How to render mp4 in blender without render preview

Rendering video files in Blender is a common need for animation and video editing. Often, you may want to directly output a high-quality MP4 file without using the render preview. This method can save time while ensuring the quality of the output file. This guide will walk you through how to render MP4 files in Blender without using render preview.

Preparation

Before you begin rendering, make sure your Blender project is complete and ready for rendering. Here are some preparatory steps:

1. Check Animation Settings:

- Ensure that your animation settings are correct, including frame rate, start and end frames, and keyframe timings. You can adjust these settings in the "Render Properties" panel.

- Verify that all materials, lighting, and camera settings are in place. This ensures that the rendered result will meet your expectations.

2. Configure Render Settings:

- In Blender's "Render Properties" panel, choose the appropriate render engine (such as Cycles or Eevee). Different render engines suit different needs—Cycles is better for high-quality renders, while Eevee is more suited for real-time rendering.

- Make sure that you have selected "File Output" as "FFmpeg video" to output the video in MP4 format.

Configuring MP4 Output

To render an MP4 file in Blender, follow these settings:

1. Set Output Format:

- In the "Output Properties" panel, find the "File Format" option and choose "FFmpeg video." This will allow you to output the render as an MP4 video file.

- In the "Encoding" section, select the appropriate encoder (such as H.264) and set the video quality. H.264 is a widely used video encoding format suitable for MP4 file output.

2. Adjust Video Encoding Settings:

- In the "Encoding" section, you can choose the bitrate settings. A higher bitrate generally provides better video quality but increases file size. Choose a suitable bitrate based on your needs.

- If your video contains audio, configure the audio encoding settings to match your video's content.

3. Select Output Path:

- In the "Output" section, set the folder path and filename where you want to save the rendered result. Ensure the path is valid to avoid errors during rendering.

Start Rendering

Once all settings are complete, you can begin the rendering process:

1. Start Rendering:

- After confirming all settings are correct, click the "Render" button, then select "Render Animation." Blender will render according to the start and end frames you’ve set and save the result as an MP4 file.

- Rendering may take some time depending on the complexity of your animation and your computer's performance. You can monitor the rendering progress in Blender’s "Render" panel.

2. Check Render Result:

- After rendering is complete, navigate to the output path you set and check the generated MP4 file. Play the file to ensure the rendered result meets your expectations and there are no issues.

Avoiding Render Preview: Important Considerations

When rendering MP4 in Blender without using render preview, keep the following in mind:

1. Accuracy of Render Settings:

- Ensure that all render settings are accurate to avoid discrepancies between the rendered result and your expectations. Pay special attention when selecting the encoder and bitrate to match your video quality requirements.

2. Resource Usage:

- Rendering MP4 files typically requires significant computational resources, especially with high resolution and quality settings. Ensure your computer has adequate processing power to prevent delays or interruptions during rendering.

3. Save Regularly:

- It’s advisable to save your Blender project file regularly during rendering to prevent data loss in case of unexpected issues.

Rendering MP4 files in Blender without using render preview can significantly improve efficiency, especially for complex animations and lengthy rendering tasks. By correctly configuring output settings and encoding parameters, you can achieve high-quality MP4 files and bypass the need for render preview.
