Consistent characters across scenes
The #1 question in AI video: keep the same person looking identical in every shot. Here's the workflow — built into 7stories.
Generic text-to-video changes the subject between shots. The fix is a two-step pipeline: create a consistent character image first, then turn it into video. Two image engines are specifically great at character consistency: Nano Banana (Gemini 2.5 Flash) and Seedream 4.5.
The workflow
- Upload one clear photo of your subject in step 6. Face the camera, good light, full head and shoulders.
- Pick Nano Banana or Seedream as the image engine (step 8).
- Choose + Video or Both in step 7, and a video engine (step 9) — Veo, Kling, or Sora all work well.
- Describe the scene in step 5, keeping the same person's identity in the words ("the same young woman…").
- Generate. Because the reference photo anchors the subject, the image and the video's opening frame share the same face.
💡 Why this works
Nano Banana and Seedream are trained to hold a subject's identity when given a reference. Using that image as the video's start frame carries the identity into the film.
Tips for consistency
- Use one clear, high-resolution reference photo — not a group shot.
- Keep hair, clothing, and setting described the same way across scenes.
- For a multi-scene reel, generate one image per scene from the same reference, then animate each.
