Saving an animated gif in RGB mode instead Indexed

[wallaceh3639989]

Does somebody know how to save an animated gif in RGB mode?

I downloaded this gif and when I open it in Photoshop, at the menu mode, RGB is checked instead Indexed as usually is a .gif format.

Not posible you can save an Image sequence.    Gif color support is poor a max a 256 mapped colors is posible. For good color render a MP4 video instead of an animated gif

What you expect to see? Indexed Color selected? Indexed color mode does not support layers, by the way and your GIF will be useless.

After FX will do this.
