Most people will go through their lives without having to give a video presentation. However, if it is a part of your profession, you may give presentations quite frequently. To be successful at it, you will have to make sure everything runs smoothly. To make sure of this you need to have good, reliable equipment and software. A presentation that loses power half way through won't get you many new clients and definitely won't make you popular with your boss.
If you are doing digital presentations you may need to have good software programs that allow you to download and transfer your images onto disks or DVDs. If you are using tapes, make sure your VCR is up to date. If you are using slides you will need good scanners and viewers to get your images across professionally.
