FAQ

What is StarFlux?

A Capstar browser editor for images, video, and audio — import, trim, sequence, and export locally in this browser.

How do I import media?

Drop, paste, Upload, Folder, URL, Mic, or open a project from the list above.

Can I start without a file?

Yes. Under the drop box pick Image, Video, or Audio. Image asks for aspect ratio and pixels — for pixel art you do not need anything to drop.

Where is my project saved?

Locally in this browser. Use Save and Projects after you import media.
