Image-to-video vs text-to-video: which one should you use?

The short answer

• Use image-to-video when something must look exactly like a specific picture: a product, a character, a brand asset, a piece of artwork.
• Use text-to-video when you are exploring ideas or need generic footage that does not have to match anything.

How each one works

Text-to-video builds every part of the scene from the prompt: subject, setting, light, style and motion. You get the most creative freedom, and the least control over specifics.

Image-to-video treats your image as the first frame or visual anchor. The prompt only describes what changes. You get more predictable results, but the output is limited by the quality and composition of the image.

Side-by-side

• Control over appearance: high with image-to-video, low with text-to-video.
• Creative range: narrower with image-to-video, wider with text-to-video.
• Prompt length: short for image-to-video (motion and constraints), longer for text-to-video (whole scene).
• Consistency with a brand or product: much better with image-to-video.
• Best for exploring a new idea: text-to-video.

Which to choose by task

• Product videos and ads: image-to-video, starting from a real photo.
• Animating artwork, posters or illustrations: image-to-video.
• Atmospheric b-roll such as landscapes or city scenes: text-to-video.
• Early concept testing for an ad idea: text-to-video, then refine with images.
• Social clips where the look does not have to match a specific asset: either one.

Combine them

A practical workflow is to explore with text-to-video until you find a look you like, take a strong still frame or generate an image of it, then use image-to-video to add controlled motion. You get the freedom of text and the consistency of an anchor image.

Mistakes to avoid

• Expecting text-to-video to reproduce an exact product or logo.
• Writing a long scene description for an image-to-video prompt. The image already provides it.
• Using a low-quality image and blaming the model for soft results.
