How to Choose an AI Video Generator

Text-to-video is useful when composition can be discovered from the prompt. Image-to-video is better when a product, character, wardrobe, or first frame must remain recognizable. Video-to-video is the right category when motion or timing already exists and the goal is to restyle or transform it.

• Text only: fastest way to explore a scene
• Start image: stronger visual continuity
• Start and end frames: more control over the transition
• Source video: preserve motion while changing appearance

Check supported duration and resolution before evaluating style. A beautiful five-second result is not a substitute for a required 15- or 30-second shot. Native audio can reduce assembly work, but separate voice, music, and effects may offer more editorial control.

• Required aspect ratio and resolution
• Minimum and maximum clip length
• Native dialogue, sound effects, or music
• Generation speed and credit cost
• Reference-image and motion-control support

Write one prompt per intentional shot: subject, action, environment, camera, lighting, timing, and sound. Generate a draft at the lowest useful cost, review identity and motion, then spend on the delivery model only after the shot design works. Halo's catalog exposes these constraints before generation.

• Define the shot and success criteria
• Choose a model from required capabilities
• Draft and inspect continuity
• Generate the final delivery tier
• Save the result and reuse it as a reference
