CELL PREVIEW/CUT WINDOWS

 

DOMAIN: TITLES AND MENUS

 

Cell cut feature (available in MENUS and TITLES) allows the user to cut a cell in different ways

- Cut from the start up to a selected I-Frame

- Cut from a selected I-Frame until the end of the cell

- Cut all except between two selected I-Frames

- Cut "inside": Remove the frames between two selected I-Frames

 

Cuts are GOP based, and are not completely clean (the audio is cut in a brute way). VobBlanker detects if the initial selected GOP is a non-closed one and automatically changes it to broken to allow the settop to play it w/o problems. Also, VobBlanker warns the user if, as consequence of the cut, some subs are going to be orphan. In this case the best option is to select other GOP.

 

Multiple cuts (but only one per cell) are allowed in the same VobBlanker session.

 

In the case of "cut inside", VobBlanker offers the possibility to split the cell in two parts. This method guarantees a cut without audio/synch problems. If the cell is split, the user is allowed to add a new program/chapter automatically, but this procedure has impact in VM commands, which are NOT modified by VobBlanker

 

Cell Cut operation open a new window: This window can be opened using the Prev/Cut button or the popup menu (mouse right click). in the Cells  area of Cells dlg window
