Hi Jacob, and everyone else. We are soon to roll out tool that will read Avid project files/mxf-files and auto-transcribe them (individual or batches). The beta will launch in a week or two, and you can read about the apps on our site, http://www.edmon.ai . Once completed, our apps will allow for transcribing a batch of clips from a Media Composer bin, edit the parts you select (via text-editing), exporting an AAF that links to the original media in your Media Composer project. Let me know if you would be interested in trying it out (windows only, for now). We will soon add subtitle-export as well – which is really what you asked for I guess 🙂
