How to evaluate a switch
Three evaluation scenarios for this category. Each names the inputs, the required output and the measure.
Script to approved business video
Provide a short product script, style references, pronunciation notes and approved likeness permissions. Ask for a first cut and one factual revision. Record how much of the asset must be regenerated, how reviewers leave feedback and whether changes propagate consistently across formats.
Measure: accepted output, correction time, generation cost and rights traceability.
Localization without factual drift
Translate a finished explanation into two target languages and ask qualified human reviewers to assess meaning, pronunciation and visual consistency. Include a product name, a number and a claim that must not change. Measure localized acceptance rather than the number of languages advertised.
Measure: meaning preservation, correction burden and cost per accepted localized minute.
Interactive video with bounded actions
Where the product supports real-time interaction, introduce interruption, ambiguous identity and an action requiring approval. The presenter should acknowledge uncertainty and hand off appropriately. For a generation-only product, mark this scenario out of scope rather than treating missing live interaction as poor video quality.
Measure: latency, graceful interruption, correct handoff and authorization failures.
The evaluation owner should be the content producer or customer-experience designer. Use usable media and correctly completed audience tasks as the business target.

How should I evaluate a Synthesia alternative?

Can a reviewer approve a script and avatar separately, then lock both before localized versions are generated?
