Is it possible to add a demo for an audio of 10 second without registering? Something that is small enough that does not break your server and that can not be used for something useful. My guess is that people don't want to register, even if it's free.
EDIT: The video in the main age does not have audio!!! Add some audio to it, that can be unmuted. (I hate autoplay with sound.)
EDIT2: Don't put a question in the title here unless you really want to make a question. The preferred style is something like "Twiso: Podcast to video tool" (I removed "to drive engagement, because I like a dry style in the titles.) Anyway, it was interesting so I forgot to complain about the title in the first comment.
