Hi,
In Magix Movie Studio 2024 Platinum or Suite or Video Pro X15, if you do not have a subscription, you can at least view the Text-to-Speech tool - with languages and speakers, and the Stock Content that is available. Of course, you cannot use the Text-to-Speech tool or download any of the content without a subscription, but at least you can see what it's all about before deciding whether or not to go the subscription route in the future.
Under the MAGIX Hub tab, select My Profile. Log in using your normal Magix account username (email)/password. After that, you will have access to the Text-to-Speech and Content windows.
Video content
Audio content
Note the messages on the above screens stating that "You don't have a valid subscription..."
