i'm using these resources: http://www2.le.ac.uk/offices/ld/resources/presentation/visual-aids , and I'm copying some points to consider from this website.
Video (DVD or VHS)
Video gives you a chance to show stimulating visual information. Use video to bring movement, pictures and sound into your presentation. Always make sure that the clip is directly relevant to your content. Tell your audience what to look for. Avoid showing any more film than you need.
Designing visual aids
There are many different rules for designing visual aids, some of which will apply directly to different kinds of equipment. In general, sticking to the following guidelines will produce high quality visual images:
- use one simple idea for each visual;
- make the text and diagrams clear and readable;
- avoid cluttering the image;
- keep your images consistent (use the same font, titles, lay out etc. for each image);
- make sure your images are of a high quality (check for spelling and other errors).
Always remember that an audience should be able to understand a visual image in a matter of seconds.
And finally ... practice
Always check your equipment to make sure that it:
