Skip This If
When you need semantic or hierarchical tag structures, or when you require fine-grained programmatic control over which tag types are generated.
Integration Example
import requests
account_id = "YOUR_ACCOUNT_ID"
api_key = "YOUR_API_KEY"
location = "trial"
# Upload and index a video
url = f"https://api.videoindexer.ai/{location}/Accounts/{account_id}/Videos"
params = {"name": "my-video", "videoUrl": "https://example.com/video.mp4", "accessToken": api_key}

for label in result.json()["summarizedInsights"]["labels"]:
print(f"{label['name']}: {len(label['appearances'])} appearances")Gemini API (video understanding)
Google's Gemini models read a video's frames and audio and answer a prompt, so a tagging request can list your own tags and ask for JSON back. Google recommends Gemini as the replacement for its Video Intelligence API.
A tag vocabulary that lives in the prompt: change the list and re-run, with no model to train, and the model reads speech and on-screen text along with what it sees.
Strengths
- +Tags in your own words, or only from a tag list you put in the prompt
- +Hears the audio track as well as seeing the frames
- +About 100 tokens per second of video at the default media resolution, so input costs fractions of a cent per minute
- +The same call can describe, timestamp and answer questions about the clip
Limitations
- -Frames are sampled at 1 per second by default, so very brief events can fall between samples
- -Returns text with no per-tag confidence score unless you ask the model for one
- -Output depends on the prompt, so you validate tags against a labeled sample yourself
- -Videos go through the Files API upload and processing step before analysis
Real-World Use Cases
- •Tagging an ad library by product category, mood and call to action from one prompt
- •Labeling lecture or webinar recordings by topic for chapter navigation
- •Writing tags in a company's own vocabulary for a stock footage catalog
- •Replacing Video Intelligence API label detection before its 2027 shutdown
Choose This When
If your tags are your own business categories, and you can check the model's output against a labeled sample before trusting it.
Skip This If
When you need a calibrated confidence score per tag, frame-exact timing, or the same output for the same input every time.
Integration Example
from google import genai
import time
client = genai.Client()
myfile = client.files.upload(file="clip.mp4")

{"type": "video", "uri": myfile.uri, "mime_type": myfile.mime_type},
{"type": "text", "text": "Tag this clip using only these tags: product_demo, testimonial, "
"outdoor, indoor, logo_visible. Return JSON with each tag and the "
"seconds where it applies."},
],
)
print(interaction.output_text)Twelve Labs
Video understanding platform. Marengo 3.5 embeddings power search, and the Analyze API (Pegasus 1.6) answers a prompt about a video, which you can use to tag it in your own words with start and end times.
Video-native foundation models: Pegasus answers prompts about the whole video in temporal context, and Marengo embeddings let the same index serve search.
Strengths
- +Context-aware tagging understands actions and events
- +Natural language tag queries for custom concepts
- +Good temporal understanding of when tags apply
- +Simple API for quick integration
Limitations
- -Cloud-only with no self-hosting
- -Billed per hour of video indexed and analyzed, plus output tokens
- -No fixed tag vocabulary or taxonomy manager; tags come from your prompt
Real-World Use Cases
- •E-learning platforms tagging lecture videos with topics, demonstrations, and Q&A segments for chapter navigation
- •Ad tech companies classifying video ads by mood, product category, and call-to-action type for campaign analysis
- •Content platforms auto-generating chapter markers and topic labels for user-uploaded videos
- •News organizations tagging archive footage with events, people, and themes for rapid story research
Choose This When
If you want action- and event-aware tags from a natural-language prompt and also need video search over the same index.
Skip This If
When you need self-hosted processing, or a fixed label vocabulary with a confidence score per tag.

How do I automatically tag videos with AI?
Pick by where the tags come from. For a fixed vocabulary of objects, scenes and faces, send the video to a label API such as Amazon Rekognition Video or Azure AI Video Indexer. For tags in your own words, give a vision-language model such as Gemini or Twelve Labs Pegasus your tag list in the prompt. For tags that must match your own hierarchy and stay searchable, use taxonomy-based tagging such as Mixpeek's. Then check a labeled sample of your own videos before trusting any of them.
How much does AI video tagging cost per minute?
Checked October 13, 2026: Amazon Rekognition Video charges $0.10 a minute for label detection on stored video. Azure AI Video Indexer charges $0.045 to $0.15 a minute for video analysis, plus audio analysis billed separately. Gemini 3.5 Flash-Lite input costs about $0.0018 a minute of video at the default media resolution, before output tokens. Twelve Labs charges $2.50 per video hour to index and $1.75 per input hour for Pegasus analysis.
Is Google Video Intelligence API being shut down?
Yes. Google deprecated the Video Intelligence API on September 14, 2026 and will shut it down on September 14, 2027, and recommends migrating to Gemini models. Existing integrations keep working until then.
What is AI video tagging?
AI video tagging automatically assigns descriptive labels to video content using machine learning models. Tags can describe objects, scenes, actions, people, brands, and concepts visible or audible in the video. Unlike manual tagging, AI can process thousands of hours of video and generate consistent, comprehensive tags.
How granular can AI video tags be?
Modern tools tag at multiple granularity levels: entire video, individual scenes or shots, and specific frames. Scene-level tagging is most useful for search, as it allows users to find specific moments. Frame-level tagging is useful for detailed analysis but generates more data. Most platforms let you configure the granularity.
Can I create custom video tag categories for my industry?
Yes. Mixpeek matches each segment against your own taxonomy, Gemini and Twelve Labs tag from a prompt that lists your tags, and Roboflow and Datature train detectors on frames you label. Amazon Rekognition supports custom labels through its separate Custom Labels service.
