H265 Settings exclusive to H.265/HEVC encoding. Here we can see x264 has a much harder time at lower bitrates. Unfortunately, the same can't be said about videos. ffmpeg -c:v libx265 -preset fast -crf 28 -tag:v hvc1 -c:a eac3 -b:a 224k -i <source> <target>. FFmpeg best settings to encode Blu-Ray. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Thank you, after working with hardware encoding for so long, would you recoment this over the CPU encoding or are the disadvantages of quality/filesize still that big? By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Does ffmpeg really use my Graphics card to encode? There aren't some commercial products based on x265 nowadays? Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? Thank you very much. However, CRF shows its true edge on the lowest 1%, easily beating out ABR at every turn. Zero-delay or sliced thread mode has no delay, but this option farther worsens multi-threads quality in supported encoders. Is there a way to only permit open-source mods for my video game to stop plagiarism or at least enforce proper attribution? Quality perception for dynamic pictures differs severely compared to static images, so hacks like this help your video appear of good quality even in case of further reducing the size of a video. It also wont be constrained to that limit if the video requires a lot more information to capture the complex scene. Okay, okay, lets back up a step and look at the bottom 1% again as well. By default, this is disabled, and it is generally not required to set a tune option. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. I manage to get a encoded video in only 5 seconds using avi, but the quality was garbage. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Well well wishing well, that is even more definitive. 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. Below, I'll outline the points of failure I've noted, Failure 1 - Unable to transcode h265 --> h264Server couldn't keep up with the transcode during significant action scenes, Remedy: Pre-transcode to h264 for direct play (see failure 3), Failure 2 - 7.1 AAC transcodes to 7.1 EAC3 - playback stops when transcoder hits the 'throttle' limit. If you like I"d be happy to test one of your .ts files to see if there is anything else that can be done to pump up your speed and quality.

By Edgewall Software My observation is confined to standalone x265 or its deployment, whether in ffmpeg or anything else. You can indicate this by, i can link the answer to the other question. So what *is* the Latin word for chocolate? But after even a basic compression it cuts down to 1MB. I did three CRF videos first, at 22, 20, and 18, then using their resulting bitrates created three ABR videos. Find centralized, trusted content and collaborate around the technologies you use most. By using CRF 15~18 vslow, Film TUNE, and 5.1+ preset on x264 you will have a hard time getting better results with x265 with default settings. I tried H.265 10 bit, H.265 12 bit, and H.264 10 bit, and they all ended up looking washed out compared to the original file. CRF affects the quality. Is lock-free synchronization always superior to synchronization using locks? It can carry video streams compressed with the VP8 or VP9 video codecs and audio streams compressed with theVorbisorOpusaudio codecs. 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. For example, the video above from Apple's new Macbook Air site uses mp4 format, but if we look deeper, it uses the H264 codec. If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. (d). And since you're on Windows, you may want to remove the shell escapes \ above as I'm writing this from a Unix box testing the command above. Generated via Python and matplotlib (Click to view larger version) Here we can see x264 has a much harder time at lower bitrates. Well, the size was the same (7,7MB, instead of the 3,8MB using the ffmpeg -i without any other option), but it was fast. Nothing to do specifically with libx265 included with ffmpeg See. What looks good today may not look so good in the future on a new display. Still a vlc bad decoding + libx265 too young? Start by understanding the encoder's options. Profiles can be set via the -profile:v option, similar to libx264. If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? Frameworks compete by optimizing network requests, images, and code to achieve a blazing-fast loading experience. The open-source game engine youve been waiting for: Godot (Ep. Easily beating out the lowest 1% of even CRF 16 medium, two entire steps away. Add it next to your -c:v h264_nvenc -c:a ac3 You should also be able to push 2 sessions. This is a simple easy guide on how to make the best DVD conversions to H.265 encodes with the smallest file size in Handbrake without having to know or under. PTIJ Should we be afraid of Artificial Intelligence? Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. . What are the optimal settings to transcode with for Chromecast for Direct Play? Launching the CI/CD and R Collectives and community editing features for Best Web Video Encoding Practices for IOS (FFMpeg), Unable to transcode video using ffmpeg transcoder, ffmpeg command for faster encoding at a decent bitrate with smaller file size. It is faster by two orders of magnitude than libx265, but has some drawbacks. Also that I always recommend crf over hard bitrate/filesize because it is really source dependent for saving the proper amount of quality. Now this is an apples to oranges comparison. Has Microsoft lowered its Windows 11 eligibility criteria? What are the optimal settings to transcode with for Chromecast for Direct Play? How to handle multi-collinearity when all the variables are highly correlated? For everyone else, you can follow instruction on the site. I will make a few tests with h264. Your mileage will definitely vary, based on your source content, filter chains in use, specific pltform configuration variables (such as your GPU and driver versions), etc. Is something's right to be free more important than the best interest for its own species according to deontology? 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. When the device you are going to watch it on doesnt support it. Then I ran multiple two pass ABR runs using ffmpeg for both x264 and x265 using the same target bitrate. On my computer (a fairly good laptop) it usually takes half the video playtime to convert into a mp4 using a generic ffmpeg command that i simple copy and paste from stackoverflow. -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. We get closer to more codec-specific options and before that, lets learn how to strictly tell ffmpeg which codec to use instead of auto settings. The CRF scales for x264 and x265 do not correspond. is it worth to spend more time to encode slower preset? I have always read to use Constant Rate Factor over Average BitRate for stored video files (and especially over Constant Quality). thank you, I'll try it now and feedback you later ^^, I use it to decrease scale. 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. Making statements based on opinion; back them up with references or personal experience. Connect and share knowledge within a single location that is structured and easy to search. Similar to x264, the x265 encoder has multiple rate control algorithms, including: In this guide we are going to focus on CRF and Two-Pass encoding, as 1-pass target bitrate encoding is not recommended. However, Im really only dealing with 1080p rips Curious if you have any data on the difference between Medium and Slow settings at 1080p? I mainly use Handbrake now use ffmpeg because I learned Handbrake only has a 8-bit internal pipeline. Quality degradation is more prominent with higher thread counts in constant bitrate modes and near-constant bitrate mode called VBV (video buffer verifier), due to increased encode delay. TLDR: FFMPEG transcode 1080p h265/HEVC 7.1 5Mbps--> h264 12Mbps (31.6Mbps required as per PMS via Tautulli) overloads Chromecast v2, possibly due to excess bandwidth. CRF works just like in x264, so choose the highest value that provides an acceptable quality. Setting up NVENC (for Streaming) Modern OBS Studio has two ways to achieve the expected quality: the built-in NVENC H.264 (new) and the addition from StreamFX called NVIDIA NVENC H.264/AVC (via FFmpeg). 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. You can also download a static build, all of which bundle libx265. Jordan's line about intimate parties in The Great Gatsby? Viewing options (e). If we run the command above, it compresses the video down to 542 KB. When comparing to standard 4.1 profile than yes, x265 outperform it in almost any metric. It only takes a minute to sign up. Open a 2nd command line and encode another .ts at the same time. So using veryslow is more wise. 28 and 23 are the default CRF values of x265 and x264 respectively, hence the supposed equivalence. In this case, you are using two different encoders, so you get different bitrates. 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). Asking for help, clarification, or responding to other answers. The mode works exactly the same as in x264, except that maximum value is always 51, even with 10-bit support, so please read the H.264 guide for more info. 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. The number of distinct words in a sentence, Torsion-free virtually free-by-cyclic groups. (c). Connect and share knowledge within a single location that is structured and easy to search. Does With(NoLock) help with query performance? FFmpeg: For NVENC, what is a concurrent surface? rev2023.3.1.43269. So lets take a step back and look at the lowest 1% of the frames. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. FFmpeg supports hardware accelerated decoding and encoding via the hwaccel cuda, h264_cuvid, hevc_cuvid and h264_nvenc, hevc_nvenc modules. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? Is Koestler's The Sleepwalkers still well regarded? The jump from medium to slow is very significant in multiple ways. If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. For the llhp and llhq presets, as well as other presets in use, you can also override the in-built rate-control methods by passing the -rc:v arguments as exposed by the encoder options. Use CRF 23+ for videos in 4K. For example, with constant bit-rate encoding, you can specify -rc:v cbr (which is significantly faster than the cbr_ld_hq rate control method, bringing an additional ~20% boost to throughput). This means that the video should play back smoother during action scenes, but the video will take an extra 3 seconds in the beginning to start playing the movie as the buffer loads up. If the same information really answers both questions, then one question (usually the newer one) should be closed as a duplicate of the other. Privacy Policy. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. When you omit this option, ffmpeg uses -crf 32 for VP9 by . The difference between the input and the output is practically non-visible for 1080p videos. explicitly disabled interlaced encoding on Turing, github.com/SK-Hardwired/nv_hevc_hdr_patcher, The open-source game engine youve been waiting for: Godot (Ep. Then, using that information, proceed to the next step. Not bad, but we can do better! How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? shouldnt slower preset produce better picture quality? Press J to jump to the feed. Choose a CRF. The slow preset was used as it was determined to be an ideal choice in previous tests. Dealing with hard questions during a software developer interview. For instance, with NVENC, we cannot insert HDR information directly and have to use an external tool for that.

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: 3 seconds at the start is nothing as long as the movie plays fine. You can raise the output quality by specifying proper bitrates (through the -b:v,-maxrate:v and -bufsize:v settings), enabling adaptive quantization encoding techniques (spatial and temporal AQ methods are supported, of which only one can be used at a time) and by optionally (and separately) enabling weighted prediction (which will disable B-frame support) as shown below, as well as an optional filter for a proper downscale and resize if so needed. I didn't mention audio, because I just want to keep the original anyway, as there's no significant size saving potential. It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. 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. For some videos, you can try using the low resolution option, but on retina screens, it could lead to a blurry picture. 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? 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. Adapt as necessary to your encoding requirements. And one last thing is -tag:v hvc1 that makes video work on iOS and macOS devices. https://gist.github.com/cdgriffith/20c8bbb220a05358da47710e2a512308 is the script I wrote to be able to compare a lot of different presents to a single source. Thanks for contributing an answer to Stack Overflow! There is no such thing as "proper bitrate". But when I looked at the videos I was enjoying just fine at CRF 22, they were mostly coming out with less than a 10Mbps bitrate. As with x264, you need to make several choices: This example uses AAC audio at 128 kBit/s. Edit: learned more about buffer size and found out that the buffer should be substantially larger (recommended 2x the bitrate). To some, including myself, it could be worth the extra 4000kbps jump from CRF 22 to CRF 20. I tried to a post a total comment but got a mess. Keep in mind that is while still being lesser quality than CRF 18 - Slow. Video Production Stack Exchange is a question and answer site for engineers, producers, editors, and enthusiasts spanning the fields of video, and media creation. However, there is still a solution. I tried to look up the documentation, but i simple don't have the multimedia background to understand it. Theoretically Correct vs Practical Notation. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Note that depending on the filter in use here, a hardware-based decoder (as described in section (c) will introduce constraints that your filter must be able to handle, or else your encode will fail. 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. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? The original was H.265 encoded with a .ts extension. Was Galileo expecting to see so many stars? If it has HDR10 data and trying from the command line, also will need to provide --master-display copy --max-cll copy to VCEEncC (auto added in FastFlix as well). What tool to use for the online analogue of "writing lecture notes on a blackboard"? Handbrake 1.2.2. Also, I raised a flag to mark it as duplicate. The short answer to the deviation from expected performance is that x265 is still under "heavy development". RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? Even though it does cost double the time of medium it really delivers in the quality department. While its narrow versatility makes it incredibly frustrating to work with, there's never been another video player in history that scrubs as well, or uses laptop CPU/battery as efficiently. Through some experimentation I found that I personally never can really see a difference between anything lower than 22 using a Slow present. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Keep in mind that fine-tuning any of the options is generally not necessary, unless you absolutely know what you need to change. rev2023.3.1.43269. Your inputs are already H.265/HEVC, so you can simply mux them into MP4 without needing to re-encode. 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. On current builds (as of 2021+), note that presets are further customizable with tunables based on the use case, via the -tune:v parameter, as documented here. 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. For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. Few more options are applicable to ffmpeg no matter whether you use H265 or VP9: -an - removes audio track. However most devices finally have some native h.265 decoding. But the quality is not as good as expected. That said, you can try to establish your own calibration between the current versions of the encoding libraries in your ffmpeg by running the following command, which executes two popular video quality metrics: The final lines of the console output will contain: So, run the command once with the x264 output and once with x265 and compare with different x265 outputs, till you get similar measures. You didn't mention audio, but consider using stream copy mode (-c:a copy), or if you want to re-encode it then Opus (-c:a libopus) is hard to beat assuming the format doesn't really matter to you. When you omit this option, ffmpeg uses -crf 32 for VP9 by default. x265 CRF 28 is supposed to be equivalent to x264 CRF 23. (I am thinking 20-30), As I'm new to this, I tried doing some research and found that mostly it's about choosing the correct CRF and preset. Yes, @Dr.Snail. At both CRF 24 and CRF 22, even the lowest frames dont dip below SSIM 0.95. 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. 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. Video optimization for the web with ffmpeg in simple scenarios is pretty straightforward and requires just two commands to run: Adjusting -crf values could help to find the best suitable option with a minimal size. Not sure if theyre agnostic of resolution. Even if your source video doesnt use the HDR color space, it compresses better. Ackermann Function without Recursion or Stack. Using ffmpeg for streaming video composition from Python : why the sound is cut only when streaming into a mp4 file ? How to increase the number of CPUs in my computer? You can verify lossless encoding by looking for x265 [info]: lossless compression ratio in the console output from your encoding command, or refer to the hash demuxer for verification. Launching the CI/CD and R Collectives and community editing features for Java library for converting MP4 to MPEG-2 TS in memory? You can use ffmpeg as a beginner just by running: The output will be WebM encoded with VP9 with a pretty decent compression out of the box. First things first, this is NOT a guide for Dolby Vision or HDR10. What is interesting, is if we put CRF 16 - Medium encodings bitrate on this chart it would go shoot off the top at a staggering 15510kbps! A more up-to-date write-up with the current options for newer and older builds can be found here. First thing I did was to chop out a minute segment and promptly remove the HDR. Is something's right to be free more important than the best interest for its own species according to deontology? It means there is less differences between the original and the compressed one. Is something's right to be free more important than the best interest for its own species according to deontology? I know from some small scale testing that the gaps between the different presents will remain similar (newer article has better graph for that). Code Calamity 2023. For H265, we need to learn some more extra options. How can the mass of an unstable composite particle become complex? 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). Does Cosmic Background radiation transmit heat? Ive specified it to 3x the 8Mbps (so 21M). When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. On the section of video I chose, x264 needed considerably more bitrate to achieve the same score. Server: MacBook Pro with 2.66GHz i7, 4GB DDR3Connection to router: 5GHz WiFiMonitored with Tautulli (PlexPy), Chromecast v2 --> Onkyo Receiver 7.1 setup --> 1080p Sony Projector, Chromecast v1 --> Yamaha Receiver 5.1 setup --> 1080p TV, Amazon Firestick --> Yamaha Receiver 5.1 setup --> 1080p TV, These are connected over 2.4 GHz, unfortunately, (I know, I'm running some seriously old components in heresome are a decade old. If you wish to master the tool, you will have to learn how to use flags. On the adaptive quantization implementation in NVENC: Note that Temporal AQ will redistribute bits in time, so a more complex frame will receive more information. Id love to learn from you and be able to follow along and further understand all this. I personally think the extra 2500kbps for the large jump in minimum quality from CRF 24 to CRF 22 is a must. Even thought the file size was much larger for the CRF 16 Medium encoding than it was than for the CRF 18 Slow! We haven't used it in VP9 WebM because its architecture does not require this and always guarantees progressive loading. Choose a tune (optional). Predictable file sizes are a priority. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. 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. 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. I liked the second command a lot because it was relative fast (4 and half seconds) and was really small. 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. Is lock-free synchronization always superior to synchronization using locks? Thanks @szatmary. rev2023.3.1.43269. Error:-[libx264 @ 000001fa2ffdd080] height not divisible by 2 (244x207), Integral with cosine in the denominator and undefined boundaries. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? Connect and share knowledge within a single location that is structured and easy to search. You can remove this scale=858:482: from my scripts. Getting ffmpeg with libx265 support ffmpeg needs to be built with the --enable-gpl --enable-libx265 configuration flags and requires x265 to be installed on your system. See this detailed answer: How to set proper bitrate for ffmpeg with hevc_nvenc? The scale option can preserve the aspect ratio of the original video by accepting the width and extra parameter with possible values of -1, -2, or -n. -2 value guarantees that the resulted output resolution will be even. If you require interlaced encoding support, please switch to Pascal or older SKUs instead. What are some tools or methods I can purchase to trace a water leak? The CRF videos were done via Handbrake using x265 10-bit, whereas everything else was done via ffmpeg using x265 or x264 8-bit. My experience with using nvenc is that you need to tell it what bitrate you want -- it defaults to VBR, which is fine, but no amount of tuning makes up for the fact that it always wants to give you a 2M average bitrate no matter what resolution file you feed it. 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 ?

If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? ffmpeg creates large compressed files for tiny videos? (f). So lets take a step back and look at the lowest 1% of the frames. Anything from 18-40 could give a very decent quality level. TLDR: FFMPEG transcode 1080p h265/HEVC 7.1 5Mbps--> h264 12Mbps (31.6Mbps required as per PMS via Tautulli) overloads Chromecast v2, possibly due to excess bandwidth. What are examples of software that may be seriously affected by a time jump? Help with ffmpeg settings H265. In this test, I encoded all videos with ffmpeg using the default presents.
