Export your video

Mixture renders your composition frame by frame — using the same engine that draws the editor preview — and encodes it as an MP4 (H.264) file. The whole export runs in your browser; nothing is uploaded to render.

Open the export dialog

Click the Export button (the download icon) at the right end of the canvas toolbar. Export always applies to the composition you’re currently working on.

Review the output

The dialog opens on a summary of what you’ll get: the resolution, frame rate, duration, total frame count, and format. For a standard project that’s 1920 × 1080, 60 fps, and MP4 · H.264.

Press Export video to render the whole composition.

Note

If your device can’t encode video at the composition’s full size, Mixture falls back to the largest size it can encode and tells you in the dialog. Your project keeps its real dimensions — exporting later from a more capable device produces the full-resolution file.

Export a specific range

To render just part of the timeline, switch from Full video to Specific range and set the From and To times in seconds. The dialog shows how long the selected range is and how many frames it will produce.

Watch it render

While the export runs, the dialog shows a live preview of each encoded frame alongside a progress bar, the current frame count, elapsed time, and an estimate of the time remaining. You can Cancel at any point.

When it finishes, your browser downloads the MP4 automatically. On Chromium browsers you’re asked where to save before the render starts, and the file is written to disk as it encodes.

Or let an agent export for you

A connected agent can run the export too — ask it for the file and it renders the composition headlessly through the same engine and encoder this dialog uses, so the output is pixel-identical to an in-editor export.
