Potential Paths: Path 1: Utilize Runway since it directly offers text-to-video functionality, which is what the teacher is looking for. This application is user-friendly and doesn't require any special skills and caters directly to educators. Path 2: A combination of ElevenLabs to create voiceovers for the content based on text input and then use any basic video editing software to incorporate the voiceover into a visual presentation. This would create a pseudo text-to-video experience, but involves an extra step.

Final Narrative: For your need to create engaging audiovisual content based on text input, I recommend using Runway. It's an all-in-one platform for media creation and editing, with a specific feature that suits your need: Text to Video. This feature allows you to input text and Runway transforms it into a video clip. It's helpful for visualizing complex ideas in an understandable way.

Here's how Runway can provide a solution to your need:

• Text to Video: Convert your textual educational content into engaging video materials. The complexity of the topic does not matter, as Runway can simplify concepts with the help of visuals.
