Trimming an MP4 Video on a Microsoft Windows 10 system
On a Microsoft Windows 10 system, if you wish
to save just a portion of a video that is in MP4 format,
you can do so if you are viewing the video in the Movies &
TV application, which is the default program for playing videos,
by clicking on the pencil icon near the bottom, right side of the
window. If you double-click on the file for the video, it will likely
open in the Movies & TV app, but if that is not the
default program for playing videos, you should be able to open it
in the program by right-clicking on the file and choosing Open
with then selecting Movies & TV. Once you click on
the pencil item in the application, you can then choose Trim
which appears beneath Edit in Photos. You should then see white
circles at the beginning and end of a white line at the bottom of the
video that represents the length of the video. You can drag those white
circles to the points in the video that you wish to be the starting and
stopping points for the video. E.g., if I had a video that was several
hours long, but I only wanted the first hour of the video, I could
drag the white circle at the bottom, ride side of the window to the
left until I saw 1:00, which represents 1 hour and 0 minutes. Once you
have just the portion of the video timeline you want isolated with the
white circles, click on Save as, which appears near the top,
right side of the window next to an icon that depicts a pencil over a
3
1/2" floppy disk. You can then chose a file name you want for the
new copy as the program doesn't change your original file, but makes a
copy with just the portion of the original file you opted to save. By
default, the program will append "_trim" to the original file name.
If it is a large video, you may need to wait a few minutes for the new
file to be created from the larger original file.
