OBS uses the best open source video encoding library available, x264, to encode video. However, some people might experience high CPU utilization, and other programs running on your computer might experience degraded performance while OBS is active if your settings are too high for your computer’s hardware.
What encoder should I use for streaming?
The (New) Nvenc encoder is easily the best OBS encoder available, assuming you have a modern NVIDIA graphics card with the improved ASIC chip. With zero performance impact while encoding and high-quality frames even at low bitrates, it is a strong contender as a streaming encoder.
What encoder should I use for OBS AMD?
If you intend to use OBS and intend to use a hardware encoder to relieve the CPU from encoding, I recommend choosing a Nvidia GPU. Its nvenc encoder is really good and the best among the 3 supported encoders. If you intend to stream, getting a Nvidia GPU for Nvenc is a good investment. Really.
What encoder should I use for OBS Mac?
Output Streaming
This gives us a lot more control and is the only way on Mac to use the hardware encoder. So, for the hardware encoder, I’m using the Apple VT H264 Hardware Encoder. In my 13-inch MacBook Pro, which doesn’t have a discreet GPU, this means OBS is using Intel’s QuickSync encoder built into the CPU.
Should I use NVENC or x264?
x264 uses your CPU to encode video.On faster presets, the CPU spends less time which is less resource intensive, but produces a lower quality image. NVENC is an NVIDIA encoder that uses a dedicated encoder within your GPU to handle all encoding, allowing you to play and stream without compromising game performance.
Which is better x264 or h264?
The benefit of h. 264 is better compression than, say, Mpeg 2, or Mpeg 4 part 2 (Xvid, Divx). “Better compression” means better quality at the same size as those other codecs, smaller size with the same quality, or something in between. x264 is an open source h.
Should I use CPU or GPU for streaming?
If you have a powerful GPU, GPU encoding is better. If you have a powerful CPU, CPU encoding is better. The recommended number of cores for streaming is 6 so if you have 6 cores you can easily stream your game play. If you have the new Nvidia Turing cards I will suggest you use GPU encoding.
How do I make OBS use more CPU?
10 Ways to Fix the OBS CPU Usage too High
- Downscale your output resolution.
- Use your Graphics Card for Encoding.
- Lower Frame Rate.
- Change your x264 preset.
- Check your sources.
- Close Extra Applications.
- Run all audio sources at the same frequency.
- Free Disk Space.
Does OBS use CPU or GPU?
Even if you encode with CPU (x264), OBS needs a minimum amount of GPU power to do the video compositing. A GT 710 isn’t suited for OBS operation at all. You will get rendering lag with it. Even iGPUs might become overloaded, if you compose your scenes with more than 1 or 2 sources.
What is the best encoder for recording?
Best video codec for game, video and screen recording
- Hardware accelerated H.
- Xvid: Best codec for most users.
- MPEG-1: Better compression ratio than Xvid.
- Motion JPEG (MJPEG): Best codec for video editing.
- YV12: Best quality video codec (lossless)
- RGB24: Best quality video codec (lossless)
- External Codec.
What is B frame in OBS?
B-frames (bi-predictive frames) are like extra Keyframes, but instead of showing up consistently they only show as needed. This is done by looking both at the previous frame, and the upcoming frame, and inserting a new frame as needed.
Is OBS optimized for M1?
OBS already has hardware encoder support, and it works great on the M1, even through Rosetta2.
What should I set my keyframe interval be on OBS?
Keyframe Interval:
For live streaming you will want to set your keyframe interval to 2. What this means is that a full video frame will be rendered every 2 seconds. If you want to learn more about keyframes, head over here.
Does Nvenc affect GPU performance?
The game is based on the AnvilNext 2.0 engine from Ubisoft and is characterized by very high CPU and GPU requirements.264 NVENC presets on the gaming performance of Assassin’s Creed Odyssey. As you can see, NVENC has the least impact on performance at 60 FPS output.
What is difference between H264 and H265?
H265, or High Efficient Video Coding, is the new standard video compression that provides even more improvement over H264. H265 provides improved bit reduction of 57% at 1080p and 64% of UHD or 4K compare to H264.Many of the popular streaming website have encoded all their videos to HEVC or H265.
Is h264 good quality?
H. 264 was created to provide high-quality transmission of full-motion video with lower bandwidth requirements and lower latency traditional video standards, such as MPEG-2. H. 264 uses a very efficient codec that provides high-quality images and uses a minimal amount of bandwidth.
Is x264 good quality?
x264 is capable of achieving dramatic performance with encoding four or more 1080p streams in real time on one end-user computer. Compared with other H. 264 encoders, it provides the highest quality with the most advanced psychovisual optimizations available.
Which is better Hevc vs x264?
x264 is the most established open-source software encoder for H. 264/AVC. HEVC is the successor to H. 264/AVC and results reported from standardization showed about 50% bitrate savings for the same quality compared to H.
Is 4 cores enough for streaming?
Most games are optimized to work around a four-core CPU, and it takes about two cores for streaming, so for best results, a machine running an Intel® Core i7 processor or better with at least 8GB of RAM in tow is sufficient for playing games and streaming at the same time.
Why does OBS use so much GPU?
“Why does OBS even need to use the GPU?” OBS needs GPU time and resources because it has to composite and render a scene. If you want OBS to require less resources, you must construct additional pylons you’ll have to build simpler scenes and scene collections.
Is streaming CPU heavy?
Streaming through software encoding is CPU intensive, where streaming through hardware encoding is more GPU intensive. Both streaming options offer benefits and drawbacks depending on the games you plan to stream as well as your computer budget.
