Apple ProRes is a video format. Your first assumption may be that ProRes holds all the footage details and maximum amount of dynamic range-it does that, but its most notable purpose is something else. Thing.
Like Apple Pro Raw, this is a format created for editing. Video editors may convert captured clips to ProRes (or its rival Avid DNxHD) when importing captured clips into programs such as Apple Final Cut Pro, Adobe Premiere Pro, and BlackMagic Design’s DaVinci Resolve. Alternatively, you can use the outboard recorder to record directly to ProRes with many cameras.
But why use ProRes? One of the reasons is that the computer’s CPU is much easier and the editing process is much smoother than using the H.264 or H.265 format that the camera natively captures.
The interesting thing about ProRes is that Apple is rumored to introduce this format to the next iPhone 13 series, or the iPhone 13 Pro and iPhone 13 Pro Max. Explain what this means and why it’s a big deal.
What is Apple ProRes?
Apple announced ProRes in 2007 as part of its Final Cut Pro 6 editing software. The selling point at the time was “creating amazing HD quality with SD file size”.
This shows one of its important features. ProRes is a compressed format, but we aim to be “visually lossless.”
However, ProRes is not unique. A family of six quality standards, from the space-saving “ProRes 422 Proxy” to the ultra-high quality “ProRes 4444XQ”.
Which of these six formats you use depends on your image quality and file size / portability priorities. However, if you’re using hardware that can record ProRes natively, you’re limited to what’s supported. For example, the Atomos Ninja V external recorder supports ProRes 422 LT, 422, and 422HQ.
Below is a table of six ProRes standards that show how much space you can save compared to uncompressed files for curious people. We used figures from Apple’s ProRes white paper published in 2020. It is based on recording at 1080p resolution, 29.97fps.
What is the difference between 4: 4: 4 and 4: 2: 2? These are different ways to encode colors. 4: 2: 2 ProRes simplifies color information, but it’s still 10 bits, and in most cases provides enough fidelity to avoid obvious color banding. And, as you can see from these figures, even the highest quality ProRes files are much smaller than uncompressed files.
|4: 2: 2||Uncompressed 4: 2: 2 video||1,326Mbps|
|4: 2: 2||Apple ProRes 422 HQ||220Mbps|
|4: 2: 2||Apple ProRes 422||147Mbps|
|4: 2: 2||Apple ProRes 422 LT||102Mbps|
|4: 2: 2||Apple ProRes422 Proxy||45Mbps|
|4: 4: 4||Uncompressed 4: 4: 4 video||2237Mbps|
|4: 4: 4||Apple ProRes 4444 XQ||500Mbps|
|4: 4: 4||Apple ProRes 4444||330Mbps|
Why don’t you always use ProRes? Clips encoded in H.264 or H.265 are even smaller because they are designed to provide good quality at low bitrates. And this very style of encoding makes working with the editing suite a bit cumbersome and consumes the processor. If you are using an older laptop, you may not be able to handle 4K H.265 playback smoothly.
Use ProRes in the editing / production part of the process, then convert the final clip to something that can be played on your phone or TV via a USB stick. Probably H.264 or H.265 encoded. File. That said, YouTube actually supports ProRes 422.
Content authors can upload ProRes files directly to YouTube, but after passing the platform’s compression aperture, they end up in H.264 format.
Who is using Apple ProRes?
Those who edit video in one of the industry standard suites such as Final Cut Pro, Premiere Pro, and DaVinci Resolve will at least consider using ProRes.
This is a practical, high quality format to use when working with video projects. If you have a camera that can shoot uncompressed RAW video think You want to use it. However, if you’re dealing with high resolution captures and actual lengths, it will chew your SSD space at a terrifying rate.
Even if your camera only shoots 8-bit video, we recommend using 10-bit ProRes. First, the computer handles better than the files that the camera spits out. Even if the original footage color is only 8 bits, the edits you make can be processed with higher color fidelity. This means that the gradients will be smoother and the color banding will be less noticeable.
Why is ProRes on the iPhone so big?
As rumors suggest, this video format will be more mainstream than ever if Apple actually offers ProRes support on the iPhone 13 Pro and iPhone 13 Pro Max.
ProRes may be a common term among people who always make videos, but for example, for those who have a phone and want to start making interesting and well-created social media videos. It can be difficult to bother with things.
You don’t even need expensive video editing software to use ProRes. Anyway, iMovie has been supported since 2014 unless it’s in an MXF (Material Exchange Format) container. This is the file extension that appears at the end of the file name. ProRes videos are also available in the more familiar “MOV” format.
Apple hasn’t done anything technically groundbreaking here. You can use tools to transcode iPhone 12 MOV (H.264) and HEVC (H.265) to ProRe.s, but by removing the steps in the process, Apple is a beginner to these best practices from the beginning. Makes it much easier to adopt. .. Removing the extra compression steps also avoids potential image degradation. This is like recording a copy of a copy.
The adoption of ProRes is also a sign of Apple’s confidence in the video output of the iPhone. Video quality on mobile phones is not as competitive as still images, but it requires cranking out 30 or 60 frames per second, limiting the amount of computational work that can be done to relax the small sensor size restrictions. The iPhone still offers the best-in. -Class video.
How about Apple ProRes Raw?
You can’t talk about ProRes without mentioning the step-up format ProRes Raw. Introduced in 2018, it provides ProRes-style compression for live video captures. This is the same concept. The files are small and the CPU / GPU load is relatively low, which makes it easier to use than the alternative format CinemaDNG. There are others, but these are manufactured by camera manufacturers for use in their cameras.
ProRes Raw is a format that can be used with high-end mirrorless cameras made for video, or dedicated camcorders and outboard recorders. Several Atomos recorders, including Ninja V, support ProRes Raw. DJI’s Zenmuse X7 drone camera can also be recorded natively with ProRes Raw. And the resulting file size is actually comparable to the high-quality band of “non-raw” ProRes.
It’s supported by Adobe Premiere Pro, so you don’t even have to use Final Cut Pro to work with ProResRaw. However, at the time of writing, DaVinci Resolve is not.
The reason is very clear when you notice that DaVinci Resolve was created by Blackmagic Design, which created Blackmagic Raw, a proprietary compressed RAW video format. This is a license-free standard, unlike ProRes Raw. But from our point of view, as a camera user whose choice is dictated by the camera they ultimately buy, this little war does not benefit us.
However, DaVinci Resolve supports all versions except RawProRes. Blackmagic can choose to support ProRes Raw if the demand from users of this $ 299 suite outweighs their desire to promote their own compressed raw format.
