Once you have transferred your digital video files to your computer you can enhance them in various ways by using video editing software. For example, you can add colorful titles or suitable background music, delete unwanted scenes completely, change the order of scenes and add a commentary or special effects such as fade-in or fade-out. You can improve the quality of your video files by changing the brightness, contrast or colour balance.
Digital video editing can be carried out in two different modes, linear or nonlinear. In linear editing you have to start from the beginning of the video and move through it until you find the scene you want to edit.With non-linear editing you can go directly to the scene you want to edit, without having to go through all the earlier scenes in the video. The choice of editing mode depends largely on the video recording medium used. Magnetic tape can only be edited in linear mode as it is necessary to play through the tape until you reach the scene you want to edit. With random-access media, like CDs/DVDs, hard disk or flash memory it’s possible to go directly to any scene in the video, so you can use either linear or non-linear editing.
Once you have edited your video, you can store it in a variety of formats, depending on the playback device you want to use. If you prefer, you can store them on optical media, such as CD or DVD for playback on DVD players. You can also capture single frames from a video and store them as still images in .jpg or .png formats or you can extract clips from your video and upload them to video file sharing sites like YouTube or email them to your friends.
Whatever you do with video files you should keep copyright law in mind. You can do what you like with videos you have created yourself, but you should not edit or copy copyrighted video files without the explicit permission of the copyright owner.
