Frequently Asked Questions

Which AI video model is the best in 2026?
It depends on the job. Sora 2 is the cheapest per second of generated video and is strongest for faceless product ads. Veo 3.1 leads on face consistency across scenes and ships with native audio. Kling 3.0 leads on motion quality and smooth camera movement. Seedance 2.0 supports both text-to-video and image-to-video with cinematic realism.
Which AI video model is cheapest?
Sora 2 is the cheapest per second of generated video at standard quality. For a 3-scene 24-second ad, Sora 2 costs 54 credits versus 120 for Veo 3.1, 120 for Kling 3.0, and 108 for Seedance 2.0.
How much does Sora 2 cost?
18 credits for a standard 8-second scene, 65 credits for HQ. Sora 2 scales linearly with duration.
How much does Veo 3.1 cost?
40 credits per scene at standard quality, 130 credits per scene at HQ. Veo 3.1 is fixed-cost — the price stays the same regardless of scene duration. It is the only engine on the platform that renders native audio from dialogue in the same step.
How much does Kling 3.0 cost?
32 credits at standard for a 6.4-second scene, 50 credits HQ. Kling 3.0 is image-to-video only.
How much does Seedance 2.0 cost?
18 credits at standard for a 4-second scene, 35 credits HQ. Seedance 2.0 supports both text-to-video and image-to-video paths.
Which AI video model is best for TikTok ads?
For faceless TikTok product ads where on-screen text and product labels matter, Sora 2 is the strongest pick — lowest cost per second and accurate text rendering. For creator-led TikTok content where a face needs to stay consistent across hook, body, and CTA, Veo 3.1 with its reference-photo pipeline is stronger.
Can I use multiple AI video models in one project?
Yes. UGC Copilot lets you switch the render engine on a per-scene basis inside a single project, so you can pair (for example) Veo 3.1 for the creator hook with Sora 2 for the faceless product reveal in the same ad.
Which AI video model supports text-to-video without an input image?
Sora 2 and Seedance 2.0 both support text-to-video. Kling 3.0 is image-to-video only. Veo 3.1 is primarily image-driven (using a reference photo for face consistency).
How long does each AI video model take to render?
At standard quality: Veo 3.1 about 3 minutes per scene (3 in parallel); Sora 2 about 3 minutes per scene (chained one at a time); Kling 3.0 about 3 minutes per scene (3 in parallel); Seedance 2.0 about 4 minutes per scene (2 in parallel).
