Part 1. What Is Apple ProRes Log?

ProRes Log is a video format that offers an image packed with more dynamic range. That translates to much more detail in the highlights and shadows compared to conventional video.

Log maximizes the data captured by the camera. It spreads the love equally between mid-tones, shadows, and highlights instead of just the mid-tones. What's more, Log has much more color information in the image. That offers enhanced flexibility with color grading, enabling you to create a stylistic look.

Without this dynamic range, fine-tuning colors and exposure could create unwanted, artificial artifacts and digital noise in the image.

At the time of this writing, only the following iPhones support recording in the ProRes Log format:

  • iPhone 16 Pro
  • iPhone 16 Pro Max
  • iPhone 15 Pro
  • iPhone 15 Pro Max

Part 2. Why Would the Apple ProRes Log Be Desirable?

First, Log isn't for everyone. It's for Pros who color-grade their video and do intensive edits to achieve a specific visual mood or style.

So, here's what makes ProRes Log unique:

Log Has No Local Tone Mapping

Many filmmakers are thrilled by ProRes Log's ability to style footage and make it look cinematic. The feature allows videographers to get the most out of their iPhones. In the Apple ProRes Log, there's no local tone mapping.

Local tone mapping happens when your iPhone selectively lightens or darkens certain sections of the image automatically. When shooting a video, you usually have to deal with scenes with a lot of contrast. For example, consider a dramatically lit interview. If you point the iPhone at it, an automatic process happens. You may or may not get the look that you're looking for.

Tone mapping works great for most scenarios. However, what if you want a contrasty-looking image? In ProRes Log, this automation is disabled, giving you complete freedom to create the look and feel you want.

Color, Sharpness, and Film-like Quality

Another interesting Log characteristic is its unprecedented ability to produce color, sharpness, and film-like quality. It's hard to recognize the footage and iPhone product. The automation of saturation and contrast isn't the only thing there is of mobile phone footage.

There's also a hard-to-miss digital sharpness in videos and photos shot on a phone. But in Apple Log, the subtle and less destructive look on details provides videos with a more film-like quality. You're also free to sharpen the footage in post-production.

Enhanced Post-Production Editing

As mentioned, Log footage offers more information to work with when color-grading. Its ability to retain details in shadows and highlights also provides more flexibility in editing colors in post-production.

Part 3. How to Turn on and Shoot ProRes Videos on Your iPhone?

The iPhone's Camera app isn't set up to utilize ProRes Log by default. Of course, there's a reason the device isn't set to take advantage of this superior provision right out of the box. First, Log takes up a lot more space; it could occupy 10x more than the regular formats!

Shooting regularly with ProPres or ProRes Log formats can fill your iPhone storage way quicker. The good thing is that you can always turn the features yourself whenever you want.

Here's how to turn on ProRes Log on your iPhone:

Step 1. Go to Settings, tap Camera, and select Formats.

Step 2. Enable Apple ProRes under "ProWAR & Resolution Control."

Step 3. Select the Log option within ProRes Encoding.

When recording videos in Log format on the iPhone, users often report that when shooting straight from the default Camera app, the iPhone tends to overexpose the image. Thus, (counter-intuitively to videographers) adjust the exposure to -1EV - underexposing the device by one stop.

To do that, tap the subject on your iPhone screen, then press and hold on it. That appears to be exposure and focus on the subject for consistency. To underexpose by one stop, tap the arrow at the upper section of the screen to change the menu or options at the bottom. Tap the plus and minus icons and dial down to -1.0.

Lastly, if you're shooting Log when it's bright outdoors, avoid blowing out your highlights. When shooting in low light, expose your subject properly, mindful of the shadows or darkest parts of the scene. Ultimately, you want to bump up your shadows minimally in the post, or you'll get too much noise.

Part 4. How to Repair a Corrupt Apple ProRes Log Video?

Like any other video file format, the Apple ProRes Log videos can also get corrupted. That can happen due to many reasons, including:

Part 5. Expert Tips When Shooting in the Apple ProRes Log

While shooting the ProRes Log video, experts recommend downloading a third-party Camera App. That could be the Moment Pro Camera App or Blackmagic Camera App. Using a third-party app helps in two ways:

  • Shooting in ProRes Log produces massive files
  • The Apps have extra exposure features that will help you get the most out of your production.

Using an External Drive

In the meantime, you can plug an external drive, a memory card, or an SSD drive into the USB-C connector. If you don't like having a dangling external drive or drive, consider using an additional app. An app will allow you to use a more manageable file size while still using Log.

Install a Third-Party Camera App

With an application like the Moment Pro Camera App, you have advanced features to work with. These include manual control over ISO and shutter speed, a waveform, and a histogram. These features are invaluable for achieving the perfect exposure.

The waveform and histogram help you ensure your footage isn't too bright (far right) or too dark (far left). Ideally, keep the levels in the center or Ideally, keep the levels in the center or slightly to the left to conserve highlight details.

Conclusion

FAQ

  • How large can the Apple ProRes Log files be?
    ProRes Log files are quite big. A 20-second clip can take up about 1 GB of memory, which might appear daunting. However, there are efficient ways to manage these chunky files without compromising quality. You can utilize a third-party Camera software or an external drive.
  • Does the iPhone 16 support the Apple ProRes Log?
    Only the iPhone 15 Pro, iPhone 15 Pro Max, iPhone 16 Pro, and iPhone 16 Pro Max support the Apple ProRes Log. On these iPhone models, you can choose between HDR, SDR, or Log color encoding when recording video in ProRes. To do that, go to Settings > Camera, then tap Formats. Turn on Apple ProRes, then tap ProRes Encoding.
  • Why does the ProRes Log appear grey and washed out?
    Log files right from the camera look flat and appear to have low contrast and saturation. Log footage retains more image information in the shadows and highlights. That allows for greater flexibility in editing contrast and colors in post-production.
