# Glossary > What each Eddy word means, such as stage, Short, Sub-editor, house style and format, in plain English. Source: https://eddystudio.ai/docs/glossary/ ยท Written from the app's source code, last checked 3 November 2026; generated tables are rebuilt from the source on every build; not every behaviour hand-tested in the beta build Each word here is used somewhere else in these docs. The names in bold are the ones you'll see in the app. ## Your video ### Recording The raw video you give Eddy: a camera file, a screen recording, or a folder with both. You can also record inside Eddy. Eddy never changes your original files. ### Transcript Every word you said, with the time each word starts and ends. The speech models on your Mac write it. Cuts, captions and Shorts are all made from it. ### Scene A stretch of the video with one layout, such as your face filling the frame, or your screen with you beside it. Eddy labels each scene from what is on screen, and the label decides the layout. ### Stage One step of the progress bar while Eddy edits. The stages are Import, Rough cut, Edit, Render, Check and Deliver. [How an edit works](https://eddystudio.ai/docs/how-it-works/#the-stages) says what happens in each one. ### Long video The main edit of your recording. Its file name ends in `-long.mp4`. ### Short A vertical clip cut from your recording. One edit makes up to 3 Shorts, named `-short-1.mp4`, `-short-2.mp4` and so on. ## Changing an edit ### Chat Where you ask for a change in your own words. The AI you signed in with, ChatGPT or Claude, makes the change. ### Editor A chat that isn't tied to part of the video. It can work on the whole video. ### Sub-editor A chat you open on a scene, or on words you selected. It can change only those scenes and the layers in them, plus motion graphics, which are tied to your words rather than to a scene. ### AI Tools One-click edits in the AI Tools bar: Edit for clarity, Remove filler words, Remove retakes and Shorten word gaps. Style all scenes has no button; the chat and agents run it. ### Retake A part you said again because the first try went wrong. **Remove retakes** cuts the false starts, restarts and repeated phrases. ### Undo Changes to your edit (cuts, scenes, layers, motion graphics and the AI Tools) can be undone, and undoing a cut brings the words back. When the editor rewrites its plan for the edit, that isn't in Undo yet. ### Studio Sound Eddy's clean-up of your voice. It is always on and runs as the footage comes in. ## How it looks ### Your look Your colours, lettering and logo. Eddy uses them on every motion graphic it makes. ### Caption style How the captions look. The Captions panel has 4 styles: House, Clean, Classic, Bold. **House** is the default. ### House style How the whole edit looks and moves: its scene layouts, motion and timing. Unless you ask for one of your saved formats, an edit uses Eddy's built-in house style, which is **Not final**. A format you ask for replaces its timing and structure, in your own look. A house style learned from your own videos is **Not yet** in the app. The house style is not the same thing as the **House** caption style. ### Format The timing and structure of a video you like: the pacing of the cuts, the pauses, the layouts, the zooms and the captions. Eddy measures it from a reference you give it and saves it under a name. It never keeps the reference's colours, fonts, words, music or footage. ## Your Mac and agents ### Doctor sheet The app's health check. It is also where you connect agents, turn on remote access, send a support report and download the vision model. ### Speech models The models on your Mac that write the transcript. One comes with the app. The optional fast transcription model (about 5.6 GB) is much quicker on a long recording; it needs macOS 14 or later and downloads once, when you click **Download**. ### Vision model An optional model that lets Eddy look at each scene, still on your Mac. The vision model is about 3.9 GB, needs macOS 14 or later, and only downloads when you click **Download** in the Doctor sheet. ### Creator tools The 15 creator tools an AI agent such as ChatGPT or Claude uses to run Eddy for you. [For agents](https://eddystudio.ai/docs/for-agents/#the-creator-tools) lists them.
