Questions about Gen-4.5
What is Gen-4.5?
Gen-4.5 is Runway’s video model from December 2025, focused on motion quality, prompt adherence and detail. It makes 5 or 10 second clips from text or a start image, and suits both realistic and stylized looks. Runway lists its known weak spots as cause and effect, objects that vanish and actions that succeed too easily
Does Gen-4.5 have sound?
Going by what Runway publishes, no: its model pages describe no sound or speech. Add voice and music separately, from a speech or music model on the same balance
How much does a Gen-4.5 clip cost?
Right now 5 seconds cost ₪2.8128.12 crGen-4.5, 5s and 10 seconds cost ₪5.6256.24 crGen-4.5, 10s. There is no resolution choice, and the output is HD, 1280x720 in landscape
Which aspect ratios does Gen-4.5 offer?
Starting from an image you can choose 16:9, 9:16, 4:3, 3:4, 1:1 or about 21:9. Runway says text only clips come out only in 16:9 or 9:16, so for another ratio start from an image
