Step 1. Open Filmora and access the Audio-to-Video feature

If you haven't already, download the latest version of Filmora and install it on your device. Once installed, open the program, and on the home screen, click on the “Audio-to-Video” option right below “New Project".

Step 2. Upload your audio file

Now it’s time to add your audio. Click the Filmora logo to upload a file from your device, or paste a YouTube link (you’ll need to log in to your account first). Just remember: your audio should be between 10 to 120 minutes long and under 1 GB in size.

Step 3. Customize your settings

Before generating the video, tweak a few settings to fit your needs. Start by selecting your audio’s language, then decide the type of video you want to create. Then, adjust the “Ratio” and “Duration” for your video. You can also choose a "Picture Style" or upload your own image for a personal touch.

If you are looking for a quicker setup, you can browse through Filmora’s templates and choose one that fits your style. Once everything is ready, click “Generate” and let Filmora do its thing—it only takes a few minutes!

Step 4. Preview and select your video

When your video is ready, you’ll be presented with 1-3 video options, each with a rating. Click the play button to preview the results. If you’re happy with the outcome, you can export the video immediately. If you’d like to make additional edits, simply click "Edit", and you’ll be taken to Filmora’s main editing timeline.

Step 5. Edit your video

In the main timeline, you can switch between Select mode and Duration Filter mode to view the script. Select mode lets you show or hide specific sections of the script based on your needs, while Duration Filter mode helps you sort and filter content according to its timecode.

When you click on the script or text in the preview window, the property panel will appear. Navigate to the "Template" option to customize and modify the dynamic captions. Pick the template you like, and click "Apply to All" to apply it across all captions in your project.

To edit the script, open the Text > Basic tab in the property panel. From there, you can modify the script, emphasize specific words by highlighting them, or merge them to create a more seamless flow.

Enhance your video by adding filters to give it a polished look. Go to the “Filter” tab, select your favorite options, and apply them to your video. You can then use the property panel to adjust the intensity or refine the filter settings for optimal results.

You can also make your video even more viewer-friendly by adding subtitles, including translations. Filmora’s Text-to-Speech feature makes it a breeze. For more details, check out Filmora’s official guide on how it works: Filmora’s Text-to-Speech Official Guide.

Step 5. Export and share your video

When your video is ready, click “Export” in the top-right corner. To share it directly on social media, select the “Social Media” option. If you’d rather save it to your device, choose “Local” and adjust details like the title, description, category, and resolution.
