Looks promising! If you'd like to compare the performance between small, medium, and large models, you can look at the VTT files for the sqlite talk in the backstage area. I've also added support for tab-separated values (like Audacity label exports) and a subed-convert command to subed.el, which might give us a more concise format to work with.
