How to edit an MP4 file?

Using Video Splitter from SolveigMM you can:

  • split video into several files;
  • cut out fragments from the video both at the beginning and at the end of the recording, and from the middle;
  • simultaneously cut out several fragments of the source file (for example, to remove ads) with frame-by-frame precision;
  • flip the video vertically or flip it horizontally, etc.

Sequence of work in the program

1. To edit MP4 videos install SolveigMM Video Splitter on your PC. When downloading the video editor please note that the version of the program must match the bitness of the computer's operating system.

2. Open the program to edit an MP4 file.

3. To import the required file into the MP4 editor go to "File - Add multimedia files". Select the MP4 for editing by left-clicking on its name. Or use the Enter key.


Also the file for video editing must be dragged onto the timeline manually.


4. Further steps of MP4 editing depend on the goals.

a. If you need to split one video file into several fragments, place start / end markers on the footage timeline. To improve the accuracy of editing MP4 you can use the visual timeline which allows you to identify the necessary frame. A more detailed description of the process can be found here.

b. If you need to flip the video by 90, 180, 270 degrees to the left or to the right or flip it vertically or horizontally use the functions in the Rotate Video section.

c. If you need to trim the video, place the start / end markers for each fragment you want to trim, move the cursor over the area between the markers and click on the scissors button. In this case, the fragment will be marked as “Cut out”. Pressing the button again will enable you to mark the fragment for keeping.

d. If you need to remove an unnecessary fragment or several unnecessary fragments from the video sequence while editing an MP4, use the visual timeline of the video editor for MP4 (for frame-by-frame precision), place the start / end markers on the timeline of the video sequence using the "Add marker" button or a similar command in the context menu. Then select the fragment that you want to cut from the final video, right-click on it and use the "Cut out selected fragment" command. Thus, to edit MP4 videos you need to select all the fragments to be cut out from the source file, and in each of them click on the button with the scissors.


5. To complete the editing MP4 process do not forget to save the work done. In the "Save as" window that will appear after clicking the "Save" button select the file name and the path to save, click the "Save" button.


After these simple steps in the Windows MP4 editor the program will start editing MP4. When the process is over you will be prompted to open the folder with the resulting file.
