Run the same task in both

Prepare a 45-second product explanation with a corrected name, captions and a second-language version. Hold the inputs and acceptance criteria constant, and record the plan you used.

  • Use the same script and reference assets in every trial.
  • Correct one sentence after the first export and measure the work needed.
  • Review captions, pronunciation and subject consistency on a phone.
  • Calculate the cost of accepted outputs, including rejected generations.

How to reach a decision

Give the most weight to editing control, output quality. Record what you observed rather than treating a long feature list as a result. If neither tool passes your mandatory requirements, keep looking.

Calculate the effective cost per finished video minute after configuration time and any required add-ons. A successful trial is a workflow your team can repeat and maintain.
