5. FAQs
What is P.R.O C.A.M.E.R.A?
It's an automated block of JSON fields that adds professional camera realism, including optics, angles, motion, and film-grain, particularly useful for photorealistic prompts.
Are character presets used for products?
No, the subject_look block is only added for human characters. Product-focused prompts will skip this.
What if I don't add a voiceover script?
The JSON will still include the voiceover metadata (language, tone, etc.), allowing you to add the script later in your workflow.
