Brio's window is a dock of panels. Each panel has a header bar with a grip and title (drag it to rearrange the dock) and, for some panels, its own action buttons on the right.
Open or close any panel from the Window menu. Panels are listed there alphabetically, with a check mark next to the ones that are open. A closed panel reopens in a sensible spot next to the panels that are already open.
Panels in this section:
- Viewer — the composition canvas
- Project — footage, comps, folders and project tabs
- Layers — the layer stack with switches
- Properties — every setting of the selected layer or comp
- Timeline — layer bars, keyframes, markers and the work area
- Graph Editor — value curves and easing
- Color & Swatches — colour, gradients and the project palette
- Align — anchor placement, align, distribute and offset
- Labels — named label colours
- Info — pixel values and file details
- History — the undo list
- Library — materials, HDRIs, presets
- Search — the command palette as a panel
- Mixer and Audio — sound levels
- X-Sheet — exposure sheet for frame-by-frame drawing
- Script Console — output of Brio Script runs
- Assistant — AI assistant
- Lesson — step-by-step lessons inside a project

Panel plugins add their own panels to the bottom of the Window menu, after a divider.
- AlignPlace a layer's anchor point on a box landmark, align and distribute layers, and stagger layers or keyframes in time.
- AssistantA chat panel where an AI model reads your scene and, if you allow it, makes changes for you — each reply is one undo step.
- AudioA dockable master level meter for the composition's mix.
- Color & SwatchesEdit the selected layer's fill and stroke colour, build gradients, and keep a project palette of swatches.
- Graph EditorShows animated properties as value curves so you can shape easing with bezier handles, numeric fields and presets.
- HistoryThe undo list — every edit in order, with click-to-jump to any earlier or undone state.
- InfoReads the pixel under the mouse in the Viewer and shows details about the composition and the selected layer's source file.
- LabelsNamed label colours for layers, keyframes, Project items and markers, with one-click select, solo, hide, lock and keyframe isolation per colour.
- LayersThe active composition's layer stack, with visibility, solo and lock switches, blend modes, track mattes and quick add buttons.
- LessonWalks you through the lesson stored in the open project, one step at a time, with a Show me button that sets up Brio for each step.
- LibraryA browsable grid of materials, HDRI environments, textures, objects, light rigs, particles, sprites, motion and text presets, built-in and your own.
- MixerA channel strip for every layer with sound, plus a master fader, for setting levels, pan, mute and solo.
- ProjectLists everything in the project (footage, compositions, folders and layer assets), with a preview of the selection and tabs for each open project.
- PropertiesShows and edits every setting of the selected layer — transform, shape, text, effects, Geo Ops, modifiers, masks, 3D, audio — or the composition when nothing is selected.
- Script ConsoleShows each Brio Script run — what it printed, how many changes it made, and any error with its line number.
- SearchThe command palette as a docked panel — search and run any menu command, effect, Geo Op, modifier or Shape Op by name.
- TimelineLayer bars, keyframes, markers, the work area and clip editing for the active composition, laid out against time.
- ViewerThe composition canvas, where you see the current frame and move, draw and edit layers directly.
- WorkspacesSaved arrangements of panels, with five built-in presets for different kinds of work.
- X-SheetAn exposure sheet for frame-by-frame drawing — one row per frame, one column per drawing layer.
