Doubleback: Pre-Roll Dual Cam

You pressed record too late. Or you forgot. Or you thought it was recording and it wasn't. You missed the shot. If you film real life, you know what comes next. Something great happens, you weren't rolling, and now you're trying to recreate it. It never comes out as good. Not anymore. Doubleback is always holding the last two minutes of picture and sound. Press record after it happens and it's already in your clip. Perfect for journalists, freelancers, influencers, YouTubers, bloggers and vloggers. Great for wildlife, sports and kids. For documentary and reality TV filmmakers. For anyone who never gets a second take.
