You can mark your snippets as private to exclude them from your mashed videos so that you can comfortably share them on social media or with friends and family.
To do so, tap on the ellipsis icon (...) at the bottom right corner of the snippet thumbnail and select "Make Private."
Tap on "Make Visible" to revert this change.
Private snippets are excluded from mashes by default. To include them, tap on "Include Private" on the mashing screen and then confirm this action in the alert that will pop-up.
To exclude the private snippets from your mash, tap on "Remove Private" on the mashing screen.
NOTE: Private snippets are only hidden from your mashed videos; their thumbnails are not hidden from the calendar or day screen.
