MP4 file format has been widely used to store digital videos. If you have files in this format, there will be times when you need to combine multiple MP4 files together. For example, when you have downloaded your favorite TV movies or episodes from the Internet or want to share some videos that were shot during your holiday trip.

MP4 Merger: How to Merge/Join/Combine MP4 Files
1. Import MP4 files to merge
You can either click "Import" button on the primary window and locate MP4 files on your computer, or just drag and drop MP4 files from Windows File Explorer to the User's Album. In the User's Album, all imported MP4 files will be displayed in thumbnails and be easily added to the Timeline for editing without touching the original MP4 files.
2. Drag and drop MP4 videos on the timeline
To merge MP4 files, select multiple MP4 files in the User's Album while holding down Ctrl or Shift key, and then drag and drop to the video track on the Timeline. All MP4 files will be played one after another without a gap after saving to your computer.
3. Add transitions between MP4 videos (optional)
To control how the movie plays from one MP4 clip to the next, you can add transitions between two clips. To do so, change to Transition tab, and drag the desired transition to the MP4 video that requires a transition. You can also right click any transition and a menu will appear. Choose "Apply to All" and "Random to All" from the menu to add the same transition to all clips, or apply transition randomly.
4. Merge MP4 files into one
It's a good idea to preview the merged MP4 video by clicking Play button. When you are happy with the result, click "Create" button to merge MP4 files to a single video. In Format tab, select any format you want from the list. All popular video formats are supported. But in this case, MP4 format works if you want video still in MP4 format. To play the merged MP4 files on iPod, iPhone, iPad, choose "Device" and select a target device. You can also directly upload the combined video to YouTube with your account, or burn MP4 to your DVD player to enjoy on wide screen TV.
