From this tab you can share time-lapse video online or via messaging.

If you touch the main thumbnail for your time-lapse session the share file dialog will be displayed. Where you can share you new time-lapse video will depend on the apps you have installed.
Note: Sharing will use your data if you are not connected to WIFI and the video files can be very large, multiple gigabytes.

Note: Some apps have a file size limit and may also re-encode the video. For example WhatsApp will encode video and also has a size limit for videos it will except.

You can also share the zipped version of the time-lapse session from this page. You can zip up the image sequence on the Encoder Page.
The image sequence zip is useful if you want to import the project output into your Mac or PC video editor.
