While the software is surely great at what it does, sometimes minor issues in encoder settings can cause problems and make it impossible to do the work. In the case of OBS Studio, ‘failed to open NVENC codec’ errors and many more have been frequently reported by its users. 

However, this software is backed up by NVIDIA Encoder and uses the feature to do most of its work. If you’re unfortunate enough to encounter an NVENC error, you need to implement changes to your system ASAP, or you won’t display this or other websites correctly.

How to Solve OBS Studio NVENC Errors?

Addressing the reasons for these errors, we can now discuss the solutions to the NVENC error OBS. The solutions mentioned below have been highly helpful to people who have encountered OBS NVENC issues on their computers. 

While reading, make sure to understand each method and apply it the right way:

1. Update Your Graphic Drivers

When you see Nvidia NVENC errors, your first choice of action should always be to update your graphic drivers. Most of these errors are caused by outdated drivers, as OBS requires only the most up-to-date version of the GPU drivers. Make sure to go through encoder settings, to eliminate the possibility of any error.  

Usually, an upgrade or use an alternative browser fixes the OVS NVENC error on your device. However, if you’re unlucky, it only means the issue was not the outdated GPU drivers. If this is the case, try the method given below. 

2. Restart Your PC

Restarting your PC can solve almost all of your problems. In the case of an error, restarting your computer will reset and stop all programs, including streaming and recording, allowing you to start fresh. 

Doing this, you probably won’t see any OBS errors.

3. Lower Your Resolution

It is possible that your device can’t handle high-resolution tasks. Make sure to reduce your resolution if you believe that it is the reason why the OBS error occurred. OBS Studio can easily handle 4K resolution; anything above that requires a high-end PC on the other side.

Lowering your resolution will greatly decrease the burden on your device and OBS Studio while running operations. 

4. Enable QuickSync

In case of Nvidia NVENC errors, something that you can do is switch to QuickSync, as it is better than Nvidia at handling encoding tasks. 

Here is how you can enable QuickSync on OBS Studio:

  1. Start OBS Studio, click on File, and then go to Settings.
  2. Click on the Output tab.
  3. Select QuickSync H.264.
  4. Now save your changes.

This switch will surely help you solve errors like failing to open the NVEC codec and it may also fix output scaled resolution. 

5. Close Multiple Sessions

A lot of times, there is no issue with either the device or OBS Studio; instead, the problem is caused because multiple sessions are running at a time. How many concurrent sessions you can run on OBS Studio directly depends on your PC and GPU drivers’ collective strength. 

If you’re encountering errors like ‘Function not implemented’ or ‘Fail to open NVENC Codec,’ you should close multiple sessions and run only one at a time. 

6. Close Background Applications

Similar to running multiple sessions, you should also be careful about how many applications and streaming and recording software are running in the background, as it can cause errors with your OBS. 

If you’re running a game in the background or any other software that demands a lot of resources from the CPU/GPU, it is advised that you close it. Doing this will greatly reduce the load on your device and allow it to focus solely on running OBS Studio. 

That’s all you need to know about OBS NVENC errors and how you can fix them on your computer. If you’re going through OBS Studio errors, make sure that you have followed the fixes we have given in the last section. Applying these will help you keep your system up to date with OBS and also use it efficiently.
