How to Record ProRes Video to External Storage on iPhone 15/15 Pro

ProRes is a special video codec created by Apple to make your videos look their best, and it's been a part of Apple's video toolkit since 2007. ProRes's ability to compress video files while retaining exceptional image quality makes it stand out.

Imagine capturing all those precious moments with your iPhone 15 or 15 Pro, and you want your videos to be as sharp and detailed as possible. With ProRes, you can achieve that. It's like having your cake and eating it, too – you get the benefits of compression without a noticeable loss of image quality.

ProRes has reached heights with the latest iPhone 15 and 15 Pro update. In this guide, we'll show you how to harness the power of ProRes and record stunning videos directly to external storage. Say goodbye to storage worries and hello to top-notch video quality. Let's dive in!

Part 1. What is ProRes on iPhone

ProRes on iPhone is a special video codec that lets you capture and edit videos with higher color accuracy and less compression. This means your videos will look even more stunning and true to life. You can use ProRes on supported iPhone models, like the iPhone 15, iPhone 15 Pro Max, iPhone 14 Pro, and their predecessors.

ProRes works with all the phone's cameras, including the front one, but not in modes like Cinematic, Time-lapse, or Slo-Mo. Remember that ProRes videos take up more space on your device due to their higher quality.

What's cool is that you can record videos in ProRes right in the Camera app on your iPhone. Plus, you can edit them using apps like Photos, iMovie on iPhone, iPad, and Mac, or even professional software like Final Cut Pro. To get started, use iOS 15.1 or a newer version on a compatible iPhone model. This makes creating and editing stunning videos easier and more accessible than ever.

Part 2. How to Record ProRes 4K Videos to External Storage on iPhone 15/15 Pro

Apple's iPhone 15 Pro is a fantastic device, especially for those who love capturing high-quality videos. One of the standout features is the ability to record videos in ProRes format, known for its exceptional quality. However, there's a twist regarding the 128GB model, where external storage comes into play.

First, let's clear up some confusion. Apple doesn't mention this limitation on its website's tech specs page, but it's important to know. The 128GB model of the iPhone 15 Pro can record ProRes video, but only at 1080p and 30 frames per second when saving to its internal storage.

However, to enjoy the goodness of 4K ProRes, you'll need to get your hands on the 256GB, 512GB, or 1TB models. They can record 4K ProRes video natively to their internal storage.

Here's the exciting part: you can still enjoy 4K ProRes recording on the 128GB iPhone 15 Pro, but there's a catch. It's made possible by recording directly to an external storage drive, and this feature comes with the new iPhone 15 Pro, thanks to the A17 Pro chip and the new USB-C port. You might wonder why this limitation exists in the first place.

ProRes video files are quite large, and a one-minute 10-bit ProRes video gobbles up about 6GB of space in 4K. Apple aims for a smooth user experience; filling up the storage too quickly would be better.

How can you make the most of this external recording option? It's quite simple. Let's break it down:

Check Your iPhone Model

Ensure you have an iPhone 15 Pro with 128GB of storage. If you have a 256GB, 512GB, or 1TB model, you can record 4K ProRes videos internally, so there is no need for external storage.

Get the Right External Storage

You'll need an external storage device to make this work. However, only some drives will do. Apple's code reveals that the device should be formatted as exFAT or APFS. Unfortunately, the code doesn't mention specific disk speed requirements, but choosing a reputable, fast drive is advisable.

Activate ProRes Video Recording on iPhone

Connect your external storage device to your iPhone 15 Pro using the new USB-C port. Once connected, you can select the ProRes format, including 4K at 60 fps or 2.8K at 60 fps. Here are the steps:

  • To get started, open the Settings app on iPhone 15/15 Pro, scroll down and select Camera.
