Question 1

How do I pick the right AI video model?

Accepted Answer

Match the model to the shot. Dialogue / narration → Veo 3.1. 4K master / commercial → Kling 3.0 Pro. Music video / multimodal references → Seedance 2.0. Action / sports / dance → Hailuo 2.3. Image-to-video from a still → any of the above with reference image.

Question 2

When should I use Veo 3.1?

Accepted Answer

Dialogue scenes, broadcast-grade audio, cinematic 1080p, fast iteration (~4.2s gen time). Strongest in 2026 for any shot where talk tracks matter. See /veo-3-1.

Question 3

When should I use Kling 3.0 Pro?

Accepted Answer

4K masters, multi-shot storyboards, longest clip duration (60+ seconds with stitching), lowest cost per second (~$0.029). Best for commercials and bulk short-form. See /kling-3-0-pro.

Question 4

When should I use Seedance 2.0?

Accepted Answer

Multimodal reference generation (9 images + 3 videos + 3 audio per generation), beat-sync motion locked to a reference audio track, music videos. See /seedance-2-0.

Question 5

When should I use Hailuo 2.3?

Accepted Answer

Action scenes, sports, parkour, dance, expressive character motion. Strongest dynamic-motion model in the 2026 lineup. See /hailuo-2-3.

Question 6

Should I just let the agent pick?

Accepted Answer

Often yes — Agent mode reads the brief and routes to the right model per shot. Manual mode is for when you have a strong opinion. See /agent-mode, /manual-mode.

Question 7

Where can I compare models head-to-head?

Accepted Answer

/veo-vs-kling, /seedance-vs-kling, /veo-vs-seedance, /kling-vs-hailuo, /seedance-vs-hailuo. Or pick by tier: /seedance-2-0-vs-fast, /kling-2-6-vs-3-0-pro.
