Video and replay
A still image is not always the best way to show off a design. When your work has motion in it, or you just want a reveal that pops in a feed, Brilliant renders it straight to video. This page covers two flavors: plain video export (MP4 and MOV) and Replay, a one-click animated reveal of your selection.
Both start the same way as any export: they work on your selection, not the whole canvas. Select a frame and its children come along.
Export a video
Video lives in the Export panel in the right toolbar. It appears when you have something selected. There's no keyboard shortcut and no command for plain video, since the options only make sense inline.
Select the elements you want to capture.
In the Export panel, set the format to MP4 or MOV.
Open the config (the gear) to reveal the video options: duration, FPS, quality, and codec.
Click Export, then pick a location. A progress bar counts frames as it renders, and you can cancel mid-render.
Video options
| Option | Values | Default |
|---|---|---|
| Duration | 0.5 to 60 seconds | 10s |
| FPS | 15, 24, 30, 60 | 60 |
| Quality | Low, Medium, High | Medium |
| Resolution | Same presets as image export (Original 1x through 4x, 720p through 8K, social and device presets, Custom) | Original (1x) |
The codec follows the format. MP4 gives you H.264 or HEVC (no transparency). MOV gives you HEVC with alpha or ProRes 4444, and only a MOV with one of those alpha codecs can carry a transparent background. Pick a transparent background with an opaque format and it quietly falls back to the canvas color.
Video captures animated shader fills in motion: a metaball, liquid metal, or holographic fill renders a real frame per tick. Everything else looks identical in every frame, since there's no keyframe timeline. If your design has no animated shaders, an image export gets you the same result faster.
Which platforms can export video?
This is the part worth reading before you plan a deliverable, because it's not the same on every OS.
| Platform | MP4 | MOV | Transparent video |
|---|---|---|---|
| macOS | Yes (H.264 or HEVC) | Yes (HEVC alpha or ProRes 4444) | Yes, via MOV |
| Windows | Yes (H.264 only) | No | No |
| Linux | No | No | No |
macOS has the full picture: both containers, both video codecs, and transparent output through MOV. On Windows you get MP4 with H.264 only, so the codec choice is fixed and the MOV option is hidden. Linux has no video export at all.
The practical takeaway: an MP4 for a social post or a message works on macOS and Windows. If you need a video with a transparent background (to composite over something else), that's macOS and MOV only.
Replay: a one-click reveal
Replay animates your selection into view, one element after another, each fading in with a shimmer pass. It's the fastest way to make a build feel alive for a post or a walkthrough, and unlike plain video it has a sensible default, so it doesn't need the full options panel.
Run it three ways:
Command palette: search for Export to Replay.
Right-click the selection and choose Export as, then Replay. This route renders at 2x for crisp retina output.
Export panel: set the format to Replay.
Replay files as an MP4 by default. On macOS you can switch its container to MOV for a transparent background. On Windows it stays MP4. The total length isn't a fixed duration: it comes from a per-element pace (default 150ms each) multiplied by how many elements are in your selection, so a bigger design plays longer. You can also add a short intro text card before the reveal.
Because Replay uses the same encoders as plain video, it follows the same platform rules: MP4 on macOS and Windows, MOV (and transparency) on macOS only. It's not available on Linux.
Replay animates whatever you've selected on the canvas. It's a reveal of your elements, not a recording of an AI chat session, so you don't need a chat open to use it. Point it at a finished layout and it builds that layout back up on screen.
Sharing what you made
Social: an MP4 at a square or story resolution drops straight into a post. Replay is built for exactly this: a design that assembles itself reads well in a feed.
Handoff: a short clip shows a teammate how a shader fill actually moves, which a screenshot can't. For a still handoff of the same work, see Import and export.
Transparent overlays: need the design to sit over other footage? Export a MOV with an alpha codec on macOS.
