Repairing corrupted FLA file and/or converting SWF to mpeg

so this feels like it would take someone who knows what they're doing a finite time, and me several days:

THE ISSUE: -- the data is in the file and the corruption is finite

THE SOLUTION: one or several scripts to automate pulling the good out of the bad

Merlin AI - started to come up with some JSFl...but it's beyond my capacities to attempt it...

ANYONE?

/**
* Exports every symbol in the library to its own .swf file.
* @9397041 {String} destFolderURI - e.g. "file:///C:/Temp/Exports/"
*/
function exportAllLibrarySymbols(destFolderURI) {
var doc = fl.getDocumentDOM();
if (!doc) { alert("No open document."); return; }

var lib = doc.library;
var items = lib.items;
for (var i = 0; i < items.length; i++) {
var name = items[i].name;
// sanitize filename
var safeName = name.replace(/[^a-z0-9_\-]/gi, "_");
var outURI = destFolderURI + safeName + ".swf";
lib.exportSymbol(name, outURI);
fl.trace("Exported " + name + " → " + outURI);
}
}

// Example usage:
exportAllLibrarySymbols("file:///C:/Temp/MyFLA/Symbols/");

/**
* Finds and replaces text in every frame’s ActionScript.
* @9397041 {String|RegExp} findPattern
* @9397041 {String} replacementText
*/
function batchReplaceInFrameScripts(findPattern, replacementText) {
var doc = fl.getDocumentDOM();
var timeline = doc.getTimeline();
var layers = timeline.layers;

for (var li = 0; li < layers.length; li++) {
var layer = layers[li];
var frames = layer.frames;
for (var fi = 0; fi < frames.length; fi++) {
var frame = frames[fi];
var scriptText = frame.script;
if (scriptText && scriptText.search(findPattern) !== -1) {
var newText = scriptText.replace(findPattern, replacementText);
frame.script = newText;
fl.trace(
"Replaced in layer “" + layer.name + "”, frame " + (fi+1)
);
}
}
}
}

// Example usage: rename oldFunc() → newFunc()
batchReplaceInFrameScripts(/oldFunc$/g, "newFunc(");
