate limits work under the hood.


Special Tags

Style Presets

Apply a saved preset by name. Create presets in the Style Presets editor (button in the properties panel).

[use=alert]Warning text[/use]

Save a preset called "alert" with tags like [color=red][b][shake], then use it anywhere with [use=alert]. Saves a lot of typing. Here's what a preset like that would look like:

Presets can nest up to 10 levels deep and are shared across all BBCode sources.

No Parse

Show BBCode tags as plain text instead of rendering them.

[noparse][b]this stays as text[/b][/noparse]
[plain][i]same thing[/i][/plain]

Without noparse, [b]text[/b] renders as:

With noparse, the tags are displayed literally as [b]bold text[/b] instead of being rendered.

Reset

Closes all open tags and goes back to default styling. Two ways to write it.

[b][color=red]Styled text[reset]Back to normal
[b]Bold[/all]Not bold

Everything after [reset] or [/all] returns to default font, colour, and size.

Newline

Force a line break without pressing Enter.

Line 1[/n]Line 2
Line 1
Line 2

Combining Tags

You can stack as many tags as you want. Nest them inside each other and they all apply.

[rainbow][wave]Rainbow Wave[/wave][/rainbow]
[b][color=gold][metallic speed=2]Gold Sheen[/metallic][/color][/b]
[fire][shake rate=10 level=2]Fiery Shake[/shake][/fire]
[electric][color=#89b4fa]Electric Blue[/color][/electric]
[rainbow][bounce]Rainbow Bounce[/bounce][/rainbow]

The order doesn't usually matter, but effects that move characters (wave, bounce, shake) should generally go on the outside, and colour/styling tags on the inside.


Global Tags

The Global Tags field in the properties panel wraps all your text automatically. Type your opening tags and the closing tags are added for you.

Put [rainbow][wave] in Global Tags, and your entire text gets wrapped in [rainbow][wave]...[/wave][/rainbow].

This is useful when other tools (like WebSocket) are supplying the text content. You can apply effects without touching the text itself.


Emotes

Drop any Twitch, 7TV, BetterTTV, or FrankerFaceZ emote straight into your text by name. The plugin does the resolution work for you, caches aggressively, and plays nice with the upstream APIs.

How resolution works

Resolution runs in a background thread so the UI never blocks. For each emote the plugin walks a journey, stopping at the first hit.

  1. In-memory cache (hit: zero network)
  2. Persistent disk cacheemote_urls.json survives OBS restarts
  3. Local scan of every cached channel set — any emote belonging to a channel you've already fetched resolves for free
  4. Channel hint from the tag if you passed one
  5. rootonline.de exact-name search (Twitch only, returns the emote ID directly)
  6. ivr.fi direct lookup (Twitch only)
  7. Prefix fallback — extracts the emote prefix, searches Twitch GQL for the owning channel, fetches that channel's set

Once a channel has been fetched once, every future emote from it resolves locally.

Caching

  • Channel emote sets cached for 7 days. Emote sets change rarely, so re-fetching every time is wasteful. Delete the relevant file in the emote cache folder to force a refresh.
  • URL cache persists across restarts. Once an emote is resolved, it never gets looked up again.
  • Atomic cache writes. If OBS crashes mid-save the file stays intact.

Rate limit behaviour

The plugin is polite to upstream APIs. Imagine 1000 streamers running it at the same time. It shouldn't hammer anything.

  • Per-provider rate limiting. Every API has its own mutex, minimum request spacing, and 429 cooldown.
  • Honours Retry-After. If an API tells us to back off, we back off.
  • User-Agent identifies the plugin. StreamUP-BBCode/1.0 so operators can contact or block us cleanly.
  • Duplicate dedupe. The same emote referenced 30 times in one text triggers one resolution, not 30.

Cache locations

  • Windows: %LOCALAPPDATA%\streamup-bbcode\emotes\
  • Linux: ~/.cache/streamup-bbcode/emotes/
  • macOS: ~/Library/Caches/streamup-bbcode/emotes/

Delete individual ivr_*.json files to refresh specific channels. Delete emote_urls.json to force every emote to re-resolve. Wipe the whole folder to start fresh.

Auto-wrap for Custom Size

Turn on Custom Size in the properties and long emote spams wrap to the next line automatically. Images wrap as atomic units. Text splits at word boundaries first, character boundaries if there's nowhere else to break. No [wrap] tag needed.


Variable Viewer

Hit the Variables button in the source properties to open the Variable Viewer. This is where you manage all your global [var=name] variables in one place.

You can:

  • See all variables and their current values at a glance
  • Edit inline by clicking on a name or value. Changes apply immediately to all BBCode sources
  • Add new variables with the + Add Variable button
  • Delete variables with the red X button on each row
  • Search by name or value using the search bar at the top

Duplicate variable names are blocked. If you try to rename a variable to something that already exists, it won't save.

Variables persist across OBS restarts. They're saved to your plugin config directory automatically whenever you make a change.

TIP

Variable values support full BBCode. Set a variable to [b][color=gold]VIP[/color][/b] and every [var=rank] in your text renders as bold gold "VIP". Useful for styled alerts without touching the source text.

Streamer.Bot Example

csharp
// Set text on a BBCode source
CPH.ObsSendRaw("CallVendorRequest",
  "{\"vendorName\":\"streamup-bbcode\"," +
  "\"requestType\":\"set_text\"," +
  "\"requestData\":{" +
    "\"sourceName\":\"My BBCode Source\"," +
    "\"text\":\"[b]Hello[/b] [color=red]World[/color]\"" +
  "}}", 0);

// Set a global variable (updates all BBCode sources using [var=username])
CPH.ObsSendRaw("CallVendorRequest",
  "{\"vendorName\":\"streamup-bbcode\"," +
  "\"requestType\":\"set_variable\"," +
  "\"requestData\":{" +
    "\"name\":\"username\"," +
    "\"value\":\"Andi\"" +
  "}}", 0);

// Get a variable value
CPH.ObsSendRaw("CallVendorRequest",
  "{\"vendorName\":\"streamup-bbcode\"," +
  "\"requestType\":\"get_variable\"," +
  "\"requestData\":{" +
    "\"name\":\"username\"" +
  "}}", 0);

Tips

Use the editor. Seriously, it's much easier than the properties text box. Syntax highlighting, live preview, tag browser all in one window. Open Editor in the source properties.

Nest tags freely. Bold, red, bouncing text is just [b][color=red][bounce]text[/bounce][/color][/b].

Use Global Tags for consistency. If every source should be the same font and colour, set it once in Global Tags instead of repeating it everywhere.

Save presets for things you reuse. If you keep typing [outline color=black size=2][shadow color=#000 x=2 y=2] on everything, save it as a preset and just use [use=my-style].

Copy tags from the reference. Right-click any tag in the Tag Reference sidebar to copy it. There are also "Copy Tag" and "Copy Syntax" buttons in the detail panel on the right.

Refresh on Active resets animations. Typewriter plays from the start every time you switch to a scene. Turn it off if you want animations to keep running in the background.
