Better resolution handle with 9:16 (Portrait) export

When using the 9:16 aspect ratio and exporting in 4K, the resolution is set to 1214 x 2160 pixels instead of the expected 2160 x 3840 pixels. This discrepancy results in lower output quality, which is noticeable and impacts the final product.

The resolution should correctly adjust to 2160 x 3840 pixels when selecting the 9:16 aspect ratio and 4K export option to ensure optimal quality.

Please update the software to correctly map the 9:16 aspect ratio to 2160 x 3840 pixels for 4K exports, ensuring high-quality output aligns with the selected settings.
