Using free video editing software is a convenient way to edit your videos. Additionally, most of them are so easy to use that they are great for starting editors. You may want a video editing program if you need to extract audio from a video clip, add a different sound, truncate parts of the video, add subtitles, or merge video files. Most bloggers need a video editor of some sort. Since most free video editors limit their features to advertise their professional versions, you may find roadblocks that prevent you from making advanced edits.
