What is That--The Interesting Blu-ray Audio Codec
Blu-ray audio codec is a way to store and transfer the audio data of Blu-ray disc. When speaking of it, you need to first figure out what is audio encoding and what is audio decoding.
Audio encoding is a method used to store the audio into the Blu-ray disc. You can apply a lot of formats to encode the audio into the disc. But you need to make sure that the audio encoding is supported by the Blu-ray player so that they can be read from the disc. While audio decoding or processing is where the audio being read so that it can be played through the amplifier and speaker. The decoding process can split the audio into multiple channels and send it to the speakers. So that's how audio codec works.
Audio encoding and audio decoding process may be the same thing but they still have something different. To understand these two processes will help you to better understand different Blu-ray audio codecs.

Linear PCM(LPCM)
LPCM, referred to as PCM Plus, is uncompressed audio encoding that applies a combination of values like sample sizes, sample rate, number of channels. It is a standard for Blu-ray. LPCM is a lossless audio coding that delivers CD quality sound, therefore it occupies huge disc space. Such audio codec is used to transmit uncompressed digital audio information via HDMI. LPCM supports up to eight channels of audio, which can provide encoding for 7.1 soundtracks.
Dolby Digital (DD)
Dolby Digital, also known as Dolby AC-3 or DD 5.1, can automatically provide a stereo version of the audio tracks so you can make your favorite movies or videos sound great on any devices. It is a lossy format that it compresses the audio to save space on the disc. Dolby Digital supports up to six channels of audio, which can provide surround sound limited to 5.1 and below. Such audio codec can be sent through HDMI or digital optical connections.
Dolby Digital Plus (DD+)
Dolby Digital Plus, known as DD+ or E-AC-3, is a audio encoding format. DD+ is an advanced surround sound audio technology that enables the Dolby Audio experience across home theaters, smartphones, operating systems and browsers. It supports 7.1 surround sound on Blu-ray discs, which allows for better audio quality. Please note that Dolby Digital Plus cannot be sent over coaxial or optical digital audio connections.
Dolby TrueHD
Dolby TrueHD is a lossless multi-channel audio codec which is used in home-entertainment equipment such as Blu-ray disc player. Dolby TrueHD supports up to 7.1 channels of high-definition audio, provide the most authentic surround sound experience available for your home theater.
DTS
DTS, known as DTS 5.1 or DTS Surround, is a popular home theater audio format that was developed in 1993 as a competitor to Dolby Labs. DTS is limited to a maximum of six audio channels for it compresses the audio to make the footprint smaller. It can provide surround sound codecs for 5.1, 6.1 and 7.1 setups.
DTS-HD High Resolution Audio
DTS-HD High Resolution Audio is an extension of DTS 5.1 and increases surround sound support to 7.1 channels. It is a lossy format which compresses the original audio to disc and loses some of the resolution in the process.
DTS-HD Master Audio

DTS-HD Master Audio is a combined lossless audio codec created by DTS, and commonly used for surround-sound movie soundtracks on Blu-ray disc. With upwards of 7.1 channels of discrete surround sound and connected via copy-protected HDMI cables, DTS-HD Master Audio is at the pinnacle of surround sound technology for home theater.
So now you may have a clear understanding of the Blu-ray audio codec and know the difference between such Blu-ray audio codecs. When you play Blu-ray disc, you need to find out what audio codecs your Blu-ray player support and watch your favorite Blu-ray movies with fantastic sound experience.
The Apple ProRes codec family provides an unparalleled combination of real-time, multistream editing performance, and impressive image quality preservation. ProRes RAW is based on the same principles and underlying technology as existing Apple ProRes codecs, and is ideal for High Dynamic Range (HDR) content creation in Final Cut Pro, Motion, and Compressor.
ProRes RAW brings the same great performance, quality, and ease of use to raw video that ProRes has brought to conventional video. When you store a clip in the ProRes RAW format rather than in a proprietary camera raw format, you get more control over the processing of the image, including demosaicing, linear-to-log conversions, and custom LUTs.
With ProRes RAW, you can import, edit, and grade video with RAW data straight from your camera sensor — without slowing down your edit. ProRes RAW also provides maximum flexibility for adjusting the look of your video while extending brightness and shadows.
You can render and export faster with ProRes RAW than you can with other raw formats—ProRes RAW is optimized for macOS and the latest Mac computers. And you can fit more footage on every card because ProRes RAW files are smaller than standard formats.
Data rate

You can choose between two ProRes RAW compression levels: ProRes RAW and ProRes RAW HQ. Both compression levels achieve excellent preservation of raw video content, with Apple ProRes RAW HQ providing additional quality at a higher data rate. ProRes RAW data rates can vary significantly based on image content, because the codec is designed to maintain constant quality and pristine image fidelity for all frames.
Performance
Raw video playback requires decoding the video bit stream and converting the decoded raw image. Final Cut Pro streamlines and optimizes this conversion process for Apple ProRes RAW files. When you use ProRes RAW with Final Cut Pro, you get the same real-time, multistream video editing performance you experience with Apple ProRes RAW as you do with standard media.
And with the Mac Pro (2019), the Afterburner card accelerates decoding and playback of multiple streams of ProRes and Pro Res RAW video files for even better performance.
View ProRes RAW on your Mac

After you install Pro Video Formats on your Mac, you can view ProRes RAW files with QuickTime Player and Quick Look. Since ProRes RAW captures high-dynamic-range data directly from the camera sensor, footage may look overexposed on the display of your Mac.
Because ProRes RAW is an acquisition format created by cameras and video recorders with RAW data straight from your camera sensor, it's not possible to create ProRes RAW files from video software. To export ProRes RAW files to other formats, use Final Cut Pro, Motion, or Compressor. You can't export ProRes RAW to other formats with QuickTime Player.
