El sistema de créditos de Runway explicado
10 credits for a 5-second video · 20 credits for 10 seconds
At 2 credits/second, Runway Gen-4 is the cheapest AI video model on our platform. A 5-second clip costs ~$0.10 — you can generate 100 videos for about $10. Compare that to Runway's own subscription ($12–76/month with limited generations) and it's a clear win on flexibility.

When it shines
Runway Gen-4 is the best choice when you need the cheapest per-video cost combined with excellent character consistency. At just 10 credits for a 5-second video, it's the most affordable way to produce AI video at scale. Its character consistency feature is genuinely best-in-class — the same person maintains their exact appearance across multiple shots, making it ideal for brand storytelling, multi-shot ads, and serialized content. The cinematic camera control (dolly, pan, crane) is also among the best.
When to pick a different model
If you need 1080p resolution, Runway's 720p output won't cut it — use Veo, Sora, or Kling instead. If speed is critical, Kling (~30s) and Wan (~20s) generate faster. If visual quality is your top priority regardless of cost, Veo 3.1 produces more photorealistic output. And for complex choreography or dance content, Seedance handles human motion better.
Limitations worth knowing
- 720p resolution (not 1080p). Runway Gen-4 outputs at 720p — lower than the 1080p offered by Veo, Sora, or Kling. For social media content this is usually fine, but for large screens or professional production, the quality difference is visible.
- 5–10 second maximum. Gen-4 clips max out at 10 seconds. For longer content, generate multiple clips and combine them — the character consistency feature helps maintain continuity across cuts.
- No audio generation. Unlike Veo 3.1 which auto-generates sound effects, Runway outputs silent video. You'll need to add audio separately in post-production.

Describe Camera Movement
Runway Gen-4 excels at camera work. Be specific about camera movement — dolly in, pan left, crane up, tracking shot. It understands cinematography terms.

Layer Your Prompts
Structure prompts in layers: subject → action → environment → camera → style. This gives Gen-4 clear priorities for each element.
