The Firewire Video Page

On this page you can specify which Firewire/DV device should be used to provide the raw video data, with what resolution and frame rate. Remember that a higher resolution and higher frame rate will produce more data, requiring more processing power and more network bandwidth.

The Scaled Height field allows you to scale the video resolution down in case the default Firewire resolution would require more bandwidth or processing than you wish to use.

The Convert To Square Pixels option allows you to optimize the output for your intended client players. or data does not use perfectly square pixels, but square-pixel content is clearer on monitors that display square pixels, such as most non-widescreen monitors.

The Width Correction options allow you to optimize the raw data for your intended encoder, which may require the video's width and height to be a multiple of 8. If you need width correction then Pad is usually the best choice because it just adds additional black space at the edge of the video, instead of distorting the main content by stretching.

The Frame Rate fields lets you choose the number of frames per second for the raw video data produced by the Firewire device.

The worker drop-down choice allows you to choose what computer this component should run on, for instance if the camera is attached to a different computer that is available via the network. This allows you to distribute tasks across several server computers. See the Deployment chapter to learn how to create extra workers. The Configuration Assistant would then offer these workers in the drop-down choice after connecting to their manager.
