Sonarr V4+ introduces Custom Formats. These are much more advanced/powerful than the release profiles, although this also means a Custom Format can require more knowledge to set up or create.We've made 3 guides related to this.
Dolby Atmos is a surround sound technology developed by Dolby Laboratories. It expands on existing surround sound systems by adding height channels, allowing sounds to be interpreted as three-dimensional objects.
DTS-HD Master Audio is a multi-channel lossless audio codec developed by DTS that extends the lossy DTS Coherent Acoustics codec (DTS CA; usually referred to as simply "DTS"). Rather than being an entirely new coding mechanism, DTS-HD MA encodes an audio master in lossy DTS first, then stores a concurrent stream of supplementary data representing whatever the DTS encoder discarded. This gives DTS-HD MA a lossy "core" able to be played back by devices that cannot decode the more complex lossless audio. DTS-HD MA's primary application is audio storage and playback for Blu-ray Disc media.
FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3 - but lossless, meaning that the audio compressed with FLAC does not receive any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio.
Dolby Digital Plus, also known as Enhanced AC-3 (commonly abbreviated as DD+ or E-AC-3, or EC-3), is the successor to Dolby Digital (AC-3). It is a digital audio compression scheme developed by Dolby Labs for the transport and storage of multi-channel digital audio.
Digital Theater Sound (DTS) is a digital audio technology developed by DTS, Inc, which focuses on digital surround sound formats for consumer and commercial applications as well as theatrical purposes. Compared to the Dolby Digital standard, DTS uses four times less compression and digitizes audio sounds at 20 bits instead of 16 bits. This makes DTS-based audio richer in sound and more detailed than Dolby Digital-based ones.
From Wikipedia, the free encyclopediaAdvanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves higher sound quality than MP3 at the same bit rate.
Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end embedded processors. Opus replaces both Vorbis and Speex for new applications, and several blind listening tests have ranked it higher quality than any other standard audio format at any given bitrate until transparency is reached, including MP3, AAC, and HE-AAC.
Dolby Vision is a dynamic HDR format.It can offer better visual experiences relative to HDR10. The most significant difference is that it uses dynamic metadata which allows varying brightness levels within HDR content which enables filmmakers to have more precise control over the overall image appearance. HDR10 relies on static metadata which limits the HDR effect to a per-movie or per-episode basis.
HDR10+ improves upon HDR10 by making its metadata dynamic, allowing for it to change for each frame of video. This means every frame is adjusted to its own set of colors, brightness, and contrast parameters, making for a much more vibrant and realistic-looking image. Areas of the screen that might have been over-saturated with HDR10 will display their full contrast and detail with HDR10+.
? Any form of HDR will look significantly better than SDR on supporting equipment. The overall result will ultimately end up varying, though, based on your hardware and how the studio and filmmaker implemented HDR.
HDR10 relies on static metadata which limits its effect to a per-movie or per-episode basis. Because of this, it lacks the information for how the content should be adjusted for your specific display. The interaction between display capabilities, video metadata, and the ultimate output (i.e., the presentation of the video) is controlled by the display, which may result in quality that is ultimately not how was originally intended.
HLG or HLG10 is an HDR format created by NHK (JP) and the BBC that can be used for both video and still images. This format is backward compatible with SDR UHD TV, but not with older SDR displays that do not implement the Rec. 2020 color standards.
A hybrid release means any combination of sources (video + audio) and not a direct encode of a single source. Generally you can be sure that any hybrid that has been put together is the best quality release of a particular title.
For the software term, see Software remastering.Remaster (also digital remastering and digitally remastered) refers to changing the quality of the sound or of the image, or both, of previously created recordings, either audiophonic, cinematic, or videographic.
Depending on your renaming scheme Sonarr could potentially match renamed files AFTER they are downloaded and imported as BR-DISK,This is only a cosmetic annoyance until we come up with another way to solve this,Because this Custom Format is used to exclude downloading of BR-DISK, it is still behaving as intended.
x265 is good for 4k stuff or 1080p if they used the remuxes as source.If the media isn't source quality/remux, then there will be a loss of quality every time.Also, once you go x265, typically that file is done.It can't be changed to something else without a huge loss of quality.
So basically if you are storage poor and just need to save space, use x265.The catch is if you want best quality x265, you need source quality files, so you still have huge file sizes.If you want maximum compatibility and the option to change your files to something else later,then x264.It's all really dependent on specific situations for different people
Torrent sites sometimes set a torrent to be freeleech. This means that the download of this torrent will not count towards your quota or ratio. This can be useful when starting a new account or if you do not have the best ratio yet.
These groups take the original release and add their own language (ex. Portuguese) as the main audio track (AAC 2.0), What results after renaming and FFprobe is that the media file will be recognized as Portuguese AAC audio. It's a common rule that you add the best audio as the first track.Also they often even translate/rename the release name to Portuguese.
Most WEBDL from Streaming Services don't have the fallback to HDR10. What can result during playback is issues with weird colors (typically a green hue) when you attempt to play it on a non Dolby Vision compatible setup.
Some indexers strip out the release group which could result in LQ groups getting a higher score.For example, a lot of EVO releases end up stripped of the group name so they appear as "upgrades" and they end up getting a decent score if other things match
This Custom Format will recognize single-episode releases, instead of multi-episode or season packs, using Sonarr's built-in parser. Depending on your preference, you can give it a negative or positive score or skip adding it altogether.
This Custom Format will recognize multi-episode releases (e.g. episodes named with 'S01E01E02'), instead of single-episode or season packs, using Sonarr's built-in parser. Depending on your preference, you can give it a negative or positive score or skip adding it altogether.
