Frequently asked
What is a 4:5 aspect ratio?
Portrait feed format - takes more vertical screen space than square without being full-screen vertical. At standard quality that is 1080×1350 pixels.
Will my footage be stretched?
No - the source is scaled to cover the target frame and the excess is cropped from the center, so proportions are preserved.
