Kling

Kling surprised us. It produces sharp, high-resolution footage with convincing human motion, and it allows some of the longest single-shot durations available.

The interface is less polished than Runway and the English prompt handling is occasionally literal, but for the price the output quality is remarkable.

If you are producing a high volume of clips and cost matters, Kling gives you the most footage-per-dollar without a big drop in quality.
