Video Generation: Kling, Runway, Pika, Veo.
Master the four engines that turn storyboards into moving images.
After this lesson you'll know
- The strengths, weaknesses, and pricing of each major video generation platform
- How to use image-to-video workflows for maximum control
- Advanced prompting techniques specific to each platform
- How to select the right tool for each shot type
Platform Comparison Matrix
Each video generation platform has a distinct personality. Choosing the wrong one for a shot type wastes credits and time. | Feature | Kling 2.0 | Runway Gen-4 | Pika 2.0 | Google Veo 3 | |---------|-----------|-------------|----------|-------------| | Max duration | 10s | 10s | 8s | 16s | | Resolution | 1080p | 1080p | 1080p | 1080p/4K | | Camera control | Excellent | Good | Basic | Good | | Motion quality | Best | Excellent | Good | Excellent | | Character faces | Good | Excellent | Good | Very Good | | Physics | Good | Good | Fair | Very Good | | Cost per clip | $0.10-0.30 | $0.20-0.50 | $0.05-0.15 | $0.15-0.40 | | Image-to-video | Yes | Yes | Yes | Yes | | API access | Yes | Yes | Yes | Yes | | Best for | Action, motion | Cinematic beauty | Quick iteration | Long shots |
Use multiple platforms in the same project. Establishing shots might come from Veo (longer duration), character close-ups from Runway (best faces), and action sequences from Kling (best motion). The audience does not know or care which tool generated each shot.
Image-to-Video: The Control Workflow
Text-to-video is unpredictable. Image-to-video is controllable. Always prefer image-to-video when you have storyboard frames. The workflow: 1. Take your approved storyboard frame (from Lesson 3) 2. Upload it as the starting frame 3. Write a motion prompt describing only the movement 4. Generate and evaluate The critical distinction: your image prompt (from storyboarding) handled composition, lighting, character, and setting. Your video prompt handles only motion and camera movement. Separating these concerns gives you control over both independently. **Kling image-to-video prompt format:** ``` Camera slowly pushes in toward the subject. Rain continues falling. The woman slowly raises the photograph closer to her face. Her expression shifts from neutral to confused. Subtle movement in the background -- city lights flickering through rain-streaked window. Cinematic, 24fps. ``` **Runway Gen-4 image-to-video prompt format:** ``` Slow forward dolly. Subject lifts object with both hands. Facial expression transitions from calm to unsettled. Rain on window continues. Background lights shift slightly. Maintain shallow depth of field throughout. ``` Notice: the Kling prompt is more descriptive and narrative. Runway responds better to concise technical direction. Learning each platform's prompt dialect is essential.
Key technique: Never describe what is already in the image. The model can see it. Only describe what should CHANGE -- movement, expression shifts, camera motion. Redundant descriptions confuse the model and reduce quality.
