The images have different color spaces, dimensions and image channels. How would you make a movie from that?
ImageColorSpace /@ images // Union
(* ==> {"Grayscale", "RGB"} *)
ImageDimensions /@ images // Union
(* ==> {{256, 256}, {512, 512}, {1024, 1024}} *)
ImageChannels /@ images // Union
(* ==> {1, 3} *)
You'd have to convert them all to the same format.
