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 this, you can use -c:v flag. It makes your video web-optimized and results in faster video readiness. I use the monochrome12 profile. Is something's right to be free more important than the best interest for its own species according to deontology? 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. 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. There is only one time to not use it. FFmpeg commands I using are the following: I used 30 as CRF for testing purposes because the artifacts are more visible :). You're still doing high bitrate encoding. 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 understand all of the settings. Ive specified it to 3x the 8Mbps (so 21M). The default is 28, and it should visually correspond to libx264 video at CRF 23, but result in about half the file size. What does a search warrant actually look like? As an alternative to -crf its possible to use -b:v, which allows manually defining the bitrate of the video(read more). (This will generate a logfile that ffmpeg needs for the second pass. Still, we get a good idea of where these show up. 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. 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). Zero-delay or sliced thread mode has no delay, but this option farther worsens multi-threads quality in supported encoders. 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). Even though others have tackled this issue, I wanted to use the same material I was already testing and make sure it held true with 4K HDR video. Introducing FastFlix AV1 encoder GUI and more! In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. As always, start by specifying a preset. I guess this solves my problem. You can speed up and slow down encoding ruins presets. Jordan's line about intimate parties in The Great Gatsby? Pythons New Structural Pattern Matching! 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. If the source has HDR and I want to preserve it, it should be in 10-bit H.265. It is well known between pros that SSIM and PSNR are not good measures or SUBJECTIVELY PERCEIVABLE quality. Generated via Python and matplotlib (Click to view larger version) Here we can see x264 has a much harder time at lower bitrates. shouldnt slower preset produce better picture quality? Their overall average SSIM scores were near as identical. Powered by Trac 1.4.2 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). But after even a basic compression it cuts down to 1MB. Strange that the video playback stops if the transcoder gets too far ahead, reaching its buffer limit, on the audio track only? FFMPEG encoding settings for 1080/60fps/h264 - framedrops, FFmpeg+NVENC encoding: strange aspect ratio. The best answers are voted up and rise to the top, Not the answer you're looking for? What would be the most time effective format and how to convert a raw h.265 video to it? rev2023.3.1.43269. https://www.youtube.com/watch?v=bzgFL-gNF9g. 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? Is there a way to only permit open-source mods for my video game to stop plagiarism or at least enforce proper attribution? RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? Use CRF 23+ for videos in 4K. I mean there are many improvements that have been made in NVENC and NVENC HQ should be equal quality compared to default x264. So using veryslow is more wise. Why using b-frames does not reduce the size of my video (using ffmpeg and nvenc)? Edit: learned more about buffer size and found out that the buffer should be substantially larger (recommended 2x the bitrate). 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. This is a good starting point on why these values matter. The only point of using x265 is for compatibility, lossless and HDR content, otherwise, even at SDR 4k x264 will fare better if given enough bitrate. Attempting to do so will result in encoder initialization failure. FFmpeg best settings to encode Blu-Ray. If you wanted to target 4 Mbps you'd want to be using veryslow for sure. The SSIM result is done frame by frame, so we have to average them all together to see which is best overall. See FFmpeg Wiki: H.265 for more info. At this point, it would be imperative to mention that decoders have specific constraints, such as expected input resolutions, supported codecs, etc, and as such, it's recommended that in production, to determine and validate the need for hardware-accelerated decoders as failure at this stage results in a failed encode and is unrecoverable. Now, if I have a super computer and unlimited storage, I might lean towards CRF 18 or maybe even 16, but still wouldnt feel the need to take it the whole way to CRF 14 and veryslow or anything crazy. It is not a royalty-free codec - perhaps, that is why the adoption rate is much less than of WebM's. If we wanted to go by YouTubes recommendations for a video file that will be re-encoded again, you would only need a 25Mbps x265 file instead of a 35Mbps x264 video. Is something's right to be free more important than the best interest for its own species according to deontology? Slower = better video quality and compression. Making statements based on opinion; back them up with references or personal experience. 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. What looks good today may not look so good in the future on a new display. Thanks for contributing an answer to Super User! The slow preset was used as it was determined to be an ideal choice in previous tests. See a list of available x265 profiles. 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! 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. Is this the best possible solution, or is there a better way of doing this? Was Galileo expecting to see so many stars? What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? ffmpeg is a CLI tool and it has a lot of options that is nice to know. FFmpeg supports hardware accelerated decoding and encoding via the hwaccel cuda, h264_cuvid, hevc_cuvid and h264_nvenc, hevc_nvenc modules. I hope you found this information as useful as I did, if you have any thoughts or feedback please let me know! It is faster by two orders of magnitude than libx265, but has some drawbacks. They claim that a 4K video coming into their site should optimally be 35~45Mbps when encoded with the older x264 codecs. Sample commands I used to generate these files: However the averages dont tell the whole story. This should work in your command line. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. 31 is recommended for 1080p HD video: ffmpeg -i input.mp4 -c:v libvpx-vp9 -crf 31 -b:v 0 output.mkv In this article, we will learn about codecs like VP9 and H265, and how we can optimize video using ffmpeg tool. How can I recognize one? CEO at Pixel Point and software engineer with 10+ years of web development experience. 3 seconds at the start is nothing as long as the movie plays fine. 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? The CRF videos were done via Handbrake using x265 10-bit, whereas everything else was done via ffmpeg using x265 or x264 8-bit. Learn more about Stack Overflow the company, and our products. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? There is currently a serious lack of data on compressing 4K HDR videos out there, so I took it upon myself to get learned in the ways of the x265 encoding world. But that is all hypothetical. Would the reflected sun's radiation melt ice in LEO? libvpx-vp9 has the option -deadline which accepts following values: Time to switch to H265 and libx265. With ffmpeg, it'd look like this: ffmpeg -i input.mp4 -c:v libx264 -crf 23 output.mp4 For x265, the default CRF is 28: ffmpeg -i input.mp4 -c:v libx265 -crf 28 output.mp4 For libvpx, there is no default, and CRF can range between 0 and 63. FFMPEG gop settings. @llogan. Making statements based on opinion; back them up with references or personal experience. Have you seen the h264 & h265 pages? 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? And bitrate directly correlates to file size. In the same breath, note that NVIDIA has explicitly disabled interlaced encoding on Turing across all tiers, even the 1650 uses the older Volta NVENC encoder. At what point of what we watch as the MCU movies the branching started? I wanted to thank you for all this great work youve done on these articles. You canread thisdoc for more info on this. Planned Maintenance scheduled March 2nd, 2023 at 01:00 AM UTC (March 1st, We've added a "Necessary cookies only" option to the cookie consent popup, How to specify CRF quality settings for different encoding software, Trying to sync audio in mpeg2 video whose video freezes first 8 seconds in playback, FFMpeg concat demuxer corrupted output (freezed video on some concatenated parts). These gains will be most pronounced at resolutions of 1080p and higher. Theoretically Correct vs Practical Notation. Connect and share knowledge within a single location that is structured and easy to search. Anything from 18-40 could give a very decent quality level. is there a chinese version of ex. I used a three minute 4K HDR clip, using Handbrake to only modify which present was used. Think of video format as a container that defines file structure for carrying video and audio streams. rev2023.3.1.43269. 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. Even if your source video doesnt use the HDR color space, it compresses better. Press question mark to learn the rest of the keyboard shortcuts. The CRF scales for x264 and x265 do not correspond. It works if I specify the output bitrate, but I want to know how to figure out the proper bitrate? CRF works just like in x264, so choose the highest value that provides an acceptable quality. Why are non-Western countries siding with China in the UN? Help with ffmpeg settings H265. Both values result in a very similar bitrate for both videos, just a syntax difference due to different accepted number range. When the device you are going to watch it on doesnt support it. Connect and share knowledge within a single location that is structured and easy to search. For better visualization, I am going to show you how applying different options to ffmpeg decreases the file size and changes the quality. The webm was quite small, but take many times the amount of time that mp4 took. ***### 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. Thanks for contributing an answer to Stack Overflow! Thanks for contributing an answer to Video Production Stack Exchange! Thanks @szatmary. Code Calamity 2023. But that's probably not what you want. Applications of super-mathematics to non-super mathematics. 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. Because if every frame was that good, we shouldnt need more than 6Mbps x265 or 10Mbps x264 4K video. 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. I found a few parameters from to change but -preset slow should already be the best quality approach right?

Find centralized, trusted content and collaborate around the technologies you use most. Now this is an apples to oranges comparison. The normal wisdom is to use the the slowest you can stand for the encoding time. Please read the new article for saving HDR.I have historically been using the older x264 mp4s for my videos, as it just works on everything. Using ffmpeg for streaming video composition from Python : why the sound is cut only when streaming into a mp4 file ? Not the answer you're looking for? 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. Suspicious referee report, are "suggested citations" from a paper mill?

Ackermann Function without Recursion or Stack. Over 8 Mbps for most 1080p content with x265 is plenty good so you definitely don't need to use the slowest encoding settings. 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. Does Cosmic Background radiation transmit heat? Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? 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: First thing I did was to chop out a minute segment and promptly remove the HDR. ffmpeg creates large compressed files for tiny videos? There's a TLDR at the end. 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 ? Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. You can list private options available in this encoder with ffmpeg -h encoder=libx265. The number of distinct words in a sentence. There aren't some commercial products based on x265 nowadays?

Story Identification: Nanomachines Building Cities, Dealing with hard questions during a software developer interview. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? What are the best settings for me to use when encoding x265 videos? See HWAccelIntro for information on supported hardware H.265/HEVC encoders. Another flag you can pass is -movflags faststart. Something wrong with reddit clipboard. If you look at the PDF I linked in the last comment, there are many encoders out there - most proprietary. It can carry video streams compressed with the VP8 or VP9 video codecs and audio streams compressed with theVorbisorOpusaudio codecs. As I'm new to this, I tried doing some research and found that mostly it's about choosing the correct CRF and preset, so I am thinking it would be sufficient to write a script which iterates through these, creating samples which I could look at and decide what's the best option for a given (set of) video(s). ffmpeg -framerate 30 -i in.265 -i in.avi -c copy -map 0:v -map 1:a -video_track_timescale 1k fixed.mp4 Replace the framerate value with the true rate of the video. Add it next to your -c:v h264_nvenc -c:a ac3 You should also be able to push 2 sessions. (if you go higher than 4.1 preset). 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.
