About this tool
Sora is OpenAI's text-to-video model, and unlike image generators such as Midjourney, there's no widely published hard character limit for its prompts. The bigger consideration is craft: video prompts benefit from clearly describing the scene, subject, motion and camera direction rather than just a list of adjectives.
This counter still tracks your character, word and estimated token count as you draft, and the guidance panel offers general recommendations for keeping a video prompt focused.
If you're moving between text-to-image and text-to-video prompting, remember that motion and camera-direction language (“slow dolly in,” “handheld tracking shot”) does real work in a video prompt in a way it doesn't for a static image.
Frequently asked questions
What is the character limit for Sora prompts?
OpenAI has not published an official hard character limit for Sora prompts as of this writing. Focus on clarity and specific scene/motion/camera detail rather than length.
What should a good Sora prompt include?
Strong video prompts typically describe the subject, setting, specific motion, and camera behavior (e.g., pan, dolly, handheld) rather than just static visual adjectives.
