```

**Processing Logic:**

def api_recreate_video(campaign_id):
    # Get new settings from request
    data = request.get_json() or {}
    new_language = data.get("video_language")
    new_duration = data.get("video_duration")
    new_script = data.get("script")

    # Update campaign settings if provided
    if new_language:
        campaign.video_language = new_language
    if new_duration:
        campaign.video_duration = int(new_duration)
    if new_script:
        campaign.script = new_script

    # Clear existing video data
    campaign.video_url = None
    campaign.video_id = None
    campaign.video_with_text_url = None
    campaign.status = "script_ready"

    # Generate new video with updated settings
