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](/Radarr/Radarr-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.
- 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](/Radarr/Radarr-collection-of-custom-formats/){:target="_blank" rel="noopener noreferrer"}
I suggest to first follow the [Quality Settings (File Size)](/Radarr/Radarr-Quality-Settings-File-Size/){:target="_blank" rel="noopener noreferrer"}. If you think the sizes are too big to your preference then stop reading and see if the other tutorials are helpful for you. :bangbang:
I decided not to add `Audio Advanced` Custom Formats to the encodes profile, being with encodes I prefer higher video quality. If you also want HD audio formats I would suggest to go for the Remuxes.
`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 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 with a score if possible, it's smarter to use the [{{ radarr['cf']['x265-hd']['name'] }}](/Radarr/Radarr-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 [{{ radarr['cf']['x265-hd']['name'] }}](/Radarr/Radarr-collection-of-custom-formats/#x265-hd){:target="_blank" rel="noopener noreferrer"} makes sure you still get the x265 releases.
