You may find the price fair for the features, but there are other costs. If you want to retry a generation, you might pay extra. Many users say retry options often fail because of throttling.

If you use the Plus plan, you might wait up to 8 minutes. Pro users get faster service, but you still wait. Relaxed Mode can take up to half an hour. These delays can break your creative flow. You may feel frustrated if you want to test many ideas quickly. Long queues are one of the main limitations of runway gen-4.5, especially for users who expect instant results.
User Satisfaction

- Some companies changed their tech stack to avoid these issues.
You need to weigh these points before you choose gen-4.5. If you want the best ai video quality and can handle some delays and costs, you may still find value. If you want a tool for quick, unlimited content, you might feel the limitations more.
