You can easily change the orientation of your snippets in 1SE to be vertical or horizontal.
For the best results, we recommend setting the snippet orientation to match the orientation you plan to use when mashing your video. This ensures a seamless, fullscreen look.
To change the orientation of a snippet, tap "Fit to Frame" on the snippet screen and select "Portrait" for vertical or "Landscape" for horizontal, then tap the yellow checkmark to save. 1SE also reads a clip's own orientation, so a landscape clip opens with "Landscape" already selected. On the mashing screen the equivalent control is "Orientation" — but that one is a single toggle rather than a picker: tapping it flips the whole mash between portrait and landscape, so there is no "Portrait" or "Landscape" to choose there.
