תקציר מקורי באנגליתIn this tutorial, we build a runnable reconstruction of the VideoAgent workflow, focusing on the core agentic pipeline behind video understanding, retrieval, editing, and remaking. We start by configuring a lightweight environment that works without API keys. We define an intent parser, an agent library, a tool router, a graph planner, and a textual-gradient optimizer that repairs missing dependencies in the execution graph. We also connect these planning components to practical video-processing tools, including FFmpeg, Whisper-based transcription, scene detection, keyframe sampling, captioning, cross-modal indexing, retrieval, trimming, beat-synced editing, and final rendering. By the end of the tutorial, we have a complete multi-agent video system that can answer questions about a video,
