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 mashing screen and select "Portrait" for vertical or "Landscape" for horizontal. Then, tap on the teal checkmark button to save your changes.
