Notable Tools

1. Runway: Reliable photorealistic output. Simple workflow, but limited custom controls.
2. Cling: Offers detailed control sliders — realism, camera, resolution. More customizable but slower rendering.
3. Luma: Stylized, surreal footage. Best for dreamy sequences, less ideal for humans.

Steps to Use Runway

1. Go to video generator.
2. Input a detailed prompt.
3. Choose model and length.
4. Click generate.
5. Review and refine outputs as needed.
