Kavel Blog FAQ

Answers for using the guides to get better prompts, references, and video drafts.

Start with the guide that matches your current problem: writing prompts, planning references, product clips, campaign concepts, motion control, or credit planning.

They help you plan the prompt, references, and output before you generate.

Use an example as a starting structure. Replace the subject, use case, audience, and visual references so the prompt gives you your own result.

Guides help you decide the goal, inputs, aspect ratio, camera direction, and quality level before you spend credits.

No. The guides are written around creation jobs like product clips, video references, concept previews, image references, and motion transfer.

Look for prompt patterns that define the hook, product moment, audience, platform format, and motion style. Then generate a few draft directions.

Focus on subject clarity, product shape, lighting, camera movement, and the page or campaign where the clip will run.

They help you write clearer prompts and choose the right settings before you generate, so there are usually fewer blind retries.

Yes. Kavel guides tie expectations to the options currently available, focusing on planning prompts, references, model choice, and credit use.
