Terms: the words apps' pages use
Each term page explains one word as the apps' pages use it, quoting two to four apps. As of 2026-09-25.
Many terms name the same feature differently from app to app.
Knowing the name an app uses is the quickest way to find the feature in its app.
Each term page quotes two to four apps and links to their pages on the register.
Some terms describe a feature, such as auto captions; others describe a plan limit, such as a watermark.
Each explanation stays close to how the apps' pages use the word, since the same word can mean slightly different things from one app to the next.
1Pages here
- 4K export — A 4K export renders a video at about 3840 by 2160 pixels, four times the pixels of 1080p
- AI actors — AI actors, or avatars, are generated people who present or act in a video from a script, without anyone being filmed
- AI dubbing — AI dubbing translates what is said in a video and replaces the spoken track with a synthetic voice in the new language
- Animated captions — Animated captions show a few words at a time and change them in step with the speech, often highlighting the word being said.
- Auto captions — Auto captions are captions an app writes by itself from the speech in a video, timed to the words, ready to style or correct.
- Auto reframe — Auto reframe moves the crop through a video as it plays, so the person or object that matters stays inside a new, usually taller, frame.
- B-roll — B-roll is footage placed over or between the main shots of a video, such as a close-up of an object being talked about, to show what is being said.
- Content scheduler — A content scheduler lets finished videos be set to publish on social platforms at chosen times, from inside the app
- Eye contact correction — Eye contact correction adjusts a speaker's eyes in video so they appear to look into the camera while they were actually reading a script or a screen.
- Noise removal — Noise removal separates speech from background sound, such as traffic, hum or room echo, and reduces the background so the voice comes through clearly.
- Repurposing — Repurposing means turning long content, a podcast, a webinar, an interview, into short clips for social platforms
- Text to speech — Text to speech reads typed words aloud in a synthetic voice, so a video can have narration without anyone recording it
- Text to video — Text to video is generating new footage from a written prompt, inside the app, instead of filming or finding stock
- Video resizer — A video resizer changes a video's canvas to another aspect ratio, such as 9:16 or 1:1, and leaves the framing inside it for the editor to set.
- Voice cloning — Voice cloning builds a synthetic voice from recordings of a real person, so new lines can be read in that person's voice without recording them.
- Watermark — A watermark is a logo or name an app places on exported videos, often on its no-charge plan, removed on paid plans

3Where the footage comes from
Upstream of an app feature like “Terms”, SceneMixer describes its own generation steps:
Every segment starts with a short header that sets the stage before the first shot: Location (a scene chip), Time, Weather, the Opening frame (what the first frame shows), Set dressing (what is in the room, and any background people) and Props (the objects the segment uses).

A short drama episode has two jobs: stop the scroll in its first seconds, and make the next episode feel necessary in its last.
