Your BlushDrop editor generally edits the clips in chronological order. 

Remember, you're charged per minute of video above the included 10 minute capacity. You can save a bit of money by not including clips you don't want to use. 

If a guest uploads a 10 minute clip but you only want BlushDrop editors to use 10 seconds of it, feel free to use a video trimming application on your computer to cut away the extra footage, then re-upload to your BlushDrop account. . 

Or just leave it all for your BlushDrop editors to sort out, along with a message to your support email provided when you sign up.
