1-pass encoding can be used in both VBR (variable bitrate) and constant bitrate encoding while 2-pass encoding only work for VBR. Because when it hit 100% , the game's GPU usage drop bc it got nothing to do ( CPU bottleneck ). GPU: 0. Generally, high-end graphics cards like RTX 3090, RTX 3080, RTX 2080, and Quadros are ideal for transcoding due to their higher bitrate. The GPU power is not the problem when the CPU always at 100%. Cap is 6000, be careful going above that. For more detailed info, please visit variable bitrate wikipedia to get more. but when I get to the destroy all humans remake even on low its demanding on my gpu. The faster the refresh rate, the more times the image can update every second and the smoother . The GPU power is not the problem when the CPU always at 100%. MSI Afterburner. of 1/3 of your upload speed. 2. it is true amd and nvidia are updating their freesync / gsync standards for HDR to reduce the latency that is caused by tonemapping but that tone mapping was / is happening in the Display . But still , my settings for OBS : 1080p, 4000 bitrate ( I've also tried 3000 to 6000, didn't do much ) , 60fps, Lanzcos, 2 keyframe, use 2 pass encodings. In general, the output quality of a given bitrate for GPU-based encoders won't be as high as software encoders. CPU temp around 85c is fine. A high bitrate will guarantee that a video running at a high resolution and fps will be smooth, but lower resolution videos will continue to look poor, no matter how high the bitrate is. What it does is it measures the core and memory clock speed of your graphics card, as well as other information about its internal hardware. It is vital to note that video bits are just strings of data that make up the video you watch. It can encode 37 streams at 720p resolution, 17-18 in 1080p, and 4-5 streams in Ultra HD, which is 2-2.7x higher performance than libx264 with higher visual quality. So essentially, the bitrate will improve a video's quality, but only to a certain extent. In either case - all those tests on old hardware are kind of pointless, because hardware acceleration for 4K HEVC or H.264 is relatively new and only present in the latest hardware. Since bitrate has to do with the amount of 'data bits' being transferred along with . Max B-Frames: 2 Does higher bitrate affect FPS? My CPU is an AMD FX-8350. 2. If you do not, I would think that you either has a graphics card that is not powerful enough or you are running your games in too high settings. #1 - technically speaking yes its a option for people that do have "weak" cpu's - as we continue to progress with more demanding games and our streams get more creative and populated with scenes and such, nvidia nvenc is a good option to alleviate the stress your cpu when utilizing x264. HDR does require GPU power but also adds ~30ms latency because of the way Windows deals with Tone Mapping. Also, workstation graphics cards like the ones in the Nvidia Quadro Series yield better results in video transcoding. I can play older games or games like risk of rain 2 fine. For example, if you have such high CPU usage that your PC is slow then there is a setting in OBS called Hardware (NVENC), Hardware (VCE) or Hardware (QSV) within Settings > Output > Streaming. Simply put, video bitrate defines video data transferred at any given time. In short, it is the resolution of the video and your viewers internet speed that will determine the bitrate. Profile: High; Look-ahead: Checked; Psycho Visual Tuning: Checked; GPU: 0. That means that the higher your bitrate is the higher your CPU load will be. Stream - x264 1280x720p60 2500Kbps. A very high-quality stream is generally 1080p at 60 fps. Forum Actions. Otherwise, they have little effect on the way it looks. Resolution refers to the size of a video on a screen, and frame rate refers to how often animation frames are sent to Twitch. From a streaming perspective, a higher video bitrate means a higher quality video that requires more bandwidth. And even then, unless you have access to super cheap electricity - you basically pay WAY more than 20% above rate for getting a coin. If you are using multiple GPU, your number will adjust based on which GPU you want to use. What Bitrate to Use. With the above in mind and a final answer to the question, I would say that: No, having a second monitor does not affect gaming performance and you should get a second monitor if that is what you want. The reality is, GPU encoding handles fast-moving scenes and . Preset: 'Max Quality' if you have a 20 series GPU or higher / 'Quality' if you are using a 10 series GPU. USB 2.0 also has higher latency. My CPU Usage stays around 30-50%. While Nvidia is actively working to attract more streamers to their hardware by officially supporting their own encoder (NVENC), AMD has kept AMF open-source and rely on their community to keep it running. Yes! Does video bitrate affect FPS? Recording - QuickSync/VCE/NVENC 1920x1080p60 50Mbps. With the above in mind and a final answer to the question, I would say that: No, having a second monitor does not affect gaming performance and you should get a second monitor if that is what you want. Raising the bitrate does not create a bigger load on your computer -- it's just letting it use more data for the same compression algorithm. In theory, it's true. 3. You can see watts per stream charts in figures 15 and 16. This enables the Rate Distortion Optimization in the encoder, which greatly optimizes the way you use bitrate, improving image quality on movement. Example 3: Will absolutely shit on your CPU and should be avoided in almost all cases. To get a good quality on Youtube there are 3 factors (pretty much): -Resolution. In order to get video quality as high as possible, bitrate . Higher frame rates and bigger resolutions need more bitrate to keep up with quality, just like working with regular video files. IIRC you cannot record at 2 different FPS eg. The reason you might use a GPU encoder is that your CPU is already doing a ton of work, so offloading some of it to your GPU frees up some of your resources. Let's look at some examples of setups you can use for your stream based on your bitrate. But still , my settings for OBS : 1080p, 4000 bitrate ( I've also tried 3000 to 6000, didn't do much ) , 60fps, Lanzcos, 2 keyframe, use 2 pass encodings. When I use average bitrate of 4000 rather than Constant Quality at RF 20, I get similar size and quality to CPU (x265) encoding. Video Card (GPU) Adobe has been making increasing use of the GPU over the last several years, and Premiere Pro in particular benefits from using a modern GPU. Of course, quality is a subjective term, but I believe this is where the Turing chipset shines over previous generations In terms of effectiveness (my current hypothesis at least). A simple trick allows you to do this (remember, this is only useful if you don't upload above 1080p). Does higher bitrate affect FPS? If you are concerned about high CPU usage, you have two choices: 1) Buy a higher end CPU with more cores and threads 2) Fiddle with the CPU preset and bitrate If #2 doesn't work, you have to do #1. There is no choice of which GPU - you need an ASIC to be even in a way competitive that does not mean "ok, I heat my house". Full HD resolution is typically 1080p, 60 frames per second (fps). Ensure your encoding CPU / GPU can handle your encoding settings. In the documentation of h.264 (also known as AVC or x.264), the recommended bitrate of H.264 video is as follows: Rendering a video in 1152p and 41 FPS . Assuming your bitrate is set correctly (and you can learn more about bitrates here) NvEnc/AMF is most likely your best option. Report Post. A very high-quality stream is generally 1080p at 60 fps. 1. r/Twitch. Recording - QuickSync/VCE/NVENC 1920x1080p60 50Mbps. Does video bitrate affect FPS? You need to consider few things: First one being your internet upload speed, you can't send the data any faster than your internet speed is, basic rule has been that your bitrate should be max. They do consume more battery than a static wallpaper for sure, but you can't notice it. Its only the newer games killing me. Cap is 6000, be careful going above that. 720p30 and 1080p60. Single-pass encoding has an edge over 2-pass encoding in speed while 2-pass encoding beats the pants off 1-pass encoding in high quality. 720p30 and 1080p60. Video Quality. USB 3.0 unlocks the 80 Hz & 90 Hz modes for . The higher your bitrate, the more bandwidth you will need. It's important to find out if any components are causing issues for you. Playing AAA games in 2021 demands a LOT of your GPU (graphics card) and will use 90-100% of the GPU power when running at full spec. Answer (1 of 4): You don't tell us anything about your planned system, so all anyone can offer is general advice. Higher frame rates and bigger resolutions need more bitrate to keep up with quality, just like working with regular video files. This probably involves doing som. The software encoder (x264) will use your CPU to encode video, while hardware encoders like NVENC will offload the encoding process to your GPU. Having high bitrate settings means you'll need a very stable internet connection. The video bitrate setting determines the amount of data transmitted per second. I have all of my power setting set to maximum performance and I have a 1000 Watt power supply. This feature is CUDA accelerated; toggle this off if your GPU utilization is high to ensure a smooth stream. The GPU Z is a utility that can be used to monitor and test your GPU clock. The RTX cards from NVIDIA use one or more decoders and encoders for encoding and decoding of the graphic content. -Bitrate. 720p 60 fps (HD, high framerate) Psycho Visual Tuning: Checked. it is true amd and nvidia are updating their freesync / gsync standards for HDR to reduce the latency that is caused by tonemapping but that tone mapping was / is happening in the Display . Also that happens when gpu framerate is high (2000-3000 fps) but gpu load is like 50%. For example, if you have such high CPU usage that your PC is slow then there is a setting in OBS called Hardware (NVENC), Hardware (VCE) or Hardware (QSV) within Settings > Output > Streaming. The 8700's TJmax is 105c, so you're well within limits. Yet in the range of visual resolution, when the bit rate is high enough, it doesn't seem to make a difference. You need to ensure that you have enough bandwidth and processing power at each stage to handle the 4K video *at the bandwidth required at that stage*. If you do not, I would think that you either has a graphics card that is not powerful enough or you are running your games in too high settings. IIRC you cannot record at 2 different FPS eg. If your connection can't keep up, your stream will lag, buffer and drop frames to stabilize the stream. So essentially, the bitrate will improve a video's quality, but only to a certain extent. When it comes to video, the closer to the hardware, the better. 3. While the GPU isn't used much if you have just a plain clip with no effects, having a video card is more and more important depending on what GPU-accelerated effects you use in your projects. A new GPU especially since its gen 4 pcie should be more then enough to handle it. 1080p 60 fps (Full HD, high framerate) Recommended upload speed: 6.5-8+ Mbps Resolution: 1920 x 1080 Bitrate: 4500 to 6000 kbps Framerate: 60 fps. Together with a satisfactory bitrate value, high resolution and frame rate contribute to a good-looking video. If you . While you may believe that a higher bitrate will result in better video quality, this is not always the case. Picking the encoder that works best for you depends on a few factors. Encoding and decoding management of the platform. If you give the encoder more "room" to work with it'll be able to store more data, and to do that it'll also require more work. The refresh rate of a monitor is the speed (rate) at which the monitor's image changes (refreshes). A high bitrate is doubtlessly one of the most crucial factors in the quality of a video. But that can be adjusted according to situation and games and etc.. Higher motion game requires higher bitrate. Yet, if you're someone that enjoys single-player titles, like massive open-world RPGs or packed urban cityscapes, then a high resolution may be the best choice for you. So there is not one single best bitrate for streaming with OBS. If you are using only 1 GPU, then set this to 0. Notify Me. Live wallpapers could potentially kill your battery by causing your display to have to light up bright images or by demanding constant action from your phone's processor. Problem with Youtube is that the Bitrate is limited, to achieve better quality a higher bitrate is needed. Figure 15. to get a understanding of the new update what they primarily did is the frames that are being rendered from . Recording - x264 1920x1080p60 Any bitrate. This resolution and high frame rate require a higher bitrate and more encoding power. Generally, high-end graphics cards like RTX 3090, RTX 3080, RTX 2080, and Quadros are ideal for transcoding due to their higher bitrate. It will give you a lot of information about what's going on with the hardware inside your graphics card. Streaming at a higher resolution like 1080p requires a higher bitrate, and a higher frame rate takes more encoding power. In simple terms, video bitrate refers to the amount of video bits/data transferred within a second. You can use this table below as guidance, but if you want to understand more of the nuance and some other key settings, read on below. 1. r/Twitch. CPU encoding is focused on quality where GPU encoding is focused on speed - if you can accept lower quality or higher final bitrate then GPU encoder will be faster, if your goal is highest possible quality at lowest possible bitrate then CPU based encoder will be closer to your goal at a cost of encoding time. GPU-encoding is not a silver-bullet providing only advantages. Hello: While in games, my GPU usage only goes up to approximately 50-60%. If I enable CUVID and set everything to GPU acceleration, I will see no more than 20% CPU load even at high-bitrate 4K. AMD GPUs are also fine to go with, but only if you are concerned with Plex 1080p transcoding. So you know your upload speed and the limits of what it can do what now? Your ideal bitrate is entirely dependant on your internet connection. The more GPU limited the game is, the more of an impact NVENC will have, which is why Forza Horizon 4 is impacted more heavily than the heavy CPU user in Assassin's Creed Odyssey. Actually, this depends. Use your Graphics Card for Encoding. Microsoft Edge has been engineered to optimize for In order to get video quality as high as possible, bitrate . A high bitrate will guarantee that a video running at a high resolution and fps will be smooth, but lower resolution videos will continue to look poor, no matter how high the bitrate is. Link will work over USB 2.0, but only at 72 Hz refresh rate, and trying to increase the bitrate results in stuttering. -FPS. Therefore, the bitrate does have its optimal value. Because when it hit 100% , the game's GPU usage drop bc it got nothing to do ( CPU bottleneck ). I usually only get about 30-50 FPS in games because of this. NVIDIA GeForce Now brings high-quality PC gaming to any PC using the power of the cloud. From video hardware acceleration to PlayReady Content Protection and the Protected Media Path, Windows 10 is designed to provide the highest quality, most secure, and most power-efficient video playback available on any version of Windows. The higher your bitrate, the more bandwidth you will need. Use your Graphics Card for Encoding. Recording - x264 1920x1080p60 Any bitrate. (Yes, SLOBS really IS that GPU intensive, but it is worth it for the user-friendly interface and helpful menus)! HD streams and high bitrate streams take significantly more CPU and GPU resources to capture and encode. So if that's something you're interested in, you should buy a graphics card that will allow you to get high frame rates in your multiplayer titles of choice. I did some testing yesterday and noticed quite a big difference between encoding at 2000 or 4000 kbps. Advanced Media Framework (AMF) is the encoder AMD graphics card users are supposed to use, but there's a bit of a catch. It will generate more heat, but thats where you need to monitor it and put on appropriate cooling apparatus. HDR does require GPU power but also adds ~30ms latency because of the way Windows deals with Tone Mapping. They're more like the digital building blocks of your videos. Also, workstation graphics cards like the ones in the Nvidia Quadro Series yield better results in video transcoding.
