There's a TLDR at the end. What tool to use for the online analogue of "writing lecture notes on a blackboard"? Why did the Soviets not shoot down US spy satellites during the Cold War? By Edgewall Software Use the -g 1 option for FFmpeg 4.3 and newer or if you're using a build from the git master branch. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? Thanks @szatmary. Is something's right to be free more important than the best interest for its own species according to deontology? . Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? If you are encoding to x264 or x265, encode to 10-bit if your devices support it. I wanted to thank you for all this great work youve done on these articles. Profile ( -profile) The profile determines which features of the codec are available and enabled, while also affecting other restrictions. Consider your encoding workflow and adjust as necessary. thank you, I'll try it now and feedback you later ^^, I use it to decrease scale. What looks good today may not look so good in the future on a new display. Also h264 is faster to encode that h265, but again it will impact quality. In this case, you are using two different encoders, so you get different bitrates. At both CRF 24 and CRF 22, even the lowest frames dont dip below SSIM 0.95. and also why slower and veryslow SSIM is lower than slow preset? Their overall average SSIM scores were near as identical. - Code Calamity, Animated AVIF is finally coming to Firefox, AMD improves video encoding yet again! how to use FFMPEG to transcode h264 to h265 on Ubuntu 12.04? For better visualization, I am going to show you how applying different options to ffmpeg decreases the file size and changes the quality. To make your file compatible with Apple "industry standard" H.265 you have to add the following argument -tag:v hvc1. Predictable file sizes are a priority. It is not a royalty-free codec - perhaps, that is why the adoption rate is much less than of WebM's. Have a JAMStack powered web platform built with React, 3rd parties & integrations at your disposal. Then in three years H.266 / VVC toolsets will probably be popping up. I've gone through this sub and tried to improve my transcodes, but I'm still not 100% there. Best settings for converting from h264 to hevc? A few interesting options for us are: libvpx-vp9 - which is used be default when you convert to WebM using VP9 codec, libx265 - for H265 code and mp4 container, hevc_videotoolbox - for H265 with a hardware acceleration. It is less efficient in terms of optimization and does not have Constant Quality mode (-crf) and presets we used in the previous example. So lets get a little more apples to apples. Let's take a look at what's needed to set up your stream for massively improved quality. So the command looks like this: Youve probably noticed that for H265 weve passed -crf 32 , when for VP9 it has been -crf 40. Providing tools to analyse, process, transcode, and deliver images and videos, on the shoulders of state-of-the-art cloud, media and AI technology. Acceleration without force in rotational motion? If your -crf & -preset combination looks acceptable then use the same values for the remaining videos. Afterwards compared them to the original using the Structural Similarity Index (SSIM). Does With(NoLock) help with query performance? Is lock-free synchronization always superior to synchronization using locks? Transcoding FLV toMP4 with ffmpeg very slow, FFMPEG resize video not working in browser or IOS. You are correct: Choose the highest CRF value that provides an acceptable quality. Does Cosmic Background radiation transmit heat? ffmpeg is a CLI tool and it has a lot of options that is nice to know. Yes, @Dr.Snail. H265, a.k.a HEVC (High-Efficiency Video Coding), is a codec supported by Apple and shows the same 20-50% better efficiency than its H264 older brother. Thus comparing the two encoders via their default 8-bit compressors.I found this code to convert the 10-bit HDR yuv420p10le colorspace down to the standard yuv420p 8-bit colorspace from the colourspace blog so props to them for having a handy guide just for this. To learn more, see our tips on writing great answers. . My first step is to convert images into yuv format: ffmpeg -f image2 -i "C:\DATA FOLDER\images%d.png" video.yuv And I try to convert it as a .mkv file, losslessly: If I change the playback to 8Mbps (forcing the PMS to transcode rather than direct play), the Chromecast can handle it. Encode new files to MP4 or MKV. Why does Jesus turn to the Father to forgive in Luke 23:34? Why are non-Western countries siding with China in the UN? Is a wanted design with a bigger amount of CRF values or could be considered this way because libx265 is still not mature enough in ffmpeg? If you look at the PDF I linked in the last comment, there are many encoders out there - most proprietary. You can change this by adding -b:v option to ffmpeg. For everyone else, you can follow instruction on the site. Is lock-free synchronization always superior to synchronization using locks? I have a raw footage and the quality of details of h264 with same CRF setting looks better than h265. is it worth to spend more time to encode slower preset? Handbrake has a GUI, and it makes it much easier to use; however, using ffmpeg is a more flexible option in case you want to render videos with alpha(transparent) channels or use hardware acceleration that speeds up compression a lot. Suspicious referee report, are "suggested citations" from a paper mill? It enables constant quality mode, which guarantees a certain perceptual quality level within the entire video by passing a number from 0-63 (VP9) and 0-51 (H265), where 0 is the best quality and the maximum number is the worst. When comparing to standard 4.1 profile than yes, x265 outperform it in almost any metric. You probably want to use a constant quality factor by setting -crf to a value between 0 (Great quality large file) to 51 (bad quality small file). Antn Garcia.

FFmpeg commands I using are the following: ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv and But based on just the average, slow was the obvious choice, as even bumping up the CRF from 18 to 16 didnt match the quality. The results were surprising to me to be honest, I was expecting medium to have a better margin between fast and slow. Between H.264 and H.265, from what I've read the difference is about 30%, which is an impressive improvement at that point, considering how efficient H.264 already was, but from a practical standpoint it's too small to justify a systematic conversion just for the sake of saving a few gigabytes (or even hundreds of gigabytes - you may end up Hey Jamie, sure thing! Modern video codecs can deliver excellent quality while preserving a very reasonable size. Would the reflected sun's radiation melt ice in LEO? First thing I did was to chop out a minute segment and promptly remove the HDR. We have some hard date, lets use it. What are some tools or methods I can purchase to trace a water leak? Thanks for contributing an answer to Stack Overflow! I got 700fps (Yours settings) on a GTX750 (non TI) (the cheaper one), I got 925fps (Your settings with ac3 audio), Answered here: 18 slow 68.298806 0.96016 Also that I always recommend crf over hard bitrate/filesize because it is really source dependent for saving the proper amount of quality. Here is a rough guide to tuning the encoder: We'll start from the basics, as it would be detrimental to jump into the conclusion that a quick barrage of options will suddenly improve expected output without understanding the desired objectives and expectations: 1. Making statements based on opinion; back them up with references or personal experience. Theoretically Correct vs Practical Notation. ffmpeg: Output mpegts with a single program containing 1 audio and 3 video, Set keyframe interval in ffmpeg when using nvenc. See FFmpeg Wiki: H.265 for more info. How to make PNG video render into 10bit h.264 matroska/avi file? The absolute path to the output file. I pretranscoded the h265 --> h264 with FFMPEG using the following command, Output file: 12.1 Mbps 1080p h264 7.1 AAC mkv. Connect and share knowledge within a single location that is structured and easy to search. Video Production Stack Exchange is a question and answer site for engineers, producers, editors, and enthusiasts spanning the fields of video, and media creation. I started with a 4K HDR example video. Since bitrate = file size / duration: You can also forgo the bitrate calculation if you already know what final (average) bitrate you need. Keep in mind Im talking exclusively of x264 level 5.1+. I know from some small scale testing that the gaps between the different presents will remain similar (newer article has better graph for that). libvpx-vp9 has the option -deadline which accepts following values: Time to switch to H265 and libx265. Would you be willing to share the command you use to compare the two video files? For two-pass, you need to run ffmpeg twice, with almost the same settings, except for: For libx265, the -pass option (that you would use for libx264) is not applicable. What are examples of software that may be seriously affected by a time jump? I see, so because of this heavy development status even if I decide to move from ffmpeg and libx265 to another encoder the results will not change so much right? Now this is an apples to oranges comparison. I will make a few tests with h264. Well well wishing well, that is even more definitive. Just curious. Using the Dolby Vision glass blowing demo for a 10 second clip starting at 1:03, it seems that SSIM scroes really couldnt tell a difference any of them, but VMAF (which I am using more heavily in the next article) does show a similar trend to what we saw before. Strange that the video playback stops if the transcoder gets too far ahead, reaching its buffer limit, on the audio track only? What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? Currently focused on React, Next.js, Gatsby. Keep in mind that fine-tuning any of the options is generally not necessary, unless you absolutely know what you need to change. As an alternative to -crf its possible to use -b:v, which allows manually defining the bitrate of the video(read more). You can list private options available in this encoder with ffmpeg -h encoder=libx265. Not bad, but we can do better! I want a setting that I can use on any incoming 4K HDR video I buy. 18 medium 67.552191 0.960256, 20 slow 67.835845 0.959723 To subscribe to this RSS feed, copy and paste this URL into your RSS reader.

Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. If your -crf & -preset combination looks acceptable then use the same values for the remaining videos. In the past, I went straight to Handbrakes documentation. The Main profile is capable of 8-bit, Main 10-bit is capable of 10-bit, and Range Extended is capable of more than 10-bit. Thank you, I did look at the wiki (the H.264 page as well, which is more elaborate), I just wanted to make sure I'm not missing anything else that would be worth paying attention to. So, by clever combination of webm + VP9 and mp4 + H265 for our videos, we can achieve 94% global coverage. Still a vlc bad decoding + libx265 too young? CEO at Pixel Point and software engineer with 10+ years of web development experience. I hope you found this information as useful as I did, if you have any thoughts or feedback please let me know! As a bonus you can use the following nice shell script below that can create for you optimized video in VP9 and H265 with a single command. Powered by Trac 1.4.2 as in example? When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. Famous codecs are H264, H265, and VP8/9. Not sure if theyre agnostic of resolution. What is the potential range for a good CRF value? (And if I ran these tests first, I would have even used slow for all the other testing!). Something wrong with reddit clipboard. shouldnt slower preset produce better picture quality? (f). 1. So lets take a step back and look at the lowest 1% of the frames. Introducing FastFlix AV1 encoder GUI and more! I tried encoding some 4K HDR files using Handbrake and they look washed out. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. -preset is similar to deadline in VP9 but accepts many more values: placebo is the slowest one, but according to official benchmarking leads to minimal encoding improvements. Convert ffmpeg encoding from libx264 to h264_nvenc. Higher presets (such as the default medium) have rapidly diminishing returns in quality output while at the same time incurring significant slowdowns in encoder throughput. Some popular examples of video formats are mp4, WebM, or MKV. Connect and share knowledge within a single location that is structured and easy to search. Theoretically Correct vs Practical Notation. Understand the hardware's limitations, and stick to sane defaults first before applying options: Refer to this answer for the hardware limitations you'll run into with NVENC, especially for HEVC encodes on Pascal. I used a three minute 4K HDR clip, using Handbrake to only modify which present was used. rev2023.3.1.43269. A minute of 1080p video takes up ~150MB of storage, and double that for 60fps mode or 4K. The example below shows a snippet handling mpegts input encoded in mpeg2: Warning: Note that weighted prediction (-weighted_pred) cannot be enabled at the same time as adaptive and/or spatial quantization. That way I know I should never be disappointed. Does Cosmic Background radiation transmit heat? https://i0.wp.com/codecalamity.com/wp-content/uploads/2019/04/4K_preset_avg_extra.png?ssl=1 why there is CRF 16 and CRF 17 dot showing? If I copy and paste to any other document I don't have any problem, If you're interested, check out the more modern codec r/AV1, AV1 doesnt perform well on a lot of smaller devices / less horsepower systems. Really awesome! If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. It means there is less differences between the original and the compressed one. Help with ffmpeg settings H265. Because if every frame was that good, we shouldn't need more than 6Mbps x265 or 10Mbps x264 4K video. To learn more, see our tips on writing great answers. Great explanation. The bitrates are as expected, the higher quality it gets the more bitrate it will need. RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? The command I use boils down to ffmpeg.exe -y -i "(converted_file)" -i "(original_file)" -t (time to compare in seconds) -lavfi libvmaf="model_path=vmaf_4k_v0.6.1.pkl:log_path=details.txt;[0:v][1:v]ssim=1" -report -f null -\n. Most time effective web format for converting h.265, The open-source game engine youve been waiting for: Godot (Ep. At very low bitrates, however, x265 will indeed surpass x264, but at the levels of quality it does with default settings, you will be smudging a lot of fine grain and dark detail and the source would benefit from downscale DNR and pre-processing anyway. It only takes a minute to sign up. Bulk compress videos to H.265 (x265) with ffmpeg Published on 2020-04-21 python automation Despite being a relatively modern phone, my OnePlus 6T records video using the H.264 codec rather than the newer H.265 HEVC codec. This is best explained with an example. The CRF scales for x264 and x265 do not correspond. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA.

If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? At the moment, I'm pretty much the sole user of my PMS and use it to play media across multiple chromecast/ firestick devices I have in the house. Think of video format as a container that defines file structure for carrying video and audio streams. Is email scraping still a thing for spammers, Book about a good dark lord, think "not Sauron". This time with Pre-Analysis. If you require interlaced encoding support, please switch to Pascal or older SKUs instead. Is there a more recent similar source? Does ffmpeg really use my Graphics card to encode? How to increase the number of CPUs in my computer? Default psycho-acoustics tunings on x264 are much more mature and balanced for perceived quality than x265. In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. You will have to tweak A LOT of the extra complex settings of x265 encoder to even MATCH x264, let alone surpass it in size to perceivable quality, and by the time you do, you will see that x265 is just a order of magnitude slower than x264 to achieve marginally better results which is very problematic with 4k encodes. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Aka a old movie with lots of film grain will need a lot higher bitrate than a modern action / adventure move, which will itself needs a lot higher than an animation. So, if generally the CRF of h265 are "better" qualitatively speaking than the x264 ones how is possible that the encode results of x265 is worst than x264 with same CRF ? I use the monochrome12 profile. Maybe something more visible at lower bitrates? ffmpeg -i input.ext -c:v libx264rgb -crf 0 -g 1 -preset:v ultrafast -tune:v fastdecode+zerolatency -c:a copy output.mkv Intra will be faster for decoding and seeks, x264 will be faster than x265 A lot of it depends on your hardware, and personal tolerance for speed If it's still too "slow" for you - you can try the proxy edit feature This guide focuses on the encoder libx265 which can offer around 2550% bitrate savings compared to H.264 video encoded with libx264, while retaining the same visual quality. Now I know that x265 can be around 50% more efficient than x264, and that YouTube needs it higher quality coming in so when they re-compress it it will still look good. Can I use a vintage derailleur adapter claw on a modern derailleur. If you want a single go to setting for encoding, based on my personal testing CRF 20 with Slow preset looks amazing (but may take too long if you are using older hardware).

Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? PTIJ Should we be afraid of Artificial Intelligence? *** CRF 20-23 for most 1080p videos is enough. To know more about this, check out a wonderful demohere. (Well get to that later.). This information alone confirmed for me that I will only be using x265 or newer encodings (maybe AV1 in 2020) for storing videos going forward. For H265, we need to learn some more extra options. Do you think for H.265 but with 1080p and less content that all of what youve posted here would still be applicable or do you think its only for 4k content? CRF affects the quality. Do people usually encode with 20+ for 1080p? To learn more, see our tips on writing great answers. Does With(NoLock) help with query performance?

I'm using my FFMPEG with the suport of my GPU (NVENC) to convert files from my satelite receiver (SD, mpeg2 .TS-Files) into h264 .mp4-files. Learn more about Stack Overflow the company, and our products. ffmpeg -i data2.mp4 -c:v libx265 -c:a copy d2.mp4 However when I use the hevc_nvenc, I get a very high bitrate (about 2M), I need to have a bitrate as low as possible and keeping almost the same quality. How can the mass of an unstable composite particle become complex? For streams, use the URL and if needed, prepend extra flags (such as buffer sizes) as needed. Constant Rate Factor over Average BitRate, Discover AWS State Machines using Python Lambdas for an ETL process. Then I ran multiple two pass ABR runs using ffmpeg for both x264 and x265 using the same target bitrate. Thankfully there is a simple answer. Call up the binary. The one advantage of hevc_videotoolbox over libx265 is that it supports encoding videos in H265 with alpha channel. But after even a basic compression it cuts down to 1MB. The webm was quite small, but take many times the amount of time that mp4 took.

Still, we get a good idea of where these show up. Linking VCEEncC in the Settings panel of FastFlix is the easiest way to get started with it and will automatically put the required setting of --output-depth 10 to make it 10 bit. The normal wisdom is to use the the slowest you can stand for the encoding time. It only takes a minute to sign up. I have only recently discovered FFmpeg and tried using the x265 video codec to reduce the video stream size for some videos, and realized that I can achieve tremendous space savings, especially for video recorded via smarthphones. compression.ru/video/codec_comparison/hevc_2015/. If you wish to master the tool, you will have to learn how to use flags. Asking for help, clarification, or responding to other answers. If the source has HDR and I want to preserve it, it should be in 10-bit H.265. This is why the duplicate flag has been declined. Libvorbis for audio seems slow. Also note that the highest marker on this chart is 0.98, compared the total average charts 0.995. Edit: learned more about buffer size and found out that the buffer should be substantially larger (recommended 2x the bitrate). It states that for 4K videos with x265 they suggest a Constant Rate Factor (CRF) encoding in the range of 22-28 (the larger the number the lower the quality). Viewing options Pretty new to this but I have one questions I cant seem to read up on, If I have a 10 bit 4k movie and I use the H265 AMD VCE video encoder, would I lose the 10 bit with the new conversion? Super User is a question and answer site for computer enthusiasts and power users. What's the difference between a power rail and a signal line? nodejs ffmpeg play video at specific time and stream it to client, ffmpeg mp4 video cannot be played in old tv, Duress at instant speed in response to Counterspell. Now that it is clear, the next important thing to learn is that not every codec is suitable for every video format. Even though it does cost double the time of medium it really delivers in the quality department. Code Calamity 2023. Choose the highest CRF value that provides an acceptable quality. Easiest way to remove 3/16" drive rivets from a lower screen door hinge? It looks to take about a crf increase of 2 to achieve near parity of medium to slow (aka 18 medium is close to 20 slow). Reddit and its partners use cookies and similar technologies to provide you with a better experience. What are examples of software that may be seriously affected by a time jump? Could the loss of quality be caused by VLC and its experimental support in deconding h265? Maybe my setup isn't the best: I'm using ffmpeg for transcoding and vlc for review the videos, then i copy the screen content and compare the screens on a program like photoshop. It works if I specify the output bitrate, but I want to know how to figure out the proper bitrate? ***### Encode video as x265 HEVC 10bit.ffmpeg -i "input.mkv" -pix_fmt yuv420p10le -c:v libx265 -preset slow -crf 28 -c:a copy -x265-params profile=main10 "output".mkv### Same as above, but as a two-pass x265 HEVC 10bit encode.ffmpeg -y -i "input".mkv -c:v libx265 -b:v 1500k -x265-params pass=1 -an -f null /dev/null && \ffmpeg -i "input".mkv -c:v libx265 -b:v 1500k -x265-params pass=2 -c:a copy "output".mkv. I did three CRF videos first, at 22, 20, and 18, then using their resulting bitrates created three ABR videos. And one last thing is -tag:v hvc1 that makes video work on iOS and macOS devices. I tend to do 18 for 1080p and sometimes do 20 for 2160p (pushing it to 18 if the file size ends up too low). (As a heads up h.265 is the specification, and x265 is encoder for it. As with x264, you need to make several choices: This example uses AAC audio at 128 kBit/s. This uses the native FFmpeg AAC encoder, but under AAC you will find info about more options. (g). Even if there is no sound in a file, there could be empty audio track information that will occupy some additional weight, so always use it for muted videos. Both values result in a very similar bitrate for both videos, just a syntax difference due to different accepted number range. Please do not post the same answer to multiple questions. So using veryslow is more wise. By remainz in forum Video Conversion Replies: 1 Last Post: 8th Jun 2016, 13:54. Thanks for contributing an answer to Super User! I'm doing some experiments with HEVC x265. Over 8 Mbps for most 1080p content with x265 is plenty good so you definitely don't need to use the slowest encoding settings. Those other encoders might be better - I haven't studied that PDF closely. Attempting to do so will result in encoder initialization failure. See FFmpeg Wiki: H.264 for more info. rev2023.3.1.43269. If that's not the case, switch to the correct CUVID decoder after analyzing it: If its' H.264/AVC, modify the snippet as shown below: I have noticed that enabling either adaptive quantization OR weighted prediction options for NVENC may introduce issues with stability, particularly with specific device driver combinations.
