How to Manage a Snippet

In the project's grid view, tap the thumbnail for the snippet you want to manage. In the detail view, tap the icon in the upper right-hand corner of the snippet thumbnail. This will bring up a menu with several options.

You'll have three options when sharing:

Save to Camera Roll: Save the snippet in your Photos app.
Create GIF: Create a GIF from your snippet and save it in your Photos app.
Share: Share the snippet.

Replace

Replace the snippet with a different photo or video.

Post to Project

Gives you the option to copy the snippet into other 1SE projects.

This option is not available on Storage Optimized projects.

Edit

Opens the snippet editing screen so you can make changes to your snippet.

Without the source video in your Camera Roll, your editing options are limited. You won't be able to modify or extend the length of your chosen video segment.
