# When to leave the prompt blank in image to video tools

Image-to-video models already see your photo. A prompt should steer how it moves, not re-list every object in the frame.

# Leave it blank when

• The still already has a clear subject and you want gentle ambient motion
• You are testing crop and lighting first
• Extra words keep making the model invent objects that are not there

# Write a short prompt when

• You need a specific camera move (dolly in, orbit, locked tripod sway)
• Subject motion matters (hair in wind, steam rising, subtle smile)
• Environment cues help (soft rain, afternoon light) without contradicting the photo

# Prompt shape that usually works

Combine one camera note + one subject note. Example: “slow dolly in, soft fabric movement”. Avoid stacking ten style keywords.

# Tool note
