Batch convert Flash project to other format (HTML5 canvas) and export audio

Hey man, did you ever figure out how to have it automatic? Im speaking in regards to not haiving to click the "OK" button all the time

Hey reyco1, I think Adobe Animate CC already has an option to convert Flash content to HTML5 canvas.

On Adobe Animate CC, open your Flash project, then click "Commands" then click "Convert to other Document Formats" and that's how you can convert your Flash animation into HTML5 canvas.

You can execute fl.supressAlerts to stop Animate alerts. Hope that helps.
