This is an example of a magician's promo video you can put together using free or cheap resources. You can use any video editor to do basic cuts and in this case I used an ai music generator to create the song. The video is just a bunch of small clips over the last 45 years.

For those who are asking, my video editor was Filmora, but there are many free editors available including Divinci. The song was generated by an app called mozart ai, but there are others available. I try to record as many shows as I can for quality control and measure audience reactions. Even if all I can use for part of a demo real, 2 seconds of a trick climax , it can really make the total video better.
