All videos generated in the Sora app are 8 seconds long 12 seconds long. This duration is fixed and perfect for TikTok hooks and looping content. If you need longer videos, you can generate multiple 8-second clips and stitch them together in editing apps like CapCut to create sequences up to 24 seconds or more.

Yes, the Sora app is currently invite-only and only available in the United States and Canada on iOS. You can request an invite code through the app, receive one from a friend who already has access, or check your ChatGPT account for a direct invite. ChatGPT Pro subscribers may have priority access.

A good prompt follows the 8-part template: Hook (first 3 seconds), Visual Style, Subject & Setting, Camera Work, Lighting, Action/Timing, Sound Design, and Mood. Be specific with details like “close-up of dancer in streetwear executing sharp move in neon-lit alley” rather than vague descriptions like “person dancing.” The more specific your details, the better your results.

If your video feels slow or boring, the issue is usually the hook. TikTok users scroll fast—you must grab attention in the first 3 seconds with movement, emotion, or something unexpected. Avoid starting with slow establishing shots. Add time markers to your prompt like “At 00:02, person spins suddenly” to create dynamic pacing.

Yes, but you must follow platform guidelines. All Sora 2 videos include a visible AI-generated watermark and C2PA Content Credentials. If your video promotes a brand, product, or service, you must turn on TikTok’s Commercial Content Disclosure setting. Avoid using copyrighted characters or music, and always obtain consent when featuring real people.
