Script to export info from video field?

Would this do?

Just select the documents and run the script from the Tools menu.

The CSV file will be created on the desktop.

#target bridge   
if( BridgeTalk.appName == "bridge" ) {  
var videoInfo = new MenuElement( "command", "Video Info to CSV", "at the end of Tools" , "vidinf" );
}
videoInfo.onSelect = function () { 
var sels = app.document.selections;
if(sels.length <1) return;
var TimeNow = new Date();
var hours = TimeNow.getHours();
var minutes = TimeNow.getMinutes();
var seconds = TimeNow.getSeconds();
if (hours > 12) hours = hours - 12;
if (hours == 0) hours = 12;
if (minutes <= 9) minutes = "0" + minutes;
if (seconds <= 9) seconds = "0" + seconds;
var TodaysTime = "_" + hours + "-" + minutes + "-"+seconds;
var outCSV = File(Folder.desktop + "/" +decodeURI(Folder(app.document.presentationPath).name)  +TodaysTime.toString() + ".csv");
outCSV.open('w');
outCSV.writeln("FileName,Tape Name,Alternative Tape Name,Scene/Take,Date,Comment");
for(var a in sels){
var md = sels.synchronousMetadata;
var name = decodeURI(sels.spec.name);
var tapeName = ("'" +md.read("http://ns.adobe.com/xmp/1.0/DynamicMedia/","xmpDM:tapeName")).toString().replace(/^'/,'');
var altTapeName = ("'" +md.read("http://ns.adobe.com/xmp/1.0/DynamicMedia/","xmpDM:altTapeName")).toString().replace(/^'/,'');
var scene = ("'" +md.read("http://ns.adobe.com/xmp/1.0/DynamicMedia/","xmpDM:scene")).toString().replace(/^'/,'');
var logComment = ("'" +md.read("http://ns.adobe.com/xmp/1.0/DynamicMedia/","xmpDM:logComment")).toString().replace(/^'/,'');
var shotTake = ("'" +md.read("http://ns.adobe.com/xmp/1.0/DynamicMedia/","xmpDM:shotName")).toString().replace(/^'/,'');
var shotDate = ("'" +md.read("http://ns.adobe.com/xmp/1.0/DynamicMedia/","xmpDM:shotDate")).toString().replace(/^'/,'');
outCSV.writeln(name + "," + tapeName +"," + altTapeName +","+scene+","+shotTake+","+shotDate+","+logComment);
    }
outCSV.close();
}
