How to render a mp4 animation from jsx script?

I have some complex automation in Photoshop based on a jsx script that calls some actions to create both a static image and an animation automatically.

The logic and sequence in the script is working perfectly fine and the only thing that I still need to figure out in my script is how I can have the jsx script to execute the same export as I would get by clicking on File > Export > Render Video

I want my script to set all the options and perform the export automatically without user interaction.

 

Here is a snippet of the code just to show where I would place the render if I can discover how to do it.

 

var minhapasta = File($.fileName).parent.fsName;

var basenome = prompt("Escreva a base do nome de arquivos para usar! (evite acentos e caracteres especiais", "my_test_files"); 

var doc = app.activeDocument;

var jpgOptions = new JPEGSaveOptions();
jpgOptions.quality = 12;
jpgOptions.embedColorProfile = true;
jpgOptions.formatOptions = FormatOptions.PROGRESSIVE;
if(jpgOptions.formatOptions == FormatOptions.PROGRESSIVE){
jpgOptions.scans = 5};
jpgOptions.matte = MatteType.NONE;

doAction("pedaco1","Marcus Tavares - auto");
//first save as static image (working fine)
doc.saveAs (new File(decodeURI(minhapasta) +'/' + basenome + '01' + '.jpg'), jpgOptions, true);
//then just after saving a copy as static image, I should have the block that renders the animation that is already created by the action and name it using this: decodeURI(minhapasta) +'/' + basenome + '01' + '.mp4'

 

Could you please help with this? I searched everywhere and could not find a reference so I could base in it.

 

Thanks!

That was exactly what I was looking for. I used script listener and this cleaner script to translate the captured code into a more readable javascript code.

For others who may arrive in this thread in the future, this is the function for exporting the timeline as MP4.

function export2(directory, name2, ameFormatName, amePresetName, useDocumentSize, frameRate, manage, selectedFrames, quality, Z3DPrefHighQualityErrorThreshold) {
	var s2t = function (s) {
		return app.stringIDToTypeID(s);
	};

	var descriptor = new ActionDescriptor();
	var descriptor2 = new ActionDescriptor();

	descriptor2.putPath( s2t( "directory" ), directory );
	descriptor2.putString( s2t( "name" ), name2 );
	descriptor2.putString( s2t( "ameFormatName" ), ameFormatName );
	descriptor2.putString( s2t( "amePresetName" ), amePresetName );
	descriptor2.putBoolean( s2t( "useDocumentSize" ), useDocumentSize );
	descriptor2.putDouble( s2t( "frameRate" ), frameRate );
	descriptor2.putEnumerated( s2t( "pixelAspectRatio" ), s2t( "pixelAspectRatio" ), s2t( "document" ));
	descriptor2.putEnumerated( s2t( "fieldOrder" ), s2t( "videoField" ), s2t( "preset" ));
	descriptor2.putBoolean( s2t( "manage" ), manage );
	descriptor2.putBoolean( s2t( "selectedFrames" ), selectedFrames );
	descriptor2.putEnumerated( s2t( "renderAlpha" ), s2t( "alphaRendering" ), s2t( "none" ));
	descriptor2.putInteger( s2t( "quality" ), quality );
	descriptor2.putInteger( s2t( "Z3DPrefHighQualityErrorThreshold" ), Z3DPrefHighQualityErrorThreshold );
	descriptor.putObject( s2t( "using" ), s2t( "videoExport" ), descriptor2 );
	executeAction( s2t( "export" ), descriptor, DialogModes.NO );
}

//call it like this
var minhapasta = File($.fileName).parent.fsName;
export2(new File( minhapasta ), 'myvideo.mp4', "H.264", "1_High Quality.epr", true, 23.976, true, true, 1, 5);

Do you have Adobe Scriptlistener plug-in installed. If you do use file>Export>Render Video... fill in the dialog for the way you want to encode and save the video.  The create a Javascript render function for your script using the action manager code recorded by Adobe plug-in. After your script run the action  and save a jpeg file add a step that uses the function you created to render a video. .

      Thanks for this, I'm trying to run this as a batch on a folder of images to export multiple videos, how do i retain the original names to export the videos date stamped or number sequenced? As an action using the render to video function it exports with the same filename, so keeps over writing the original, also with your script it only saves as myvideo.mp4, hope you can help thanks again.
