adding sound to animated GIF file

[#1]

I have a couple of animated .GIF files that I would like to add sound to....
does anyone know how to do this? and give me some pointers, please..... ?

[#2]

That's not really possible, the GIF container doesn't support sound. Unless you want to repackage it into some other format?

Stream a MP4 container.

OK... Thanks for the pointer.... Have changed it to a MP4 file, but need to make it repeat itself several times, as, at the moment it is about 3 seconds long...
I think I can now add the sound to the file with "Video Pad Editor".... but need to record the sound first...
As Always,..... this forum is a mine of useful information.... Thanks guys
