To resize your shot’s resolution bounds, go to the settings > Resize.
Original: size in pixels of your current shot resolution.
The top field is the length (horizontal) of the shot resolution.
The bottom field is the height (vertical) of the shot resolution.
Enbale the lock to keep the ratio of the size when changing either length or height value. The Presets allow you to quickly change the size of your shot.
Stretch image will adapt the image size to the new size of the shot. Keep this option disabled if you want to add or remove space while keeping the content size unchanged.
Tap on reset to set back the original resolution of the shot. You can choose between resizing the current shot or creating a new shot with the new size.
Resize: changes the size of your current shot, which can’t be undone. You can’t go back to the original resolution afterwards.
Create New Shot: creates and opens a copy of your current shot with your new resolution.
