Reasons to Recommend Simultaneous Streaming on Twitch and YouTube Using OBS

Here are the reasons why we recommend simultaneous streaming on Twitch and YouTube using OBS:

  • Expand your audience reach
  • Store archives for an extended period
  • Reduce streaming risks

Let’s delve into each point.

Expand Your Audience Reach

The major appeal of multi-streaming on Twitch and YouTube using OBS is the ability to reach different audience demographics.

Twitch is renowned for its gaming-centric community, bringing together game enthusiasts. On the other hand, YouTube boasts a broader range of content, attracting diverse viewer demographics.

By engaging in simultaneous streaming, you can simultaneously tap into the distinct user bases of both platforms, enhancing brand recognition and potentially acquiring new fans.

Moreover, using multiple platforms might lead one platform’s viewers to discover and engage with your content on another platform.

Store Archives for an Extended Period

A downside of Twitch is its limited archive retention period, leading to automatic deletion after a set duration.

Conversely, with YouTube, content can remain accessible indefinitely as videos post-stream, allowing viewers to revisit past content.

This is a significant advantage for those aiming for long-term audience growth. Streaming on both platforms enables you to extend the lifespan of your content.

Reduce Streaming Risks

Even if one platform encounters server issues or undergoes maintenance, streaming can potentially continue on the other platform.

This ensures that viewers can continue enjoying content uninterrupted, a major benefit. Furthermore, simultaneous streaming offers a risk distribution strategy if your streaming setup becomes unstable, as viewers can seamlessly switch between platforms during disruptions.

Is Simultaneous Streaming on Twitch and YouTube with OBS Prohibited? Is It a Violation?

Previously, simultaneous streaming on Twitch and YouTube using OBS was against Twitch’s terms of service. Particularly, partners and affiliates had an exclusivity obligation, making it a breach of regulations.

However, with the policy revision in October 2023, simultaneous streaming on Twitch and YouTube is now officially allowed. Consequently, you can broaden your audience base across multiple platforms.

When streaming, make sure to check the latest guidelines of each platform and adhere to the rules for responsible streaming.

Points to Consider When Simultaneous Streaming on Twitch Using OBS

Here are important considerations for simultaneous streaming on Twitch using OBS:

  • Do not redirect viewers to other platforms
  • Ensure the same or superior streaming quality on Twitch
  • Avoid combining chats from other platforms

Let’s explore each point in detail.

Do Not Redirect Viewers to Other Platforms

When simultaneous streaming on Twitch, redirecting viewers, such as saying “I’m also streaming on YouTube”, is a violation of the platform’s terms, so caution is required.

Sharing links or directly guiding viewers to other streaming destinations is strictly prohibited under Twitch’s guidelines.

Violations of this rule may result in penalties to your account. It’s crucial to offer an independent viewing experience on each platform, respecting both sets of rules.

Ensure the Same or Superior Streaming Quality on Twitch

When simultaneously streaming on Twitch, it’s imperative to offer quality equal to or greater than other platforms. Optimize settings for video and audio to deliver a satisfying viewer experience.

Specifically, adjusting the streaming bitrate and resolution is essential for providing smooth and high-quality visuals. Engaging in real-time comment interaction is also important for fostering viewer communication.

By understanding Twitch’s unique characteristics and audience demographics, you can aim for distinctive streaming that stands out from other platforms.

Avoid Combining Chats from Other Platforms

Combining chats from multiple platforms like Twitch and YouTube in the display for viewers is against Twitch’s terms and should be avoided.

Each platform places a premium on its unique user experience, and directly sharing elements from other platforms is prohibited.

For example, using tools like OBS to display YouTube chat over a Twitch stream is not allowed.

When multi-streaming, it’s crucial to maintain independent viewing experiences for each platform. Ensure compliance with rules while effectively communicating with viewers.

Reasons for Load During Simultaneous Streaming and Their Solutions

While convenient, simultaneous streaming with OBS may lead to PC or internet issues due to load, resulting in screen loss or interruptions stemming from misconfigurations or environmental problems.

Let’s explore the causes of load and screen loss during simultaneous streaming with OBS, along with solutions:

  • Insufficient PC specifications
  • Insufficient network bandwidth
  • OBS configuration errors

Let’s examine each with its solutions.

Insufficient PC Specifications

Simultaneous streaming places a high demand on CPU and GPU, and if the PC’s performance is insufficient, you may encounter slow operation or screen loss. Particularly, encoding processes or high-resolution video output may be the culprits.

A practical solution is altering OBS’s encoding settings to “hardware encoding” to alleviate CPU load. Additionally, lowering resolution or framerate reduces the overall processing burden.

If feasible, acquire a high-performance PC to solidify an environment capable of stable multi-streaming.

Insufficient Network Bandwidth

Given the large volume of data transmission required during simultaneous streaming, inadequate network speed or stability can disrupt streams. Especially with excessive bitrates, bandwidth constraints may cause video delays or screen loss.

Mitigation involves lowering the streaming bitrate appropriately to lessen network load. Switching from wireless to wired connections can also ensure more stable communications.

Consider introducing high-speed internet to withstand heavy data exchange requirements.

OBS Configuration Errors

Incorrect OBS source settings or conflicting plugins can result in screen loss or missing audio during streams.

Effective remedies include verifying each source individually, deleting unnecessary plugins, and updating OBS to the latest version.

Conduct a test stream before going live to check for dropped frames or encoding issues using OBS’s statistics to preempt troubleshooting.
