How to Edit MP4 (MPEG-4) with MP4 Video Editor for Windows, Step by Step (Windows 10 Compatible)
Step 1. Import MP4 videos to video editor
You can click “Import” to import files from your PC or drag and drop files directly into the User Album. All added files will be displayed as thumbnails in the album, and you can preview them in the preview window on the right side. Keep in mind that common photo and audio formats are also supported for better home movie creation.

Step 2. Edit and customize MP4 files
Then, drag the files to the video track on the timeline for editing:
1. Basic video editing functions include: rotate, cut, adjust contrast/saturation/brightness, slow/fast motion, voice changes, etc.
2. On the timeline, drag and drop videos and audio to automatically trim them, and click to detach them.
3. You can also add custom subtitles to your videos to convey the meaning more clearly.
4. In addition, many video effects (more than 50) are provided to make your videos more personalized and special.

Step 3. Add scene transitions (optional)
Click on the “Transition” tab in the main window of the program and you will see that you are offered more than 50 scene transition effects. You can drag the likes to the video on the video track to apply them. If there’s a particular template you like, you can add it to your favorites so you can easily find it at other times. If you don’t want to choose transitions one by one, you can let the program choose them randomly by right-clicking and selecting the “Shuffle to All” option.

Step 4. Share your videos in a variety of ways.
When the editing is complete, click “Create” to save the edited MP4/MPEG-4 files in another format or in playable formats on portable devices. You can also share your video creations directly on YouTube or burn videos to DVDs for better preservation.

Tips: MP4 files have become a popular file type on portable devices such as MP3 players, MP4 players, and file-sharing sites due to their small size, and therefore, shorter upload and download time. However, MP4 files are not widely known by many popular video editing software. Therefore, please, when choosing a video editing program, make sure that it recognizes MP4 files.
