Feature 4: Multi-Shot Sequence Generation – Continuous Narrative with Visual Consistency

Core Capabilities Explained

Sora 2's multi-shot sequence feature can ensure:

  • Character Consistency – Same character maintains appearance across different shots
  • Scene Coherence – Unified environment, props, and lighting
  • Narrative Logic – Reasonable temporal and spatial relationships between shots
  • Style Uniformity – Consistent color tone, texture, and visual language

Sequence Generation Strategies

Method 1: Storyboard-Based Generation

def generate_multi_shot_sequence(shot_list):
    """
    Generate multi-shot sequence based on storyboard script
    """
    api_key = "your_apiyi_key"
    endpoint = "https://api.apiyi.com/v1/sora/sequence"

    payload = {
        "shots": shot_list,
        "maintain_consistency": {
            "characters": True,
            "environment": True,
            "lighting": True,
            "color_grade": True
        },
        "transition_style": "cut",  # cut/fade/dissolve
        "reference_image": "character_ref.jpg"  # Character reference image
    }

    headers = {
        "Authorization": f"Bearer {api_key}",
        "Content-Type": "application/json"
    }

    response = requests.post(endpoint, json=payload, headers=headers)
    return response.json()

# Usage example: Product introduction short film
shots = [
    {
        "shot_number": 1,
        "duration": 3,
        "prompt": "Wide shot: Modern office panorama, sunlight streaming through floor-to-ceiling windows",
        "camera": "wide_shot"
    },
    {
        "shot_number": 2,
        "duration": 4,
        "prompt": "Medium shot: Young designer working on laptop at desk",
        "camera": "medium_shot"
    },
    {
        "shot_number": 3,
        "duration": 3,
        "prompt": "Close-up: Design software interface on screen, mouse in operation",
        "camera": "close_up"
    },
    {
        "shot_number": 4,
        "duration": 4,
        "prompt": "Medium shot: Designer smiles with satisfaction, closes laptop",
        "camera": "medium_shot"
    }
]

result = generate_multi_shot_sequence(shots)
print(f"Sequence generation complete, total {len(result['shots'])} shots")

Method 2: Character Reference Image Binding

To ensure character consistency across different shots, you can provide reference images:

def create_character_consistent_shots(character_ref, scene_descriptions):
    """
    Generate consistent shots based on character reference image
    """
    api_key = "your_apiyi_key"
    endpoint = "https://api.apiyi.com/v1/sora/character-sequence"

    # Upload character reference image
    with open(character_ref, 'rb') as f:
        ref_data = f.read()

    files = {
        'character_reference': ('reference.jpg', ref_data, 'image/jpeg')
    }

    data = {
        "scenes": scene_descriptions,
        "character_consistency_weight": 0.9,  # 0-1, consistency weight
        "allow_costume_change": False  # Whether to allow costume changes
    }

    headers = {
        "Authorization": f"Bearer {api_key}"
    }

    response = requests.post(
        endpoint,
        files=files,
        data=data,
        headers=headers
    )

    return response.json()

Consistency Check and Correction

def check_sequence_consistency(video_urls):
    """
    Check consistency of multi-shot sequence
    """
    api_key = "your_apiyi_key"
    endpoint = "https://api.apiyi.com/v1/sora/consistency-check"

    payload = {
        "video_urls": video_urls,
        "check_items": [
            "character_appearance",
            "environment_match",
            "lighting_continuity",
            "color_consistency"
        ]
    }

    headers = {
        "Authorization": f"Bearer {api_key}",
        "Content-Type": "application/json"
    }

    response = requests.post(endpoint, json=payload, headers=headers)
    result = response.json()

    # If inconsistency found, can request correction
    if result["consistency_score"] < 0.85:
        print(f"Consistency score: {result['consistency_score']}")
        print(f"Problem shots: {result['inconsistent_shots']}")

Sora 2 视频生成功能的成本优化策略

分辨率与时长的成本权衡

分辨率 5秒成本 10秒成本 20秒成本 建议场景
480p ¥0.5 ¥1.0 ¥2.0 快速原型、内部测试
720p ¥1.2 ¥2.4 ¥4.8 社交媒体、在线广告
1080p ¥3.0 ¥6.0 ¥12.0 专业内容、品牌视频
4K ¥8.0 ¥16.0 ¥32.0 电视广告、影院内容

优化建议

策略 1: 分级生成

def cost_optimized_generation(prompt, quality_tier="social"):
    """
    根据用途选择合适的质量等级
    """
    quality_configs = {
        "prototype": {"resolution": "480p", "duration": 5},
        "social": {"resolution": "720p", "duration": 10},
        "professional": {"resolution": "1080p", "duration": 15},
        "broadcast": {"resolution": "4k", "duration": 30}
    }

    config = quality_configs[quality_tier]

    return generate_sora2_video(
        prompt=prompt,
        duration=config["duration"],
        resolution=config["resolution"]
    )

策略 2: 批量折扣利用

# 通过 API易平台批量提交享受折扣
def submit_batch_with_discount(video_requests):
    """
    批量提交任务享受折扣定价
    """
    api_key = "your_apiyi_key"

        "priority": "normal",  # normal/high
        "apply_discount": True
    }

    headers = {
        "Authorization": f"Bearer {api_key}",
        "Content-Type": "application/json"
    }

    response = requests.post(endpoint, json=payload, headers=headers)
    batch_info = response.json()

    print(f"原价: ¥{batch_info['original_cost']}")

常见问题与最佳实践

Q1: 如何确保多镜头序列的一致性?

A: 使用以下技巧:

  1. 提供角色或场景的参考图片
  2. 在提示词中明确描述需要保持一致的元素
  3. 使用 character_consistency_weight 参数加强一致性
  4. 先生成关键镜头,再基于关键镜头生成过渡镜头

Q2: 文本生成视频的提示词有字数限制吗?

A:

  • 单次提示词建议控制在 500 字符以内
  • 过长的提示词可能导致模型抓不住重点
  • 建议使用结构化的提示词格式,分层描述主体、动作、环境、风格

Q3: 生成的视频音效可以单独导出吗?

A: 可以。使用 separate_tracks: true 参数可以导出独立的音轨文件,支持后期重新混音。

Q4: Sora 2 支持生成多长的视频?

A:

  • 标准模式: 最长 20 秒
  • 扩展模式: 可通过视频扩展功能分段生成更长内容
  • 建议: 长视频采用分镜头生成后合并的方式

Q5: 如何选择合适的视觉风格?

A: 根据内容类型选择:

  • 商业广告: Cinematic(电影级)或 Commercial(广告级)
  • 教育内容: Clean(简洁)或 Explainer(说明性)
  • 艺术创作: 根据目标受众选择绘画风格或实验风格
  • 社交媒体: Trendy(潮流)或 Viral(病毒式)风格
