Frequently asked questions
How is height chosen?
Height is calculated proportionally from the source and adjusted to an even dimension required by the output encoding workflow.
Can I choose an arbitrary independent height?
No. This workspace exposes a width control and preserves the source proportions rather than offering a separate height field.
