Hi, new user here.
I want to do something fairly simple, but it's just not happening.

I want to take one gif, and overlay another (some snow, for Christmas, of course), so they both play at once.

Here's what I have tried:

Opening gif A as layers, opening gif B as layers, manually moving them so they alternate in the layers dialogue box (so it runs background, background, frame 1, frame 1, etc), then merging down each frame to its matching one (i.e, frame 1b merging down to frame 1a).

I tried changing the mode of the snow gif to "overlay" which does... nothing? I tried a snow gif that claimed to be transparent and the snowflakes turned out black (??!). The "scale layer to image" command also didn't do anything, so the black snowflakes were only on one part of the gif.
For gif A, the timing is 200ms; for the black snowflakes it says it is 100ms, I can't see where to edit this to make them match unless changing the name in the attributes box will affect how it runs.

Am I at least on the right lines? If so, is there anyway to arrange, match the scales, and merge down the layers as a batch?
Thanks!

There is an animated snow script that you can use to overlay snow onto you gif image.
Much like what can be seen it my signature image below.

You can pick the script up here...

Perfect!
Thank you very much!

Of course you need to have the same number of frames in both animations, and they need to have the same timing. To achieve this you may have to make adjustments in at least one image (duplicating frames and dividing frame delay by two, for instance). Once this is done there are scripts to merge the layers (such as my own interleave-layers).

OK
way back then,when I joined the forum,I wanted to add a gif into another,and Someone had a scrip for it.
I can't remember at all who and how.All I can remember is that it had like a green croos to move and adjust the gif into the other.
That was October 2011 ,and I said i posted the working Gif's but I don't see it anymore
