Here I will try to explain with some personal used examples how to make the most use of Custom Formats. That you can use to get a idea how to setup yours.
Custom formats are implemented within and have their impact controlled by Quality Profiles.
- The Upgrade Until score prevents upgrading once a release with this desired score has been downloaded.
- A score of 0 results in the custom format being informational only.
- The Minimum score requires releases to reach this threshold otherwise they will be rejected.
- Custom formats that match with undesirable attributes should be given a negative score to lower their appeal.
- Outright rejections should be given a negative score low enough that even if all of the other formats with positive scores were added, the score would still fall below the minimum.
First the basics where we going to explain where to setup the Custom Formats after you've added them, what we've explained in [How to import Custom Formats](/Radarr/Radarr-import-custom-formats/){:target="_blank" rel="noopener noreferrer"}.
The current logic can be found [HERE](https://github.com/Radarr/Radarr/blob/develop/src/NzbDrone.Core/DecisionEngine/DownloadDecisionComparer.cs){:target="_blank" rel="noopener noreferrer"} As of 1/19/2021 the logic is as follows
My suggestion is to create tiers of scores based on what things matter to you.
Personally I would only add the Custom Formats that do what you actually prefer especially in the beginning, including the [Releases you should avoid](#releases-you-should-avoid)

## Examples
Here I will show how to make the most use of Custom Formats and show some personal examples that I'm using. That you can use to get a idea how to setup yours.
All these examples make use of the [Collection of Custom Formats](/Radarr/Radarr-collection-of-custom-formats/){:target="_blank" rel="noopener noreferrer"}
If you notice that some scores are missing between the different Quality Profiles examples it's because I decided to be consistent with the scoring. Meaning a certain Custom Format has in every used Quality Profile the same score.
------
### Releases you should avoid
In my opinion this is a must for every Quality Profile you use, all these Custom Formats make sure you don't get Low Quality Releases.
- **BR-DISK** This is a custom format to help Radarr recognize & ignore BR-DISK (ISO's and Blu-ray folder structure) in addition to the standard BR-DISK quality.
- **EVO except WEB-DL** This group is often banned for the low quality Blu-ray releases, but their WEB-DL are okay.
- **Low Quality Releases** A collection of known Low Quality groups that are often banned from the the top trackers because the lack of quality or other reasons.
- **720/1080p no x265** This blocks/ignores 720/1080p releases that are encoded in x265 - More info [HERE](/Misc/x265-4k/){:target="_blank" rel="noopener noreferrer"}.
- **No-RlsGroup** Some indexers strip out the release group what could result in LQ groups getting a higher score. For example a lot of EVO releases end up stripping the group name, so they appear as "upgrades", and they end up getting a decent score if other things match
- **DoVi (WEBDL)** This is a special Custom Format that ignores DV for WEB-DL but together with the normal DoVi allows for other sources. WEB-DL from Streaming Services don't have the fallback to HDR(10), What can results in weird playback issues like weird colors if you want to play it on a not DoVi compatible setup. Remuxes and Bluray have a fallback to HDR(10).
You might even can consider to add [Multi](/Radarr/Radarr-collection-of-custom-formats/#multi){:target="_blank" rel="noopener noreferrer"} if you want to make sure you don't grab releases with often foreign audio.
I didn't add `Dolby Vision (Single Layer)` being most of the releases are already replaced by real `Dolby Vision` releases, If you still want to add it put it between `HDR` and `Dolby Vision` so they still can get upgraded.
Also I didn't add `10 Bit` being 4k releases are 99% 10bit anyway.
I decided not to add `Audio Advanced` Custom Formats to the encodes profile being with encodes I prefer higher video quality, If I want also the HD audio formats I would go for the Remuxes.
The Custom Formats we're going to use and scoring.
Make sure you don't check the BR-DISK, The reason why I didn't select the WEB-DL 720p is because you will find hardly any releases that aren't done as 1080p WEB-DL
The following workflow will be applied:
- It will download WEB-DL 1080p for the streaming movies you see more often lately.
- It will upgrade till Bluray-1080p when available.
- The downloaded media will be upgraded to any of the added Custom Formats till a score of 9999.
So why such a ridiculous high `Upgrade Until Custom` and not a score of `100` ?
Because I'm to lazy to calculate the maximum for every of my used Quality Profile and I want it to upgrade to the highest as possible anyway.

If you prefer 2160/4K encodes you might consider to enable HDR and set the `Upgrade Until Quality` to Bluray-2160p

- The downloaded media will be upgraded to any of the added Custom Formats till a score of 9999.
So why such a ridiculous high `Upgrade Until Custom` and not a score of `500` ?

`Media Management` => `File Management` to `Do Not Prefer` and use the [Repack/Proper](/Radarr/Radarr-collection-of-custom-formats/#repack-proper) Custom Format.
Being when you add a Custom Format what you prefer and you set it to something like `+10` it could happen that for example the `BR-DISK` will be downloaded (-10)+(+10)=0 and if your `Minimum Custom Format Score` is set at `0`.
Personally I wouldn't add the audio channels Custom Formats being you could limit your self in the amount of releases you're able to get. Only use this if you got specific reasons that you need them.
Using it with any kind of Remuxes Quality Profile is useless in my opinion being that 99% of all remuxes are multi audio anyway. and you can better score using the `Audio Advanced` Custom Formats
If possible avoid using the x264/x265 Custom Format with a score, it's smarter to use the [720/1080p no x265](/Radarr/Radarr-collection-of-custom-formats/#x265-7201080p){:target="_blank" rel="noopener noreferrer"} Custom Format.
Something like 95% of video files are x264 and have much better direct play support. If you have more than a couple users, you will notice much more transcoding.
Use x265 only for 4k releases and the [720/1080p no x265](/Radarr/Radarr-collection-of-custom-formats/#x265-7201080p){:target="_blank" rel="noopener noreferrer"} makes sure you still can get the x265 releases.
