Periscope! Devs please note

This has been bugging me for ages. It needs sorting. I use Periscope a lot - I broadcast a lot. Indeed, while we were in New Zealand, I tried to Periscope every day. But it galls me. Periscope now, they say, supports landscape mode. That's the mode they should have started with, given that vertical video is an abomination. 

Yes, it's supported, but the implementation is terrible. The video below (assuming I get the linkage right) has had to be rotated in yet another app. And it still isn't right. This is what I got when I saved it to my camera roll. You'll see why I get annoyed.

 

So, Periscope... Please?
