What is ProRes: Its Definition and Workflow Explained

What is ProRes: Its Definition and Workflow Explained

One of the most preferred codecs in the production industry today is ProRes. For efficient playback, it has a combination of steep, high display quality and size. Furthermore, to the benefits of the ProRes codec, the ProRes RAW, which is labeled as the new kid on the block, contributes to the robustness of RAW videos. However, the videos that are compressed using Apple ProRes are still large and can occupy more disk space. Still, they allow a flawless editing experience as long as you use a good editing program. However, if you still do not understand what these all mean, do not worry because this article will guide you to understand what ProRes is as you read along until the end.

What is ProRes

Part 1. Understanding ProRes Format

Apple ProRes is a codec made by Apple way back in 2007. It is a popular video codec format due to its high-quality coding capabilities. This codec efficiently compresses the video content while reducing visual information loss. This is why making it is the preferred choice in post-production and professional video production.

Part 2. ProRes Versions and Codecs

There are different versions of ProRes, and each version varies on compression and image quality levels. Here is the list.

ProRes 422

ProRes 422 offers a good balance of size and quality and is suitable for extensive post-production and video editing needs.

ProRes 422 Low Throughput (LT)

This version of ProRes provides a greater ratio of compression that results in a smaller file size compared to the 422 version. Thus, ProRes 422 LT is a suitable project for your storage space concern.

ProRes 422 Proxy

This version has the highest level of compression. That said, it produces the smallest file sizes with the lowest display quality among the other versions. Prores 422 Proxy is normally used for extensive limits on storage and for offline editing.

ProRes 422 High Quality (HQ)

As its name suggests, it is a version that offers a higher image quality. However, due to the quality, it comes with a slightly larger file size than the ProRes 422. It's often preferred to use when better image fidelity is required.

ProRes 4444

ProRes 444 is another version that supports high-quality and visually lossless display in addition to the normal color information. This version is perfect for projects that require alpha channels and transparency support.

ProRes 4444 Extended Quality (XQ)

The highest quality a ProRes format could have is this 444 XQ version. It offers the least compression but with the best image quality that is suitable for projects that maintain the highest fidelity of image display.

ProRes 4K

ProRes 4K is the version that has the 4K resolution, providing a detailed and clear resolution.

Part 3. ProRes Workflow and Compatibility

ProPres Workflow

  • • You can record videos using a camera that supports ProRes.
  • • Import the file and edit it smoothly on video editing software.
  • • It provides seamless editing performance.
  • • Apply effects and color grading to enhance its quality.
  • • Render it when it is ready for export.
  • • Then, it can be distributed or broadcast.

ProRes Compatibility

  • • Apple ecosystem.
  • • Adobe Creative Suites.
  • • Avid Media Composer.
  • • And other popular editing software.

Part 4. ProRes Encoding and Decoding

The encoding and decoding of ProRes involve a compression and decompression process on video data. Here’s the overview of the codings.


  • • Data preparation- Prepare the video to encode by arranging it into frames. Then, manage the color information.
  • • Color quantization- The color information of the video is quantized and sampled for compression optimization.
  • • Bitrate control- Control the bitrate to influence the compression level. Higher bitrates mean a higher level of quality.
  • • Macroblocks and DCT- The frames of the video are divided into macroblocks. Also, DCT is applied to have frequency data from spatial data.
  • • Entropy encoding- The Huffman coding technique is applied for the entropy encoding after the transformation.
  • • File creation- After the compression and other metadata and settings are encapsulated for ProRes, it is prepared for storing.


  • • File reading- Retrieving of file from its source.
  • • Decompression- Reverse the compression by applying the corresponding decoding algorithm to ProRes.
  • • Color space and sampling reconstruction- Reconstruct the color space and sampling embedded.
  • • Frame rebuilding- Reconstruct the frame divided.
  • • Output- Save the decoded video data for playback and customization if needed.

Part 5. ProRes vs. Other Video Codecs

To see the difference between ProRes and the other video codecs, here is a table that shows ProRes vs. DNxHR, HEVC, AVC, etc.

Aspect ProRes AVC HEVC DNxHR AV1
Compression Medium-high High Veru high Medium-high Veru high
Size Large Small Small Large Small
Image Quality Lossless Good Better Lossless Good
Editing Performance Excellent Good Moderate Excellent Moderate

Part 7. FAQs About ProRes

Is ProRes the same as RAW?

No, it's not. ProRes is compressed, while the RAW is not.

Is ProRes better than a high-quality video?

ProRes is the preferred choice by many professionals because of its balanced quality, size, and editing efficiency compared to a regular high-quality video.

Is 256GB enough for ProRes?

It depends on the length of the video you record. An hour shot of ProRes video needs roughly 99GB of storage.


It is beneficial to have sufficient knowledge about Apple ProRes before you use it for video editing. Fortunately, this article brings you everything you need about it. And if you can’t handle a high-end video editor and converter, then use Tipard Video Converter Ultimate.
