Recording video on a smartphone vertically.

It's about time I posted one of my world renowned whacky posts.

We've all seen videos on YouTube that are incorrectly recorded vertically with a smartphone and look terrible. Rather than forcing the user to rotate the phone horizontally, why does the smartphone not just internally rotate, crop and scale the image to 1080p (or whatever) when it's in the incorrect orientation?


Morning :)
 


Maybe because quality would be lower due to rectangular sensor and they don't want lower quality "HD" video to smear the brand?

Morning :D
 
How could we identify bellends if people didn't make portrait videos?

Good thread though hebbs

I want more now. Usually we get 5 or 6 whacky threads in a batch

Be funny if the phones did automatically turn the image 90 degrees, the bellends would constantly be turning it to try to correct it and eventually spontaneously combust

C'mon hebbs, this is good but doesn't quite match the vintage image/local paedo revelation

Well, a Samsung Galaxy s5 has 5312 x 2988 pixel sensor and the iPhone 6 3264 x 2448 pixels sensor.
So when recording 1920 x 1080p horizontally you get a mapping of 2.7:1 (s5) and 1.7:1 (iP6) sensor pixels to recorded Full HD pixels
Vertically you'd have to crop it in and get you'd get 1.55:1 and 1.27:1

Although the mapping is reduced when vertical as you'd expect, you'd still get at least one sensor pixel for each pixel that is recorded to the 1920x1080 frame.

I'd expect the visible difference would be negligible and certainly good enough for a smartphone.

5312 x 2988 pixels and a lens the size of a winnit!
