Question 1

What are AI video generators?

Accepted Answer

AI video generators create video content from text prompts, images, or existing video clips. They can produce realistic footage, animations, and cinematic sequences. Leading models include Sora (OpenAI), Veo 3 (Google), Kling 2 (Kuaishou), and Runway Gen-4.

Question 2

Which is the best AI video generator in 2026?

Accepted Answer

Sora 2 and Veo 3 lead for photorealism and cinematic quality. Kling 2 excels at consistent character motion. Runway Gen-4 is the most versatile for creative and commercial video editing workflows. The best choice depends on your use case: long-form generation, style consistency, or editing speed.

Question 3

How long can AI-generated videos be?

Accepted Answer

Current AI video generators typically produce clips of 5–20 seconds per generation. Longer videos are created by stitching multiple clips together. Sora 2 can generate up to 60-second clips. For longer productions, tools like Runway provide a full editor for assembling AI-generated sequences.

Question 4

Can AI video generators use my own footage as input?

Accepted Answer

Yes. Most advanced video AI tools support video-to-video transformation — you upload a clip and the AI applies a style, modifies elements, or extends the footage. This is useful for visual effects, style transfer, background replacement, and upscaling older footage.

Question 5

Are AI-generated videos detectable?

Accepted Answer

AI video detection is an active research area. Current detectors can identify many AI-generated clips through artefacts in motion, hands, and fine details, but detection is not reliable enough for verification purposes. AI video quality is improving faster than detection methods.
