This isn't a problem for simple editing work, but without dedicated audio hardware problems can arise in synchronising the audio and video tracks on longer and more complex edits. Video capture cards are equipped with a number of input and output connectors. Additional sockets can be of benefit though, since complex editing work often requires two or inputs. Some cards are designed to take an optional TV tuner module and, increasing, video capture cards actually include an integrated TV tuner. Less sophisticated cards require a separate graphics adapter or TV tuner card to provide this functionality.
Video editing Broadly speaking, there are two types of video editing.
One involves editing directly from one tape to another, and is called linear editing. The other requires that the sequences to be edited are transferred to hard disk, edited, and then transferred back to tape. This method is referred to as non-linear editing. A PC can be used to for either type of process. For linear editing, it simply controls the source and record VCRs or camcorders.
