Sets, props, soundtracks & sound effects
Beyond characters and voices, Popcorn supports four more element types. They all follow the same pattern: create once in an element chat, edit properties, save to library, @-mention in any movie.
🏠 Sets
Section titled “🏠 Sets”A set is a location or environment. Properties:
| Property | What it captures |
|---|---|
| Description | Overall summary — “a cozy independent coffee bar with hand-built furniture” |
| Atmosphere | Mood — “morning, warm, intimate” |
| Lighting | Light setup — “natural light through south-facing windows, golden hour” |
| Key features | Distinguishing details — “hand-painted mural, vintage espresso machine, mismatched chairs” |
Use sets when you have a recurring location across videos — a studio, an office, a brand-built space.
🎭 Props
Section titled “🎭 Props”A prop is a physical object that recurs in your videos. Properties:
| Property | What it captures |
|---|---|
| Description | What the object is |
| Appearance | What it looks like |
| Size | Scale relative to the user/scene |
| Material | Surface, finish, colors |
Use props for hero products (a bottle, a phone, a tool), recurring on-screen objects (the same coffee cup in every shot), or branded items.
🎵 Soundtracks
Section titled “🎵 Soundtracks”A soundtrack is a piece of background music. Properties:
| Property | What it captures |
|---|---|
| Genre | Style — “lo-fi hip-hop”, “orchestral cinematic”, “upbeat indie pop” |
| Mood | Vibe — “hopeful and morning”, “tense and driving” |
| Tempo | BPM range or feel |
| Instruments | Primary instrumentation |
Use soundtracks when you want a consistent sonic identity across a series — same track family for every episode of a channel, or a signature piece you want to keep using.
🔊 Sound effects
Section titled “🔊 Sound effects”Discrete audio cues — stings, transitions, punctuation. Properties:
| Property | What it captures |
|---|---|
| Description | What the sound is |
| Duration | Length |
| Intensity | How loud and present in the mix |
| Context | When it’s used — “caption appears”, “scene transition”, “product reveal” |
Creating any of these
Section titled “Creating any of these”The flow is identical to creating a character:
- Open the sidebar, click + next to the type you want.
- Popcorn opens an element chat.
- Tell Popp what you want.
- Iterate until the preview looks/sounds right.
Or in any movie chat, just describe the element naturally — “Use a coffee cup with hand-painted latte art as the hero prop” — and ask Popp to save it as a global element if you want to reuse it.
Reusing them
Section titled “Reusing them”@-mention any saved element in any movie chat. See @-mentions.
