Mastering Filmora performance

Mastering Filmora performance: is a must for video editors. In this guide, I explored tips for troubleshooting common performance issues and optimizing Filmora’s performance to avoid crashes and ensure efficiency. Video editors not using Filmora will find this guide useful for addressing performance issues related to lag and rendering.

Troubleshooting Lag and Rendering Issues

If you have always used a supercomputer you wouldn’t understand the importance of this topic since you have always been on top of issues regarding speed.

Unless that is your case, you are aware of exactly what it is to click a command and wait a thousand years to receive a response from your application.

Not ending there, your application is likely to crash because you send too many commands at the same time as the initial command failed.

Troubleshooting Lag and rendering issues is a topic you need to pay close attention to if you want to enjoy your computer and your applications.

As a video editor, facing the trouble described above will not help you meet your deadline, nor will you be able to produce quality video.

I’ve been through this many times so, I know how it feels and I have tried different solutions to fix this problem.

Let’s look at them.

1. Computer Should Meet System Requirements

Software developers, acknowledging these challenges, furnish users with guidelines specifying the necessary versions of the system software and hardware required to seamlessly operate their software.

You should read this note before buying any software including Wondershare Filmora.

Here are the tech specifications for Wondershare Filmora.

Ensure that your computer meets or exceeds the recommended system requirements for running Filmora. This includes considerations for processor speed, RAM, graphics card, and available storage.

In this article speed up video editing, I looked at what to do to meet the requirements for video editing software. You should read this article when considering professional video editing.

2. Look at the Project Complexity

The complexity of your video project, including the number of tracks, effects, and clips, can impact performance. High-resolution videos or intricate edits may require more processing power.

When this is the case, you may want to separate the scenes among multiple projects and later join the outputs for the final export.

So, before you start importing media files, take into account the complexity of your video project.

3. Pay Attention to Background Processes

Background processes

Check for other resource-intensive applications running in the background. Close unnecessary programs to free up system resources for Filmora.

Some computer users are fond of launching multiple applications at the same time even if they are not in use. This can cause an application’s failure to respond to inputs on time.

In addition, do not install programs you do not need. Reserve your work computer for only essential tools to reduce the workload.

4. Update Outdated Drivers

Ensure that your graphics card drivers are up to date. Outdated drivers can lead to compatibility issues and affect the performance of video editing software.

5. Create a Proxy File

Create proxy file

Enable proxy editing in Filmora to create lower-resolution versions of your media for editing. This reduces the strain on your system, especially when working with high-resolution footage.

The first time I put the Filmora proxy to the test, I was amazed at the result. Enabling a proxy proved to be a game-changer for this sluggish system.

Filmora had a history of frequent crashes on this setup, but with the proxy activated, I experienced seamless functionality with various file types.

To create a proxy file, right-click the clip and click “Create Proxy File” in the menu. After creating the proxy file, you will notice a sign at the left bottom of the clip with a “P.”

Proxy file

Congrats, you have just created a proxy file.

Enabling Filmora Automatic Proxy

1. Go to the “File” menu and select “Preferences.”

2. Click the “Performance” tab.

3. Locate “Proxy” and check the box for “Automatically create proxies when media resolution is higher than:”

4. Set your preferred video and image resolutions.

Leave these default settings. In my case, they are enough.

6. Preview Quality Settings

Adjust the preview quality settings in Filmora. Lowering the preview quality can improve real-time playback performance while editing.

To address any sound delay associated with your video clip, adjusting the preview quality settings can resolve this performance issue.

7. Use the Render Preview

Render parts of your timeline for smoother playback. Use the “Render Preview” option to generate temporary preview files for the selected portions of your project.

8. Export Settings

Optimize export settings based on your project requirements. Choosing the right format, resolution, and bitrate ensures efficient rendering without compromising quality.

9. Utilize Hardware Acceleration

Utilize hardware acceleration if your system supports it. This offloads some processing tasks to your graphics card, enhancing rendering speed.

10. Clear Cache Files

Clearing temporary cache files can free up storage and potentially improve rendering speed.

11. Use SSD for Storage

If possible, use a solid-state drive (SSD) for storing your media files and the software. SSDs offer faster read and write speeds compared to traditional hard drives.

Besides using solid-state drives, you should get a drive with a bigger size that will accommodate more files and also have enough free space.

You can buy solid-state drives on Amazon or the computer shop in your city.

12. Optimize Timeline Structure

Streamline your timeline structure by minimizing unnecessary tracks and effects. This simplifies the editing process and can improve overall performance.

Don’t drag and drop all the files at the same time to your timeline. Load the timeline with the files as needed for your video. Remove any clip or effect you don’t need.

You can always bring them back when you have use for them.

13. Increase RAM Allocation

Random access memory allows the computer to temporarily store and access data immediately. Opting for insufficient memory will result in sluggish performance, especially during multitasking.

If your system has ample RAM, consider increasing the allocated RAM for Filmora in the “preferences”.

This can enhance the software’s ability to handle larger projects.

You can buy RAM on Amazon or any computer shop in your city.

14. Monitor Resource Usage

Use system monitoring tools to track resource usage while editing. Identify any spikes in CPU or memory usage that could be causing performance issues.

You could monitor any software’s performance. In this example, we are looking at Google Chrome.

In Windows 10 you can monitor a program’s resource usage using the task manager. The task manager provides detailed insights into your computer’s performance and resource usage.

Using the Task Manager to Spy on Your System’s Performance

1. Pressing Ctrl+Shift+Esc to open the “Task Manager”.
