Gemini Video

Gemini Video Skill

Invoke Google Gemini models for video understanding, analysis, transcription, and content extraction using the Python google-genai SDK.

Available Models

Configuration

API Key: Use environment variable GEMINI_API_KEY

Usage

Video Analysis (Local File)

For local video files, use the File API to upload first:

python -c "
from google import genai
from google.genai import types
import time

client = genai.Client(api_key=os.environ.get('GEMINI_API_KEY'))

# Upload video file
video_file = client.files.upload(file='VIDEO_PATH')
print(f'Uploaded file: {video_file.name}')

# Wait for processing
while video_file.state.name == 'PROCESSING':
    print('Processing video...')
    time.sleep(5)
    video_file = client.files.get(name=video_file.name)

if video_file.state.name == 'FAILED':
    raise ValueError('Video processing failed')

# Analyze video
response = client.models.generate_content(
    model='gemini-3-pro-preview',
    contents=[
        types.Content(parts=[
            types.Part(text='Describe what happens in this video'),
            types.Part(file_data=types.FileData(file_uri=video_file.uri, mime_type=video_file.mime_type))
        ])
    ]
)
print(response.text)
"

Video Analysis (From URL)

python -c "
from google import genai
from google.genai import types

client = genai.Client(api_key=os.environ.get('GEMINI_API_KEY'))

# For publicly accessible video URLs
video_url = 'VIDEO_URL_HERE'

response = client.models.generate_content(
    model='gemini-3-pro-preview',
    contents=[
        types.Content(parts=[
            types.Part(text='Analyze this video and provide a detailed summary'),
            types.Part(file_data=types.FileData(file_uri=video_url, mime_type='video/mp4'))
        ])
    ]
)
print(response.text)

Video Transcription

python -c "
from google import genai
from google.genai import types
import time

client = genai.Client(api_key=os.environ.get('GEMINI_API_KEY'))

# Upload video
video_file = client.files.upload(file='VIDEO_PATH')
while video_file.state.name == 'PROCESSING':
    time.sleep(5)
    video_file = client.files.get(name=video_file.name)

# Transcribe
response = client.models.generate_content(
    model='gemini-3-pro-preview',
    contents=[
        types.Content(parts=[
            types.Part(text='Transcribe all spoken words in this video. Include timestamps if possible.'),
            types.Part(file_data=types.FileData(file_uri=video_file.uri, mime_type=video_file.mime_type))
        ])
    ]
)
print(response.text)

Workflow

When this skill is invoked:

1. Determine the task type:

   • Video Summary: Generate overview of video content
   • Transcription: Extract spoken words
   • Visual Analysis: Describe visual elements, scenes, actions
   • Content Extraction: Pull specific information from video
   • Q&A: Answer questions about video content

2. Prepare the video:

   • Local file → Upload via File API
   • Remote URL → Use directly (if publicly accessible)
   • Wait for processing if needed

3. Select the appropriate model:

   • Complex analysis → gemini-3-pro-preview
   • Quick summaries → gemini-2.5-flash

4. Execute and return results

File Management

List Uploaded Files

python -c "
from google import genai

client = genai.Client(api_key=os.environ.get('GEMINI_API_KEY'))

for f in client.files.list():
    print(f'{f.name}: {f.state.name} ({f.mime_type})')
"

Delete Uploaded File

python -c "

Supported Video Formats

• MP4 (video/mp4)
• MOV (video/quicktime)
• AVI (video/x-msvideo)
• FLV (video/x-flv)
• MKV (video/x-matroska)
• WebM (video/webm)
• WMV (video/x-ms-wmv)
• 3GPP (video/3gpp)

Video Limitations

• Maximum file size: Check current API limits (typically 2GB)
• Maximum duration: Varies by model (typically up to 1 hour)
• Processing time: Longer videos take more time to process
• Quota: Video analysis consumes more tokens than text

Error Handling

Common errors and solutions:

• PROCESSING state stuck: Video may be too large or corrupted
• FAILED state: Unsupported format or processing error
• File not found: Upload before analysis
• Rate limiting: Implement retry with exponential backoff

Notes

• Videos must be uploaded via File API before analysis (no inline data like images)
• Processing time depends on video length and complexity
• Uploaded files are automatically deleted after 48 hours
• For very long videos, consider chunking or asking specific timestamp questions
• Gemini 3 Pro provides the most detailed video analysis

Tools to Use

• Bash: Execute Python commands
• Read: Load local video file paths
• Write: Save transcriptions or analysis to files
• Glob: Find video files in directories
