b. The limitations of audio-visual media
1) When it will be used, the video equipment must be readily

available at the place of use; and match the size and format of the
pica video that will be used.
2) Writing a script or video scenario is not an easy and time-

consuming job.
3) Video production costs are very high, and few people can afford

them.
4) If the image on the pica video is transferred to the film, the result
is poor.

5) Small monitor screens will limit the number of viewers unless
network monitors and video projection systems are expanded.

6) the number of fonts in graphics for video is limited, which is half
the number of graphics letters for movies/images.
7) If you use colour graphics on a black and white TV, be very

careful. For example, red and green colours with a specific
density will look the same on a black and white TV screen. As
much as possible, try to make graphics with black and white

colours or groups of grey.
8) Rapid changes in technology have made video system limitations
an ongoing problem.

1) Manuscript is a story text displayed by the players, which contains

documentary script or a dialogue script consisting of several film
players. The manuscript is made by the teacher concerned in

consultation with several other experts, such as content experts,
communication experts, and others.
