VideoAgent: All-in-One Framework for Video Understanding and Editing
Abstract: Video editing has become essential in digital media creation, yet existing automated systems are restricted to short segment processing and domain-specific tasks. They face two critical limitations: i) inability to handle diverse video comprehension and editing operations, and ii) lack of long-video understanding for coherent narrative creation. We propose VideoAgent, an all-in-one agentic framework addressing these challenges through two key innovations. First, we develop automated video shot creation with shot planning agents for coherent narratives and cross-modal retrieval for aligned visual content. Second, we design a multi-agent orchestration framework integrating over thirty specialized editing agents. Intent parsing filters relevant tools while textual-gradient graph optimization assembles complex editing pipelines. Extensive experiments on our newly-proposed VideoEdit benchmark and public datasets demonstrate VideoAgent's superiority over existing multimodal LLMs and agentic systems. VideoAgent achieves 87-95% orchestration success rates while reducing API costs by 60%. Human evaluation across six video categories shows VideoAgent produces professional-quality content approaching human-level performance, with ratings only 4% below human-created videos. We release our code at https://github.com/HKUDS/VideoAgent.
Summary
- The paper presents a unified multi-agent framework that decomposes video editing into shot planning, semantic retrieval, and fine-grained trimming.

VideoAgent: A Unified Multi-Agent Framework for Automated Video Understanding and Editing
Introduction and Motivation
Automated video creation systems have consistently lagged behind the emergent demands of digital media workflows, primarily due to insufficient long-form comprehension and limited support for complex, multi-modal editing operations. The VideoAgent framework (2606.23327) directly addresses these deficiencies by introducing a highly modular, agentic architecture capable of end-to-end video understanding, shot planning, semantic retrieval, and compositional editing—scaling beyond short-form or domain-constrained automation.
Figure 1: Automated video editing with VideoAgent.
By uniting over thirty domain-specialized agents into a graph-optimized orchestration framework, VideoAgent demonstrates robust generalization for arbitrary production requirements. The system’s global-aware shot planning, cross-modal retrieval, and fine-grained control position it as a practical tool for video montage, rhythm-synced cuts, storytelling, meme adaptation, and more—all orchestrated through natural language instructions.
System Architecture and Technical Innovations
Automated Shot Planning and Visual Content Retrieval
VideoAgent’s core innovation is the hierarchical decomposition of editing instructions into shot-level narrative planning, followed by semantically aligned retrieval and subshot extraction. The shot planning agent leverages LLM-driven prompts and global context compression—built from content captions of all resource segments—to construct storyboarded sequences matching the user’s creative intent and available footage.
Figure 2: Automated video shot creation with shot planning, video retrieval and trimming.
Subsequently, cross-modal retrieval employs embedding-level alignment via ImageBind/CLIP to match shot descriptions to segment keyframes, maximizing both semantic consistency and retrieval efficiency. The fine-grained video trimming step further corrects temporal discrepancies, leveraging a VLM to select optimal sub-segments in accordance with narrative tempo and dialogue constraints.
Multi-Agent Graph Orchestration
To generalize across multi-modal editing tasks, VideoAgent structures its editing pipeline as a directed acyclic agent graph. The agent library encompasses basic preprocessing (audio extraction, normalization, beat detection), advanced manipulation (face swapping, lip sync, style transfer), and specialized creative logic (script adaptations, rhythm-aware montage, meme synthesis, etc.). All agents are dynamically selected and composed based on natural language intent parsing.
Figure 3: Video editing with agent graph orchestration and execution.
Unlike heuristic, single-pass orchestrators, VideoAgent optimizes the agent graph via iterative “textual gradient descent.” Here, the LLM receives a structured quality signal—enforcing acyclicity, connectivity, and intent coverage—and updates the graph via natural language-specified topology transformations. The process converges when both structural and semantic alignment objectives are satisfied.
Experimental Evaluation
Quantitative Benchmarks
VideoAgent outperforms a wide range of baselines across workflow orchestration, video retrieval, and segment alignment metrics, including specialized VLMs (Qwen2.5-VL, VideoMind), RAG-based multi-modal models, and agentic systems (GPTSwarm, GraphCounselor). On the VideoEdit and Shot2Story datasets, VideoAgent achieves orchestration success rates of 87-95%, often exceeding existing systems by 2–25% and delivering Recall@1 improvements of up to 18% over top commercial backbones.
Figure 4: Human-rated video quality assessment.
Critically, API costs are reduced by approximately 60%, attributable to the system’s early intent filtering and targeted subsegment inference, which contrast with the excessive token/context usage of “brute-force” multimodal LLM workflows.
Human Evaluations
In extensive human evaluation (26 participants, 49 video demos), VideoAgent maintains consistency, scene diversity, and audio quality ratings within 4% of professional human-crafted outputs—often surpassing baseline agents in reliability and production fitness.
Figure 5: VideoAgent ablation study results.
Ablation studies reveal that global-aware shot planning and gradient-driven graph optimization each provide major performance boosts; removal of either step degrades both success rates and qualitative metrics by substantial margins.
Generalization and Case Studies
On additional benchmarks such as VideoRepurpose and a variety of real-world scenarios (e.g., rhythm-synced montage, meme edits, cross-lingual adaptations), VideoAgent retains high retrieval and orchestration accuracy, validating the modularity and agentic scalability of its architectural design.

Practical and Theoretical Implications
Practically, VideoAgent offers significant reductions in both labor and cost for mass video post-production, live event summarization, and derivative content creation. Its flexible agent library and compositional pipeline enable direct application to beat-edited clips, AI-dub meme videos, cross-modal remixes, and domain-specific adaptations (e.g., stand-up, crosstalk narratives). The modular orchestration logic facilitates the integration of new generative agents (e.g., for data augmentation) and enables workflow refinement aligned with evolving editing conventions.
Theoretically, the textual-gradient graph optimization approach demonstrates that natural language can effectively guide symbolic search over combinatorial action spaces, with convergence grounded in explicit workflow correctness signals. This presents generalizable methods for graph-based agent coordination in other domains characterized by multi-stage, multi-modal tool use (e.g., scientific data pipelines, multi-agent simulation environments, or interactive storytelling systems).
Limitations and Future Work
While VideoAgent establishes a scalable, retrieval-centric paradigm, its performance is bounded by the diversity and quality of available source footage. Integration with generative video synthesis models could mitigate such constraints. Additionally, the power of automated editing demands ethical oversight—particularly to prevent the potential misuse of highly realistic content for misinformation or deepfake applications. Future work must focus on robust moderation frameworks and context-aware content validation.
Conclusion
VideoAgent represents a comprehensive leap in practical, editable video AI, bridging the usability and scope gaps of current multimodal agentic approaches. Through a unified framework that solves shot-level narrative planning, content retrieval, and graph-based compositional editing, it sets the technical foundation for next-generation automated media creation pipelines. The ability to combine robust quantitative gains with competitive human-level output quality demonstrates the viability of VLM-driven, multi-agent graph orchestration as a standard architecture for complex multimodal workflows.

Explaining “VideoAgent: All‑in‑One Framework for Video Understanding and Editing”
What is this paper about?
This paper introduces VideoAgent, an AI system that can plan, understand, and edit videos almost like a human video editor. It aims to turn everyday language instructions (like “make a fast-paced montage of basketball highlights synced to the beat”) into finished videos using a coordinated team of specialized AI tools.
1) Big picture: What’s the main purpose?
The main goal is to build a single system that:
- Understands long videos and the story a user wants,
- Plans a sequence of shots (like a director’s storyboard),
- Finds the right clips,
- Trims and arranges them to fit music or dialogue,
- And coordinates many editing tools to create a polished video.
In short, VideoAgent tries to make high-quality video editing possible for people who aren’t experts.
2) What questions does the paper try to answer?
The researchers focus on two key questions:
- How can an AI plan and create long, coherent videos (not just short clips) with a clear narrative?
- How can it coordinate many different editing tools (like subtitle generation, beat matching, voice-over, style transfer, face swap, etc.) in the right order without human help?
3) How does VideoAgent work? (Simple explanation)
Think of VideoAgent as a movie director with a big toolbox and a smart scheduler.
- “Director” part: It plans the story as a sequence of shots.
- “Toolbox” part: It includes 30+ specialized “agents” that do specific tasks (audio analysis, lip sync, voice generation, style filters, and more).
- “Scheduler” part: It figures out which tools to use and in what order to meet your goal.
Here are the main pieces:
Shot planning: Turning ideas into a storyboard
- The system looks at your instruction (e.g., “make a calm travel vlog with nature scenes and gentle music”).
- It also scans the available materials (video clips, audio tracks) and summarizes what’s in them.
- It then writes a shot-by-shot plan in plain language—similar to a storyboard: Shot 1, Shot 2, Shot 3… so the final video has a coherent flow.
Analogy: It’s like a chef reading your request (“a light, fresh dinner”), checking what’s in the pantry, and writing a course-by-course plan.
Finding the right clips: Matching words to visuals
- VideoAgent turns both the shot descriptions and video frames into “embeddings,” which you can think of as numeric fingerprints that capture meaning.
- It compares these fingerprints to find which clips best match each shot description.
- This is called cross‑modal retrieval: matching text (“a red car speeding through a tunnel”) to visuals (frames with a red car in a tunnel).
Analogy: It’s like searching your photos by typing “sunset beach” and your phone finds the right images.
Precise trimming: Fitting the rhythm and timing
- After choosing a clip for each shot, VideoAgent trims the exact moments to fit the target timing—like syncing a cut to a drumbeat or matching the length of narration.
- This step ensures the final video feels smooth and professional, not choppy or off-beat.
Analogy: Like a DJ lining up songs so the beats and transitions land perfectly.
Orchestrating many tools: Building and fixing the workflow graph
- VideoAgent contains 30+ tools (agents) for tasks like:
- Music beat detection
- Voice synthesis with different emotions
- Lip sync and face swapping
- Transcribing audio and adding subtitles
- Style transfer and visual effects
- Scriptwriting and content adaptation
- It first picks relevant tools based on your intent (intent parsing), then builds a “graph” (a flowchart) showing the order tools should run in.
- It improves this graph in rounds using a clever method the authors call “textual‑gradient graph optimization.” In simple terms:
- The system checks its own plan for problems (like steps in the wrong order or missing tools),
- Gets feedback in natural language (“this step depends on output from that step—swap them”),
- Then updates the plan and repeats until it’s solid.
Analogy: It’s like planning a road trip and adjusting your route after noticing detours or missing gas stations—each round makes the route better.
4) What did they find? Why does it matter?
The team tested VideoAgent on their new VideoEdit benchmark and other public datasets. Key results:
- High success at workflow orchestration:
- VideoAgent succeeded 87–95% of the time at building correct editing pipelines, beating other AI systems by 2–25%.
- Better video retrieval:
- It improved how well the system finds the right scenes for each shot across several base models (for example, Recall for GPT‑4o jumped from 31% to 49%).
- Lower cost:
- It cut API usage costs by about 60% thanks to smarter planning and targeted retrieval.
- Near human-level quality:
- In a human study across six video categories, videos made by VideoAgent were only 4% lower in quality than videos made by people.
- Reliable self-checking:
- When comparing AI evaluations to human judges, the system’s judgments aligned well (high accuracy and recall), suggesting it can reliably assess its own plans.
Why it matters:
- VideoAgent can help non-experts make professional-looking videos quickly.
- It scales to longer, story-driven content, not just short edits.
- It shows how many specialized AI tools can be coordinated effectively to do complex creative work.
5) What’s the impact and what comes next?
Impact:
- For creators: Faster production of trailers, vlogs, music videos, explainers, and more—without deep editing skills.
- For teams and studios: Automated pipelines that reduce time and cost, especially for routine editing tasks.
- For education and communication: Easier creation of clear, engaging video content from simple instructions.
Limitations and future directions:
- The system currently depends on the quality of available footage. If the right clips don’t exist, results are limited. Future versions could plug in generative video models to create missing shots.
- Like any powerful editing tool, there’s a risk of misuse (e.g., making misleading content). The authors encourage responsible use and content moderation.
Quick recap
- VideoAgent plans a story, finds the best clips, trims them to fit the rhythm, and coordinates 30+ editing tools to produce polished videos from plain language.
- It performs better than many existing systems, costs less to run, and gets close to human-level quality.
- It could make high-quality video creation accessible to many more people, while raising important questions about responsible use.
Knowledge Gaps
Below is a single, consolidated list of specific knowledge gaps, limitations, and open questions that remain unresolved by the paper. Each item highlights what is missing or uncertain and points to actionable directions for future work.
- [Objective/Optimization] The instruction–graph alignment loss is referenced but not formally defined or operationalized (metrics, normalization, supervision), leaving its computation, thresholds, and contribution to optimization unclear.
- [Convergence] No theoretical or empirical convergence guarantees for the “textual-gradient” graph optimization are provided; sensitivity to LLM non-determinism, prompt drift, and initialization remains unstudied.
- [Search Alternatives] The framework is not compared against principled discrete search/planning methods for workflow construction (e.g., MCTS, ILP, reinforcement learning over DAGs, evolutionary search), leaving open whether textual-gradient descent is optimal or efficient.
- [Scalability] The scalability of orchestration to much larger tool libraries (e.g., 100–300+ agents) and longer pipelines is untested; there is no complexity analysis of graph search time, memory, or cost as library size grows.
- [Typing/Interfaces] Edge compatibility is approximated via “shared capabilities” overlap; there is no formal, typed I/O schema or static type checking to guarantee data-format compatibility and prevent runtime mismatches across agents.
- [Capability Ontology] The capability mapping function Ψ for each agent appears hand-crafted; methods for automatically learning, verifying, and updating a capability ontology as tools evolve are not explored.
- [Failure Handling] The system lacks a documented error-handling and self-repair strategy when individual agents fail, produce malformed outputs, or violate constraints (e.g., automatic retries, substitutions, or graph repairs).
- [Resource-Aware Scheduling] Workflow optimization is agnostic to resource constraints (latency, GPU/CPU memory, monetary budgets); scheduling, parallelization, and budget-aware graph construction are not addressed.
- [Long-Video Scale] Despite “long-video” claims, the empirical evaluation does not test hour-scale projects end-to-end; memory, context management, and retrieval quality for multi-hour footage remain open.
- [Retrieval Temporal Semantics] Keyframe-based retrieval may miss temporal dynamics (actions, transitions) and identity continuity; integrating spatiotemporal encoders (e.g., video-language transformers, tracking/person re-ID) is left unexplored.
- [Audio-/Text-Conditioned Retrieval] Although inputs may include audio tracks and textual documents, retrieval is evaluated primarily on text–visual alignment; audio-conditioned or narration-conditioned retrieval quality is not studied.
- [Trimming Accuracy] The fine-grained trimming agent’s temporal precision is not benchmarked against objective synchronization metrics (e.g., beat-hit rate, phoneme/word-boundary alignment, edit-point accuracy).
- [Narrative Consistency] There is no mechanism or metric to enforce/evaluate narrative coherence across shots (character identity, lighting/color continuity, transitions, visual style consistency).
- [Hybrid Retrieve–Generate] The paper notes adding generative video models but does not propose decision policies for when to retrieve vs. generate, how to fuse both under budget/quality constraints, or how to keep visual continuity across modes.
- [Style-Conditioned Pacing] Shot-length decisions are rule/agent-driven but not learned from style exemplars or user preferences; learning pace/structure from references or editor feedback is an open direction.
- [Cost–Quality Trade-offs] While API costs are reduced, there is no systematic analysis of cost–quality–latency trade-offs, energy consumption, or how hyperparameters impact total cost at production scale.
- [Multilingual Robustness] Claims of cross-cultural/style transformations are not matched with multilingual evaluation (instructions, captions, scripts); cross-lingual retrieval and planning accuracy remains unquantified.
- [Safety/Moderation] Content moderation, harmful-edit detection, and provenance/watermarking (e.g., C2PA) are acknowledged but not implemented; concrete safeguards for deepfakes (face swap, lip-sync) are missing.
- [Copyright/Compliance] The system does not include license checking, source-media provenance verification, or fair-use-aware clip-length constraints to guide legally compliant outputs.
- [Privacy] There is no privacy-preserving design (on-device processing, encryption, access control, differential privacy) for user-supplied media processed by third-party models/APIs.
- [Reproducibility] Many agents appear to rely on proprietary APIs; reproducibility under model/version drift, availability, and rate limits is not addressed, nor are standardized fallbacks documented.
- [Benchmark Transparency] The new VideoEdit benchmark lacks detailed public documentation on task diversity, annotation protocols, release status, licenses, and bias assessment; replication and community comparability are limited.
- [LLM Judge Validity] Orchestration “success rate” partially relies on LLM judgments; the study uses small samples and does not report inter-annotator agreement, Cohen’s κ, or significance testing for human–LLM agreement.
- [Human Study Rigor] Human evaluation (26 raters, 18 videos) lacks details on blinding, randomization, cultural diversity of raters, and statistical significance tests; potential confounds (different source assets) are unaddressed.
- [Metric Coverage] Final video quality is not assessed with standard objective metrics (e.g., VMAF/SSIM for visuals, MOS-like measures for audio, rhythm sync scores), impeding reproducible comparisons.
- [Task Success Definition] “Success rate” for orchestration is not operationalized with precise task-level criteria; continuous quality grading of pipeline design (beyond binary success) is absent.
- [Interactive Editing] The system is fully automated; mechanisms for human-in-the-loop revision cycles, preference learning, and interactive constraint injection during graph optimization are not explored.
- [Large-Scale Indexing] The “compressed visual summary C” approach does not address scaling to millions of assets; vector-database indexing, incremental updates, and memory-bound retrieval policies are open.
- [Ambiguity Handling] There is no dialog-based disambiguation for underspecified or conflicting instructions, nor a policy for asking clarifying questions vs. making assumptions.
- [Explainability/Auditing] There is no user-facing provenance of decisions (why a clip was chosen, why an agent was inserted), nor audit logs for post-hoc analysis and compliance audits.
- [Type-Rich Compatibility] The edge-compatibility ratio χ based on shared capabilities may accept semantically invalid connections; richer data typing (modalities, sampling rates, codecs, sample formats) and static validation are needed.
- [Robustness to Domain Shift] Generalization to niche or highly specialized genres (e.g., sports analytics, scientific videos) is not tested; robustness under domain shift and low-resource settings remains unclear.
- [Hardware/Throughput] The system’s throughput, batching, and GPU/CPU utilization strategies are not characterized; real-time or near-real-time editing feasibility is unknown.

- Textual-gradient graph optimization: An optimization method that refines agent graphs using language-based gradient signals. "textual-gradient graph optimization assembles complex editing pipelines."
- Topological ordering: An ordering of nodes in a DAG such that all edges point forward, enabling valid execution sequences. "valid topological ordering"
- Vision LLMs (VLMs): Models that jointly process visual and textual inputs for tasks like understanding and editing. "Vision LLMs (VLMs)"
- Visual style transfer: Modifying the stylistic appearance of visuals while preserving content. "visual style transfer."
- Workflow orchestration: Designing and executing the sequence of tools/agents to accomplish an end-to-end task. "workflow orchestration with high-quality video creation instructions"
