Channel Packing Images Sequences

[blanks]

Hi, I have a situation where I have potentially hundreds of images in an animated frame sequence. I would like to pack the frames into the channels of new images.

For example:

input 1 becomes output 1 Red channel
input 2 becomes output 1 Green channel
input 3 becomes output 1 Blue channel
input 4 becomes output 1 Alpha channel
... but then....
input 5 becomes output 2 Red channel...and so on

An input folder with 100 frames packed into the R, G, B & A channels resulting in an output folder of only 25 images.

I think this should be possible, but I cant work out how. I use Imagemagick with .BAT files to pack sprite sheets and things, but I dont know how to do this.

I'm an artist, not a programmer so any advice or examples of this in windows batch style would be greatly appreciated.

Thanks you for any help you can offer.

Obviously, this will work only if your inputs are grayscale. The task is simple:

Code: Select all

magick in1.png in2.png in3.png in4.png -combine out1.png

Repeat for all your inputs.
