I am trying to add gifs to my video as an overlay type of thing; I have done it multiple times in the past but all of a sudden it just says "Add Media Failure. This type of file is not supported, or the required codec is not installed." Some of my gifs have work and others don't, but they are all .gif files.
Were all of the GIFs created by the same program in the same way -- Say, using Photoshop Elements?
GIFs are a rather limited format, by the way. Aside from incorporating animation (which Premiere Elements won't recognize) they really have few advantages as media for a video project. Why not use JPGs, PNGs or PSDs?
