Quick take
Runway's flagship developer video model for text- and image-guided clips, with professional formats and a predictable credit-per-second base rate.
Format surcharges can exceed the base generation cost, and the provider does not publish one render-time number across settings.
Alibaba's unified video family for creating short clips with sound from text, a starting image, or a reference video.
The endpoints, accepted references, and defaults are not identical. Check watermark settings, content rules, live per-second pricing, and continuity across each shot before planning a campaign.
