A very popular method right now for making quick, inexpensive, yet great quality videos is the use of power point type slides. You can use Microsoft Power Point, or if you don’t have that on your computer, you can use the free Open Office suite which includes Impress. I have both on my PC and I actually use Impress more than Power Point. Both programs are very good and will get the job done for you. You can do this very simply, or you can go with graphics and get really technical with it. The simplest method is to copy 40 to 50 words from your article and paste them into a slide using a larger font size. If your article is 400 words, and you use 50 words per slide, you will need 8 slides for the content. Use a title slide at the beginning and a call to action slide at the end and you will have a total of 10 slides in your video. Then all you need to do is record yourself reading the slides and put them together. I will show you a couple of ways to do that.
A variation of the above is to use only a dozen words or so and make them really large. This makes for a faster moving presentation with more slides. In this method, the listener/reader cannot read ahead; they have to pay closer attention. You have more options doing it this way in that you can become more creative by making the line of text run in different directions on the various slides. It takes more time to put it together, but it makes for a more professional looking presentation. Once they are completed, then record yourself reading the slides and put it together as a video.
A third option would be a combination of the first two. You could use the 50 word idea and place each sentence into the slide one at a time as the line is spoken. This would require several slides more, but it is very effective. The first slide would have only the first sentence and the second slide would have the first sentence plus the second sentence and so on until the last slide contained the full 50 words.
A fourth option is to outsource the creation of the slides. Decide how you want them laid out and hire someone else to create them to your specifications.
