It converts an encoded digital file (MPEG4, for instance) into a \u201cnew version\u201d to reduce the size and to better meet the viewer\u2019s hardware and network resources. Transcoding is a necessary task to ensure that the content reaches the widest audience possible with different devices and Internet resources.&nbsp;This is the reason why YouTube and Netflix are kings of streaming, as they have massive computational resources to transcode plus Content Delivery Networks (CDNs) to reduce network latencies.&nbsp;<\/li>\n\n\n\n<li><strong>What is Direct Play? <\/strong>Direct Play is an important streaming technique where the file is sent directly to the client\u2019s device &#8220;as is&#8221; without alteration. The device can directly play a source media file as long as it is fully compatible with the client\u2019s capabilities, including container, bitrate, encoder, and resolution.&nbsp;<\/li>\n\n\n\n<li><strong>What is a Direct Stream? <\/strong>This is the process of extracting video and audio tracks and repackaging them into a compatible file container such as MP4. Direct streams are used when resolution and media type (H.264 or H.265) are compatible with the device, but the file container isn\u2019t (i.e, MP4, MKV, AVI, FLV, etc). This strategy puts little pressure on the CPU and doesn\u2019t compromise quality.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><meta charset=\"utf-8\">4K Plex streams can use any of the above methods. <\/h4>\n\n\n\n<p>Plex uses a client-server architecture. During streaming, the Plex server is the one transcoding or directly serving the media. The Plex server usually spends the most computational and networking resources, while the client only deals with compatibility and playback. <\/p>\n\n\n\n<p><strong>The below Plex Streaming 4K diagram shows the process to stream a 4K file. <\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"549\" src=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image10-1024x549.jpg\" alt=\"Plex Streaming 4K HDR\" class=\"wp-image-13024\" srcset=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image10-1024x549.jpg 1024w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image10-300x161.jpg 300w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image10-1536x823.jpg 1536w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image10.jpg 1820w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<ul id=\"block-86f90bdc-533f-44a3-bcd6-a77fa902fe9b\">\n<li>4K media files are usually stored in large volumes with fast disks, such as NAS (Network Attached Storage). The Plex Media Server may transcode the 4K file (if configured to) to adapt it to the Local or Remote Plex Client. In addition, the client can also direct-play it from the server.<\/li>\n\n\n\n<li>There are three paths (as defined in the previous section): transcoding, direct playing, or direct streaming. The two most popular are Transcoding and Direct Playing. Which one to choose? It depends on <strong>your requirements and&nbsp;resources. <\/strong><\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Understanding your Plex 4K Streaming Requirements and Resources. <\/h3>\n\n\n\n<p>The best approach to knowing which path to take is to define your requirements and&nbsp;resources. Are you trying to stream a 4K source file into a lower resolution, perhaps on a 1080p or 720p display? Or perhaps you would like to stream the 4K file on your 4K TV?&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Direct Play vs Transcoding Plex 4K Streams.<\/h4>\n\n\n\n<ul id=\"block-3ab0fea6-63f1-4373-a368-5b0d753fe4b4\">\n<li><strong>Usually, the best approach to stream a 4K file with Plex is to Direct Play it. <\/strong>This is, of course, only true if you have the network resources. Without these resources, there is a good chance of network latency, delays, and performance issues (thus buffering). In addition, Direct playing also requires more of your intervention. You&#8217;ll be preparing the 4K files, ensuring compatibility, and more. But if you manage it, your Plex streaming server will thank you for that.<\/li>\n\n\n\n<li><strong>It is better to direct-play a 4K stream to a local or a remote Plex client rather than transcoding it.<\/strong>&nbsp;Transcoding is a way to simplify compatibility at the end, but it does put A LOT of stress on the server, especially when transcoding concurrent 4K transcodes and H.265 (HEVC) content.&nbsp;Although transcoding is not always the right path, especially when your server&#8217;s resources are limited. But if your server can manage it, why not let transcode do its magic? <\/li>\n<\/ul>\n\n\n\n<div style=\"height:21px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"02\">2. Understanding H.264 vs. H.265 for Plex 4K Streaming (Codecs &amp; Compression)<\/h2>\n\n\n\n<p>Compression standards can make or break the deal when streaming Plex HDR.&nbsp;<\/p>\n\n\n\n<p>Media compression mechanisms (codecs) are mathematical algorithms designed to reduce the amount of information displayed on the screen. The purpose of compression is to reduce the size of the file and thus the need for more transmission bandwidth. <strong>Popular modern video codecs designed for streaming and broadcasting are H.264 and H.265.&nbsp;<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><strong>\ud83e\udde0 Fact! <\/strong>Both H.264 and H.265 encoding methods have their pros and cons, especially when used for 4K streaming on Plex.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><strong>T\u00ednh n\u0103ng<\/strong><\/td><td><strong>H.264<\/strong><\/td><td><strong>H.265 (HEVC)<\/strong><\/td><\/tr><tr><td>Compression Efficiency<\/td><td>Medium<\/td><td>High \u2013 50% less bandwidth<\/td><\/tr><tr><td>Compatibility<\/td><td>Universal<\/td><td>Limited device support<\/td><\/tr><tr><td>CPU Load<\/td><td>Moderate<\/td><td>Heavy (needs GPU\/modern CPU)<\/td><\/tr><tr><td>Best For<\/td><td>General Plex streaming<\/td><td>Advanced users with full chain HEVC<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">a. H.264 Codec.&nbsp;&nbsp;<\/h3>\n\n\n\n<p>H.264 (encoding standard) was designed to deliver good video quality at lower bitrates than previous standards, such as MPEG-4. Today, H.264 is popular across streaming providers mainly due to its high device compatibility.&nbsp;<\/p>\n\n\n\n<ul>\n<li><strong>Pro:<\/strong>  It supports media containers like MP4, MOV, and more.<\/li>\n\n\n\n<li><strong>Pro:<\/strong> A server with decent resources can encode media with H.264.<\/li>\n\n\n\n<li><strong>Con:<\/strong> 4K H.264 files are limited to 60 fps (frames per second).<\/li>\n\n\n\n<li><strong>Pro: <\/strong>H.264 is quite popular and widely supported. Almost any device today can play H.264.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">b. H.265 Codec.&nbsp;<\/h3>\n\n\n\n<p>The H.265 (HEVC) codec (encoding standard), provides much better compression rates than H.264. It lowers the bitrate to almost half while keeping the same video quality (in the human&#8217;s eyes). This better compression rate results in far smaller files, requiring less bandwidth for transmission. <strong>On average, an H.264 compressed 4K media file would require 32 Mbps bandwidth for smooth streaming, while the same 4K file compressed with H.265 would require 15 Mbps (less than half) bandwidth to stream it.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"640\" height=\"300\" src=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image2-12.png\" alt=\"Required bandwidth for 4K\" class=\"wp-image-13016\" srcset=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image2-12.png 640w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image2-12-300x141.png 300w\" sizes=\"(max-width: 640px) 100vw, 640px\" \/><\/figure>\n\n\n\n<ul>\n<li><strong>Pro: <\/strong>The difference in file size reduction with H.265 (HEVC), as compared with H.264 is 22% [source: <a href=\"https:\/\/9to5mac.com\/2017\/08\/15\/4k-video-hevc-codec-file-size\/\" target=\"_blank\" rel=\"noreferrer noopener\">9to5mac<\/a>].&nbsp;<\/li>\n\n\n\n<li><strong>Con:<\/strong> H.265 uses a complex codec mechanism. Decoding and encoding a file with H.265 will take a lot more computing resources, and it will be a much slower process than H.264.<\/li>\n\n\n\n<li><strong>Pro:<\/strong> H.265 compression allows resource-intensive resolutions such as 8K and a maximum frame rate per second of 300 fps. Obviously, as frame rates increase, so does the need for storage and bandwidth.<\/li>\n\n\n\n<li><strong>Con:<\/strong> Unfortunately, H. 265 is still not widely supported by devices and software.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>Although it makes sense to stream a 4K media file compressed with H.265 (HEVC), since it would require less overall bandwidth and storage (for now), the overall compatibility across playback devices for H.265 is scarce. Plus, encoding content with H.265 HEVC tends to be a lot more difficult and time-consuming. Decoding H.265 requires high CPU or GPU hardware resources.&nbsp;<\/p>\n\n\n\n<p><strong>If you intend to transcode your content, you are better off transcoding 4K H.264 content, not transcoding 4K H.265 content, due to the high computational demand. BUT, if all your playback chain supports H.265, and your content is already H.265 (HEVC), then streaming with this codec is a much better solution.<\/strong><\/p>\n\n\n\n<div style=\"height:21px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"Plex-Features\">3.

Server Requirements for Direct Play and 4K Transcoding on Plex.<\/h2>\n\n\n\n<p>To ensure the best streaming experience, it is important to have the right hardware, including a powerful CPU and a graphics card that supports 4K or HDR. Intel processors are known for their high performance and are often the preferred choice for streaming 4K content. <\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#d6ebfb\"><strong>For the best video transcoding experience, Plex offers support for various hardware acceleration technologies, such as Intel Quick Sync Video, which can greatly improve streaming performance. <\/strong><\/p>\n\n\n\n<p>A server without powerful resources and with high demand for content will likely have trouble delivering buffering-less playbacks. Your Plex clients will suffer from continuous video buffering and skipping as they wait for the server to catch up. <strong>Below are a few Plex 4K streaming requirements for the Plex server.&nbsp;<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">a. Get a decent processor for 4K direct-plays.&nbsp;<\/h3>\n\n\n\n<p>As a minimum hardware requirement, Plex recommends having at least an Intel Core i3 (or equivalent) or a faster processor on the server. However, an Intel Core i3 processor would not be capable of transcoding or attending to simultaneous streams, <strong>and not 4K streams.<\/strong>&nbsp;<\/p>\n\n\n\n<p>The following table, taken from the <a href=\"https:\/\/www.rapidseedbox.com\/vi\/blog\/plex-complete-guide\" target=\"_blank\" rel=\"noreferrer noopener\">h\u01b0\u1edbng d\u1eabn \u0111\u1ea7y \u0111\u1ee7 v\u1ec1 Plex<\/a>, describes the minimum requirements for streaming without transcoding to transcoding a single 4K HDR media file.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><strong>Transcode<\/strong><\/td><td><strong>Minimum CPU<\/strong><\/td><td><strong>RAM<\/strong><\/td><\/tr><tr><td>No Transcode<\/td><td>Intel \u201cAtom\u201d 1.2GHz<\/td><td>2GB<\/td><\/tr><tr><td>Single 720p transcode<\/td><td>Intel Core i3 3.0 GHz<\/td><td>2GB<\/td><\/tr><tr><td>Single 1080p transcode<\/td><td>Intel Core i5 3.0GHz<\/td><td>2GB<\/td><\/tr><tr><td>Single 2160p (4K) transcode<\/td><td>Intel Core i7 3.2GHz<\/td><td>2GB<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>As long as you are not transcoding 4K streams, you\u2019ll do fine with an Intel Core i3. <\/strong>But if you want to transcode multiple streams or 4K videos, your server hardware will need a robust processor and help from a GPU.

Bitrate depends on the codec, frame rate, and compression.<\/p>\n\n\n\n<p><strong>As a guideline:<\/strong><\/p>\n\n\n\n<ul>\n<li><strong>4K SDR (24\u201330 fps)<\/strong> needs <strong>35\u201345 Mbps<\/strong><\/li>\n\n\n\n<li><strong>4K HDR (44\u201356 fps)<\/strong> needs <strong>53\u201368 Mbps<\/strong><\/li>\n<\/ul>\n\n\n\n<p>To check your file\u2019s bitrate in Plex, click the three dots on the movie and select \u201cGet Info.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"639\" height=\"372\" src=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image5-11.png\" alt=\"Plex Streaming 4K bitrate\" class=\"wp-image-13019\" srcset=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image5-11.png 639w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image5-11-300x175.png 300w\" sizes=\"(max-width: 639px) 100vw, 639px\" \/><\/figure>\n\n\n\n<p>To achieve these bitrates and avoid buffering, use Gbit Ethernet technology (1 Gbps to 10 Gbps) at the server side. Wire your network with Ethernet CAT6 (Plex Server, TV, desktop, etc) to switch, instead of relying on WiFi.&nbsp;Consider getting a good upload speed (40 Mbps or more) to stream 4K content from the Plex server. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">c. Fast Disk for I\/O and enough storage.&nbsp;<\/h3>\n\n\n\n<p>If you are direct-playing a 4K stream, then you should consider having the following hardware: a fast HDD disk with a large buffer cache and short-seeking times. There are some HDDs on the market tailor-built explicitly for streaming, such as the <a href=\"https:\/\/www.toshiba-storage.com\/products\/v300\/\" target=\"_blank\" rel=\"noreferrer noopener\">Toshiba V300 (Video Streaming) Hard Drive<\/a>. Network-attached storage (NAS) is also an ideal solution for streaming, as it provides large volumes of storage and is suitable for streaming. NAS devices are widely supported by Plex Media Server.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">d. Don&#8217;t miss audio transcoding!<\/h3>\n\n\n\n<p><strong>Everybody gives much attention to video transcoding for Plex streaming, and most people forget the importance of audio transcoding. <\/strong>Audio transcoding is key to ensure a seamless streaming experience as well, especially when dealing with high-definition audio formats such as DTS or Dolby TrueHD, which may not be natively supported by all client devices. When Plex Server sees these formats, it will have to transcode the audio to a format that the client device can handle. This process relies heavily on the server&#8217;s CPU (not GPU!).<\/p>\n\n\n\n<p><strong>This audio transcoding can become a bottleneck!<\/strong> This is particularly true if the server is also managing heavy video transcoding tasks. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Tips to improve the Plex streaming experience related to audio. <\/strong><\/h4>\n\n\n\n<ul>\n<li>To reduce the server&#8217;s CPU load, consider adjusting the audio settings in Plex Media Server. One effective strategy is to prefer audio formats that are more universally supported, like AAC or MP3.<\/li>\n\n\n\n<li>In the Plex server settings, you can specify which audio codecs are preferred and configure the server to automatically convert less compatible audio tracks to more universally supported formats during the initial file analysis. <\/li>\n<\/ul>\n\n\n\n<div style=\"height:13px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\">\ud83d\udca1 Want to skip all the server setup and buffering headaches?<\/h3>\n\n\n\n<p class=\"has-text-align-center\"><strong>With a 4K-ready RapidSeedbox, you can plug and stream Plex like a pro \u2014 no server tweaking required.<\/strong><\/p>\n\n\n\n<div class=\"wp-block-group is-layout-constrained\"><div class=\"wp-block-group__inner-container\">\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-2\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-background wp-element-button\" href=\"https:\/\/www.rapidseedbox.com\/vi\/?blog=4k-plex-streaming\" style=\"background-color:#22c55e\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Explore Seedboxes for Plex!<\/strong><\/a><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<div style=\"height:13px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"04\">5. Best Devices and Clients for 4K Plex Streaming<\/h2>\n\n\n\n<p>Selecting the right client for playback will depend on what\u2019s in your Plex library. For instance, AppleTVs, Xbox, or Roku won\u2019t make a difference when most of your content is compressed with a video codec that your clients won\u2019t be able to play. <\/p>\n\n\n\n<p><strong>Below are the most important requirements for the Plex client when streaming 4K content.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">a. Compatibility.&nbsp;<\/h3>\n\n\n\n<p>To direct-play a 4K stream, your playback devices <strong>must support the media file (audio and video) codecs.<\/strong> Media players like TVs, streaming boxes, video consoles, VR, etc., supported by Plex native clients, would usually work fine (unless the app does not support 4K content!). Refer to the list of <a href=\"https:\/\/www.plex.tv\/media-server-downloads\/#plex-app\" target=\"_blank\" rel=\"noreferrer noopener\">compatible devices<\/a> to make sure your device is compatible. If you are using the Plex web browser GUI to stream 4K content, it is recommended that 4K content be encoded with H.264 video codec, and the video container is MP4.  <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">b. Use the right device.&nbsp;<\/h3>\n\n\n\n<p>Use the appropriate <a href=\"https:\/\/www.plex.tv\/apps-devices\/\" target=\"_blank\" rel=\"noreferrer noopener\">Plex streaming device<\/a> for direct playing a 4K stream. If you are streaming from a client computer, a GPU will help support the extra video processing load. Another great solution is using a streaming device designed for 4K HDR, such as the Nvidia Shield TV. This device will help you avoid all the buffering, lagging, and skipping. We recommend <a href=\"https:\/\/www.nvidia.com\/en-us\/shield\/\" target=\"_blank\" rel=\"noreferrer noopener\">Nvidia Shield Pro<\/a>; the&nbsp;best Android TV&nbsp;device on the market, hands down. This TV is especially good for Plex. <strong>Plus, a purpose-built 4K playback device, such as an HDR TV like Apple TV 4K, Fire Stick 4K Max, or Smart TVs with a native Plex client, can also work wonders.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"827\" height=\"629\" src=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image7-7.png\" alt=\"Plex Streaming 4K devices.\" class=\"wp-image-13021\" srcset=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image7-7.png 827w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image7-7-300x228.png 300w\" sizes=\"(max-width: 827px) 100vw, 827px\" \/><figcaption class=\"wp-element-caption\"><em>\u1ea2nh ch\u1ee5p b\u1edfi <a href=\"https:\/\/www.plex.tv\/\">Plex<\/a><\/em><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">c. Local Internet.&nbsp;<\/h3>\n\n\n\n<p>In<strong> <\/strong>most cases, <a href=\"https:\/\/www.rapidseedbox.com\/vi\/blog\/plex-buffering\" target=\"_blank\" rel=\"noreferrer noopener\">Plex 4K buffering<\/a> is due to slow network speed. To stream a typical 4K video at 20 Mbps<strong> (bitrate) without buffering from a remote server, you need at least double or more home Internet speed (starting from 40 Mbps).<\/strong> A 4K at 12 Mbps should work with a home Internet of 25-30 Mbps. Directly playing a 4K stream on Plex will inevitably consume data usage and bandwidth.<strong>&nbsp;<\/strong><\/p>\n\n\n\n<p>The closer you are to the Plex server serving the 4K stream, the lower the network latency and delay will be. If your client is on the same LAN, use a Gbit Ethernet (with CAT6 cables) to connect to the server. If you want to use WiFi, you\u2019ll have to optimize the range and avoid interference. When it comes to remote streaming, your ISP will play the biggest role.&nbsp;<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"05\">6.

Plex&nbsp;4K Streams: Tips and Hints.<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">a. Watch your 4K video container format.&nbsp;<\/h3>\n\n\n\n<p>Compatibility can be an issue when streaming 4K with Plex. You can help your Plex server save the transcoding overhead by changing your 4K video formats beforehand. Format containers hold compressed media along with metadata and additional descriptions. Popular containers can be AVI, MP4, MOV, or more. Again, due to compatibility, most 4K videos come in an MP4 container. Other video containers like MKV and AVI also support 4K, but they are less compatible with playback devices. If you have a 4K MKV or AVI, convert it using <a href=\"https:\/\/www.rapidseedbox.com\/blog\/guide-to-mastering-handbrake\" target=\"_blank\" rel=\"noreferrer noopener\">video encoders like Handbrake<\/a> to improve the success of 4K streaming playbacks.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">b. Only direct-play your 4K content if you are looking for pure \u201c4K streams.\u201d&nbsp;<\/h3>\n\n\n\n<p>Transcoding 4K content doesn\u2019t make much sense when all your playback devices support the 4K media content and your bandwidth and storage are &#8220;4K-ready.&#8221; Although this can be laborious, if you have different playback devices for your high-bitrate 4K content, you can also create different versions of the media. You may want to make (manually transcode) different encoding versions (H.264 or H.265) or change MOV or AVI to MP4, or even create a lower resolution for mobile screens. You can use a&nbsp;<a href=\"https:\/\/www.rapidseedbox.com\/blog\/guide-to-mastering-handbrake\" target=\"_blank\" rel=\"noreferrer noopener\">video encoder tool like Handbrake<\/a>&nbsp;to do the conversions. You can also test direct play 4K streams to remote clients, create a separate library of 4K content, and disable transcoding per library.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"857\" height=\"171\" src=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image9-4.png\" alt=\"Handbrake, convert 4K. \" class=\"wp-image-13023\" srcset=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image9-4.png 857w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image9-4-300x60.png 300w\" sizes=\"(max-width: 857px) 100vw, 857px\" \/><figcaption class=\"wp-element-caption\"><em>\u1ea2nh ch\u1ee5p b\u1edfi <a href=\"https:\/\/www.plex.tv\/\">Plex<\/a><\/em><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">c. Automate your 4K file format pre-transcodes.&nbsp;<\/h3>\n\n\n\n<p>Once you find the proper 4K format that directly plays into your devices, you can use automation tools like&nbsp;<a href=\"https:\/\/github.com\/mdhiggins\/sickbeard_mp4_automator\" target=\"_blank\" rel=\"noreferrer noopener\">Sickbeard<\/a>&nbsp;ho\u1eb7c&nbsp;<a href=\"https:\/\/www.rapidseedbox.com\/blog\/guide-to-mastering-handbrake\" target=\"_blank\" rel=\"noreferrer noopener\">Handbrake<\/a>&nbsp;with automation policies to convert the media files downloaded from third-party software into a standardized format. Software, like Sickbeard, can even attach tags (if the container supports it) with the appropriate metadata from database sites like TMDB. Additionally, you can use automation downloaders like <a href=\"https:\/\/www.rapidseedbox.com\/vi\/blog\/ultimate-guide-to-sonarr\" target=\"_blank\" rel=\"noreferrer noopener\">Sonarr<\/a> ho\u1eb7c <a href=\"https:\/\/www.rapidseedbox.com\/vi\/blog\/guide-to-radarr\" target=\"_blank\" rel=\"noreferrer noopener\">Radarr<\/a> to automatically download and replace your content. For instance, configure these tools to replace non-HDR content with 4K in certain containers. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">d. Set Plex Media Player to play video in the highest quality.&nbsp;<\/h3>\n\n\n\n<p>You can set the video quality to the maximum to improve the chances that your 4K content will direct play. If your content is 4K, then the following Plex 4K settings will indicate Plex to only play 4K. In the Plex Web Player, go to Settings &gt; Plex Web &gt; Quality. Selecting \u201cMaximum\u201d will guarantee that the client takes the best version from the video source (which should be 4K). Still, doing this does not ensure that the server will not transcode; The server will transcode the file if it detects an incompatibility or lack of resources.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"800\" height=\"470\" src=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image8-6.png\" alt=\"Plex 4K settings.\" class=\"wp-image-13022\" srcset=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image8-6.png 800w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/image8-6-300x176.png 300w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\"><em>\u1ea2nh ch\u1ee5p b\u1edfi <a href=\"https:\/\/www.plex.tv\/\">Plex<\/a><\/em><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">e. Subtitles may cause a Plex 4K stream to transcode.<strong>&nbsp;<\/strong><\/h3>\n\n\n\n<blockquote class=\"wp-block-quote\">\n<p>Even if the container, audio, and video resolution support the client\u2019s Plex application, incompatible subtitles can be a sign that Plex will trigger a full transcode \u2014 leading to buffering. Even if the container, audio, and video resolution support the client\u2019s Plex application, subtitle streams may not be fully compatible with the Plex client. If the server detects this incompatibility, it will \u201cburn in\u201d or \u201cembed\u201d subtitles within the video. Either action requires a full transcode of the streaming video.&nbsp;Again, a 4K transcode from a modest Plex Media Server will cause a 4K Plex stream to skip and buffer.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><em>\ud83d\udca1 <strong>Remember! <\/strong>Even if your 4K video and audio are compatible, subtitles alone can trigger full transcoding.<\/em><\/td><\/tr><\/tbody><\/table><\/figure>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\">d. Choose the Plex Player instead of the browser.&nbsp;<\/h3>\n\n\n\n<p>Avoid using the web-based interface when directly playing or streaming 4K with Plex. Instead, use the Plex native application for the specific client to ensure device compatibility. The application will perform much better than a web browser for streaming content. If you are unsure whether your device is compatible with H.265 (HEVC), then stream H.264 4K video content (instead of H. 265). If you are streaming Plex 4K video from the web browser, keep it to H.264 and MP4.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">e. If you intend to transcode your 4K streams, do the following.<\/h3>\n\n\n\n<p>Concurrent and simultaneous 4K content transcodes are resource-hungry. So, you\u2019ll need to empower the Plex server\u2019s CPU. Use GPU acceleration components to improve transcoding workloads and modern features like <a href=\"https:\/\/en.wikipedia.org\/wiki\/Tone_mapping\" target=\"_blank\" rel=\"noreferrer noopener\">tone mapping<\/a>. <strong>Plus, always transcode your media to H.264 (not H.265) and always keep a bitrate at 12 Mbps or 20 Mbps (not higher). A decent i5 quad-core or i7 should be capable of doing the job with the help of a GPU.<\/strong>&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">f. Ultra HD (UHD) 4K vs 4K HDR? <\/h3>\n\n\n\n<p>Trying to decide between Ultra HD 4K and 4K HDR? While both offer high-resolution displays (3840 x 2160 pixels, four times Full HD), it\u2019s important to understand the difference. UHD 4K delivers sharp, detailed images, ideal for streaming and gaming. 4K HDR goes further by enhancing contrast and expanding the color range, resulting in more lifelike, realistic visuals\u2014a clear sign of its visual superiority.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">g. Use a 4K Plex Seedbox.<\/h3>\n\n\n\n<p>Seedboxes are servers designed to seed torrents. A <a href=\"https:\/\/www.rapidseedbox.com\/vi\/?blog=4k-plex-streaming\" target=\"_blank\" rel=\"noreferrer noopener\">seedbox<\/a> is usually deployed as a cloud-based VPS within a high-speed data center and with high-performance resources, including CPU, memory, disk, and storage. A modern&nbsp;seedbox&nbsp;can also be tailor-built for 4K Plex streams. The remote cloud-based seedbox server has torrenting capabilities, the Plex Server app, and exceptional computational bandwidth and storage to allow online-sourced 4K streams. A seedbox may also come with torrenting automation tools like <a href=\"https:\/\/www.rapidseedbox.com\/vi\/blog\/ultimate-guide-to-sonarr\">Sonarr<\/a>, <a href=\"https:\/\/www.rapidseedbox.com\/vi\/blog\/guide-to-radarr\">Radarr<\/a>, SickBeard, and others. <br><br><strong>Learn more about this topic in:<\/strong> <a href=\"https:\/\/www.rapidseedbox.com\/vi\/blog\/best-seedbox-for-plex\" target=\"_blank\" rel=\"noreferrer noopener\">Best Seedboxes for Plex<\/a><\/p>\n\n\n\n<div style=\"height:21px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">8. 4K Plex Streaming &#8211; Final Words. <\/h2>\n\n\n\n<p>Congratulations!
