Offline, so any laptop can

The exporter renders every frame internally at 4K regardless of your screen or speed, and muxes audio with normalised loudness.

What 4K buys you

Bloom and thin lines keep their detail after YouTube’s compression, and the higher-bitrate encode makes gradients cleaner.

Aspect and quality

Lock 16:9, 9:16 or 1:1 and pick HD, 2K or 4K under Export & Record.
