MPEG-4 (better known as MP4) is a video format created to facilitate video sharing over the web as well as multimedia storage.
MP4 is a popular format among computer users, therefore there are numerous video editing apps that come with support for this format.
More precisely, MP4 editors will allow their users to cut, merge, split, or join their movies with ease.
Additionally, some MP4 editing apps will also allow users to apply effects and crop the videos.
By adding text or image watermarks onto MP4 video clips, users will be able to make sure that nobody else will claim to be the owner of the video.
