The best way to get started is just selecting a couple seconds for the previous week. You can always go back and delete the ones you don't like. This gets you comfortable with 1SE and having fun right away!
Go into any day with a camera icon on it. This tells you there's video there you can select from.
Once inside a day, you have a bunch of great options. You can add a second (or two), write in your journal, or select your mood for the day. We're going to cover selecting a second of video. Tap either of the blue squares that say "ADD SNIPPET".
You'll now be taken to our media center which shows all the videos, and photos you have available. We prioritize videos from that day by putting them at the top. You can see the two videos for Monday, August 17th 2015 in the example.
Once you've select a video you want to use, you'll see our snippet selector screen. This allows you to do a ton of great stuff with your video. Like rotate (icon below the scissors on the right hand side), zoom in (beneath the rotate icon), and more.
You can use the arrows on the bottom left and right to go frame by frame in order to find that perfect moment. Don't forget, you can preview your second by pressing the tiny play icon on the bottom left in the orange rectangle.
Once you have that perfect moment found, simply tap the scissor icon on the top right to save the second.
Once you've selected your second, it'll be saved on your day and automatically favorited. Don't worry, you can always replace or delete a second by tapping the (...) icon on the bottom righthand corner of the thumbnail.
TIP: Add a caption or location info to help remember that moment.
