Bottom line

Decision questions

What teams ask before choosing

Can Opus Clip make a video from text?

Opus Clip is built around source-video repurposing. A text-to-video or avatar workflow begins with a reviewed script and a different production process.

Can Synthesia create short social clips?

It can produce a script-led video asset, but the team should decide whether a presenter format is the best creative choice or whether short excerpts from authentic source footage better fit the channel and audience.

What should be measured after publishing?

Measure the outcome tied to the distribution or campaign objective, not only a generic view count. Keep the source, creative format, audience, offer, and measurement window visible in the review.
