!!! note "Here we will provide some suggestions and try to explain why we recommend these settings. Adjust it to your liking, and keep in mind that it is only a suggestion. :bangbang:"
We will only cover settings that we think might be interesting or are personal preference, if you would like to see other settings covered, please contact us on [![Discord chat](https://trash-guides.info/assets/discord.png)](https://trash-guides.info/discord){:target="\_blank" rel="noopener noreferrer"}
1. Click on `Apply` and when everything is set up correctly, your Plex Media Server should be fully accessible outside of your network, so you can connect to your Plex server from outside. You may also need to configure port forwarding on your router. Detailed instructions are available [HERE](https://support.plex.tv/articles/200931138-troubleshooting-remote-access/){:target="\_blank" rel="noopener noreferrer"}.
When a change is detected in the source location for a library’s content, the appropriate library will be scanned. This function relies on the computer’s operating system providing the “something changed” trigger. Some operating systems don’t provide this trigger and content mounted via a network will also typically not work. If your library doesn’t automatically scan, you may have to set a periodical scan or do it manually.
In some cases, an operating system may not support this trigger - for example, if your storage is mounted on a network (SMB/NFS/Cloud Storage). In other cases, you may just find that your library doesn't automatically scan on its own. In these cases, you could consider using autoscan. IBRACORP (A Youtube channel we collaborate with) has a video explaining it in further detail.
When changes to library folders are detected, only scan the folder that has changed rather than scanning the entire content location. This works together with the normal Update my library automatically setting (and requires that setting to be enabled).
With this option enabled, when an item’s file is deleted from the drive, it will be removed from the Plex library on the next scan. Disabling this option keeps the item in the library with an overlay over the item’s poster when the item is removed.
*In my opinion Plex shouldn't touch your media files. Use Sonarr/Radarr to manage your media library. (For extra security I've set up Plex with Read Only access to the media library)*
![!Settings - Library - Run scanner tasks at a lower priority](images/settings-library-run-scanner-tasks-at-a-lower-priority.png)
On low-powered systems (e.g. ARM-based NAS devices), it can be beneficial to run scanner tasks at a lower priority than other tasks. This can help ensure they do not interfere with regular streaming.
Credits markers can be generated locally and/or retrieved via an online database. Online markers may not always exist, if this preference is set to 'both' then any locally detected markers are submitted anonymously back to the online database for future use.
!!! success ""
**Suggested: `both, try online first`**
*If you notice that the markers don't match your releases try `local detection only`.*
![!Settings - Library - Generate video preview thumbnails](images/settings-library-generate-video-preview-thumbnails.png)
This option creates a series of preview thumbnails from a media item when it is analyzed. These images are used by some Plex apps when you move back and forward in an app with the timeline scrubber. They’ll also be displayed in Now Playing when someone is streaming from you so that you can see where they are in the video.
The images are stored in your Plex database location (/config) so <u>be careful you don’t fill the drive :bangbang:</u>
#### Generate intro video markers
![!Settings - Library - Generate intro video markers](images/settings-library-generate-intro-video-markers.png)
You can choose to have TV episodes analyzed to try and detect when the “intro” occurs during playback. When detected, apps will then offer a `Skip Intro` button, allowing you to quickly jump over the intro.
This allows the server to analyze the audio stream to detect voice activity for movies and episodes. The analysis must be run on the video before it’s possible to make use of auto-syncing for that video.
!!! success ""
**Suggested: `as a scheduled task`**
*or*
**Suggested: `as a scheduled task and when media is added`**
Chapter thumbnails provide images in the chapter view on supported apps. They can take a little time to generate and consume very minor additional disk space.
Set the size of the main database cache, in MB. The default value is 40 and should be sufficient for just about every user. Increasing much beyond the default value is likely to only benefit users with extremely large media collections (as in, hundreds of thousands of episodes or music tracks).
!!! success ""
**Suggested: `1024`**
*or*
**Suggested: `2048`**
*These results are provided by users from our community*
*Accept and prefer secure connections when they’re available for a Plex app, but allow regular HTTP connections if the app doesn’t support secure connections or if one can’t be established*
For users with multiple network cards or systems such as NAS or Docker where there is always another network interface that Plex client applications may try to use to connect to the Plex Media Server, with this option you can ensure that your local Plex clients would only try that interface.
If you have Remote Access enabled and are having Plex automatically map the port (as opposed to specifying a port manually), then Plex Media Server has no control over which network interface is used for an automatically mapped port. Thus, it’s possible that Remote Access connections could come through an interface other than the one specified here.
If this setting is enabled, it prevents Plex Media Server from using or accepting the deprecated TLSv1.0 and v1.1 protocols, as well as legacy weak ciphers. May prevent older clients from connecting. The vast majority of users will have no reason to enable this option (and receive no benefit from doing so).
![!Settings - Network - LAN Networks](images/settings-network-treat-wan-ip-as-lan-bandwidth.png)
Allows incoming requests from this network’s WAN IP address to be treated as LAN requests in terms of bandwidth. This often occurs when DNS rebinding protection is in place and clients on the LAN cannot contact the server directly but instead have to go through the WAN IP address.
A comma-separated list of URLs (either HTTP or HTTPS) that will be published to plex.tv for server discovery. This can be very useful in a few cases: if you’re using a reverse proxy in front of the media server, or if your networking configuration is otherwise unique. For instance, if you have your own custom domain with a subdomain.
This feature can be enabled to allow your server to send events to external services. For example [Notifiarr](https://notifiarr.com/){:target="\_blank" rel="noopener noreferrer"}
This feature allows Plex Media Server to maintain high visual fidelity of content, by applying tone mapping to convert it to SDR when transcoding HDR content.
*Most HDR content will be in 4K resolution. If your platform has to use software transcoding to perform the tone mapping, then it may well struggle to convert 4K content in real-time, unless you’re running on a very powerful system.*
Plex’s tone mapping support should generally be able to produce good color mapping and help avoid the “washed-out” colors that occur when converting HDR content without tone mapping.
![!Settings - Transcoder - Tone Mapping Algorithm](images/settings-transcoder-tonemapping-algorithm.png)
Plex Media Server owners can choose which tone mapping algorithm is used when transcoding HDR content to SDR. Note: this feature is not yet available on Intel-based Windows systems.
!!! success ""
**Suggested: `hable`**
*This is a personal preference depending on what you prefer*<br>
*- hable: Preserve both dark and bright details better than reinhard, at the cost of slightly darkening everything. Use it when detail preservation is more important than color and brightness accuracy.*
The GPU or other hardware device that will be used for transcoding. The default setting will have the Auto option selected. If you have multiple devices capable of hardware-accelerated transcoding (e.g. both an integrated and discrete GPU), you can select a particular device.
!!! success ""
**Suggested: `Whichever device you wish to use for hardware transcoding`**
#### Maximum simultaneous video transcode
Set the maximum number of transcoding sessions that you will allow simultaneously. For instance, if you only want to allow two transcodes to happen at any one time (even if your computer is capable of more), you can set the value to 2.
!!! success ""
**Suggested: `However many your setup is capable of`**
*Besides being much faster at scanning and getting metadata, one of the benefits of the new agent is that all agent settings are set at the library level so that different libraries using the same agent can have different agent settings.*
1. This option creates a series of preview thumbnails from a media item when it is analyzed. These images are used by some Plex apps when you move back and forward in an app with the timeline scrubber. They’ll also be displayed in Now Playing when someone is streaming from you so that you can see where they are in the video.
Creating these images can <u>take a considerable amount of time</u>, <u>CPU resources</u>, and <u>increase the storage space used</u>. The images are stored in your Plex database so <u>be careful you don’t fill the drive :bangbang:</u>
In some cases, you may have more than one library and perhaps it doesn’t make sense to do this detection for all of your libraries. For any individual library, you can choose whether or not content in that library is included in detecting credits.
!!! success ""
**Suggested: `Enabled`**
*If Enable credits detection is disabled, then content from that library will not be included for analysis. Disabling for the library will also prevent the skip credits button from appearing and any skip credits behavior such as minimizing even if the markers have already been detected*

*Have you ever watched a TV show, and it starts playing that same minute and a half credits intro that you've already seen multiple times? Well, you can have your Plex Media Server analyze your TV shows to try and detect those introductions, and then let you skip through them with a single click!*
