Configure OBS Dynamic Bitrate for Network Throttling

This article explains how to configure OBS Studio to handle severe network throttling during live streams. While streaming protocols (like RTMP) do not allow you to change your actual output resolution (e.g., 1080p to 720p) mid-stream without disconnecting, OBS Studio offers a powerful “Dynamic Bitrate” feature. This setting automatically lowers your stream’s bitrate and quality to match your available bandwidth during network instability, preventing dropped frames and stream lag.

Why You Can’t Dynamically Change Resolution Mid-Stream

Standard live streaming protocols require a fixed video resolution from the moment the stream starts. Attempting to change the physical resolution scale while live would force the encoder to reset, causing your stream to disconnect and restart. To solve this, OBS Studio adjusts the bitrate instead. Lowering the bitrate reduces the data load on your network, preserving stream continuity at the cost of temporary image compression, which functions effectively as a dynamic quality drop.

How to Enable Dynamic Bitrate in OBS Studio

To configure OBS to automatically manage network congestion, follow these steps:

  1. Open OBS Studio and click on Settings in the bottom-right Controls dock (or go to File > Settings).
  2. In the left-hand menu, click on the Advanced tab.
  3. Scroll down to the Network section.
  4. Check the box next to Dynamically change bitrate to manage congestion.
  5. (Optional) Check the box for Enable network optimizations to utilize OBS’s updated network pipeline, which improves throughput handling.
  6. Click Apply and then OK to save your changes.

What Happens During Network Throttling

Once this feature is enabled, OBS Studio will actively monitor your connection to the streaming server (e.g., Twitch, YouTube, or Kick).
