Cutting together recorded material according to a prepared scheme such as a rough cut or EDL. EDLs can be used to directly control conforming in an online edit suite (auto-conforming). The time to conform varies widely, from a tape-based suite which takes much longer than the finished program’s running time, to a nonlinear online suite with true random access to all material. This reduces time by loading material in C-mode (see below) and the conforming itself takes only a moment and still allows any subsequent adjustments to be easily made.
Note that with in-server editing, material may be loaded onto the server as an independent task, rather than involving the edit equipment itself. This circumvents so called loading time and further reduces the total time to produce the finished program. The same is also true of nonlinear edit systems with the bandwidth to support loading as a background task.
There are a number of established ways, or modes, of approaching video editing.
A-mode is a simple sequential method, starting from the beginning of the program and going through to the end.
B-mode uses all shots from one particular source before the next source is used (i.e. checkerboarding).
C-mode is similar to B-mode but works sequentially through the playback source rather than the record tape.
D-mode is similar to A-mode except that dissolves and other transitions are performed last, at the end of the conform.
E-mode is similar to C-mode but with transitions at the end, as in D-mode.
Note that the logic of the above modes is based on the characteristics of videotape. As tape is increasingly replaced by other recording media, network conform is becoming increasingly used. Part of the work of the Advanced Media Workflow Association (AMWA) is to provide new industry standards for this important area.
