Mastering all the video editing tricks you can use to improve the quality of the videos you create in Filmora takes time and practice. Even though learning different video editing techniques is a time-consuming task, improving video editing performance in Filmora is a routine job. Here are a few tips and tricks you can use to ensure fast and efficient workflow in Filmora.

Secret 1: Activate the GPU Acceleration option

Computer components like the processor or the graphics card determine how smooth the playback of your videos is going to be. In case the computer you are using to edit your footage doesn’t have an Intel i3 processor of the latest generation, you should enable Filmora’s hardware acceleration mode that reduces lagging during video playback to the minimum.

How to enable GPU Acceleration in Filmora?

After you create a new project, you should click on the File menu and select the Preferences option. Alternatively, you can use the Ctrl+Shift+, keyboard shortcut to bring up the Preferences window.

Afterward, you should click on the Performance tab, and then make sure that the checkbox next to the Enable Hardware Acceleration for video rendering and playback is marked.

Below this option, you will also see the Enable Hardware Acceleration for video decoding setting, so just click on the checkbox next to it to activate it. These two features speed up the video rendering process, reduce the amount of time Filmora needs to decode a video and ensure smooth playback of high-resolution video files.

After you checked these two checkboxes, you should click on the OK button at the bottom of the Preferences window and proceed to restart Filmora to complete the process of enabling GPU Acceleration.

What is GPU, and Why GPU acceleration is important in video editing?

Graphics Processing Unit or GPU is a programmable logic processor that is specialized for display functions. Most inexperienced video editors fail to understand how important a graphics card is during the video editing process since it is a widely accepted opinion that CPU does all the heavy lifting.

While this is true to some degree, GPU is vital on projects that involve editing of 2K and 4K footage, as video editing software utilizes GPU to achieve better video playback performances.

GPU Acceleration is a technique that allows a computer’s GPU to reduce the strain that demanding video editing applications put on CPU and improves the speed and efficiency of these applications. The GPU Acceleration technique is frequently used in video editing, as it reduces the amount of time that is required to render high-resolution footage. That is why it is so important to add a powerful GPU to your computer’s CPU if you are planning to edit 2K or 4K videos in Filmora frequently.

Secret 2: Adjust the playback quality of video clips

Even though Filmora allows you to set the resolutions of your projects to 4K and manipulate the videos captured in these resolutions, its preview window can’t display all the information these files contain. Reducing the quality of the videos shown in the preview window makes their playback smoother and increases your efficiency during the video editing process.

How to Change Playback Quality in Filmora?

Altering the playback quality of a video clip in Filmora is simple since you just need to click on the Preview quality and display settings icon located below the preview window. After you click on this icon that looks like a computer monitor, you should expand the Playback Quality menu.

Change Filmora Playback Settings

The Full option is going to be selected by default, which means that Filmora displays all video clips you place on the timeline in their full resolutions. So, if you are editing the 1080p footage, the editor is going to display the videos in 1920x1080 resolution.

Selecting ½ option from the Playback Quality menu will reduce the resolution in which videos are displayed by half, and the image you will see on the screen is going to be in 960x540 resolution. Selecting the ¼ option will bring down the resolution of a 1080p video to 480x270 pixels, while the 1/8 option shrinks the resolution of that video clip to 240x135 pixels.

Choosing the 1/16 option from the Playback Quality menu can be useful if you are working with DCI 4K footage and you want to reduce their resolution from 4096x2160 to 256x136 pixels.

These changes only affect the resolution of the videos displayed in Filmora’s preview window and they do not impact the resolution of the video file you export from the editor.

Secret 3: Create Render Previews

Applying transitions or visual effects to a video clip can produce lagging during playback or freeze the clip entirely. The Render Preview option resolves this issue by creating previews of frames in a video and ensuring a smooth playback.

In case you are experiencing such difficulties you should select a video clip and click on the Render Preview icon located on the right side of Filmora’s toolbar. Optionally you can choose a clip to which you applied a transition or a visual effect and press Enter on your keyboard to start creating render previews.

Filmora can also create render previews automatically when no other action is performed for a specified duration of time. By default, Filmora is going to wait for five seconds before it starts to generate render previews.

 Filmora Auto Preview Render Settings

Use the Ctrl+Shift+, keyboard shortcut to gain access to the Preferences window, and then click on the Performance tab. Click on the Background Render checkbox that is located directly below the Preview Render option and proceed to specify the amount of time after which the background renders should start. You can also choose the folder in which preview render files are going to be stored or decide to delete all preview render files every time you close a project.

Secret 4: Generate Proxy Files

One of the most common ways to ensure that high-resolution video files are going to be displayed without lagging is to create proxy files. After you add a video clip to Filmora’s Media Panel, you should right-click on it and select the Create Proxy file option.

Right Click to create Proxy files

The software will then create a low-resolution proxy that won’t slow down your workflow, although how long this process is going to take depends on the size of the original video file.

Generating proxies may be a lengthy process depending on your original video, which is why it is essential to go through it before you perform any other video editing task.

The created low-quality proxy file is used for improving the smoothness of the editing process only. Proxies do not affect the quality of the source footage nor the exported video. So once you complete editing, you can export it the same way you would export a project if you were working with original video files.

Secret 5: Shared Media Folder

If you have a YouTube channel, you may need to use some same intro or outro frames in your YouTube video. It’s annoying if you have imported them every time you create a video project. While, the Shared Media feature in Filmora can store video and audio that you've imported for future projects, which means that you don't have to keep re-importing your media for future videos. Here is how to use the Shared Media folder in Filmora to improve the video editing efficiency.

Go to the media panel, click the Share Media folder, then click Import Media or drag and drop your footage or audio you want to use for future projects. you can also create new folders in the Share Media folder to help you organize your media files.

Secret 6: Copy and Paste Effects

Sometimes you may need to add the same effects to another clip in the video project. Previously, you may need to add effects to each clip one by one, but now, Filmora allows you to copy and paste effects from one clip to another directly.

Once you're done adding effects to one clip, right click and click Copy Effects; then select the clip you want to paste the effect to, right click the clip and click Paste Effect.

Secret 7: Mark Clip with Color Marks and Group

When editing footage from multiple cameras, you might want to organize which media is from which source in the timeline. Or, you want to recognize certain scenes from multiple clips, you can use the color marks in Filmora to do that.

Select the clips you want to color mark in the timeline, right click and then choose from the colors available. Repeat the steps to color mark other clips. Once you've color-marked all your clips, you can right-click on the clip again and click Select all clips from the same color mark option, and all the clips

marked with that color will be selected, so you can move a lot of clips at once in the timeline.

You can group all the clips with the same color marks together so you can sync the video and audio. Or, you can select all clips you want to group, right click and then select Group to group clips together without marking color.
