Planning a Multi-Shot AI Video in JSON (and Checking the Character Limits Before You Paste)

说明与用途

脚本验证每个镜头和总长度的字符限制，并检查连续性短语，确保 AI 视频输出一致。

问题

Managing per-shot and total character limits while ensuring continuity details in multi-shot AI video prompts.

结果

The script ensures each shot stays within 500 characters, the total stays within 1200, and continuity phrases are present, preventing visual inconsistencies.

工作流

• Create a JSON file with "continuity" array and "shots" array.
• Run the provided Python script: python check.py storyboard.json.
• Review script output: if "OK to paste" then proceed; otherwise fix reported issues.
• Paste validated prompts into the GPT Image 2.5 editor.
• Generate the video.
• Verify continuity visually.
• Iterate if necessary.

证据

Each @element token counts as 37 characters.

来源

The editor shows a per-shot counter (Shot 0/500) and a total counter (Total 0/1200).

来源

Delete "grey coat" from shot 2 and the script reports the missing continuity detail, which is exactly the kind of slip that produces a different-looking character halfway through.
