Glossary
New to streaming tools? Here’s what the words in these docs mean, in plain language. Press Ctrl + FCmd + F to find a word fast.
Streaming words
Section titled “Streaming words”A pop-up that reacts by itself when someone follows, subscribes or tips, usually run by a service like StreamElements. The free elements in this app are not alerts: they play on cue. See How elements play.
Browser source
Section titled “Browser source”An OBS source that shows a web page or a web file from your computer. Every element the app adds to OBS is a browser source, with a see-through background around it. Streamlabs, XSplit, PRISM and Meld have the same kind of source. See Add to OBS by hand.
Chroma key and green screen
Section titled “Chroma key and green screen”A green screen is a flat, bright green background. A chroma key is a filter that removes one color, so that green turns see-through. Phone apps like CapCut use it to cut an element out of an MP4 that was saved on green. See Use your videos anywhere.
Hotkey
Section titled “Hotkey”A keyboard shortcut. In OBS you can give any source a hotkey in Settings → Hotkeys. If the app added the element to OBS for you, showing its source plays it, so a “Show” hotkey is an easy way to play an element whenever you want. See Hotkeys and Stream Deck.
Media source
Section titled “Media source”An OBS source that plays a video or sound file, like a video you downloaded from the app or a ready-made file from a pack (a stinger or a sticker, for example).
OBS Studio
Section titled “OBS Studio”The free, popular streaming app. Stream UI Fun Studio can add elements to it for you, as long as it’s version 28 or newer and runs on the same computer. See Add to OBS Studio.
Overlay
Section titled “Overlay”Anything drawn on top of your stream: a webcam frame, a follow tag, a chat box. Every element is a kind of overlay.
One layout of your stream in OBS, like “Starting soon”, “Just chatting” or “Gameplay”. Each scene is a collection of sources. When you add an element, you pick the scene it goes into.
Source
Section titled “Source”One thing inside a scene: your camera, a game capture, a picture, a browser source. Each element you add becomes its own source, so you can move, resize, hide or delete it in OBS.
Stinger transition
Section titled “Stinger transition”A short animation that plays when you switch from one scene to another. Some packs include them as ready-made video files. In OBS a stinger goes in Scene Transitions, not in a scene. See Set up a stinger transition in OBS.
Stream Deck
Section titled “Stream Deck”A pad of programmable buttons made by Elgato. Set a button to show an element’s source in OBS. If the app added the element, pressing it plays the element. See Hotkeys and Stream Deck.
Studio Mode
Section titled “Studio Mode”An OBS mode with two screens side by side: Preview (what you’re getting ready) and Program (what viewers see). When Studio Mode is on, the app puts a new element into your Preview scene first, so it doesn’t pop up live by surprise.
WebSocket server
Section titled “WebSocket server”A setting in OBS that lets other apps on your computer talk to it. Stream UI Fun Studio uses it to add elements and play them. Turn it on in OBS under Tools → WebSocket Server Settings. See Connect the app to OBS.
App words
Section titled “App words”Advanced
Section titled “Advanced”The switch at the top of an element’s Customize panel. Off (Basic) shows just the fields most people fill in, like your name and picture. On shows every setting: colors, fonts, timing, cursor, sound and size. It’s one switch for all elements, and the app remembers it next time. See Advanced settings.
Auto-fetch once a day
Section titled “Auto-fetch once a day”A switch in the Your channel panel. When it’s on, the first time you open the app each day it refreshes your follower counts, and your picture if you got it with Get it from …. It’s off until you turn it on. See Show your real follower counts.
One tile in the Elements grid. Some elements come with several cards, like a Light and a Dark one, and each card keeps its own settings. A copy you make is also a card.
A second card of the same element with its own settings, made with Make a copy in the editor. Handy for a second channel or a different look. See Make copies and reset changes.
Data folder
Section titled “Data folder”The folder where the app keeps your channel, settings, unlocked packs and the files OBS reads: %APPDATA%\Stream UI Fun Studio~/Library/Application Support/Stream UI Fun Studio~/.config/Stream UI Fun Studio. See Your files, backups and uninstalling.
Editor
Section titled “Editor”The screen that opens when you click a card: a live preview on the left and the Customize panel on the right, with Add to my stream at the bottom. Click All elements to go back. See Customize an element.
Element
Section titled “Element”An animated piece for your stream that you make your own: a follow tag, a subscribe bar, an intro, a socials bar and more. The app comes with 21 free elements, and packs add more. See Free elements catalog.
From your channel
Section titled “From your channel”A note under a field in the editor. It means the value (your name, handle, picture or count) comes from the Your channel panel. Change everywhere opens the Your channel panel at that field, so a change there updates every element. Just here lets you type something different for this one only. See How your channel fills in elements.
Handle
Section titled “Handle”Your account name on a platform, like the part after the @. Type it without the @ (the app removes it for you). For Discord, the app wants an invite link instead.
HTML folder
Section titled “HTML folder”A choice in More formats that saves an element as a folder you can add to OBS by hand, for example on a second streaming PC. See Add to OBS by hand.
In OBS and Refresh in OBS
Section titled “In OBS and Refresh in OBS”Badges on a card. In OBS means the app added the element to OBS. Refresh in OBS means you changed it while the app couldn’t reach OBS; it updates when the app reaches OBS again. See Change an element that’s already in OBS.
Live widget
Section titled “Live widget”An element from a pack that shows live data on stream, like your chat or a goal bar. In OBS (or another app’s browser source) it reads your public Twitch chat without logging in, which brings in chat messages, subs, cheers and raids. Follows, tips and other platforms like YouTube or Kick only reach it inside a StreamElements overlay. In the app’s preview it shows demo data. You add it to your stream as a browser source; there’s no video to download. See Use elements from packs.
Main platform
Section titled “Main platform”The platform you pick under Where do you stream? in the Your channel panel. An element made for one platform shows that platform’s count (a YouTube Subscribe Bar shows your YouTube subscribers). Elements that aren’t tied to one platform, or that cover several, show your main platform’s count. See How your channel fills in elements.
Play now
Section titled “Play now”A button on the It’s in OBS! screen, which appears right after you click Add to OBS (or Update in OBS). It plays the element in OBS straight away, which is handy for a quick test. It’s only on that screen, so to test later, hide and show the source in OBS. See Test your elements.
Profile chip
Section titled “Profile chip”Your picture and channel name in the top-right corner of the app. Click it to open the Your channel panel.
Your channel panel
Section titled “Your channel panel”Where you set your channel name, picture, platforms, handles and counts. Every element fills itself in from here. See Set up your channel.
Buying words
Section titled “Buying words”Gumroad
Section titled “Gumroad”The shop that handles checkout, payment and delivery for Stream UI packs. Buying always opens in your web browser.
Gumroad library
Section titled “Gumroad library”Your list of everything you bought, at app.gumroad.com/library. Sign in with the email you bought with to download your files again any time.
License key
Section titled “License key”A code that comes with some packs, in your Gumroad receipt email and library. It looks like XXXXXXXX-XXXXXXXX-XXXXXXXX-XXXXXXXX. Packs that need one ask for it after you unlock them. See License keys.
A label on products you already have in the Shop. On a product page the buy button becomes OWNED · OPEN IN APP, which opens its elements in the app.
What one purchase unlocks in the app: one or more elements or files. It comes inside the .zip you download from Gumroad, as a file whose name ends in “- for Stream UI Fun Studio.zip”. See Import and unlock your purchase.

Drop the whole download on the app window to unlock the pack. You don’t need to unzip it. Sharing the download shares your purchase, so keep it to yourself.
Video words
Section titled “Video words”16:9, 9:16 and 1:1
Section titled “16:9, 9:16 and 1:1”Video shapes. 16:9 is a normal wide stream or YouTube video (1920 × 1080). 9:16 is tall, for TikTok, Shorts and Reels (1080 × 1920). 1:1 is square (1080 × 1080). You pick one under Video size in More formats. See Choose a format.
Frame rate (fps)
Section titled “Frame rate (fps)”How many pictures per second a video shows. Videos are 60 fps, which looks smooth (GIFs are 30 fps at most). With Advanced on, More formats also offers 30 fps for smaller files.
A small looping animation that works almost everywhere, including Discord chat. GIFs have no sound.
A video format for editors like Premiere Pro, DaVinci Resolve and Final Cut. The app’s MOV has a see-through background.
The most common video format, great for phone apps like CapCut, TikTok and Instagram. MP4 can’t be see-through, so the app puts the element on a green screen or a color of your choice.
Transparent video
Section titled “Transparent video”A video with a see-through background, so only the element shows on top of your stream or footage. The app’s WebM and MOV videos are transparent.
The app’s main video format. Download saves a transparent WebM at 60 fps. It’s the best choice for OBS, Streamlabs and Meld.
Computer words
