Best crf for 1080p reddit For a same CRF a 2 hours cartoon can have a final size of 3GB and a 1h30 movie 6GB. 5 - Preset: slower - Output depth: 10-bit. New 1080p encode at 126 kbps in comment below!. Though, NVENC will always by limited in quality by its lack of CRF rate control. Good In order to get the best possible quality at the smallest possible size, it will be a VERY slow process. At the CRF levels you're using, SVT-AV1 will naturally remove noise anyway (as part of the compression process), and feeding in the original image helps retain high-frequency information/reduce blurriness from But with CRF you can end up with very high bitrate spikes that may be a problem for streaming over poor connections. All video resolution to follow original, and only downscale to 1080p if it's above. My OBS Output Settings. Practically indistinguishable from source material unless you zoom in to pixel level. Check hardware unboxed or just google best 1080p GPU and look at one Historically i've always encoded them down to 720p at 22 CRF using x264, but having recently picked up a 4K TV for the living room, the quality doesn't stand up for me any longer. 720p only looks marginally better for twitch than 1080p for the AMD encoder, so Custom upscales from 1080p sources? I know, I know - should have checked more carefully! So, who is actually putting out good "genuine" encodes these days? DDR/DTOne seems to pop up quite a bit at a reasonable 20GB size range (if I want to watch my storage vs remuxes at 50GB+, but maximise quality where possible) which I think are mostly at CRF 16. I recently tried a couple H. Personally, I use CRF 17 for both 1080p and 4k. For recording and YouTube, use amd hevc encoder CBR 8000 preset quality profile high 1 b frame. If you don't lower your resolution but do continue to shrink Very bright content (e. What is the good average constant quality setting for AV1 in comparison to x265 in 1080p and Off the top of my head: ffmpeg -i input. The file size of this is then noted and all other encodes have their CRF values changed to match the file size of the 4K encode (4. Always use CRF/RF if you want the smallest file size and consistent quality. I'm using preset 5, but What CRF should I use for 4k 24/30/60fps Content, that is a good balance of 5-bit x265 encoding at 1080p results in a file size of 921MB and quality that looks (to me anyway) as good as the original Blu-Ray. Conversly, older titles will still end up shockingly large, mostly due to grain/noise. I still personally think CRF set on a higher quality level gets me a better overall picture (talking 30-35 GB for a 4k movie, 5-8 GB for a 1080p not counting the audio), which I definite as "pretty close to the original even if not totally indistinguishable". Decent settings for 1080p streaming/recording? A bitrate of 6,000Kbps is already half of what should be used for 1080p. You can run your 4. If you want the file size smaller, continue to shrink bitrate or lower your resolution. Are there graphic settings I could change? Anything at all that I could try to get the higher quality? I've tried everything on SLOBS at this point. Best compression with good quality CRF 18 for 1080p. 22\24 are the standard when using x264 codec. In short, I'm very happy with h264, CRF 18, slow and CRF 15, slower encoding options for Quest 2. I know for YouTube, 25-ish Mbps is fine, their VP9 encode becomes a bottleneck here (from my experience), probably even fewer bits considering I actually scaled up my 1920x1080 recordings to 2560x1440 @ 25 Mbps. Always use 10bit to help with efficiency, reduce banding and overall better colour accuracy ( Even if your source ks 8bit) Always use P7 and don't sacrifice that for speedups, I recommend a lower crf because the vmaf only looks higher due to some preprocessing done by nvenc like denoising and sharpening, less detail is retained. You can use average bitrate encode if there is a reason you need to target a particular file size even if it means the quality level used may vary, and you don't mind that the encode will take nearly twice as long. View community ranking In the Top 1% of largest communities on Reddit. 12kbps, Audio bitrate: 40. constant quality: RF 15-20 depending on source's movement and grain, and ultimate file size (run some test files on the middle parts of the movies - this will give the best estimates) lower RFs give better quality encoder preset: slower (I've found to be the best at speed vs actual quality) If 1080p then I suggest a Constant Quality of 22-20 (the higher number, the lower file size). NotEnoughAV1Encodes is great for AV1, I'm not savvy enough to get AV1 to grind all my CPU cores without it. Login to twitch in the stream tab and click ignore streaming service recommendations. As in, multiple days per hour of video. I use VMAF calculation de determine which crf I will use (on tv shows the gain are substantial) Anything averaging 93% or above indistinguishable from the remux I usually end up with files around 30% to 50% the original size and crf between 18 and 22 depending on the source Compressing audio can be a great place to reduce file size Good point too is to use x265 It’s probably best to figure out your time requirements, and then figure out what options give you the best quality within your target time, and then what size you can get down to at your target quality. For 1080p, NVEnc HEVC, I definitely had to use more than 50 Mbps once I started caring about visual quality. The CRF is just a level that you can adjust with the SAME profiles and same settings, means if you have x264 preset slow and x264 preset slower with the same CRF you will not have the same result. Anything smaller I can see the pixelation and blockiness or it has audio super compressed and I have to fiddle with the remote the whole time. CRF is a target quality mode instead of giving a bitrate range. 265 10-bit (x265), RF (not RQ) is a Constant Quality value, that indicates a quality threshold (relative to all the other settings, not absolute) where larger number is lower quality, Preset veryslow means it takes longer to process as it takes more information into account (which results in higher quality and smaller size for a given RF {for Slow preset honestly is the biggest suggestion even though encode times will be way longer. It seems a bit foolish to compare rf numbers within the same codec while changing settings, let alone to a different codec. My rule of thumb for H. Source video is a 1080p 60fps file being downscaled to 360p 60fps. 1080p on my 55" 4k looks "good enough" from where I sit and I rarely have my glasses on when relaxing. A 1GB 1080p AV1 movie is very doable at pretty good quality. Fixing this by setting a maxrate works for both modes, CRF and 2pass-with-target-bitrate encoding. First is with the same CRF (60) for all resolutions. All full side by side ofc. 90kbps So what crf would be ideal? I tried 26, but the final output had a lot of judder from dropped frames I guess. Don't see any difference to higher quality encodings aside for the blown-up filesize. Comparing them isn't easy. However, I have a bunch of high res (1080p) but low bitrate (3Mbps) videos. Make sure you replicate any issues as best you can, which means having any games/apps open and captured, etc. Though the length of time will depend on the profile you use. Turn off CBR, then set a CFR by putting "CRF=X" in the x264 parameters field under advanced. 1 audio, 3 subtitle languages, and it looks really good, sometimes even better than the original Blu-Ray due to less blocking artifacts introduced by the AVC encode. CRF provides the best compression for the best quality. com find Get an ad-free experience with special benefits, and directly support Reddit. g. With that, encoding a 1hr 50m h264 file with 8bit, 1080p, 10k bitrate VBR and EAC-3 640kb/s audio to HEVC, 8bit, 1080p, 6k bitrate VBR and Opus 320kb/s audio can take all the way down to 8 minutes in Staxrip. Not sure if it made sense, it just worked for me. Higher Resolution with lower CRF values, buy more hard drives. I personally can not stand HD video with low bitrate, the encoding artifacts and color banding drive me mad to the point I actually won't watch it. Try CRF 17 for a very high quality video (smaller value = higher quality = larger file size). Edit: Specs CPU - Ryzen 3900X GPU - AMD Radeon 5700XT Under the Video tab, Video Encoder H. From what I have learned, I have not seen a reason My goal is to save space on my stored 4k H264 content, without noticeable quality loss. Experiment with the CRF value until you achieve a quality and file size you’re happy with. I think you're good. From my FFmpeg cheatsheet: *** CRF 20-23 for most 1080p videos is enough. We'll see :) Chat-gpt recommended CRF 22-24 for h264. One thing of note for 1080p it’s also very CPU dependent. The preset “veryslow” yields best results. Obviously, these older titles are only ever tested at low CRF values and I know full well they'll need to go higher, but my method uses a CRF of 14 for the samples and predicts (reasonably well) which CRF is needed to not exceed my 20,000kbps limit. Would lowering the default CRF use the following search parameters to narrow your results: subreddit:subreddit find submissions in "subreddit" author:username find submissions by "username" use the following search parameters to narrow your results: subreddit:subreddit find submissions in "subreddit" author:username find submissions by "username" site:example. I use bitrate and 2-pass encoding with my tuned presets in handbrake. 5 times larger (110GB) than the Blu-Ray source. to measure the quality compared to the I'm using DAIN APP to interpolate videos and their default CRF is 16, but as I have to use the VRAM reduced usage setting a 1080p file is reduced to 540p in the output file, so I'm losing quality. It would be better to copy the audio instead of reencoding it. never go above 30. 2pass encoding with a given target bitrate has the same problem. What I find suitable for h. Maybe I've just been spoiled, but x264 has such good defaults I have a hard time justifying changing them, crf 23 is a few points below almost visually lossless making it a good quality vs size trade off, and and "default" preset is a good trade off between performance and size, I usually just adjust the crf to 16-18 and have visually lossless encodes 99% of the time, and if I have The point of CRF is that you specify a compression level and it scales the bit rate up and down to meet that - if you use CRF, you have no control over bit rate. eg: 480p > 480p, 720p > 720p, 1080p > 1080p, but 4K > 1080p, 1440p > 1080p All video to H265. 17 votes, 27 comments. But in exchange, the result will indeed be as small as possible while still maintaining quality. 5MB). Frames: 13,918 (3:52:11), Total bitrate: 120. These options are what I've found in some recording testing today (will be streaming later to test if the quality looks as good live) to be the best settings for decent high quality pretty clear streams when running high FPS, and getting Record at 720p and upscale it in your editing software, it might not look as good as native 1080p but it will look better than 720p because it will get a higher bitrate on YT. The difference is how they end up at those bit rates. CRF 15 encoding = 920MB CRF 26 encoding It depends, some games can look good at 3Mbps, some don't look good unless they're 50Mbps, this is why we have CRF; it dynamically changes the bitrate to fit the quality of the image you want. I've been experimenting with some episodes from season 1 of Downton Abbey, with the aim of retaining 1080p and maintaining a decent standard of quality. In CRF mode, the numbers go from 51-0, different settings will change the effectiveness of this number, and diverse content will respond differently to compression. Plenty of videos out there to help decide this as well. Not sure what that encoder calls it). SVT-AV1 is fast if you have lots of cores, but isn’t the best quality. 265. Next the Encoder Preset (Sample Speed - Higher=Larger file size) - for any action I would use Very Fast, no significant action, maybe Medium or Slow. Officially the BEST subreddit for VEGAS Pro! Here we're dedicated to helping out VEGAS Pro editors by answering questions and informing about the latest news! Be sure to read the rules to avoid getting banned! Also this subreddit looks GREAT in 'Old Reddit' so check it out if you're not a fan of 'New Reddit'. Software AV1 is not exactly feasible for most CPUs, but the M1 Pro is quite strong. A 720p video will not look as good as a 1080p unless the 1080p has lost a lot of detail through compression. CBR (constant bit rate) is great for streaming, less for recording. cartoons): Increaes your CRF by 5+ You may not spot the difference if you don't do this, but believe me, as soon as you watch the encode on a good, bright TV, you will notice how smudgy everything is, simply because 700 kbps is NOT enough to get a clean 1080p image in almost all cases. Crf 17 is to add bits. Unless you have specialised requirements, deviating from the presets without in-depth knowledge Actually, RF23 is going to look pretty meh for 1080p, if you look closely. I dont think you could encode AOM AV1 at your MBP native resolution, but something closer to 1080p would work. Somebody on reddit said anything beyond slower is basically placebo. With some recent nightly builds, I will typically try anywhere from 22 to 26 with 10-bit H. You could use a 4k, 1080p, whatever preset. What are Your X265 Release Group as of END 2019 List: x265 [All File Sizes] PSA,TiGole,QxR,UTR,Vyndros only X264 8bit SDR & The sane thing to do when recording locally is to use CRF (with x264), or CQP (with NVENC, or maybe AMF. -v is the encoder params (here --rc 0 --enable-tpl-la 1 will enable crf as --crf itself is broken in the python av1an build, --qp 20 just will give a crf value which av1an target quality will replace so can be any value, --preset 6 is the preset go higher here due to target quality taking a signigifant performance chunk, --keyint 250 set it the 108 votes, 244 comments. So I waited about 20 hours to encode this video at cpu-used 0 and CRF 63 and I was very surprised at the encoding efficiency of AV1. Hey, Since AV1 encoding with SVT-AV1 and enc-mode 8 is blazing fast while encoding I would like to use that in the future instead of x265. Especially if you're using the 8-bit encoder. Even some stuff i used to have to get new episodes in x264, Good Eats, Top Chef, Project Runway, other basic cable shit, now shows up in x265 pretty much right away, not always in 1080p but i usually get a 720p copy of ANYTHING from MeGusta at Test your self and see which preset/CRF it's good for you. Framerate > maintain Audio > maintain CRF : 24 Rate Control - CRF Factor - 19 CPU Preset - veryfast The recording looks fine but not clean and crisp that 1080p 60fps should be. Great start! Some feedback: For low to medium film grain/camera noise, you want to pair up film grain synthesis with film grain denoise turned off (film-grain-denoise=0). 3 GB. You can lower to 18 for blu-ray and 16 for DVD to "nearly" transparent encode. x265 is a total waste of space no matter how you tune it unless you're encoding 4K HDR content or are blind to x265's inferior quality-per-bitrate at 1080p. If you use constant quality it isn't used. When I want "hairy edge" where I can tell there is compression, I use crf 26 or 30. Calculate SSIM, MS-SSIM etc. Reply eavesdroppingyou • CRF 18 is considered a reasonable minimum for DVD/480p, but if it's super low quality/blocky you might want to go down to CRF 17, for example. Reencoding it with 320 MBit/s is just going to make it larger while possibly making the quality a little worse. If you do insist on downscaling, 1440x1080 would be your best choice. These CRF values are encoder-specific, so x265's CRF 18 (which is probably what the people talking about it online meant) is not the same as some other encoder's CRF 18, even if both are HEVC encoders. OBS FPS and missed/skipped frames. Note: I recommend VBR/two pass for the highest quality, but I'm not sure of the commands. They define how much data to disregard (to get achieve a specific quality) but will not give you the same quality across codecs. Just experiment with the CRF/CQP value until you get footage that looks good, and the encoder will automatically take care of the bitrate to match that level of quality with whatever you throw at it. I would highly recommend RF20 or better (meaning lower number) with 10-bit H. Best way to record 1080/1440p 60fps with OBS For recording, you don't want to specify a bitrate, you want to specify a CFR. mkv. if you want x265 you can start with CRF20, slow preset is a good start to test, but for blu-ray movies I prefer x264, it's better in my opinion, much sharper and detailed (even with the sao option off). Going below 15-16 will usually not yield much benefit anymore (diminishing returns). Really if you have enough indexers set up and cast a wide enough net you can get most everything new in x265 nowadays. anyway dont try lossless quality on OBS it would go between 160-230mbps i tried it once and thats way too much just type "The Best Bitrate for Recording Gameplay" on youtube this creator explains bitrate difference the best way i found possible cause other videos are either dont tell you everything or clickbait nonsense or just outdated Also, if you upload to youtube in 1080p, the bitrate it will compress to is going to be significantly lower if your a smaller channel, and in order to get the better codec that bigger channels get along with better bitrate, upload in 1440p or 4K My impression is that for high quality videos, crf=20 gives a good result that's indistinguishable from the source with naked eyes. So I would take those suggestions with a Decomb EEDI2 Bob does astounding good deinterlacing. Most YouTube gaming channels have don’t tons of testing. 5gb through handbrake at very slow and get smaller file. When you compare aom and SVT side by side you will see that the cq implementation of aom struggles with dark noisy scenes while crf on SVT or x265 will heavily bump up the bitrate on those so that it will look good. Also, the video looks good only if you watch it in 1440p and looks worse in 1080p. The CRF is not even the same on x264 different presets. That's like, 5 Mbit for the video stream then? I alternate between 23 and 22 for 1080p. If the source is 480p, that is what you get, only thing changing is the RF. So there's a reason why the quality setting on aom isn't called crf. And while a less than 1080p resolution with a higher bitrate isn't as terrible to me it can't match higher resolutions to my eye. However, I almost never use crf anymore exactly because of sporadic results. CQP is Constant Quantisation Parameter, which works in a similar way, except instead of specifying a constant compression level for the whole image, it specifies it for the macroblocks. ", but since VMAF is from netflix I think its geared more towards streaming, which generally has less quality than local playback. Two examples: Even if you set the bitrate on CBR to be the peak of what you may get on CRF (say 40,000 Kbps), the quality will be relatively terrible. Slow pass of AV1 at CRF 28 (file is mislabeled, oops) saving ~65% with OK VMAF scores in my opinion. get reddit premium. A lot of people will get a low quality release because they have a low res TV or they take a good quality video and compress it to 1/2 the size or more to save space and watch it on their low res TV. Then transcode to HEVC with handbrake I'm personally not a fan of downscaling your video unless you need that for compatibility reasons. These aren't good x264 settings. 21 is on the lower quality / lower file size end, while closer to 18 increases quality but also file size. Hey all! These are my settings for OBS to stream at 1080p 144FPS to Twitch. I used different CRF settings for different resolutions: 720p or less (CRF18), 1080p (CRF20) and 2160p (CRF22). This suited me fine both in quality and disk space and I sort of came to this approach over time. It's a number I reckon is good for most situations. I've read that 15-17 CRF encodes are good, and I've also heard good things about groups like Tigole (QXR), IAMABLE, and TERMiNAL. So, for good color, some action, source 1080p, I would use Video Encoder H. Is 93ish reasonable? Or should I go for 95, 97 2 pass encoding is only used for average bitrate encodes. The CRF is the good parameter to set, it choose itself the bitrate it needs to encode for a selected quality. With two-pass you set the bit rate and Handbrake reads the video on its 1st pass to work out how best to apportion the available bit rate, on its 2nd pass, depending on the complexity of each frame. 264 software encoder for Handbrake. Some encoders don't even call it CRF, even though they have a setting that works the same way. A similar video with 5k bitrate but 1080p res compresses seamlessly with crf 26, but the 4k is the problem. *** ### Encode video as x265 HEVC 10bit. 5Mbps when viewing on a 55” OLED TV from 7 feet away. Whereas CRF 18 for Blu Ray quality 1080p is a waste of space and time - CRF 20 is generally considered to be a reasonable "lowest" value for that. true. As was mentioned by someone else, the practical limit is that it can never give you more quality than the source but an equal limit is the settings of all the so-called "psy-optimizations", AQ, MB-TREE, PSY-RD, PSY-Trellis, Trellis, etc, that all - upscaling the 1080p video to 1440 and uploading it to YouTube just for VP9 is useless unless the viewer watch the video in 1440p (which most of the people don't bother and just watch it in 1080p). SVT-AV1 supports crf. Instead of targetting a specific bitrate and varying . Nope, your quality settings affect the filesize, not resolution alone. Make sure you force the output frame rate to 50 fps, of course. If you are testing differences between codecs it's best to use bitrate. YouTube's 1440p quality can still be worse than a local 1080p copy, but YouTube's 1080p is horrid unless you have VP9 instead of AVC1 and are a larger YouTuber. CRF + maxrate = constrained constant quality. I did a little searching on a private tracker I'm a member of and from what I can tell Tigole has the smallest HEVC does not have a "CRF 18". That being said, what are you recording in? Because if your recording software allows you to record in a different rate control, like CQP, CRF or VBR, you should. Increase the CRF instead if you want smaller files. 265 at 1080p is: RF20 if it's something I don't care particularly much about RF18 if it's something important - CRF: 27. The 1440p encode was coming in at either 300kb/s over at CRF 60 and 300kb/s under at CRF 61. Use CRF 23+ for videos in 4K. mkv -c:a copy -vf scale=-1:1080:flags=lanczos -c:v hevc_nvenc -b:v 18M output. No QP (and CRF) are coder specific and not universal. Your bitrate will increase as you change to 1440p from 1080p, since CQP is about visual clarity first and foremost, but that's still more efficient in space than CRF for the same visual quality, depending on the game. It started development in late 2014 and ended June 2023. A veryslow pass of H264 CRF 23 saved ~25% of the size. If you use the 720p preset it will set an upper limit of 720p. Another note: This doesn't account for HDR. Now topaz doesn't give you any other encode parameters such as "very slow". 265 (no QVC), Q 20, Preset VF. View community ranking In the Top 10% of largest communities on Reddit. I've been using AV1 for about a year and a half and with recent builds of AV1-SVT, I've been using this as a guideline for encoding typical 1080p Blu-rays: Good: CRF 30, Preset 8 Better: CRF 27, Preset 6 Best: CRF 24, Preset 4 Plenty of people will @OP, CRF is a bit rate control method, lower CRF values will produce, in theory, higher quality, because they use more bit rate. 264 encodes on a noisy 4k remux of Blade Runner to 1080p, no options specified but set VerySlow, and I would've gone with CQ 22 at 5. On the 10-bit x265, crf 18 on slow is is actually slightly better than crf 16 on medium, and the file is is also smaller! This means with your current In general, with 1080p footage, you never want to go above 15,000kbs for any medium, whether it's youtube or TV. Recommended sane CRF values are between around 18 and around 21 and this is the main knob for finding that balance between quality and file size while still maintaining a pretty good disk space saving. 2kbps, Video bitrate: 71. Notably, there's Very Fast, Fast, Medium, Slow and Slower. I’m getting great results with most 1080p content if I aim for an average video bitrate of around 4. 10 I encoded a 1080P Blu-Ray movie using "CRF 0". Going from 4K to 1080 should reduce file size. The upscaling is first reversed preserving native 1080p elements and various issues are fixed along with upscaling it back to 1080 before the final encode. Reddit won't allow me to post links for some reason, but scroll a couple of days back through my post history to find out how to optimise 8-bit x264 for 1080p encoding with FFmpeg. But there's a good argument for constant bitrate if you have the hard drive space. Seriously though, if your recordings arent too long, I would record Apple VT H264 with CRF at native resolution. I think CRF 20 still looks pretty good while making the filesize small (200-350 MB). However, the best encodes are still 1080p and some of them are made by employing something called descaling where the native resolution and upscale method can be deciphered. CBR and 2-pass ABR both sacrifice either quality or space, and you no control over which. I've also used some more finer tuning parameters to make it more efficient for the x265 encoder, and it generally gives me as good quality as youtube's generated vp9 videos at a lower file size, and I was hoping to further improve the bitrate with AV1. 265 encoder. Stop your stream/recording. Generally I do good encode for blu-ray at CRF20 slow or veryslow and CRF18 for DVD. . The beauty of x264 and x265 is they come with recommended presets, which contain a whole set of settings. Upgrading the quality of some of my titles what bitrate, file size and codec do you aim for with 1080p movies? file size and codec do you aim for with 1080p movies? My specific settings - CPU x264 CRF 20, Slow, Encoder Profile Main 4. handbrake join leave 12,224 readers. 264 is 2 Mbps for 720p Select and encode small segment (that best represents video content) using different CRF values/other settings. This week I'm trying out Avatar 2 cd 2 but with h265 (CRF 22 slow and slower options). 1, Encoder Tune (dependent on I found " Real Networks wrote a white paper in the subject and they found that VMAF 93 is a good value to target, but everything with an average over 90 will look good. Apollo was an award-winning free Reddit app for iOS with over 100K 5-star reviews, built with the community in mind, and with a focus on speed, customizability, and best in class iOS features. So between 2 different encoders it's worse. While CQP on NVENC is great for quality (and is a little higher quality in fast scenes than CRF), it does little to nothing for compression. Also use CRF rate control with a factor of 18 and a veryfast CPU preset for best recording in terms of quality to filesize to performance. Using the same encoding settings, a non-turbo two-pass and a CRF encode are visually identical at the same bit rate. The output ended up 2. Select Help > Log Files > Upload Current Log File. x265 uses CRF 18 by default. And that's for the x. Second is an encode in 4K at CRF 63. Until now I always converted my videos to x265. If it's too space demanding, you could always reencode it again in ffmpeg but have a maximum bitrate so when the scene is intense, it looks worse, but it - General x265 notes: Always 10 bit, Main 10 is almost always good enough, don't tune the level since it can result in non-deterministic behaviour, prefer mkv over mp4 (mkv can sometimes have compatibility issues, but is a lot more flexible as a container format) - x265, very decent quality: slow & crf 19 - x265, okish quality: fast & crf 21 I've made extensive comparisons with my personal tuning for x265 last year (default tunings for x265/HEVC encoders are not really that good for preserving fine detail) and found out that AV1 washes away more fine low contrast detail than x265 at resonably bitrate levels (which is something difficult to quantify, but equivalent to around CRF 22 I also made a 1 CD encode: at CRF 34 with film grain synthesis, 5. Most of my bluray rips end up about this size, and they look very good to me. dbxtyk lswqrn pmffh abtao ruj lelj vewmnij kgl uct txooae
