How to make blender render a video with sound

Blender is a powerful software for 3D modeling and animation, capable not only of creating stunning 3D models and animations but also rendering high-quality videos and images. When working on animation projects, it's often essential to synchronize sound with visuals to enhance the overall presentation. So, how do you render a video with sound in Blender? This article will guide you through the detailed process.

　　Setting Up the Scene and Animation

　　Firstly, create or import your 3D models and scene in Blender. You can use Blender's array of modeling tools and plugins to create complex geometries and animations. Once your scene and animation are set up, ensure all animation keyframes and camera angles are adjusted accordingly.

　　Importing Audio Files

　　Next, import the audio file you wish to include in your video. In Blender's Video Sequence Editor, you can easily import and edit audio files. Open the Video Sequence Editor, press Shift+A, select "Audio," and then navigate to and choose your desired audio file from your folders.

　　Syncing Audio and Animation

　　After importing the audio file, place it on the timeline and adjust its position to synchronize with your animation. You can preview the synchronization by playing back the timeline. If necessary, adjust the starting point of the audio file or use the cutting tools to remove any unwanted parts.

　　Setting Render Output

　　Once audio and animation are synchronized, proceed to set up the render output. In Blender's Render Properties panel, choose your preferred rendering engine (such as Eevee or Cycles) and adjust the rendering settings accordingly. In the Output Properties panel, select the output format as FFmpeg video because FFmpeg supports exporting audio and video together.

　　Configuring Audio Encoding

　　In the Output Properties panel, after selecting FFmpeg video, scroll down to the audio section. Here, you can choose the appropriate audio encoding format, such as AAC or MP3, and set parameters like bitrate. These settings directly affect the audio quality of the exported video.

　　Rendering the Video

　　Once all settings are configured, press Ctrl+F12 to start rendering the animation. During rendering, Blender will generate the video frame by frame and merge the audio into the video. Depending on the length and complexity of your animation, this process may take some time.

　　Exporting the Video

　　After rendering completes, you can find the generated video file in the designated output folder. At this point, your video includes audio and is ready for playback and sharing. For high-quality 3D textures, HDRI, or 3D model downloads needed for creating models and virtual scenes, you can download them from Relebook and directly import them into your models.

　　Rendering a video with sound in Blender is straightforward when you follow these setup and operation steps. With Blender, you can effortlessly create and export high-quality 3D animated videos while synchronizing audio files, resulting in more engaging and immersive projects.
