Question 1

What is an AI video generator?

Accepted Answer

An AI video generator synthesises short video clips from text prompts, still images, or storyboards using diffusion or transformer models. The category spans text-to-video, image-to-video, talking-avatar tools, and B-roll generators with varying clip length, resolution, and motion fidelity across platforms.

Question 2

How much does AI video generation cost?

Accepted Answer

Hobbyist plans run £12–25 per month with strict credit caps. Marketing-team tiers land between £40–120 per seat with frequent overage charges. Studio and enterprise plans with priority compute and high-resolution rendering reach £250–800 per month depending on output volume.

Question 3

Which AI video tool is best for marketing ads?

Accepted Answer

Pick a platform with strong motion coherence, image-to-video and camera-path control, and clear commercial licensing. Pure text-to-video without reference inputs rarely produces ad-grade output consistently — reproducibility across an ad set matters more than peak demo quality.

Question 4

Can AI video tools replace traditional video production?

Accepted Answer

AI wins on speed, iteration speed, and per-second cost for short-form social and B-roll content. Traditional production still wins on long-form narrative work, real talent performances, and brand-critical hero content. The practical stack is AI for volume and humans for hero pieces.

Question 5

Do AI video tools support lip-sync and talking avatars?

Accepted Answer

Yes — talking-avatar and lip-sync platforms drive realistic mouth movement from script audio, often with multilingual dubbing support. Quality varies on side-profile angles, fast speech, and emotional delivery, so test on your actual scripts and delivery style before committing to a licence.

Question 6

What are the licensing risks with AI video content?

Accepted Answer

Commercial-use rights vary significantly between platforms and tiers. Training-data provenance, indemnity clauses, and real-person likeness restrictions all carry legal risk in paid-media contexts. Always read the full licence terms before running AI-generated video in any advertising channel.
