Click on the vertical three dots to create a share when you are in a transaction footage, or watching footage on the videos page:
Click the option “Save Video Clip…”
A window will open with all the tools to create a share.
1 & 2 - the green bar shows what footage is included in the saved clip. You can click both ends of the green bar to drag the ends of the box, changing the start and end times of the video.
3 - The “Best Quality” button will toggle SD and HD footage.
4 - The scale can let you change the timeline view from 1 hour to 24 hours.
Give the shared video a name, ensure that you've chosen the correct times for your clip using the green box on the timeline, click on the share checkbox, add the email that you would like to send the clip to, add a message if you would like and then click save at the bottom right of the screen.
You do not have to wait for the save to complete - you can get back to work and it will automatically send when the save is complete.
