Quick and Simple Way to Convert MP4 to Windows Movie Maker

Windows Movie Maker is a beginner-friendly tool for video editing, but it doesn’t support MP4 files due to codec issues. Don’t worry—it’s easy to fix! Converting MP4 files to a compatible format like WMV is simple with the right tools. This guide will show you which formats work, how to convert files, and the best tools to do it quickly and safely.

Why Doesn’t Windows Movie Maker Support MP4?

MP4 is one of the most commonly used video formats due to its versatility and high-quality compression. However, Windows Movie Maker only supports specific formats like WMV (Windows Media Video), AVI, and sometimes MPEG formats.

The issue lies in the codecs used within the MP4 format. If the codecs don’t align with those supported by Windows Movie Maker, the videos simply won’t work. This limitation might feel frustrating at first, but a quick file conversion will solve the problem.

Supported Formats for Windows Movie Maker

Before you start converting your MP4 files, it’s helpful to know which formats work seamlessly with Windows Movie Maker. Stick to these options to ensure compatibility:

• WMV (Windows Media Video): The most reliable format for Windows Movie Maker.
• AVI (Audio Video Interleave): Another supported format commonly used for video editing.
• MPEG (Moving Picture Experts Group): Suitable for exporting or importing less complex projects.

Among these, WMV is often the best choice because it integrates flawlessly with Movie Maker.

How to Convert MP4 for Windows Movie Maker

Now that you know what format you need, here’s how to convert your MP4 files for use in Windows Movie Maker. Follow these simple steps:

Step 1: Choose a Video Conversion Tool

To convert an MP4 file, you’ll need a reliable video converter. Here are some excellent tools you can trust:

• HandBrake (Free): A user-friendly, open-source converter available for both Windows and Mac.
• Any Video Converter: Offers a free and paid version with an intuitive interface.
• Freemake Video Converter: A free tool with advanced features (includes a watermark in the free version).
• Movavi Video Converter: Paid software that’s fast and packed with features.

Download and install the video converter that works best for your needs.

Step 2: Add the MP4 File to Your Converter

Launch your chosen video converter and locate the “Add File” or “Import File” button. Click it to upload your MP4 video to the program. Some converters may allow you to drag and drop the file directly into the application.

When converting multiple MP4 files, batch processing tools can save you time by handling all files simultaneously, streamlining the process and eliminating the need for individual conversions.

Step 3: Select the WMV Format

After loading your file, navigate to the “Output Format” or “Save As” section. Select WMV as your preferred format to ensure full compatibility with Windows Movie Maker and enjoy seamless video editing without any hassle.

You may also have options to adjust the output file’s resolution, bitrate, and frame rate. If your file size isn’t a concern, keep the original quality settings to maintain the best possible video appearance.

Step 4: Start the Conversion Process

Press “Convert” or “Start” to begin. Processing time varies based on your video size and computer performance. Sit back and let the process handle the rest efficiently!

Once the conversion is complete, the tool will save the new file on your computer. Note the location of the file for easy access when importing it into Windows Movie Maker.

Step 5: Import the Converted File into Windows Movie Maker

With the file now in WMV format, you’re ready to add it to your project:

1. Open Windows Movie Maker.
2. Click the “Add videos and photos” button.
3. Locate and select your converted WMV file.
4. Click Open to import it into your timeline.

Your MP4 video is now ready for editing in Windows Movie Maker.

3. Maintain File Organization: Organize your original MP4 files and converted versions in clearly labeled folders to make locating and managing your media files quick, efficient, and hassle-free.

4. Optimize for Size Limits: If your original MP4 file is very large, consider reducing the resolution during conversion to work more efficiently within Movie Maker.
