About Video Interfaces, Signals, and Connectors
This section describes common types of video interfaces, signal formats, and connectors.
Video Interfaces
Final Cut Pro allows you to use a wide variety of video interfaces for capture and
output. The following section shows examples of the most common types of video
interfaces available.
FireWire for DV
You can use the built-in FireWire port on your computer to capture and output to almost
any DV device, including DV, DVCAM, DVCPRO, DVCPRO 50, and DVCPRO HD devices.
In this configuration, you only need your computer and a supported DV device. For
more information, see Chapter 11, “
FireWire for Uncompressed Digital Video
Interfaces such as the AJA Io connect to your computer via FireWire. However, instead
of transferring compressed DV signals, the AJA Io transfers an uncompressed
component 4:2:2 signal via FireWire. The AJA Io has a wide range of digital and analog
connectors, as well as RS-422 device control.
Important:
Although this type of video interface uses FireWire, it is not used to
connect DV devices. If you want to capture or output DV video, you can connect your
DV device directly to the FireWire port on your computer.
