Hi N,
I'll be VBing later.
I'll need to study you explanation more, but I think I can do what you show, and have all of the letters, numbers and 4x exclamation marks, in both sound and image form.
I mentioned earlier, that when I shortened the video track letters, they cut in half, I can see in you bottom image where the cursor is, the letters have dissapeared, so now I think my cutting in half, is what happens, in the time line. In other words the letter stops being shown there.
I hope to only show the video letter for a flash, so not the full length of the sound, but at the beggining end or middle, depending on how it looks later.
An yes, it is good fun!
Thanks, C.
