Export
Trim to the best 30–60s first for a quick export. Saves as MP4 where your browser supports it, otherwise WebM (YouTube accepts both). Keep this tab open until it finishes — you can still play/tweak the preview while it renders.
Only process audio you own or have permission to use — you are responsible for how you use exported files.
