Are you struggling to find the best video encoder for OBS on Mac? Choosing the right encoder can drastically impact your streaming and recording experience. OBS is a powerful tool for creators, but the wrong encoder can cause performance issues.
In this post, we’ll break down the options available, explain how video encoding works, and help you select the best video encoder for your OBS Mac setup.
Video encoding is crucial in streaming and recording with OBS on Mac. It converts raw video into a digital format suitable for sharing. The right encoder ensures smooth playback, high video quality, and reduced file size.
Choosing the right video encoder directly impacts performance and visual quality. A poor encoder can cause high CPU usage, lag, and low resolution. The right choice ensures smooth streams and recordings.
"Video encode" refers to the process of compressing video data into a format for storage or transmission. OBS converts video input into a file for efficient streaming and recording, retaining good quality while minimizing file size.
Video encoding compresses data for streaming and storage. Done well, it ensures clear visuals and seamless playback without buffering or stuttering.
A hardware encoder uses dedicated hardware, like a graphics card, for video encoding. Examples are NVIDIA NVENC and Apple VT H264. These encoders offload processing from the CPU, ensuring smoother performance and lower CPU usage.
A software encoder like x264 uses the CPU for encoding. It's more flexible but can consume a lot of power, potentially slowing down your system.
| Type of Encoder | Pros | Cons | Best For |
|---|---|---|---|
| Hardware Encoders | Faster, more efficient, lower CPU usage | May not offer as high quality in some cases | Users with less powerful CPUs, gaming, streaming |
| Software Encoders (x264) | Higher quality video | Heavy on CPU usage, can affect system performance | High-quality recordings, powerful Mac CPUs |
Which one to choose? It depends on your Mac's specs. If you have a powerful CPU, x264 may give better quality. For most Mac users, especially those with less powerful systems, hardware encoders like Apple VT H264 are the best choice.
Apple VT H264 is tailored for Mac users, offering efficient video encoding and reducing CPU load. It’s fully integrated with macOS and OBS, making it an ideal choice for Mac users.
Optimized for macOS, ensuring smooth OBS integration.
Faster encoding with minimal CPU usage.
Reduces lag or stuttering during streaming or recording.
x264 is a software encoder that uses the CPU for video encoding. It offers superior quality but can be CPU-intensive. If your Mac has a powerful CPU, x264 provides excellent video quality with more control over settings.
| Encoder Type | CPU Usage | Video Quality | Ideal Usage |
|---|---|---|---|
| x264 | High | Best video quality | High-quality recordings or streams, if CPU can handle it |
| Apple VT H264 | Low | Excellent for 1080p/720p streams | Mac users needing efficient performance without taxing CPU |
Resolution: Set base and output resolutions to 1080p for smooth streaming. Use 720p for lower-end Macs.
FPS: Set to 30 FPS for most streams, or 60 FPS for fast-paced content like gaming.
Resolution: Choose 1080p for high-quality streams; 720p for lower-performance Macs.
FPS: Use 30 FPS for regular streams, 60 FPS for gaming.
Downscale filter: Use Lanczos for high-quality scaling.
1080p streaming: Set bitrate to 4,500-9,000 kbps.
720p streaming: 2,500-5,000 kbps.
4K streaming: 20,000-50,000 kbps.
Higher bitrates improve video quality, but if you have limited bandwidth or CPU, choose a bitrate that balances quality and system load.
Open OBS Studio on your Mac.
Go to Settings, and click on the Output tab.
Choose your encoder in the Encoder section.
Apple VT H264 is ideal for most users with a decent GPU.
x264 works best if you have a powerful CPU.
Apple VT H264: Set Rate Control to CBR, Bitrate for 1080p to 4,500-9,000 kbps.
x264: Set Rate Control to CBR, Bitrate for 1080p to 6,000-9,000 kbps.
When choosing the right video encoder for OBS on Mac, you’ll encounter three main options: NVIDIA NVENC, Apple VT H264, and x264. Each has unique features, performance benefits, and drawbacks, depending on your system and needs.
Performance: NVENC is a hardware encoder, meaning it offloads the encoding process to your GPU, freeing up your CPU. This results in smoother streaming and recording without overloading your system, which is ideal for gaming and high-intensity tasks.
Quality: While NVENC generally provides good quality, it might not be as sharp as x264 at lower bitrates. It strikes a balance between performance and video quality, making it a great option for real-time streaming.
Compatibility: As NVENC relies on an NVIDIA GPU, it’s unavailable on most Macs, which typically use AMD or integrated graphics. Therefore, this option is more relevant for Windows users.
Performance: Apple VT H264 is designed for macOS and uses the system’s hardware acceleration. This results in low CPU usage and efficient encoding. It’s the go-to choice for Mac users who want smooth performance without taxing the system’s resources.
Quality: The video quality is excellent for most users, providing clear and sharp visuals, especially for 1080p and 720p streams. It offers great quality at a relatively low bitrate, making it perfect for streaming on platforms like YouTube or Twitch.
Compatibility: Apple VT H264 is built specifically for Mac, so it's fully compatible with macOS. It works seamlessly with OBS and doesn't require additional hardware like NVENC.
Performance: x264 is a software encoder, which means it uses your CPU to encode the video. While it delivers fantastic quality, it’s very CPU-intensive. On Macs with powerful processors (like M1 or M2 chips), x264 can produce superior video quality, especially for recording.
Quality: x264 offers excellent video quality, especially at lower bitrates. It’s widely used for high-quality recording, where video sharpness is crucial. However, it can cause lag or performance issues if your CPU can’t keep up with the encoding.
Compatibility: x264 works on all Macs, making it a universal choice for users who want full control over encoding. However, it’s resource-heavy, so be mindful of system limitations.
Gamers: For game streaming, NVIDIA NVENC (if available) is the best choice. It provides high-quality video without overloading the system. Since gaming can be resource-intensive, offloading encoding to the GPU ensures smoother performance.
Vloggers: For vlogging or live-streamed content, Apple VT H264 is the top choice for most Mac users. It offers high-quality encoding with minimal CPU impact, perfect for long streaming sessions without compromising the system’s performance.
Professional Streamers: x264 is ideal for professional streamers who prioritize the highest quality in their streams and recordings. It requires a powerful CPU but offers the sharpest video, which is crucial for high-end production values.
| Encoder | Performance | Quality | Best For |
|---|---|---|---|
| NVIDIA NVENC | Excellent GPU usage | Good, but not as sharp as x264 at low bitrates | Gamers, high-performance streaming |
| Apple VT H264 | Low CPU usage | Excellent for 1080p and 720p streams | Mac streamers, vloggers |
| x264 | CPU-intensive | Highest quality, but heavy on CPU | Professional streamers, high-quality recording |
To achieve the best performance in OBS on Mac, fine-tuning your video encoding settings is crucial:
Choose the Right Encoder: Select a hardware encoder like Apple VT H264 to reduce CPU load. If using x264, adjust the CPU Usage Preset to "Very Fast" or "Fast" for smoother performance.
Set the Right Bitrate: Adjust bitrate based on resolution:
1080p: 4,500 - 9,000 kbps
