Working range of this project is 55 frames long
(frame 130 – frame 185), however, the difficulties on this
part are fairly challenging. Figure 2 indicates a number
of unwanted objects, which have been marked at frame
165. For instance, creating a clean plate for an inner part
of the brief case is needed, because the character grabs
one of toys from the opened brief case. A clean empty
space should be created after erasing the toy from its
original position. In addition, several places also need
clean plates, such as shadow of the toy on the wall and
the man’s chest when he was passing the toys from one
person to another.
