I need to make 50 picture in to a video. I also need a lead-out image to end the video. Each picture is a little different size, and some pictures might stay on the screen a little longer than others if their message is longer. So one picture might say 1 word and needs to stay on the screen a short amount of time. The next might be 5 words and has to stay on longer so you can read it. I need to add audio, I have already bought the audio file,, just need it added. Then lastly I need an image created that is simply like a white text on a black background but I need it animated as if someone is writing it with a pen.
