Streaming Misconceptions - Best OBS Settings & NVENC vs. X264, ft. EposVox _ LTX
# Common Misconceptions in Streaming: A Comprehensive Guide
## Introduction
Welcome back to another episode of our live stream at LTX 2019. We’re here with Adam from "a postbox," a channel known for excellent work in streaming and streaming education. Our topic today is all about common misconceptions regarding streaming settings, and how you might be doing it wrong.
Before diving into the discussion, we’d like to thank our sponsor, Thermal Grizzlies, for their contribution to the conversation. Their innovative thermal interface solutions have significantly improved CPU cooling by enhancing thermal conductivity without sacrificing performance.

## Starting with OBS: Bitrate and Resolution Settings
Let’s begin by assuming a baseline software solution like OBS for streaming. One of the most frequent mistakes we see people making is aiming for the highest possible numbers right away—such as jumping straight into 1080p and 60fps—without considering whether their system can handle it. This is especially true for those streaming from laptops, where performance limitations are more pronounced.
The key takeaway here is that streaming quality isn’t just about resolution or frame rate—it’s about balancing these factors to ensure a stable and high-quality stream. Most people should start by streaming at 720p instead of jumping straight into 1080p, as this will allow you to allocate your bitrate budget more efficiently. Even if you set a high bitrate (like 8 Mbps), it’s unlikely to support a smooth 1080p stream, especially on slower encoders like x264.
Another critical point is the importance of testing. Adam recommends creating a test profile in OBS that mirrors your live stream settings. Record for a few minutes and observe how it performs. If the frame rate drops or artifacts appear, you know it’s time to adjust your settings.

## Frame Rate and Game Performance
When discussing streaming settings, we can’t ignore the importance of frame rates. Many console streamers are unaware that their games run at 30fps by default. Pushing for 60fps might seem tempting, but if your game or webcam can’t handle it, you’re not only wasting resources but also potentially reducing image quality.
For example, if your game runs at 30fps and your webcam is capable of 60fps, it’s better to drop the webcam frame rate to match the game’s performance. This allows for a slower shutter speed, which results in better lighting and overall video quality. Remember, your webcam doesn’t care about frame rates—it cares about how much light it can capture.

## Encoding: CPU vs. GPU
The next major topic is encoding, where we explore both CPU and GPU options. Adam emphasizes that AMD’s encoder, as of now, is in a poor state. While it works for recording at high bitrates, it’s not reliable for streaming due to ongoing issues. If you’re using an older Radeon card (like the X480), expect similar problems.
On the Intel side, Quick Sync is often touted for its performance benefits, but Adam advises avoiding it whenever possible. While it can handle the load, the quality isn’t up to par with other options. NVIDIA’s newer generations, however, are making strides with their GPU encoding capabilities, especially with x264 and VP9 support.
For most streamers, especially those on mid-range systems, sticking with CPU-based encoding using x264 is a safer bet. However, Adam recommends testing your setup thoroughly before going live. Create a test profile in OBS, record for a few minutes, and observe how it performs under real-world conditions.

## Common Misconceptions: Quality vs. Quantity
One of the most persistent myths in streaming is that GPU encoding always produces lower quality output. While this might have been true in the past, NVIDIA’s fine-tuned optimizations for game streaming are starting to change the narrative._GPU encoders are designed with a specific purpose in mind: handling game streams._ This means they can often outperform CPU-based alternatives when it comes to gaming content.
Another misconception is that higher resolution or frame rate always equates to better quality. While 1080p and 60fps might sound impressive, they’re not the right choice for everyone. Adam suggests starting at 720p and adjusting from there based on your system’s capabilities. Your audience won’t notice a difference in resolution if the stream is stable and high-quality.

## Webcam Settings: Getting the Best Image Quality
Finally, let’s talk about webcams—a critical component of any streaming setup. Many people assume that their webcam can handle 1080p natively, but this isn’t always the case. In reality, most entry-level webcams (like the C920) produce the best image quality at lower resolutions like 640x360. Shooting for a quarter of your screen might not look as impressive on paper, but it will ensure better perceived quality during live streams.

## Final Tips
- **Test Everything**: Before going live, test your settings thoroughly. Use OBS to create a test profile and record a short clip. If you notice any issues like dropped frames or artifacts, adjust your settings accordingly.
- **Focus on Audio Quality**: Many streamers overlook the importance of audio quality. Invest in a decent microphone and use a separate audio interface if possible.
- **Use a Second Twitch Account**: If you’re hesitant to test new software or settings on your main account, consider streaming on a secondary account first. This allows you to experiment without risking your hard-earned reputation.

## Conclusion
In conclusion, streaming is all about balancing bitrate, resolution, and frame rate to achieve the best possible quality within your system’s constraints. Avoid chasing higher numbers like 1080p or 60fps if they don’t work for you. Instead, start with 720p and adjust from there based on testing.
