Text-to-Video vs. Image-to-Video: Choose Your First Frame

The key distinction is the starting input. Text-to-video begins from a written prompt; image-to-video begins with an opening image and asks for motion. Neither is universally better. Choose based on how important the first composition is, then confirm the selected endpoint’s settings.

Text-to-video: describe a new opening scene

Use a written subject, setting and action when the first frame can be invented. Wan 3.0 Prime and Seedance 2.0 each have text-to-video endpoints. Their duration, resolution, aspect ratio and audio controls are endpoint-specific; read the selected route’s current values instead of assuming they match.

Image-to-video: anchor the first frame

Use a source still when a product, crop, artwork or approved composition should form the opening. Wan 3.0 Prime has a dedicated I2V endpoint requiring an opening image. Vidu Q3 Turbo is also documented as I2V, not T2V, and its notes describe 1–16-second clips with 540p/720p choices.

Write the prompt for the workflow

For T2V, describe the full scene and one main movement. For I2V, describe how the visible elements should move and what needs review. Do not ask an image-to-video model to reveal exact hidden surfaces that are absent from the starting frame.

Compare two routes fairly

If you test both, use a consistent shot concept and score framing, motion and detail separately. An image-to-video test necessarily includes a source still, so record it. One comparison supports a decision for that shot, not a universal model-ranking claim.

Check facts and generated details

Review face, text, logo, geometry, edges and temporal changes throughout the clip. A starting image does not guarantee those details remain pixel-identical. For product or documentary use, verify each factual claim against trusted source material.

Prompt or planning example

If the product’s opening crop and label placement matter, begin with an authorized still and try an I2V route with subtle motion. If the setting and composition are still open, test a T2V route with the same one-action brief.

Adapt this starting point to the source image, destination and controls shown in the selected route. Keep the original where relevant, then compare the result against the specific details named in your brief. If a detail is factual, verify it from a trusted source before using the image.
