Converting projects created in Windows Movie Maker to MP4 format is essential for wider compatibility and easier sharing. This process involves using a converter to transcode the Movie Maker project (.wlmp) or the exported Windows Media Video (.wmv) file into the widely supported MP4 (.mp4) format.
Understanding the Need for Conversion
Windows Movie Maker, once a staple on Windows operating systems, saves projects in a proprietary format (.wlmp). This format, while useful for editing within the software, is not readily playable or editable in other programs. Furthermore, Movie Maker typically exports videos as Windows Media Video (.wmv) files. While WMV is compatible with Windows, it is less universally supported than MP4. MP4 is a more versatile format playable on a wider range of devices (smartphones, tablets, computers, smart TVs) and compatible with various video editing software. Converting to MP4 allows for easier sharing on platforms like YouTube, Vimeo, and social media.
Methods for Converting Movie Maker Projects to MP4
There are essentially two scenarios: converting a .wlmp project file and converting a .wmv video file already exported from Movie Maker.
Converting the .wmv Output
This is the most common and reliable method. First, export your project from Movie Maker as a .wmv file. Navigate to “File” > “Save Movie” and choose a suitable quality setting (e.g., “For computer” or “For email” if you want a smaller file size). This creates a .wmv video file on your computer.
Once you have the .wmv file, you can use several conversion methods:
-
Using Dedicated Video Converter Software: Numerous video converter programs are available, both free and paid. Popular options include HandBrake (free and open-source), Freemake Video Converter (free), Any Video Converter (paid with a free trial), and Wondershare UniConverter (paid). These programs offer a user-friendly interface for selecting your .wmv file, choosing MP4 as the output format, and adjusting encoding settings (resolution, bitrate, frame rate).
-
Online Video Converters: Several websites offer free online video conversion services. Examples include CloudConvert, Zamzar, and Online-Convert.com. These are convenient for quick, one-off conversions, but they often have file size limitations and may not be suitable for sensitive or large files. Be cautious when using online converters and ensure the site is reputable to avoid malware or privacy issues.
-
Using VLC Media Player: VLC, a versatile media player, can also be used for basic video conversion. Open VLC, go to “Media” > “Convert / Save,” add your .wmv file, select “Convert,” choose the “Video – H.264 + MP3 (MP4)” profile, and set the destination file.
Converting the .wlmp Project File (Less Recommended)
Directly converting a .wlmp project file to MP4 is generally not possible. .wlmp files are project files, not video files. They contain editing information and references to the source video and audio files used in the project. They cannot be directly played or converted. The best approach is always to export the project as a .wmv file from Movie Maker, and then convert that .wmv file to MP4.
Some converter software might claim to support .wlmp files, but they usually just guide you through opening the project in Movie Maker and exporting it to a supported format.
Choosing the Right Conversion Settings
Selecting the correct conversion settings is crucial for balancing file size and video quality.
Resolution
Resolution determines the sharpness of the video. Higher resolutions (e.g., 1920×1080 – Full HD, 3840×2160 – 4K) result in better video quality but also larger file sizes. Lower resolutions (e.g., 1280×720 – HD, 640×480 – SD) result in smaller file sizes but lower video quality. Choose a resolution appropriate for the intended viewing device and platform.
Bitrate
Bitrate refers to the amount of data used to encode each second of video. Higher bitrates result in better video quality but also larger file sizes. Lower bitrates result in smaller file sizes but can introduce compression artifacts. A bitrate of 5-8 Mbps is generally suitable for HD videos.
Frame Rate
Frame rate (FPS) refers to the number of frames displayed per second. Common frame rates include 24 FPS (cinematic look), 30 FPS (smooth motion), and 60 FPS (very smooth motion, often used for gaming videos). Choose a frame rate that matches the original video’s frame rate.
Codec
Codec is the algorithm used to compress and decompress the video. H.264 (AVC) is the most widely used codec for MP4 videos, offering a good balance of quality and compression efficiency. H.265 (HEVC) offers even better compression efficiency but is not as universally supported.
Troubleshooting Common Conversion Issues
- Video quality loss: Experiment with different bitrate and resolution settings. Higher settings generally result in better quality.
- Audio synchronization issues: Ensure the audio and video tracks are correctly aligned in the conversion settings.
- Conversion errors: Try a different converter program or update your existing one.
- File size too large: Lower the resolution or bitrate.
- Conversion process is slow: Video conversion can be processor-intensive. Close other applications to free up system resources.
- Watermarks on converted video: This often occurs with free converter software. Consider upgrading to a paid version to remove watermarks.
Frequently Asked Questions (FAQs)
Here are some commonly asked questions regarding converting Movie Maker projects to MP4:
FAQ 1: Can I directly convert a .wlmp file to MP4?
No, you cannot directly convert a .wlmp file to MP4. A .wlmp file is a project file, not a video file. You must first export the project from Movie Maker as a .wmv file, and then convert the .wmv file to MP4 using a video converter.
FAQ 2: What’s the best free video converter for converting .wmv to MP4?
HandBrake is widely considered one of the best free video converters due to its open-source nature, powerful features, and lack of watermarks. Freemake Video Converter is another popular option, but it may include promotional offers.
FAQ 3: How can I reduce the file size of my converted MP4 video?
You can reduce the file size by lowering the resolution, bitrate, or frame rate. Experiment with different settings to find a balance between file size and video quality.
FAQ 4: Is it safe to use online video converters?
Online video converters can be convenient, but it’s essential to use reputable websites to avoid malware or privacy issues. Be cautious about uploading sensitive videos.
FAQ 5: What is the best resolution for converting to MP4 for YouTube?
YouTube recommends different resolutions depending on the aspect ratio of your video. For a standard 16:9 video, 1920×1080 (Full HD) is a good choice.
FAQ 6: How long does it take to convert a video?
The conversion time depends on the size of the video, the complexity of the conversion settings, and the processing power of your computer.
FAQ 7: What is a video codec, and which one should I use?
A video codec is an algorithm used to compress and decompress video data. H.264 (AVC) is the most widely used codec for MP4 videos and offers a good balance of quality and compression efficiency.
FAQ 8: Can I convert multiple videos at once?
Some video converters, such as HandBrake and Wondershare UniConverter, support batch conversion, allowing you to convert multiple videos simultaneously.
FAQ 9: Why is my converted video blurry or pixelated?
This usually indicates that the bitrate is too low. Try increasing the bitrate during the conversion process.
FAQ 10: Do I need to install any special codecs to convert .wmv to MP4?
Most video converter programs include the necessary codecs. However, if you encounter errors, you may need to install codec packs like K-Lite Codec Pack.
FAQ 11: Can I convert a video for playback on my iPhone or Android device?
Yes, choose a resolution and bitrate suitable for mobile devices (e.g., 1280×720 or 640×480, with a bitrate of 2-4 Mbps). Many video converters offer presets optimized for specific devices.
FAQ 12: What if my converted video has no audio?
Ensure that the audio track is selected during the conversion process. Also, check the audio codec settings to make sure they are compatible with your playback device. Common audio codecs for MP4 are AAC and MP3.
