Adobe Premiere Pro vs After Effects: Which one should you use?

Premiere Pro is one of the most popular video editing programs in the world and part of Adobe’s famed Creative Cloud suite of productivity and design programs. However, as much effort as Adobe has put into its video editor to make the program easy to use, it still is notorious for random bugs and glitches from time to time. 

In this article, we’re talking about the accelerated renderer error in Premiere Pro, its causes and what you can do to fix the problem.


What causes accelerated renderer error?

The error can be triggered by a number of issues. Some of the most common causes include:

  • Hardware compatibility issues.
  • Outdated Premiere Pro version. 
  • Outdated GPU driver.
  • Corrupt source media files or media cache.
  • Incompatible video codec/format.
  • H.264 and HVEC decoder issues.

Here are seven fixes you can try out. 

Restart your computer

Restarting your computer can often be the simplest solution when dealing with such errors. Rebooting your machine often fixes seemingly random issues, especially when dealing with hardware issues. 


Update your GPU drivers 

Outdated GPU drivers can also cause this issue in particular. While you should update all your drivers, take special care of your display drivers if you run into an error like this. 

Step 1: Right-click Start and select Device Manager from the menu.

Change the Premiere renderer

Changing the Premiere render engine to software only can also help resolve the error. Here’s how. 

Step 1: Open Premiere, click on Edit, followed by Preferences and then Media. 

Step 2: Uncheck any hardware encoding options. 

Restart Premiere and the error should be gone. 


Clear the media cache

A corrupt media cache is the cause of a lot of different headaches in the program. Try clearing it to see if that makes a difference. 

Step 1: Open Premiere Pro and head over to Edit, followed by Preferences and then Media Cache.

Check the video format and codec

Check and see if the video format and codec that you’re trying to support are actually supported. You can refer to this page for a list of all supported video formats and codecs.

If the video you’re trying to import isn’t compatible with Premiere, you’re going to have to convert it into another format. We recommend using MP4 with H264 encoding as that’s the most hassle-free format and codec in Premiere. 


Update Premiere

Updating Premiere might also fix your issue. You can do this from the Creative Cloud dashboard by checking for any available updates. If there are any updates available, install them right away and restart Premiere to see if that fixes the problem. 


Reinstall Premiere

Try reinstalling the software from scratch to fix your issues if nothing else works. Reinstalling Premiere is also rather easy, although we recommend you do it from the Creative Cloud panel and not through Windows settings.

All you have to do is open Creative Cloud. head over to All Apps and you’ll see Premiere listed below. Click the three horizontal dots next to it and select Uninstall. Once the uninstallation is complete, you can use the Creative Cloud panel to install Premiere again and hopefully resolve any issues you’re facing.
