Why should Periscope embrace landscape video. The answer to this question is one word. YouTube. 

The best Scopes are done by people who know how to engage their audience via video on a mobile device. We could spend months waiting for the best Periscopers to naturally emerge in the wild and eventually nail down how to get viewers to engage on the platform. Or we could enable a group of people who have spent years perfecting the skill of engaging and curating a mobile camera experience on a day to day basis.  The YouTubers. The users of a company whose very slogan is "Broadcast Yourself".

In many ways Periscope almost feels as if it should have been bought by YouTube and not Twitter. A little bit of proof that Twitter is on point with its innovation and acquisitions. 

Normal everyday people are unsure of what to say or afraid to engage with the camera when on periscope. But YouTubers know their audiences and are not shy in that experience. They know how to talk to an audience and how to engage them. We love to watch them. So here is the trick.

Periscope already allows you to save a Scope to your camera role when you are done. If Periscope embraced landscape mode it would allow YouTubers to every time use Periscope to initially record their videos while engaging with users in real time, then save that video to their camera role, and finally use that video for uploading to YouTube. Create once, while directly engaging your audience, and then easily syndicate! 

You can do this process currently but then you have a vertical video with black bars on both sides. And lets be honest, nobody wants to watch that. Vertical Video Syndrome is bad. And if you rotate your phone while on Periscope, as an attempted solution, you will have some very angry commenters coming at you pretty quickly because the comments do not rotate. A few simple additional UI changes when the screen is rotated could be a game changer. 

Content creators on all platforms do a lot of work. They have to syndicate content and manage audiences on multiple platforms. By periscope enabling this one feature it would enable YouTube content creators to more easily use one action for multiple platforms. In return, periscope would get next level high quality content creators for its platform. It's a no brainier.
