There isn't a best setup, being that everyone has their own personal preferences. Some prefer high quality audio, others high quality video. Many prefer both.
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 an idea how to setup yours.
After you've added the Custom Formats, as explained in [How to import Custom Formats](/Sonarr/Sonarr-import-custom-formats/){:target="_blank" rel="noopener noreferrer"}.
You will need to set it up in the quality Profile you want to use/prefer to make use of the Custom Formats.
These screenshots are just examples to show you how it should look and where you need to place the data that you need to add, they aren't always a 100% reflection of the actual data and not always 100% up to date with the actual data you need to add.

Custom formats are 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.
Here I will explain how to make the most use of Custom Formats and show you some personal examples that I'm using. You can use these to get an idea on how to setup your own.
All these examples make use of the [Collection of Custom Formats](/Sonarr/Sonarr-collection-of-custom-formats/){:target="_blank" rel="noopener noreferrer"}
The reason why I have WEB 1080p merged with the 2160p is because some NF releases won't be released as 4k, but I still want to have DV/HDR releases.
If you want to do the same make sure you replace [x265 (HD)](/Sonarr/Sonarr-collection-of-custom-formats/#x265-hd){:target="_blank" rel="noopener noreferrer"} with [x265 (no HDR/DV)](/Sonarr/Sonarr-collection-of-custom-formats/#x265-no-hdrdv){:target="_blank" rel="noopener noreferrer"}.
`Media Management` => `File Management` to `Do Not Prefer` and use the [Repack/Proper](/Sonarr/Sonarr-collection-of-custom-formats/#repack-proper) Custom Format.
This way you make sure the Custom Format preferences will be used instead.
### Custom Formats to avoid certain releases
??? FAQ "How to use a Custom Format to avoid certain releases? - [CLICK TO EXPAND]"
For Custom Formats you really want to avoid, set it to something really low like `-10000` and not something like `-10`.
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`.
### Custom Formats with a score of 0
??? FAQ "What do Custom Formats with a score of 0 do? - [CLICK TO EXPAND]"
All Custom Formats with a score of 0 are pure informational and don't do anything.
### Minimum Custom Format Score
??? info "Minimum Custom Format Score - [CLICK TO EXPAND]"
Some people suggest not to use negative scores for your Custom Formats and set this option to a higher score then 0.
The reason why I don't prefer/use this is because you could limit yourself when some new groups or whatever will be released.
Also it makes it much more clear what you prefer and what you want to avoid.
### Audio Channels
??? info "Audio Channels - [CLICK TO EXPAND]"
Personally I wouldn't add the audio channels Custom Formats being you could limit yourself 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. You can get better scores using the `Audio Advanced` Custom Formats.
### Avoid using the x264/x265 Custom Format
??? tip "Avoid using the x264/x265 Custom Format - [CLICK TO EXPAND]"
Avoid using the x264/x265 Custom Format with a score if possible, it's smarter to use the [{{ sonarr['cf']['x265-hd']['name'] }}](/Sonarr/Sonarr-collection-of-custom-formats/#x265-hd){: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 of couple users, you will notice much more transcoding.
Use x265 only for 4k releases and the [{{ sonarr['cf']['x265-hd']['name'] }}](/Sonarr/Sonarr-collection-of-custom-formats/#x265-hd){:target="_blank" rel="noopener noreferrer"} makes sure you still get the x265 releases.
