Your banner does not have a transparent background is most likely the problem.
To make sure it does transparentize the background in ImageMagick using paint. With the Matte function.
Or you can make the background Black and composite 'Multiply'
only the text will be glitter littered. You can then transparent the black background if you want to. I suggest you take it to gifworks to do that though. As ImageMagick and animation don't like one another all that much.
Your other posts on animation challenges you have had/are having can be solved by remembering to make the area you want to glitter transparent. Make a 'block' of glitter that is the same size as your image. Now composite the transparent in part image ATOP Center the block of glitter. You will need to do this for each part you want a different type of glitter.
Also be aware that jpg format does not support transparency. It defaults when output to a solid color background and one frame so no animation. Use gif for animations always.
PNG also supports transparency. But PNG is not meant for a multi frame animated image. PNG has some quirks and many Perks!
So gif format for animation and for transparency.
