Video Summarization Workflows

Summarize long-form video content that exceeds standard VLM context limits. Requires the LVS profile — deploy with the deploy skill (-p lvs).

Overview

Use this skill when asked to summarize extended recordings, analyze activity during full shifts (such as a night shift), or compile daily narrative activity summaries.

Common triggers:

• "Summarize this video"
• "Generate a shift summary"
• "What happened during the night shift?"
• "Create a daily activity report"

Prerequisites

• LVS Profile Deployed: Ensure that the LVS profile is running (vss-sop-deploy with -p lvs).
• Video Storage Ingest: Target videos must first be uploaded/stored in VIOS before the agent can request a summary.

Instructions

1. High-Level LVS Pipeline

Long-form video processing is orchestrated across several steps:

1. Segment: The video is partitioned into smaller, digestible chunks.
2. Analyze: Each segment chunk is sent to the VLM independently.
3. Synthesize: Chunk analysis summaries are aggregated by the LLM.
4. Report: A final, cohesive narrative report containing timestamped highlights is output.

2. Execution via REST API

Upload files using VIOS storage APIs, then invoke the VSS Agent /generate endpoint with the summarization command.

Examples

Upload Video & Summarize

# Step 1: Upload a video via VIOS Storage API
curl -s -X PUT http://localhost:30888/vst/api/v1/storage/file/night-shift-entrance.mp4 \
  --upload-file /path/to/video.mp4 | jq .

# Step 2: Request the VSS Agent to summarize
curl -s -X POST http://localhost:8000/generate \
  -H "Content-Type: application/json" \
  -d '{"input_message": "Generate a summary report for night-shift-entrance.mp4"}' | jq .

Camera / Time-bounded Summaries

Summarize for a Specific Sensor:

curl -s -X POST http://localhost:8000/generate \
  -H "Content-Type: application/json" \
  -d '{"input_message": "Can you generate a summary report for sensor_0?"}' | jq .
