Editing Modes

Both a linear or a non-linear edit setup enable you to switch between the two modes of editing-assemble and insert editing.

Assemble Editing
When in the assemble mode of editing, the recorder will erase everything on its tape (video, audio, including the effects and graphics) even while replacing it with new information (Fig. 8.9). It is similar to what happens in our camera when we begin shooting. The moment we press the record but­ton, our camera begins to replace the old information on the tape with new information. The same happens in assemble editing as well. If the master tape already has some information (even if it is only a blank recorded), the recorder will erase it and replace it with new video and audio, with the effects and graphics. This, in effect, is like just transferring information from one tape to another. However, if there is already some signal on the master tape and you attempt assemble editing and do not do it accurately, it might result in glitches or a 'break' in the picture. This mode of editing is fast and does not require us to lay a control track on the master tape. This is, however, not the recommended mode of editing since programmes re­quire more than just 'copying' what has been shot onto another tape.

In digital editing, we mostly do assemble editing, that is, we only copy the footage onto a video layer in the Assemble Editing timeline and lay them side by side or on different layers, and add effects where necessary.

Insert editing-gives a choice in replacing audio and video

Insert Editing
Let us suppose we want to play music on a shot of children playing in a park, we cannot use assemble editing to do so. Here, insert editing comes in handy. In the insert editing mode (Fig. 8.10) only the video or audio of our choice is re­placed on the master tape. Take the ex­ample mentioned above. We have al­ready edited a scene of children playing in a park. The master tape already has ambience sound of children playing. But we want to replace the ambience sound with some soft music. We can select only audio on the recorder and replace the ambience sound with music from the player. Remember that for insert editing to be successful, we must first record a continuous control track for the whole length of the master tape.

In other words, when editing in insert mode, we do not transfer fresh control track to the record videotape. Instead, we use it as a guide and position reference for laying down the inserted video on the tape.

In digital editing, although we first lay the shots, in assemble mode on a video layer in the timeline, we can switch to insert mode by inserting another video layer. We can then insert a different shot on the other video layer. The computer will then play back the video on the lower layer and switch to the video on the upper layer, and again back to video on the lower layer.
