Depends on the tool. Sora 2 takes 5-15 minutes for a 10-second clip at 1080p. Runway Gen-4 takes 60-90 seconds. Pika 2.0 takes 30-60 seconds. Hailuo takes 2-3 minutes. For daily TikTok content, fast iteration matters more than 4K quality. I use Pika for daily work, Runway for client work.
Yes, paid plans grant commercial usage rights including social media monetization. Free tiers may restrict commercial use. I publish TikTok videos made with Runway and Pika and monetize them. Check each tool terms before posting to YouTube or TikTok with ads.
I tracked 100 video generations. Runway Gen-4 at $95/mo: ~$1.20 per 10-second clip. Pika 2.0 at $8/mo: ~$0.04 per clip. Sora 2 in ChatGPT Plus at $20/mo: effectively free (limited generations per day). Hailuo free tier: free with daily cap. The cheapest per-clip is Pika, but quality is lower.
Video AI is harder than image AI. Common issues: morphing faces (use reference images), inconsistent characters (use character consistency features), low motion (increase motion parameter), flickering (lower frame rate). For best results, generate 3-5 second clips and stitch in a video editor rather than asking for a full 30-second video.
I've been testing and reviewing AI tools for 2+ years. I run saas.pet as a side project while working as a software engineer. I buy every subscription I review. No vendor pitches, no free accounts. If a tool is in my rotation, I pay for it.
