the verdictFAIR · middle third for this operation
the catchDuration menu: the Runway help article 'Creating with Gen-4.5' lists 5s and 10s, but that page blocks direct reading (HTTP 403) and was only seen through the search index, so max_seconds is the softest number in this entry. The API guide says most models generate up to 30 seconds. Professional formats (ProRes, PNG sequence) add 5 credits/second; HDR adds 20.
