Resolution settings trade sharpness for file size and encode load. Many demos look fine at 1080p; 720p is enough for a simple menu walkthrough; 4K helps only when fine text must stay readable on a large display.
Practical picks
- 720p — quick tips, small uploads.
- 1080p — default for most lessons and tickets.
- 1440p / 4K — dense UIs on high-DPI screens, if Chrome and your machine keep up.
Choose the resolution in the extension settings before you start, then confirm the export still plays smoothly. Related: FPS settings.
