FAQs
Which is the best AI video model in 2026?+
There is no single best model. Veo 3 leads for cinematic ads with sound, Sora 2 for prompt adherence and multi-shot stories, Kling 2.0 for character motion, Seedance for product/motion + audio, Runway Gen-4 for editing workflows, and Luma/Pika for fast ideation. We pick per shot.
How much does an AI video model cost per second?+
Model compute typically costs ₹0.05–0.50 per second generated. A 15-second reel of raw compute is ₹3–8k, but final delivery includes storyboard, direction, character prep, sound design and post — which is why studio pricing runs ₹5k–15k per finished second.
Can AI video models generate audio too?+
Veo 3 and Seedance generate synchronized audio inline. Others (Kling, Runway, Luma, Pika) need audio layered in post — either licensed library music, custom sound design, or AI music/SFX tools like ElevenLabs and Suno.
Which model is best for character consistency?+
Runway Gen-4 with reference conditioning + Kling 2.0 for motion are the strongest for consistent characters across shots. For guaranteed likeness on real people, we always use image-to-video with locked reference frames instead of pure text-to-video.
