Generate an AI-powered description of a specific video frame’s visual content. 
import videodb

conn = videodb.connect(api_key="your_api_key")
coll = conn.get_collection()
video = coll.get_videos()[0]

# Get scene collection
scene_collection = video.get_scene_collection("scene_collection_id")

# Get a frame from a scene
scene = scene_collection.scenes[0]
frame = scene.frames[0]

# Describe the frame
description = frame.describe()

print(f"Frame description: {description}")
print(f"Frame time: {frame.frame_time}s")

# Describe with custom prompt
custom_desc = frame.describe(prompt="List all objects visible")
  • Generates detailed visual description using AI vision models
  • Can use custom prompts to focus description on specific aspects
  • Overwrites existing frame description
  • Frame IDs start with fr- prefix
  • Each frame includes timestamp (frame_time) in the video
  • Useful for generating captions or accessibility descriptions
