The DVApp application supports the following modes:



Preview: Renders DV from the camcorder to a video window.

DV to type-1 file: Captures DV data from the camcorder to a type-1 DV file.

Type-1 file to DV: Transmits data from a type-1 DV file to the camcorder.

DV to type-2 file: Captures DV data from the camcorder to a type-2 DV file.

Type-2 file to DV: Transmits data from a type-2 DV file to the camcorder.

The capture and transmit modes also perform preview. Each of those modes has a No Preview option as well, which disables preview. Capturing without preview is more efficient and can reduce the number of dropped frames.



The application starts in preview mode. To select another mode, choose a mode from the Graph Mode menu. For each mode, DVApp builds a filter graph that supports the functionality of that mode. To save the graph as a GraphEdit (.grf) file, select Save Graph to File from the File menu. Quit DVApp before opening the file in GraphEdit.
