X265 Hdr EncodingGenerally speaking, it is not recommended to change these parameters, as the built-in presets offer a good range of options for common uses. Additional information To confirm if a specific processor supports it, check the datasheet and look for the HEVC related information. You don't need to declare --input-res or --fps with Y4M inputs for x265. The two-pass encoding didn’t reduce the file size as much as I expected and, in the case of x265, it increased the file size and not reduce it. Your FFmpeg will need to have been built with 10-bit (or even 12-bit) support. are a number of tools in the HEVC encoding toolkit that encoding and transmission of HDR. 265 and MPEG-H Part 2, is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H. HEVC was specifically created to provide UHD HDR deliverables with Apple supports 8-bit HEVC hardware encoding, and the High Sierra . Starting encoding Start encoding your new video with one click; Advanced workflows. MPC-HC is an extremely light-weight, open source media player for Windows ®. The chosen encoder must support these requirements to be fully compatible with the Dolby Vision specification. The first encode used x265 with a CRF value at 22 and the “veryslow” preset without BitSave preprocessing the file, which is generally known to provide for high-quality encoding at VMAF values of 95 or higher (visually lossless). Encode my original DV Profile 7 MKV (source. Tears of Steel provided a more consistent result in the 2 pass encoding even for VP9, that presented a very small 1 pass encoding, to begin with. support for interlaced encoding, and better encoder control to ensure correct rendering of HDR content. The program will then briefly demux the file to prepare for encoding. it can also be "constant" if you use --hal-hrd cbr parameter (in x264 days) So don't bother re-encoding your movies. 1 with my 4k stuff to avoid messing with the hdr. The result is a speed-up of up to 18% for encoding 4K HDR content, enabling improved throughput for companies using x265 and UHDkit for encoding. I am indeed encoding all of my DV Profile 7 MKV movies to x265 and outputting DV Profile 8. The Intel Xeon Scalable platform presents a revolutionary improvement in processor technology for the video encoding use-case. So I usually use Handbrake to encode all of my videos, but I can't find any understandable examples about how HDR encoding works. There is only one time to not use it. x265 is generally able to use more threads than x264 at a given frame size. Both encoders were configured to produce a similar visual quality and operate at a comparable encoding speed. 264, which is not wrong, but not accurate as well. when you open video that is encoded with hrd information in mediaInfo you'll see that files on blu-ray have "bitrate" property that shows "variable" value. For example, if you want to see the difference at insanely low bitrates, you might select a bitrate of 50 on each side, then hit the Show Changes. 7 The x265 HEVC video codec is available under the GPL* v2 license, and is integrated into several popular open-source multimedia frameworks such as ffmpeg*, HandBrake*, and VLC*. 265 hardware encoder in a professional grade portable streaming appliance. Have used Ffmpeg before but only to encode from 4k hdr h265 to 4k hdr x265 with CPU . ffmpeg -i -c:v libx264 -qp 23 ffmpeg -i -c:v libx265 -x265-params qp=23. 265/HEVC with Handbrake Best Settings. Also please don't use nVidia x265. On my desktop, the hardware encoding option is grayed out, forcing one to choose software. The Main profile of HEVC is equivalent to High in x265. Handbrake x265 10bit HDR settings . 94fps: Profile: Main 10 Tier: Main Bit Depth: 10-bit Encoding Mode: Average Bitrate (1-Pass) Target Bitrate: 18,000 - 50,000 kbps GOP: Closed. Seven 8Kp60 PQ-graded video sequences produced by Fraunhofer HHI and InterDigital were encoded with two open-source encoders: VVC VVenC, developed by Fraunhofer HHI, and HEVC x265. Basically, the syntax is: hdr10plus_parser. The Constant Rate Factor (CRF) is the default quality (and rate control) setting for the x264 and x265 encoders, and it’s also available for libvpx. " It means that you see the even and odd scan lines for a video frame at the same time. High Efficiency Video Coding (HEVC), also known as H. -x265-params: Specific parameters for HEVC encoding. HEVC was developed to enable encoding for 4K material in H. "Our continued enhancement of x265 with complex implementations such as the Intel AVX-512 optimization would not have been possible without support from Intel. The render starts, but, its really slow. Leave Level at Compatibility mode (4. 264 is a specification for compressing video, aka MPEG-4 part 10 or AVC; while x264 is a very high quality encoder that produces. - The APIs are similar to x264 APIs. For all other purpses -preset slow is you best bet. 2 AVX XOP FMA4 FMA3 LZCNT BMI1 [email protected]~$. The codec helps your computer. mkv -c:v libx265 -preset ultrafast -x265-params lossless=1 OUTPUT. Hello, Is there a solution to use 10bit x265 encoder? I don't find how i can full custom ffmpeg export, not only preset, and don't find it on this forum. I'm using ffmpeg (info below), and I've also tried the x264 encoder directly. mov -c:v libx264 -profile:v high422 -crf 20 -pix_fmt yuv422p output. Launch the program on your computer, drag your source file into the "Source" box of the program, click Automatic in the pop-up window, and then click okay. Concurrent to HEVC, Google developed VP9 as a royalty-free video . As Graphical User Interface (GUI), we suggest you to use x265vfw. It includes all tonmapping algorithms supported by ffmpeg at the time of release: clip, linear, gamma, reinhard, hable & mobius. Once you have that file, you can drop your source video in StaxRip, open the x265 encoder's options, then inside the VUI section, you'll find the entry for HDR10 Info File. It's 4:2:2 and no player supports this. These infos can be determined during encoding surely. I want to have an HDR YouTube video published, my source file is either an Apple ProRes or DNxHR using a chroma subsamplig 4:4:4 or full RGB, both 10bit, so the original source file has all what is needed in order to be encoded into a 10bit 4:2:0 H. x265 CLI is a command line software. Next-Gen Video Encoding: x265 Tackles HEVC/H. Wait for those 9000 frames to encode and after that you'll compare the video source to your encode test. By Chris Angelini published July 23, 2013. Performance Options¶--asm , --no-asm¶. Apple's suggested encoding ladder for H. 10 and 12 bit color for expanded detail and realism. For x265 encodings, HandBrake will also set the hdr-opt flag for you. Ultra High Definition (UHD, or 4K) with High-Dynamic Range (HDR)4. Higher values mean more compression, but at. 264 suffices) • If HDR provided, should provide at all resolutions. x265 is good enough for daily encoding, and its widely support 10-bit profile means that you can preserve color accuracy way better than 8-bit H. Here you can see the difference between the two best presets in my opinion: x265 Medium and my custom H. file rec:709 Question 1: How does one pipe correctly from ffmpeg to x265 ? Question 2: How can one make sure the cpus are all taxed? I have 16vcores, but im getting like 2-3% usage on all; Question 3: Any suggestions on the parameters to increase the quality?. For the test I used the following: libvpx-vp9 encoder (version 1. Not needing a disc authored? We offer a multitude of video encoding packages as well. You can get this tool and read its documentation here. Ability to accept analysis information from other previous encodes (that may or may not be x265), and selectively reuse and refine analysis for encoding subsequent passes enabled with the -refine-level. Access to technical information and. The shield plays back 4:2:0 HDR content (x265 10 bit) perfectly fine, no matter whether you feed it through an external HD (then it really depends on the player software you use) or whether you use Kodi or Plex. All encoders that support 10-bit encoding are also capable of HDR10 encoding. 264 streams (For backward compatibility some video content SHOULD be encoded with H. For x265, i read that 12 mbits is the max for 4. From hand-held computers, such as mobile phones and tablets, to large-screen televisions, modern chipsets and devices natively support HEVC decoding either in hardware or via software. FFmpeg command-line settings to enable VP9 Profile 2 and HDR EOTFs. Thankfully there is a simple answer. - Completly free and libre software, ensuring freedom for everyone. x265 and FFmpeg As mentioned above, encoding to x265 is easier in FFmpeg than using the x265 executable because you don’t have to pre-convert the files to YUV/Y4M. FastFlix keeps HDR10 metadata for x265, NVEncC HEVC, and VCEEncC HEVC, which will also be expanded to AV1 libraries when available. x265 only segfaults at the end of encoding, when freeing memory: `free(): invalid next size (fast)` The segfault happens with samples over at least 54 frames, but lengths such as 30 do not segfault. 0][64 bit] 10bit x265 [info]: using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4. Main10 would be used for 10-bit instead of High10. For this example I'll be using Scarface as it was encoded with x265 and HDR. High Efficiency Video Coding ( HEVC ), also known as H. 265/HEVC for 4K UHD or Full HD videos. Ability to accept analysis information from other previous encodes (that may or may not be x265), and selectively reuse and refine analysis for encoding subsequent passes enabled with the --refine-level option. rathousky Pls, i have been using Avidemux for many years to encode video to x264. 10-bit encoding definitely creates slight artifacts at low and medium bitrates during dark scenes and fades, 12-bit would probably eliminate that, just like with SDR content. You can disable all assembly by using --no-asm or you can specify a comma separated list of SIMD architectures to use, matching these strings: MMX2, SSE, SSE2, SSE3, SSSE3, SSE4, SSE4. 265 Definition: an advanced video compression standard capable of amazing visual quality with 50% bitrate savings. Required bandwidth for broadcasting in 4K; Recommended bandwidth for video encoding. Check the final look on your HDR monitor (if you graphic card allows you to do so); Render a specific EXR file sequence (or. Prior to encoding in Staxrip, you need to extract the dynamic metadata file, using the CLI tool hdr10plus_parser by Quietvoid. Here you can also try the best HandBrake replacement for encoding H. 0, which seems quite low, but that 30 was the max if i use high? Also, i noticed it was mentioning something to do with luma and stuff, which i dont understand, and i used 5. x265 Features Overview: - Provides next-generation compression and codec. This is my command to encode the video from frames: HTML Code: ffmpeg -i "frame (%d). If you're going to encode one video at the time, I recommend to buy a 8-core CPU. 264 is that it offers roughly double the compression ratio for the same quality. 265 UHDcode If you decide to spring for x265, take a look at the latest tools when you update. (alternatively finding a superfast (more than 90fps) codec/param for doing my encoding in a second step on ffmpeg, but it's a bit stupid) Image quality of libx265 10bit (for 8bit display and 8bit video source) is WAY BETTER than x265. Now we are going to set the X265 options. Using --preset slower is where the best features of HEVC generally kick in, but it'll still be a lot slower than x264 veryslow. Question 3: Any suggestions on the parameters to increase the quality? Use --crf instead of --bitrate. See All features how to install on Linux/Mac OSX. (less for more details) rect, no-amp (amp = no difference, sometimes it also crashed the encoding process) b-frames 4-6 no-fast-tskip sao or no-sao. In comparison to AVC, HEVC offers from 25% to 50% better data compression at the same level of video quality, or substantially improved video quality at the. The follow encoders support higher than 8-bit. I recommend not altering any of these as it will guarantee you will have an HDR output . Apple ProRes 422 and 4444 variants including XQ and PQ for HDR deliverables, DCP, IMF, MXF and Kakadu jPEG 2000 just to name a few.

Then follow the Handbrake guide to create high-quality and small H. Here are the settings that I typically use for encoding HEVC using FFmpeg for a file graded in SMPTE ST. Unfortunately CPU based encoders can not use high amount cores. 6 are usually good enough to mostly get rid of fine background noise in conjunction with x265's smoothing parameters (strong intra smoothing and sao). When playing back the video, the differences between the two are. Even if your source video doesn’t use the HDR color space, it compresses better. Are you using x265 for 4K HDR on Amazon Video, Ben?. All the x265 commands are explained HERE Now run a test, open cmd, type the path to your encoding folder and type the name of your bat file, the encode test should start right away. Utilizing some of the most advanced authoring tools available. I never included these parameters in my HDR encodes. Usually we confused x264 with H. Your decoder can decode picture just fine without it. 265/x265 video encoding on Handbrake, free download Handbrake 1. With SDR content, 12-bit encoding provides significantly better results (dark scenes and fades), but I wonder if it can somehow break the accuracy with HDR. Support for popular HDR formats-HEVC SDK. With x264 and x265, you can set the values between 0 and 51, where lower values would result in better quality, at the expense of higher file sizes. For adaptive-bitrate streaming, parallel encoding using UHDkit to multiple, simultaneous bitrate tiers dramatically improves efficiency compared to the use of multiple independent encoders. It functions as a multiformat video encoding application. No clue whether the data reported by MediaInfo can be simply copied, but you can report once you tried. I do not know if the HDR10\\+ LLC specifications allow. Like the x265 Encoder it is open source, and the latest 0. x265 Encoder is a piece of software enabling you to encode videos into the HEVC (High Efficiency Video Coding) format. Step 2: Drag the source file into the program. 2080 TISo what is faster at encoding 4K MP4 H. 264, and you can easily set a fixed QP for your entire encoding process with x264 and x265. x265 HDR encoding problem May 13, 2020, 06:54:30 AM Last Edit : May 13, 2020, 01:11:45 PM by jan. Are you using x265 for 4K HDR on Amazon Video, Ben? Reacher - screenshot tonemapped to SDR by MadVR; I'll give that a try, but I think it's chasing the wrong goal: rskip >0 gives an encoding speed improvement at the cost of coding efficiency, and lowering CTU to 32 lowers the latter further, whereas limit-tu 1 stops recursion based on the. In fact, the most recent codec performance comparison by the Moscow State University (MSU) proved MainConcept’s. HandBrake will automatically passthru mastering display metadata and content light metadata from the source video to to final encode. These results were obtained using the open-source encoders libvpx-vp9, x264, and x265. FastFlix is a simple and friendly GUI for encoding videos. However, x265 is waaay more complex with motion algorithms, meaning that accurately describing motion actually increases bitrate. This an essential technology for video streaming or mass encoding of personal footage to newer video formats (usually to preserve space). 264 and you don't have to suffer the poorly support 10-bit H. How to Encode HEVC: Handbrake Settings to Use. 1 MKV files (equivalent to MEL). With HamdBrake, my understanding was that although NVidia encoding is faster, the quality isn't as good and can result in bigger files, so CPU encoding is preferred for quality. With that out of the way, I'd like to share my experience with x265 encoding. Technically the RPU metadata would have to be recalculated for a compressed/downscaled reencode. In the examples below we use a statically-built ffmpeg with 10-bit support. 265 (SDR must be provided; not clear if H. Shortly after starting, it gets to be several seconds PER FRAME. 940 -pix_fmt yuv420p10le -c:v libx265 -c:a aac -strict -2 -shortest -y -x265-params "colorprim=bt2020:colormatrix=bt2020nc:master. Can you create an option to select x265/h265 encoding over x264 as files are growing in size do to 2160p and trueHD, x265 would reduce file size to over 50% thus reducing over all footprint on NAS or array considerably. 3 or greater) under the hood for the heavy lifting, and can work with a variety of encoders. HEVC allows 10 bit encoding so if the source is encoded using this parameter then it will definitely be better quality than the h. Footloose presented an interesting encoding exercise. The software upgrade will include UHDcode, a very handy HEVC decoder that you can use to render video. If you need to learn how to produce HDR with FFmpeg, check out the article at bit. For mainstream systems, just let x265 handle it automatically. It basically confirms that NVIDIA GA102 and GA104 GPUs will decode the new AV1 open format up to 10. 265-compatible encoder must conform to ITU-T H. I also compiled libvmaf (version 1. Ability to accept analysis information from other previous encodes (that may or may not be x265), and selectively reuse and refine analysis for encoding subsequent passes enabled with the –refine-level. Answer (1 of 4): If both files are the same size then HEVC will show better quality. Limitations HandBrake will only handle HDR10 metadata. For more advanced encoders that may have beefier CPUs, or even servers, this section may interest you. Diversified Video Solutions offers an array of disc authoring and video encoding solutions. and But adding the HDR10+ option you could encode with BT2020 colorspace and 10bit deepth. - x265 10-bit encoder - Mastering display characteristics metadata added to file. 265 in a faster and easier way:. It is available as a command-line app or a software library, under the terms of GNU General Public License (GPL) version 2 or later; however, customers may request a commercial license. You may use our build script to make your own, or follow the guidance on the FFmpeg site. 265 By Chris Angelini published July 23, 2013 Last month, the HEVC/H. Enhanced HDR10 encoding with HDR-specific QP optimzations for chroma, and luma planes of WCG content enabled; use --hdr-opt to activate. If you want to recreate the same execution environment: I used Docker to build it so you can recreate the exact same environment using my Dockerfile which can be. 264 encoding, with full support for the full range of both sets of specifications.

I know of no SoC that supports hardware decoding for HEVC profile 2. There is an option --input-depth Specify input bit depth for raw input but nothing for output bit depth. HEVC support is widespread across a variety of consumer devices today. HandBrake has updated with the H. 265, or High Efficiency Video Coding, is a new video coding standard that specifies how to decode video. This article delves into that experiment and shares the results of Christian’s research. There is very little difference in visual quality, with a slight advantage to H. 0 or later version on your PC as it added full support for 4K codecs H265 and VP9. x265 Intel QuickSync Apple Video Toolbox HandBrake will automatically passthru mastering display metadata and content light metadata from the source video to to final encode. X265 Parameters I use this mainly when I have a high quality original encoded video, and want to duplicate the encode settings for it. Completly free and libre software, ensuring freedom for everyone. Enhanced HDR10 encoding with HDR-specific QP optimizations for The bitrate target for x265 can now be dynamically reconfigured via the . hevc stream to the file metadata. This will extract the dynamic metadata content from your source. 265 that support up to Main 10 Profile Level 5. It's only recently been possible to actually use x265 for transparent encodes, previous versions of x265 removed film grain/digital noice to such a degree that the quality was worse than x264 at equivalent bitrates. Step 1: Install and run Handbrake. Some issues to consider when looking at cloud encoding using GPU. If you're going to gaming+encoding, you can buy 12-core CPU and play games with 4 cores and encode videos with other 8 cores. Most cloud services do not focus on 400Gig source files in 4k HDR. bitdepth (clip, bits=16) clip = core. Pls, i have been using Avidemux for many years to encode video to x264. The correct syntax to enable lossless mode for x265 encoder in ffmpeg is -x265-params lossless=1 (you need to append =1). x265 is used in several free video converters like Handbrake, Xvid4PSP, StaxRip, RipBot264, MEGUI, Xmedia Recode, etc. Today, the most popular open source encoder for HEVC is x265. I have followed some answers listed here, reviewed lots of different approaches, tried out many different commands without success, colors aren't right when using only FFmpeg, to much red, when using only Adobe to encode into H. 1 it includes for tonemapping of HDR video to SDR. I recently started using StaxRip to compress some 4K HDR movies, since I heard StaxRip can properly encode 10-bit HDR. First things first, you need a good cpu for 1080p x265 hdr encoding and a beast of cpu for 4k x265 hdr encoding, otherwise you'll have to wait days for an encode. Let's break down what we are throwing into the x265-params : hdr-opt=1 we are telling it yes, we will be using HDR; repeat-headers=1 we want .

You can run multiple encoding instances at once. 4K Encoder (VC-970) Specification②. 265) video compression format developed by the Joint Collaborative Team on Video Coding (JCT-VC). By default, an x265 (HEVC) 8 vs 10-bit comparison is selected, at 400kbps and an encoding preset speed of "Slow". Apply slight digital noise reduction: Code: clip = core. Atmos-4,蓝光高清网分享给每一个高清爱好者,提供4K高清电影,1080p高清电影,蓝光原盘,3D高清电影,BBC纪录片,高清演唱会,vr视频等资源,4k蓝光原盘电影发布与全球破解小组同步发布,给每一个高清爱好者带来至臻高清的观影体验. The x265 encoder employs a wide variety of tools to make the encoding. With that in mind, let’s take a quick peek at how pre-alpha x265 stacks up against the well-optimized x264. 264 in very fine detail and background clarity. Download latest release from Github. HandBrake will only handle HDR10 metadata. Mainstream support for HDR comes way of the Rec. Getting ffmpeg with libx265 support; Viewing options; Rate control modes; Passing Options; Lossless . I found by testing that FFV1 compresses vastly better (file size = ~80% of x265) at least on some kinds of video (if best settings are chosen for both codecs). HandBrake is another encoding tool available for users who like to choose the best parts of other programs. There is no point using Nvidia's HEVC encoder for low bitrate encodes: the quality is horrible in comparison to an x265 Medium encode, with reduced detail across the entirety of the frame. We accept a multitude of project assets for both HD and UltraHD video. 264/AVC)? x264 is a free software library developed by VideoLAN for encoding video streams into the H. 265 Codec: MainConcept encoding and decoding performance in amazing broadcast quality up to 8K 10-bit live. Just from the title I can say that this will need software decoding on all consumer devices. For 1080p60fps you need to use CPU encoding on mid-range AMD cards. The NVIDIA NVENC hardware encoder has a limited set of advanced encoder options. produce HDR with FFmpeg, check out the article at bit. x265 is a software codec for creating digital video streams in the High Efficiency Video Coding (HEVC/H. We recently got our hands on a pre-alpha. The pixel format is YUV 4:2:2 which is HEVC profile 2. We recently got our hands on a pre-alpha build of x265, an HEVC encoder . However, in the consumer CPU space we’ve been limited to 4-6 cores for almost a decade now. Check the capability of your installed version of x265 for 10bit encoding as follows: [email protected]~$ x265 -V -D10 x265 [info]: HEVC encoder version 2. Our DVDLogic KITe authoring suite allows us to produce reference quality, spec compliant BDCMF and UHDCMF masters for disc replication. The DV data does show up in Plex and the movies play back well with DV from the Plex app on my 2019 Nvidia Shield --> Yamaha A/V receiver --> LG C9 TV. Using x265 Prior to encoding in Staxrip, you need to extract the dynamic metadata file, using the CLI tool hdr10plus_parser by Quietvoid. They do however lack most external libraries (like lame for mp3 encoding or x265 itself for H. So it can do 4:2:2 at 10 bit depth, and even 4:4:4 at 10 bits apparently, but there's no indication of how to set the output bit depth. The two-pass encoding didn't reduce the file size as much as I expected and, in the case of x265, it increased the file size and not reduce it. This one is probably the toughest to decode, as it takes a little guesswork. I'm currently using StaxRip for HDR encoding using NVENC HEVC and it . 265/HEVC with FFmpeg for playback in QuickTime I thought I'd try re-encoding to HEVC using FFmpeg to try to save . Encoding of videos in HDR formats currently requires the use of HEVC video codec, operating in Main10 profile, and using 10-bit pixels. Note: libvpx does not have a fixed QP mode. Allowing proper and spec compliant DVD, Blu-ray, 3D Blu-ray, UltraHD/SDR and HDR disc authoring. I just received my aTV 4K, so will try how do they play from iTunes as soon as I can. Hi, There is a bug within the HDR10\\+ code of x265 that segfaults when using --dhdr10-info and a JSON containing different `NumberOfAnchors`. The standard open-source x265 implementation of HEVC in FFmpeg performed two encodings. To achieve the increased compression, the x265 encoder also requires more processing power than the x264 encoder. Legacy to the newest standards, including, but not limited. This means that a video file encoded. HEVC encoding algorithm supporting HDR(High Dynamic Range) Video . However, in the consumer CPU space we've been limited to 4-6 cores for almost a decade now. For those people who wish to encode HEVC video with NVENC, the good news for you is that the program now supports Nvidia H. 2020 color space, so you could do your own color grading to produce HDR effects, but (well, depending on your source), keeping HDR intact isn't going to happen (like for commercial blu-rays, all "rips", including ones that say they offer HDR, are using the encoder's own adjustments). Most of the 10bit HDR files I have seen seem to be smaller than their 8bits encodes for a given. VP9 vs HEVC Encoding test set sequence table JVET common test conditions and evaluation procedures for HDR/WCG video – JVET-P2011. MainConcept takes video encoding to new heights! With the MainConcept HEVC/H. First things first, you need a good cpu for 1080p x265 hdr encoding and a beast of cpu for 4k x265 hdr encoding, otherwise you'll have to . When the device you are going to watch it on doesn’t support it. 0 default) Set Bitrate to 20000 (or 30000) Recording using CPU encoding. This site contains some more detailed information about the encoding/decoding capabilities of 7th generation and newer Intel® Core™ processors. For live encoding, MulticoreWare’s UHDkit product employs multiple instantiations of x265 with tight integration to encode 4K HDR content at 60fps and optimize ABR work flows. aq-mode 1, 2, 3 (2 always fully disabled the hdr -the x265 staff should fix it, 3 worked ok) ipratio bpratio 1. Throwing more CPU cores at this problem usually provides a linear gain in the encoding speed. I believe that libx264 is now capable of doing 10-bit 4:2:2 encodings, but I can't seem to get it to work. t3, hnq, en, fl, lv, im, 30, 08, x6j, 861, zaj, rv, l6, kt, 12n, 8ft, fvo, 9d, dk, gr8, cb, 8y, gw, fo, 7h, v3c, 1mu, ak0, 28, ay4, o5, cdb, sjb, 47, 54, xh, tk, so, 3li, 1j, 377, 6mb, tr4, c1h, l9w, mey, mbh, e95, 42, uu, 0m
