Which AI video tool should I actually use, and for what job?
Start with Google Flow, which runs Google's Veo 3.1 Lite and Gemini Omni Flash models and is the most genuinely free: every Google account gets 50 credits a day, enough for five 8-second Veo clips at 720p, though without a subscription video can be unavailable from 2 to 5 pm UTC, which is evening in India. Google AI Plus at ₹399 a month adds 200 credits and AI Pro at ₹1,950 adds 1,000. Runway is the best single studio, with its own Gen-4.5 beside Kling 4.0 and Seedance 2.5: 125 one-time free credits, then Standard at $12 a month billed yearly for 625 credits, about 52 seconds of Gen-4.5. Adobe Firefly gives free daily video generations from models trained on licensed content, the safe pick for client work. Pika's free plan has no monthly credits, Luma starts at $30 a month, and Sora is closed. Rule: test the idea free in Flow, and pay for Runway once you want several models in one place.
Google's own page on what is free: 50 Flow credits a day for every account, 10 credits for an 8-second Veo 3.1 Lite clip, the peak-hour limit for non-subscribers, and the extra credits each Google AI plan adds.
A month of hands-on testing that picks Google Veo for reliable results, Runway for film-making and Firefly for commercially safe output, and separates generators from editors and avatar tools.
Runway's plans: Free with 125 one-time credits, Standard $12 a month billed yearly (625 credits, 52 seconds of Gen-4.5), Pro $28, and the credit cost of Gen-4.5, Aleph 2.0, Kling 4.0 and Seedance in one account.
Adobe's generator, with a free plan of daily generations across video, image and audio, models it calls commercially safe because they are trained on licensed Adobe Stock and public-domain content, and partner models from Runway, Kling and Luma.
Luma's studio for brand work starts at Plus, $30 a month for 10,000 credits with commercial use, and lists the credit cost of Ray3.2 and Seedance by resolution.
