After Effects is an incredibly powerful tool for video editing and motion graphics, but like any complex software, it can sometimes slow down or become unresponsive due to cache buildup. When this happens, it’s essential to know how to manually clear the cache to get your workflow back on track. In this article, we’ll explore the reasons why cache clearing is necessary, and provide a detailed, step-by-step guide on how to manually clear cache in After Effects.
Why Do I Need to Clear Cache in After Effects?
Before we dive into the how-to, let’s take a quick look at why clearing cache is essential in After Effects. The cache is a temporary storage area where After Effects stores data and resources to improve performance. However, over time, this cache can become bloated, leading to:
- Slow performance and lag
- Unnecessary memory usage
- Crashes and freezes
- Inaccurate renders and previews
- Increased disk space usage
When you clear the cache, you’re essentially resetting the software to its default state, freeing up resources and allowing After Effects to function smoothly again.
Understanding the Different Types of Cache in After Effects
Before we proceed with the manual cache clearing process, it’s essential to understand the different types of cache in After Effects. There are three main types:
Disk Cache
The Disk Cache stores rendered frames and previews on your hard drive. This cache helps speed up the rendering process by reusing previously rendered frames. However, it can quickly grow in size, taking up valuable disk space.
RAM Cache
The RAM Cache stores temporary data and resources in your system’s RAM. This cache is used to improve performance by providing quick access to frequently used data. However, if your RAM is limited, the RAM Cache can cause performance issues.
GPU Cache
The GPU Cache stores rendered frames and graphics on your graphics card. This cache is used to improve rendering performance by offloading graphics processing from your CPU to your GPU.
Manually Clearing Cache in After Effects
Now that we’ve covered the basics, let’s dive into the step-by-step process of manually clearing cache in After Effects.

Alternatively, you can also clear the RAM Cache by restarting After Effects. This will automatically clear the RAM Cache.
Clearing the GPU Cache
To clear the GPU Cache, follow these steps:
- Go to Edit > Preferences > GPU.
- In the GPU Preferences dialog box, select the Reset GPU Cache option.
- Click OK to confirm.
Alternatively, you can also clear the GPU Cache by restarting your computer. This will automatically clear the GPU Cache.
Tips and Tricks for Managing Cache in After Effects
While manually clearing cache is essential, there are some additional tips and tricks to help you manage cache more effectively in After Effects:
Set a Cache Limit
You can set a cache limit in After Effects to prevent the cache from growing too large. To do this, go to Edit > Preferences > Media & Disk Cache, and set the Disk Cache Size to a desired value.
Use a Cache-Friendly Workflow
A cache-friendly workflow involves working on smaller projects, using lower resolutions, and avoiding complex compositions. This can help reduce cache buildup and improve performance.
Regularly Clear Cache
Regularly clearing the cache can help prevent performance issues and free up disk space. Try to clear the cache at least once a week, or whenever you notice a significant slowdown.
Consider Upgrading Your Hardware
If you’re experiencing frequent cache-related issues, it may be time to consider upgrading your hardware. Adding more RAM, replacing your hard drive with a faster SSD, or upgrading your GPU can significantly improve performance and reduce cache buildup.
Conclusion
Clearing cache in After Effects is a relatively simple process, but it can make a significant difference in performance and workflow. By understanding the different types of cache and manually clearing them regularly, you can ensure that After Effects runs smoothly and efficiently. Remember to set a cache limit, use a cache-friendly workflow, regularly clear cache, and consider upgrading your hardware for optimal performance. With these tips and tricks, you’ll be well on your way to becoming a cache-clearing master in After Effects!
What is cache in After Effects and why do I need to clear it?
Cache in After Effects refers to the temporary files and data that the program stores on your computer to speed up performance. These files can take up a significant amount of space on your hard drive and can slow down your computer over time. Clearing the cache is necessary to free up disk space, improve performance, and prevent errors.
Clearing the cache also helps to remove any corrupted or outdated data that may be causing issues with your project. By clearing the cache, you can start with a fresh slate and ensure that After Effects is running smoothly. Additionally, clearing the cache can help to prevent crashes and errors, allowing you to work more efficiently and effectively.
How often should I clear the cache in After Effects?
It’s a good idea to clear the cache in After Effects regularly, especially if you’re working on large or complex projects. You may want to clear the cache daily or weekly, depending on how frequently you use the program. If you notice that your project is taking a long time to render or that you’re experiencing performance issues, clearing the cache can help to resolve these issues.
You may also want to clear the cache after making significant changes to your project, such as adding new footage or effects. This can help to ensure that After Effects is using the most up-to-date data and can help to prevent errors.
What happens if I don’t clear the cache in After Effects?
If you don’t clear the cache in After Effects, you may start to notice performance issues, such as slow rendering times or crashes. This is because the cache can become bloated and filled with outdated or corrupted data. Over time, this can cause problems with your project, such as errors or unexpected behavior.
In extreme cases, a bloated cache can even cause your computer to run out of disk space, leading to more serious problems. By clearing the cache regularly, you can avoid these issues and ensure that After Effects is running smoothly.
Will clearing the cache delete any of my project files?
No, clearing the cache in After Effects will not delete any of your project files. The cache is a separate set of files that are used by the program to speed up performance, and clearing it will not affect your actual project files.
You can clear the cache with confidence, knowing that your project files will remain intact. In fact, clearing the cache can actually help to ensure that your project files are safe and secure, as it removes any potential corrupted data that could cause problems.
Can I clear the cache automatically in After Effects?
No, After Effects does not have an automatic cache clearing feature. However, you can set the program to clear the cache every time you close it. To do this, go to Edit > Preferences > Media & Disk Cache, and check the box next to “Delete cache files when After Effects is quit.”
While this can be a convenient option, it’s still a good idea to manually clear the cache from time to time to ensure that it’s completely cleared out.
How long does it take to clear the cache in After Effects?
The time it takes to clear the cache in After Effects will depend on the size of the cache and the speed of your computer. Typically, clearing the cache only takes a few minutes, but it can take longer if you have a very large cache.
