Long videos not only occupy extra storage space but are also difficult to share over social media, emails, and other mediums. Here, trimming the unwanted parts of your videos will reduce the size, thus making it smaller and easy to manage. To ensure that MP4 videos are trimmed without any quality loss, the right tools and software must be used. Listed below are the best tools to trim MP4 video.

Part 1. How to quickly trim MP4 Video with VLC

VLC is a popularly used media player app that is compatible with all platforms and devices. Besides playing your media files in an array of formats, the player is capable of performing an array of other functions as well. Some of these features include video conversion, merging, trimming, and others. So if VLC is already installed on your system, you do not need to use any other program to trimming your MP4 files. The trimming function works where you can record the part of the video that is required. Thus you can choose the video from point A to point B that you want to cut and save.

Steps to trim MP4 using VLC Media Player

Step 1: Launch the VLC media player on your system. Open the View tab on the main interface and click next to the Advanced Controls option. The recording button will now appear at the player interface.

The icon of A to B can also be selected to choose the video part that you require.
