 Pre-read Edits: Some high-end digital video decks can actually perform transitions by
using the master tape as one of the sources. A digital VTR with the ability to pre-read
video off the tape before recording is required. Pre-read is a technical feature that
allows a deck to read the signal off tape, send it to a device for processing, and then
record the processed signal back onto the same tape in the same location. In this
case, the record deck actually becomes the source deck, or one of two source decks
in the case of performing transitions.
Pre-read transitions always begin with the master deck and then dissolve to a source
deck. For example, a pre-read dissolve is performed in an online edit suite by making
a cut to the master tape signal, then dissolving to another source deck.
In the example below, the first event is a cut to Reel 002. The second event is a cut to
the master tape itself, which then dissolves to Reel 002.

 Generic Edits: This option allows transitions from two places on the same source

nonlinear editing system, or if specifically requested by your online editor. Some
online editors may prefer to receive generic transition EDLs and modify them
manually.
