Creating GIFs in bulk?

A related topic here:

https://community.adobe.com/t5/photoshop-ecosystem-discussions/script-to-generate-gif-from-folder-of-images/td-p/14438104/page/2

I would have probably just used Bridge and Image Processor Pro.

This is not a very clean script, much of it is converted from an action for fast prototyping. Anyway, it works for one inputFolder variable...

#target photoshop

var inputFolder = Folder.selectDialog('Please select the input folder:');

cTID = function(s) { return app.charIDToTypeID(s); };
sTID = function(s) { return app.stringIDToTypeID(s); };

function createGIFanimation() {

  // Create Frame Animation
  function step1(enabled, withDialog) {
    if (enabled != undefined && !enabled)
      return;
    var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
    executeAction(sTID('makeFrameAnimation'), undefined, dialogMode);
  };

  // Make Frames from Layers
  function step2(enabled, withDialog) {
    if (enabled != undefined && !enabled)
      return;
    var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
    var desc1 = new ActionDescriptor();
    executeAction(sTID('animationFramesFromLayers'), desc1, dialogMode);
  };

  // Extend Frame Selection to all 6 frames
  function step3(enabled, withDialog) {
    if (enabled != undefined && !enabled)
      return;
    var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
    var desc1 = new ActionDescriptor();
    desc1.putInteger(sTID("animationToFrame"), 5);
    desc1.putBoolean(sTID("animationFramesContiguous"), true);
    executeAction(sTID('animationFrameExtendSelection'), desc1, dialogMode);
  };

  // Set frame delay
  function step4(enabled, withDialog) {
    if (enabled != undefined && !enabled)
      return;
    var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
    var desc1 = new ActionDescriptor();
    var ref1 = new ActionReference();
    ref1.putEnumerated(sTID("animationFrameClass"), cTID('Ordn'), cTID('Trgt'));
    desc1.putReference(cTID('null'), ref1);

Questions:

1) Is it acceptable that the files are stacked in alpha/numeric filename order? So file001 is the first frame, file006 is the last frame?

2) Do all frames have the same delay? If so, how many seconds between each frame?

3) Is it acceptable that the saved gif file is named after the folder and that the gif file is saved in this folder with the original six images?

OK, incremental progress...

I have a script that does the following:

1) Stack all files in an input folder

2) Create frame animation

3) Make frames from layers

4) Select all frames

5) Set animation options delay/time

6) Export save for web as gif animation to input folder

So at the moment, if you were happy to select 200 separate input folders, you would have a result...

The key to the automation will be step of processing the 200 separate folders individually in a loop.

I've seen scripts that can process files in a top level/root folder, ignoring sub folders.

I have also seen scripts that can process all files and folders under the root folder.

But I've never seen a script to process a sub folder one at a time.

I believe that Image Processor and Image Processor Pro can do this, so it is obviously possible.

Worse case, possibly an action could play a script that processes the files in each sub folder, with the action being run by IP or IPP.

So work out how to do this for one folder and the other 199 may be "easy".

Edit: I'm not sure if these scripts can produce an animated GIF without modifications so this may be harder than expected...

I guess, one could automate the task with a Script in Photoshop. 

Have you found some more efficient/easy approach yet?
