Ffmpeg best h265 settings reddit. and I opted for -crf 22.

Ffmpeg best h265 settings reddit For me, H264 renders around 2x slower then H265, though the file sizes are much smaller for H264 then H265 (opposite of what everyone said is supposed to happen). Right now I'm leaning toward . Also thanks for the settings. Again - the culprit is the camera, but gstreamer somehow manages to handle it better. Just use a faster preset if it's too slow. Suddenly it started producing completely garbled/green video Alright heres a weird one. Animation tuning will look great on 2d hand drawn anime, but awful on 3d computer animation. They look great now, but some programs hate AVI. Frequency Response: "The analysis of the frequency spectrum of each Im getting quite a lot of judder compressing a 4k video @ 5k bitrate with 26crf H265. This could be easily done with some 5 minute ProRes test file and some bash loops in linux systems, but I wonder if there is a way to automate the comparison of the results? Pretty sure that the output format of DaVinci Resolve (free) is quite limited. GPU transcoded videos are normally lower quality and/or result in larger files. I have a camera that produces a h. Keep in mind that h265 has higher system requirements for playback and older hardware cannot play that codec. In general, though, from what I've read NoteEnoughAV1Encodes is really smartly designed and is by far the best bang-for-your-encoding-time option, should have really good default settings, and should be much simpler to use than any command-line option. After that, I want to delete the h264 files. I am looking for my "perfect" ffmpeg command, so that i can queue all my movies, hit enter and wait a few days and after that my whole collection is now h265. If you go to their gitlab page and scroll down, there's a ton of info. Hi all,I need to convert several PNG image sequences to h265 videos at the best quality possible,this is the string I'm using at the moment, is there something I can add or modify? ffmpeg -r 60 -f image2 -s 4096x2160 -hwaccel cuda -i SEQ_%04d. Google searching tells me also RTMP is not an option. FFmpeg Quality Setting on Tdarr Flows for HEVC Hey Guys! hoping I can get some clarification. it’s a way to specify a fixed quality of the video. ffmpeg -i INPUT -c copy -bitexact -map_metadata -1 -bsf:v 'filter_units=remove_types=6' OUTPUT. Although, settings in placebo preset can raise the size but the quality will be better due to a higher precision. I'm not sure what the hell is going on with those options. 1 audio. I know the crf values aren't equivalent between the different encoders, but these settings get roughly the same filesizes for the demonstration: I'm wondering if I use the same settings Does Handbrake use the same library for h265 that ffmpeg? I'm wondering if I use the same settings (x265 slow) in both if I'll get the exact same quality. In principle, only CRF determines file size for a given video stream, and all presets result in the same size (within certain bounds, with random Its not visible in the few scenes I tested, but I am not sure if the difference is not visible in everything. mkv -b_ref_mode 0 -c:v hevc_nvenc -cq 1 -preset p7 -tune hq -c:a copy outputp. Play around with the settings if you're interested and have time. Glossary: . Looking for x265 encoding box - best CPU This rig gives consistently cumulated ~60-80 fps at 1080p with my desired setting when running 4 instances of ffmpeg. Can anybody help? My goal isnt totally lossless, but minimal loss is ok. While that may be superior in some ways, most editing apps cannot open these VP9 I'm converting almost of my video from H264 to H265 to gain some free space on my drive. By the way, NVENC HEVC is not "X265". I have a pretty beefy computer, so time to encode them doesn't really matter to me. I've finally been able to get it to allow me to do H265 -> H265, but only 8 bit, and no b frames. Another note: This doesn't account for HDR. It's setup to use The short version: It is more storage space efficient to re-encode larger files to HEVC/H265 CQP24 via ffmpeg than it is to record them at those settings right off the bat. if you want more compression at the expense of visual quality, you might opt for -crf 30 instead of 26. *** ### Encode video as x265 HEVC 10bit. When transcoding with ffmpeg the file size shrinks to between 1/2 and 1/3 of the original (using the plugin "Tdarr_Plugin_075a_FFMPEG_HEVC_Generic"). apparently is doesnt exist anymore. Just a balance between quality, file size, and encoding time. FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter Of these 4 setting which one do you think is best? -crf 21 -preset medium -crf 20 -preset fast -crf 20 -preset faster -crf 18 -preset superfast Using some sample trials of encoding a minute starting from middle of some videos using -ss and -t, these 4 settings yields about the same filesize. 265, not h. 264. js it evaluates the source material and does it's best to choose an appropriate bitrate and such to give high quality output. Technically AV1 might be even better but it's not really supported by anything yet and encoding times are atrocious. How w can I speed up the process? I will preface this that I know next to nothing about ffmpeg. Although I've been getting better results with superHQ h264 w/animation filter, then running ffmpeg-normalize on the end result as the x265 seems to me insanely good compression defaults It's an extra step, but I swear it's better end result (might be placebo though). mp4 I guess you are satisfied with the quality output from Topaz at 35gb so your options to reduce size with best quality are: Try ffmpeg at CRF 19 and preset slow using h. A Ninja V recorder I use now records All-Intra H265 10 bit 4:2:2, which edits beautifully in Davinci Resolve using Intel 11th gen HW acceleration. ffmpeg uses x. My flow is working great, however, I don't mind the conversion taking longer but I want to keep as much quality as possible from original but obviosly lower the size. I'm using: ffmpeg -i videoname. Have just a quality slider. For audio, I keep the original streams. . For AMD VCE If you're using bitrate based encoding specify a lower bitrate (that directly effects the file size). 4gb size. Its not music, so i dont think difference will be that big. x265 will be both faster and score higher on objective measures with psy-vis disabled, even if it looks worse to actual humans watching the video. What command do I need for ffmpeg or is there a program that will do this? -c:v libx265 -x265-params no-info=1 this does removed it but it converts the whole file I want to do this by simply removing only encode settings I want simply copy the file -c copy without converting I want my video quality be untouched when I remove encode settings. I'd done this with the Handbrake gui, Handbrakecli, and ffmpeg. Otherwise I'm sure you already know about finding the encoder specific options with ffmpeg -h encoder=hevc_qsv and just fiddling with the parameters and checking PSNR/SSIM/VMAF until H265 w/ correct resolution and animation filter. now sao=0 was something I was looking for, thats how I found your comment, but the rest is pure gold. Though, re-encoding footage is usually not a good idea. I want to compress that with H265. If I use ffmpeg, I am seeing mostly the grey background with moving objects and occasionally picture gets clean to just get blurry again. I have been encoding with an untouched bluray file trying to get some decent quality out of it. Anyway, h265 lossy at sufficiently high quality (maybe crf18 or lower) is generally gonna look almost identical to I've been using Tdarr for a while to re-encode some video libraries without issue. What is the correlation between the preset and crf? I encoded the same video using crf of 20 and medium preset also with crf of 20 and slow preset. If that's not a strict priority, they're really fast though. Did you disable the psy-vis options in x265? Otherwise using objective metrics like SSIM/PSNR/VMAF is misleading at best, and really dishonest. Because I had problems at first with the above plugin I also tried one, which uses handbrake to transcode ("Tdarr_Plugin_s7x9_winsome_h265_10bit"). mp4. You can start with -svtav1-params tune=0:keyint=5s and try different presets. It doesn't matter if it's not music, you're suggesting people re-encode their (possibly lossy) source to a low quality 160k encode then upload it onto a service such as youtube that will re-encode it once again it will sound horrible. My question - are there any settings/flags I can pass to ffmpeg that will help it process it this stream with less artifacts? When using x264/x265/svt-av1, I generally don't do more than setting a preset and maybe the tune option. The only time H265 files are smaller for me is on the extreme high ends and low ends of bitrate (120000+ or 25000-). If I convert from h264 to h265 under the same ffmpeg quality settings but changing only the codec: for example I'd use nvenc_hevec instead of libx265 because it allows native nvidia conversion (and I've a nvidia gtx1070, so the process is much faster), in this case or in general, a similar choice make the output file different or is exactly the same file ? There's no magical secret to make it go faster while not losing compression efficiency. Use the live preview button to check your settings against a small section. My understanding is that slower presets lead to lower file size while retaining similar image quality as other presets. I screwed up my DVR and recorded too much I use Tdarr to re-encode and homogenize my library. If you're using quality based I've found 5 seconds to be good enough for seekability and compression. e. mkv to . A 4K remix should already be HEVC/H265 If you do really to convert, when I wrote a powershell script to convert my library I created a comparison chart of using various ffmpeg setting for a sample file. I'd up the bframes to ≥8 in Handbrake's Advanced Options and maybe zone the credits too, especially if they're long, at b=0. I've seen many people have this issue. Depending on your settings I guess. Encode some random segments from typical inputs. The Turing hevc encoder from nvidia which you can get on the GTX 1660 (at minimum) has the best quality for hevc hardware encoding, perhaps that's the path you want to take. The higher the CRF/CQ the more quality is lost. For VMAF comparisons, the best x265 tune is probably PSNR (disables Hey assuming i got a video of 2 gb, 1280x720, i want to reduce file size and encoding it on H265 What are best settings to reduce file without sacrificing much in image quality? Keep in mind, my main criteria is reducing file size over I am overwhelmed by all the functions and options of ffmpeg. And the conversion is pretty slow. A common misconception is that a slower preset results in a smaller file. If you want better efficiency at the same or lower compute cost, use SVT-AV1. short answer yes-ish. I don't really do all that much HDR stuff with ffmpeg but last time I checked you'll need to make sure HDR metadata gets passed through (and for DV/HDR10+ you'll need to faff around with external tools). The input file is a 1 minute medium quality gameplay clip, 358MB in size. The ESP32 series employs either a Tensilica Xtensa LX6, Xtensa LX7 or a RiscV processor, and both dual-core and single-core variations are available. What settings do you have? I have only used handbrake in the past, but I'm not familiar with ffmpeg settings. it will then automatically use the best setting for the hardware encoder (or cpu if no hardware encodeer) use the "quality" setting. Choose the slowest preset that you have patience for. The bit rate is how much storage that actually takes per second. mp4 -c:v libx265 -crf 23 -preset medium outh265. 44. If you have an Nvidia GPU, use the AV1 NVENC encoder for fast Try using a faster preset with x265. Question then would be is your internet fast enough that slower uploads speeds make up for faster encodes. best comment on this. And you won't have an unusable computer to boot. It's NVENC HEVC or NVENC H265. 3 or so, to save space. Transparency: "A transparency threshold is a given bitrate value at which audio transparency is reached. Different content will require other settings and there is no one-to-rule-them-all. I've been going through this process of re-encoding 1080p/720p H. And the preset setting - from ultrafast to very slow - controls how much time you want to allow the encoder to find the most efficient compression. A 120mb h264 may well have same VFMA score to 60mb H265 ( worth testing). 15K subscribers in the ffmpeg community. 264 into H. Well, after trying to use FFmpeg and numerous other programs, DumboFab video converter is the one that actually worked. Turn it on when you go to bed, and if you do one per night, you'll have 30 in a month. I don't care much about quality on TV shows (720p is fine), but on movies I would like to keep the original quality. ffmpeg -i Knowing what settings to pick before encoding is extremely important. General Complete name H264 vs H265(HEVC), Optimize game settings. I've had the exact same problems as you. Also their common questions page. ". If you click on How to run SVTAV1 in ffmpeg there's a basic rundown that's probably exactly what you are looking for. Hello! I have been encoding for a while now and just cannot figure out how to get av1 to look crisp and clear. It's definitely going to be bigger. 1 release, my obs settings contained only x264 or h264/AVC encoder (AMD Advanced Media Framework), now I have AMD AMF H264/AVC (via Skip to main content Open menu Open navigation Go to Reddit Home No, I think you misunderstand. Before 21. FFmpeg is a great open source. My goal is, and always has been, to reduce the 4k REMUX file size so that is as small as possible, but yet retains the image as close to the source-quality as possible, as viewed on my AV1 NVENC was the clear winner with faster compression speeds, comparable file size, and better quality. Edit: The existing video is 2160p with 5k bitrate and 1. Transparency is the result of lossy data compression accurate enough that the compressed result is perceptually indistinguishable from the uncompressed input for the average listener. I'd like to run a bigger test series with various encoders (software and hardware like nvenc, quicksync) on different hardware/CPUs and with different settings. jpeg Hello everyone, I've recently come across a peculiar issue and was hoping to get some insight or potential solutions from you all. The problem with this question is that it depends on what speed setting you use. Your best bet may be a camera with onboard h265 encoding and then stream that source. I also recommend using 10-bit, as it Choose the highest CRF value that provides an acceptable quality. comp as in percentage of original size. With medium being the slowest encoding time. In a few years h265 will be the ubiquitous I just did a quick check with ffmpeg to see what it would look like if I re-encoded them with h265 and my jaw hit the floor. My desired output is 4k h265, yuvp10le. 1 AAC. Here is my parameters : -vcodec libx265 -crf 28 The result is quite decent, able to turn a 11,5gb H264 to a 1,25gb H265. make a new ffmpeg builder: basic video encode node or something. 265 lib. Hey just wondering, i am looking for reducing my original video in H265, i dont search the best quality out there but something acceptable in term of quality (i dont have 4k monitor or tv, using 1440p monitor or my iPhone/iPad for watching video) I m asking if i should use default settings, H265 or H265 10 bits? I may take this and use it for a default/slider thing. mkv -q:v 2 output_%03. What would be some recommended ffmpeg -i "$file" -c:v libx265 -crf 27 -x265-params rc-lookahead=24:bframes=16 -preset fast -tune animation -pix_fmt yuv420p -c:a libopus -b:a 64K Converted/"$file" I (2) video generated by DaVinci Resolve after applied LUT (LUT that convert Sony sLog3 to rec709) (setting h265 quality Best which generated file with size 4. for only h264 AVC! so how can you do this for h265 HEVC What command do i need to use? I want to do this by simply copying the file I don't want One of the reasons SVTAV1 is nice is that they have put a little more effort into their docs. To view options on a codec, do: ffmpeg -h encoder=hevc_nvenc. I use the commandline for basically everything in my workflow, but ffmpeg seems so weird for me. When you encode a lossy h264 video, you will lose quality, and, most importantly: It is completely irrelevant what your input format is. It doesn't matter if you do H265 > H264, H264 > H264, or GIF > H264, you re-encode the raw pixels anyway. 33GB 87Mb/s ) (3) video encoded to AV1 from the result of DaVinci Resolve using Handbrake with setting like AV1 10-bit/40RF/preset 7 (108MB), AV1 10 bits/38RF/preset 6(124MB), H265(HVEC)/27RF/preset From what I understand, a CRF value of 17 means visually lossless for H265 encoding - i. 265 stream but due to the lack of widespread browser support I am trying to encode this to h. The idea being I re-encode the existing media and save 20-50% file size. With a user friendly UI and lots of options in the menus this is by far the best converter of them all It helps you convert H. Any ideas? This is the ffmpeg CMD: ffmpeg -i mozarella_meat_stick. I have an MKV video file that's around 2GB, which I encoded to H. I want to convert a handful of videos from h265 to h264 in an mp4 container. I might stick with this if I don’t encounter stuttering while gaming and streaming. The problem I am running into originates from Frigate. 265 using ffmpeg, bringing its size down to approximately 250MB. Same with X264 for H264. x265 uses CRF 18 by default. Are there settings with NVENC that can match software encode at a high bitrate/low crf. It constantly monitors the Plex media directories and when it detects a new file it scans it, removes nonstandard metadata, converts subs to srt, removes any audio streams I tell it to (mostly foreign languages, but commentary can also be removed if desired) reorders streams within the container, transcodes from whatever I just tried out your setting and it seem a lot better and less blurry compare to AMF setting with no options. Now I wonder if I wanted to get comment sorted by Best Top New While batch converter will make it a bit easier, it won't be fast. The modern h265 encoding does much better with banding that you'll see in dark areas, so do a comparison of h264 and h265 with a movie that has dark/black scenes. ever. Slower presets have higher rc-lookahead values by default so they likely make completely different rate control decisions. h265 10-bit Using some small snippets from various 4K rips, I've mostly landed on the following for my "ideal" settings (when considering file size, quality, and encode time): . I find it's great quality but you should test it out. mov with best quality. 265 . Command here. Storage space is of less concern to me (but I don't have enough to just write raw frames then encode later). comments sorted by Best Top New Controversial Q&A Add a Comment. 4. At least for me it doesn't work, where h264 works flawlessly. I try to match encode settings the best that I can, so I use a program called MediaInfo that allows me to see all the little details of a given video file. I'm curious as to what parameters you are all using with FFMPEG to get the I'm trying to convert some of my library to HEVC to save space. Though, that doesn't really account for how different they are visually, as well as that CRF 23 on H264 (in my opinion) looks pretty awful. I was wondering what settings / script you guys use to convert your DVD movies and TV shows over to something a bit smaller while still keeping a nice looking (for DVD quality) image. For better compatibility with older hardware you should use h264, at a higher bitrate maybe 8000-10000 kbps. thanks I'm new to FFmpeg and I'm trying to extract frames from a 4K HEVC/H265 MKV video, but they are extracted the file size is unusually too little for a 4K image extraction. the lossless preset and tune make it larger than the original file i have tried -rc vbr, -cq 0) and manually setting bit-rate with -b:v 3 but the wiki says its not recommended questions: Anyways, I've been trying to convert some older h264/avc encoded files I have on a nas to h265 to save on some storage space, and while I realize it's impossible to expect truly lossless conversions, it seems really odd that I can't seem to get an h265 output file that is anywhere close to the original in quality without being significantly larger than the original file; or so close to the What would be the best settings in FFMPEG to convert these to MP4/MKV while retaining quality ok. mp4 2. At any rate, CRF is your best option for space and quality. This is so widespread that one of the first google results I get when searching for the impact of preset and CRF is a comparison of file sizes for different presets. I dont understand the documentation of ffmpeg and cant find answer on google about my specific problem. h265 10-bit Hello - I've just started playing around with ffmpeg and encoding videos to HEVC. I have no idea how to properly handle HDR in ffmpeg. mp4 ffmpeg -i input. According to the x265 docs, default is disabled. Vaapi works on MPV. mp4 -crf 23 -preset medium outh264. ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i inut. good enough for me. Open the file in MediaInfo and compare the settings with that table. I learned about VMAF and ran tests on many files shown below. It's better than h265 lossless. So what crf would be ideal? FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. Recording to a 'considered visually lossless' setting and re-encoding at those same settings may create more lossiness than desired. They want to download the best quality videos from YouTube but everything 4K and higher is encoded in VP9. Now if you're exporting losslessly in WAV (or some lossless video, which we don't often do due to the huge size) then we I've been looking for a way to calculate the bitrate from 265 to 264 It doesn't work like that. Also keep in mind that each reencode, no matter the settings will reduce the quality. This setting is doing nothing. ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. I have some IP cameras that encode in h265 and stream over RTSP. mp4 -c:v libx265 -vtag hvc1 -crf 19 -preset slow -c:a copy output. Just use very slow or placebo and, in the latter, change the motion estimation to umh (placebo's motion estimation is what slows down the most and causes the size to raise a bit) As I understand it, HEVC/h265/x265 cannot be streamed using mpeg-ts. From my FFmpeg cheatsheet: *** CRF 20-23 for most 1080p videos is enough. I'm seeing a 90% reduction (900MB --> 90 MB) with no discernible loss in quality. So you would probably be better off exporting to something lossless (which will be gigantic in size) and maybe even in the maximum size your source material will allow (like 4K or any weird dimensions phones output). I've been converting Blu rips to a target quality (typical movie ends up about 6-8gb at 1080p) using a pc with much better specs than you have noted, and it's 48 hours + per title. The Best Community for Modding and Upgrading Arcade1Up’s Home Arcade Game Cabinets, A1Up Jr. Try not to encode lossless video from a lossy source. I want to be able to script this hence me trying to use the CLI or ffmpeg. What settings would you recommend I use to do my base recordings I'm planning on encoding most of my blu-ray collection (largely 4K) for a Plex server. If you need lossless, use the source as-is or use h264 lossless. png -vcodec hevc_nvenc -preset lossless -profile:v main10 -pix_fmt yuv420p Y:\SEQ. I've lots of mkv files in h264 format with 2 languages of subtitle, and I'm trying to convert them in h265 (with cuda) and keep the Skip to main content Open menu Open navigation Go to Reddit Home I just found out about unmanic and I'm trying to set it up to encode my TV shows and Movies to h265. But the conversion is so so slow. I've poured over the code and it's just appending to Personally I would probably do an h265 two pass conversion at 6000-8000 kbps and see what the output looks like. So how do you guys stream HEVC/x265/h265 with ffmpeg?. Tried both JPEG and PNG, the best was JPEG. mkv. X265 is the CPU-specific library for H265. aq-mode=1 This is one of those settings where you need to do your own research and apply selectively to the individual source material instead of using a single setting apply to all approach. Every decision you make is a trade off between quality, size, and time. The GPU in question is a 1080ti but I have access to a 4070ti if the NVENC is substantially different between fast paced FPS video game footage around 500kbps That's like asking, “What's the best recipe for a cake made of nothing but flour?” I'm pretty sure libx265 achieves better results than VP9, but it's been a while since I've looked at the data. ffmpeg -i input. 265 as a space saver. 2 years later the only thing I had to change was -tune film. 1kHz etc are the sample rate for audio. I'm trying to come up with conversion settings to reduce the size of DNxHR files. View community ranking In the Top 5% of largest communities on Reddit. I would say my intention was to find the best settings to get the ultimate quality on YT and not care about render or upload times as they are one off costs. I also compared the X264 very fast and your AMF encoder settings and it wasn’t that bad to each other in term of quality. These are the settings that I would recommend. There are no perfect settings. if it's a cartoon movie it will look better by adding the -tune animation flag, if it's a grainy film it will look better adding the -tune film flag. Should be noted, in case you didn’t know, these are very basic hardware encoders. mp4 -c:v libx265 -an -x265-params crf=25 OUT. I've been using this plugin: Tdarr_Plugin_JB69_JBHEVCQSV_MinimalFile. Maybe this info output from a video will help determine some good settings for ffmpeg conversion to mp4. Normally I dont have a problem with cli applications. There are folks in the AV1 forum that are convinced that rav1e and My library has been converted from 264 (and other formats) to 256 1080p with 5. H265 encodings, all settings similar except for Encoder Preset where faster to my surprise produces slightly smaller files than medium on 5-7 minutes long test footage. Use CRF 23+ for videos in 4K. I'd expect the opposite which is the case with 264 on the same file. and I opted for -crf 22. , Virtual Pinball tables, Countercades, Casinocades, Partycades, Projectorcade, Giant Joysticks, Infinity Game Table, Casinocade, Actioncade, and Plug & Play devices. Video encoding is somewhat of an art form. CRF 28 on H265, according to ffmpeg'a docs, is approximately CRF 23 on H264. utack • You can't really make this comparison, tbh. You aren’t going to see the kind of sophisticated encodings you can get via software encoders. Each gives a great picture with smaller size, but only the Handbrake gui has audio in it. I'd definitely use even DD+@384 (but deew, not Handbrake/ffmpeg) instead of AAC for 5. 265 long answer, is that "quality goals" is a rabbit hole of options. Open a file in Handbrake, set it to do a small amount of the video at your desired settings, then multiply the time it took for, as an example, a 1 min clip to be processed by Officially the BEST subreddit for VEGAS Pro!
