Can iPhone 15 Pro record 4K 60fps Pro Res?

Yes, but with some caveats. 

Currently there are two ways to record 4k 60p pro res. 

1.  Use a 3rd party app such as Blackmagic camera and internal storage 
2.  Use an External SSD 

Using 3rd Party App (Blackmagic Camera)

The Blackmagic camera app is truly feature packed and costs nothing.

This is incredible considering that other companies developing similar apps have been increasing prices (i.e. filmic pro). 

The app even enables different codecs from ProRes Proxy all they way to ProRes 422 HQ. 

It's truly a no brainer to use their app if you want manual control over every aspect of filming. 

Just One Problem

The first issue that you will run into is limited storage. 

Just look at the max record times you get using internal storage:

 *for ProRes 422 HQ 4K 60p. Calculated after Subtracting 10 GB for system storage and assuming data rate of 7 GB per minute of footage. 

And this is with nothing else on your phone. No apps, no photos, nada. Yikes. 

And here are the prices and record times for external SSDs:

You can buy a top of the line 4TB SSD and a base 15 pro for $1299 and have 4 times more record time than shelling out $1499 for the 1TB 15 pro. 

Or if you just want to dip your toes the base 15 pro plus a 500 GB external SSD costs less than the 256gb 15 pro. 

So if you need long record times or just want to save money an External SSD is clearly the way to go.  

Using and External SSD

Plug and play. 

1. You just plug in the SSD and wait for the iphone native camera app to show "USB-C" in text at the bottom. 
2. Then you can select the pro res 4k 60p option from the top.
