V-ReasonBench: Toward Unified Reasoning Benchmark Suite for Video Generation Models
Abstract: Recent progress in generative video models, such as Veo-3, has shown surprising zero-shot reasoning abilities, creating a growing need for systematic and reliable evaluation. We introduce V-ReasonBench, a benchmark designed to assess video reasoning across four key dimensions: structured problem-solving, spatial cognition, pattern-based inference, and physical dynamics. The benchmark is built from both synthetic and real-world image sequences and provides a diverse set of answer-verifiable tasks that are reproducible, scalable, and unambiguous. Evaluations of six state-of-the-art video models reveal clear dimension-wise differences, with strong variation in structured, spatial, pattern-based, and physical reasoning. We further compare video models with strong image models, analyze common hallucination behaviors, and study how video duration affects Chain-of-Frames reasoning. Overall, V-ReasonBench offers a unified and reproducible framework for measuring video reasoning and aims to support the development of models with more reliable, human-aligned reasoning skills.

V-ReasonBench: A Unified Suite for Evaluating Video Generation Model Reasoning
Motivation and Problem Formulation
Advances in generative video models—such as Sora-2, Veo-3.1, Kling-2.5-Turbo-Pro, and Seedance-1.0-Lite—have demonstrated emergent zero-shot reasoning abilities, yet systematic evaluation of these capabilities remains fragmented. V-ReasonBench addresses this by introducing a unified, reproducible benchmark for large-scale assessment of reasoning abilities, structured into four core dimensions: structured problem-solving, spatial cognition, pattern-based inference, and physical dynamics. The benchmark is designed around the Chain-of-Frame (CoF) paradigm, which analogizes temporal video frame sequences to the stepwise logical trajectories in chain-of-thought prompting for LLMs, enabling reasoning traceability and efficient last-frame evaluation.

Benchmark Design and Task Taxonomy
V-ReasonBench employs an image-pair framework, with each task instance defined by an initial state/image, an explicit instruction, and a target answer state in the final frame. Evaluation focuses on the final frame, mitigating annotation complexity and emphasizing reasoning outcome. Tasks are programmatically generated for high coverage and diversity, spanning the following dimensions:
- Structured Problem-Solving: Arithmetic operations, code execution (simulated via Python), Sudoku completion, and adversarial planning in Tic-Tac-Toe.
- Spatial Cognition: Shape fitting challenges, visual symmetry completion, and color connection pathfinding tasks.
- Pattern-based Inference: Visual sequence completion, analogy-solving (“A:B::C:?”, demanding abstract mapping), and rule following from examples.
- Physical Dynamics: Block sliding (intuitive physics), communicating vessel equilibrium (hydrostatics), and temperature-induced deformation.
Mask-based, grid-based, and VLM-based scoring methods are selectively employed, with pass@k as the unified evaluation metric.

Evaluation Methodology and Reliability
Evaluation methods leverage deterministic, last-frame scoring using task-appropriate criteria:
- Mask-based: Used for localized object-centric tasks (e.g., block sliding) offering pixel-level fidelity checks.
- Grid-based: Applied on tasks with spatial grid structures (e.g., Sudoku, symmetry) focusing on cell-wise exactness.
- VLM-based: Reserved for visual tasks with reliable region extraction (e.g., arithmetic, code execution), employing Gemini-2.5-Pro as judge.
Benchmark-human alignment validation demonstrates consistently high decision agreement (97.09%) on binary pass/unpass judgments, ensuring robust interpretability.

A recurring limitation is observed in VLM-based evaluation—VLMs are unreliable in dense grid or fine-detail recognition scenarios, leading to false negatives even on structurally simple tasks, as the model automates symbolic outputs but struggles with subtle visual cues.

Empirical Results and Analysis
Across six commercial and research video models, Sora-2 and Hailuo-02 display strongest mean pass@5 scores, particularly in structured problem-solving and spatial cognition. Physical dynamics tasks (block sliding, equilibrium prediction) present lower performance across all models, exposing transfer limitations from abstract domains to physical simulation. Notably, the models display pronounced variation among reasoning types—structured and pattern-based reasoning success does not guarantee physical dynamics proficiency, underscoring inadequate incorporation of physics priors in generative architectures.
Reasoning Patterns, Chain-of-Frames, and Temporal Hallucination
Models exhibit a tendency for creative visual enrichment at the expense of structural accuracy, frequently altering minimalistic scenes (e.g., Tic-Tac-Toe) with extraneous artistic or contextual elements, thereby reducing evaluation scores for tasks demanding strict symbolic fidelity.
Figure 5: Seedance-1.0-Lite on symmetry—fills mirrored axis with decorations instead of faithful geometric reflection.
Temporal rollouts via CoF do not consistently improve reasoning accuracy with longer durations; extended sequences often inject irrelevant content and amplify hallucinations, suggesting that frame budget and context window must be tightly managed.
Figure 6: Sora-2 performance—longer CoF durations fail to enhance correctness in Sudoku/Rule Following.
Hallucinations frequently manifest as "right answer, wrong process," where intermediate frames diverge from physical reality (e.g., object passing through walls), yet the terminal state is correct, revealing the need for process-aware as well as outcome-aware evaluation.

Video vs. Image Models: Temporal Reasoning Impact
Veo-3.1 outperforms NanoBanana on causal/temporal tasks by leveraging frame-wise simulation, whereas NanoBanana excels in static, text-oriented or pure symbolic reasoning. This highlights the necessity of explicit temporal modeling for tasks encoding process-oriented reasoning versus static mapping.

Implications and Future Directions
V-ReasonBench sets a precedent for reproducible, reasoning-centric evaluation in generative video models, revealing that current models excel variably across cognitive domains and suffer from persistent hallucination/structural deviation issues. These insights encourage:
- Architecture enhancements for explicit physical prior integration.
- Development of hybrid evaluation routines combining endpoint and process assessment for temporally sensitive reasoning.
- Benchmark expansion toward causal inference, longer-horizon prediction, and real-world video understanding.
- Tuning of data curation to balance creative visual content with symbolic and structural fidelity.
Conclusion
V-ReasonBench formalizes a scalable methodology for multidimensional reasoning evaluation in generative video models, exposing systematic strengths and deficiencies across architectures. The benchmark facilitates precise, human-aligned measurement and highlights the need for principled integration of process fidelity, physical priors, and temporal reasoning in future video foundation models.

What is this paper about?
This paper introduces V-ReasonBench, a big, organized test (a “benchmark”) that checks how well AI video generators can “reason” about what they see and what they should create next. Instead of only judging whether a video looks pretty, V-ReasonBench measures whether the model can think through problems shown in pictures and produce the correct final result.
Why do we need a new test?
Modern video AIs can sometimes solve puzzles without being explicitly trained to do so. That’s exciting—but it’s hard to measure this kind of thinking in a clear, fair, and repeatable way. The authors created V-ReasonBench to be:
- unified (one place to test many kinds of visual reasoning),
- reproducible (others can repeat the test and get similar results),
- and focused on correct outcomes (not just nice-looking videos).
What questions did the researchers ask?
In simple terms, they asked:
- Can we design a reliable, fair way to measure reasoning in video generation models?
- What kinds of reasoning are these models good or bad at?
- Do video models reason better than image-only models, and when?
- Does making longer videos help reasoning, or not?
- Do automatic AI judges (VLMs) score videos correctly, and do those scores match human opinions?
How did they test the models?
Think of “reasoning in video” as step-by-step thinking with pictures. The paper uses an idea called “Chain-of-Frame” (CoF), similar to “Chain-of-Thought” in language. Here’s the core idea:
- The model is shown a starting image and an instruction (like a puzzle).
- It generates a short video where each frame is like a step in its thinking.
- The final frame is the model’s “answer.” The benchmark judges only this last frame to keep scoring simple and consistent.
To make this work well, the authors created tasks in four reasoning areas and used a mix of evaluation methods.
The four reasoning areas
To make their test well-rounded, the benchmark includes tasks across these dimensions:
- Structured problem-solving: math from pictures, following simple code, Sudoku, and finding the best move in Tic-Tac-Toe.
- Spatial cognition: fitting shapes, spotting symmetry, and connecting same-colored items with valid paths.
- Pattern-based inference: finishing sequences, solving analogies (“A is to B as C is to ?”), and following rules learned from examples.
- Physical dynamics: predicting slides on slopes, how water levels change in connected containers, and how temperature affects materials.
How they score the final frame
Because videos can be complex, they use three practical scoring methods—each explained with everyday analogies:
- Mask-based evaluation: Imagine putting a colored overlay on the important parts (like the playing area in Tic-Tac-Toe). The score focuses mostly on these areas, ignoring background changes that don’t matter.
- Grid-based evaluation: Think of the image as a chessboard. The test checks each square for the right piece, color, or shape, so tiny misplacements are caught.
- VLM-based evaluation: A lightweight AI “judge” reads or recognizes simple, clear outputs (like a number in a math problem or the result of a small code snippet). This is used only when it’s dependable.
They also use a simple metric called pass@5: each model gets up to five tries for each task; if any try is correct, it counts as a pass. This makes the test fair, because video generation can be a bit random.
The dataset setup
Most tasks use pairs of images: one “start” image and one “correct final” image. Models must generate a video that ends at the right final image. This design:
- keeps tasks clear and unambiguous,
- makes it easy to scale to many examples,
- and enables consistent scoring.
What did they find?
Here are the main results, explained simply:
- Different models have different strengths. For example, Sora-2 scored best overall in structured problem-solving, spatial understanding, and pattern-based reasoning. Hailuo-02 also performed strongly, especially in physical tasks. Vidu-Q2 did well in physical dynamics too.
- Physical reasoning is hard. Even good models that handle math or patterns can struggle with understanding forces, motion, and materials.
- Longer videos aren’t always better. Making the video longer (more “thinking frames”) didn’t consistently improve the final answer. Extra frames sometimes added distractions or even caused “hallucinations” (unrealistic or wrong steps).
- Video vs. image models: Video models are better at tasks that need simulating changes over time (like physics), because they can “think” frame-by-frame. Image-only models produce cleaner static answers and often do well on text-heavy or code-derived tasks, but they can miss the right physical outcome because there’s no motion to reason over.
- AI judges have limits. Vision-LLMs (VLMs) can misjudge complex, tiny, or grid-based visuals. That’s why V-ReasonBench uses multiple scoring strategies, not just one AI judge.
- Humans mostly agree with the benchmark. The automatic pass/fail decisions matched human judgments about 97% of the time, which is very high.
Why does this matter?
This work helps move AI video generation from “looks good” to “thinks well.” The benchmark:
- gives researchers a reliable way to measure reasoning in videos,
- shows where current models struggle (especially physical understanding and staying consistent across frames),
- encourages designs that combine clean static understanding with good temporal reasoning,
- and provides a clear target for building models that are more aligned with how humans reason and judge correctness.
In short, V-ReasonBench is a solid, unified test that can guide the next generation of video AIs toward being not just creative, but also correct and trustworthy.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a single, consolidated list of concrete gaps, limitations, and open questions that remain unresolved and could guide future research:
- Coverage and scale: The benchmark comprises 326 instances with 652 images; how does performance and reliability scale with substantially larger, more diverse task banks, including harder multi-step problems and richer distractor settings?
- Synthetic bias: Approximately 90% of tasks are procedurally generated in minimalist layouts; to what extent do findings generalize to natural, cluttered, camera-moved, or occluded real-world videos where perception noise and context complexity are high?
- Last-frame evaluation blind spots: End-state scoring cannot detect “right answer, wrong process” temporal inconsistencies; how can we evaluate causal coherence and physical law adherence across intermediate frames without prohibitive annotation?
- Process-sensitive task design: Can we construct tasks where only a correct causal trajectory produces the correct terminal state (e.g., path-dependent constraints, irreversible transformations) to reduce endpoint-only loopholes?
- VLM judge reliability: For tasks using VLM-based scoring (e.g., Sudoku, code execution, shape fitting), how can we quantify and reduce OCR errors, misreads of small cells, and layout misinterpretations, and benchmark evaluator variance across multiple VLMs?
- Threshold calibration: Task-specific pass/fail thresholds are not systematically validated; what procedures ensure calibrated, robust thresholds across tasks/models, and how sensitive are conclusions to threshold choices?
- Metric robustness: Mask- and grid-based metrics rely on pixel-level comparisons; how can metrics be made invariant to style changes and camera motion while remaining sensitive to structural correctness?
- Segmentation dependencies: Mask-based evaluation uses SAM-2 or templates; what is the impact of segmentation errors on scores, and can ground-truth regions be made robust to visual drift or occlusion?
- Grid granularity: How should grid cell size adapt to object scale and stroke thickness to avoid penalizing minor rendering or antialiasing artifacts?
- Pass@k sensitivity: The evaluation fixes k=5; how do rankings change with k, seed variability, temperature, sampling strategy, and decoding settings, and what is the sample-efficiency curve per model/task?
- Resolution and fps effects: Results are at 720p/768p and ~5s videos; how do resolution, aspect ratio, frame rate, and clip length affect reasoning accuracy and temporal coherence across tasks?
- Duration control for CoF: Longer durations do not consistently improve reasoning; what strategies (frame budgeting, stride, temporal attention, memory mechanisms, self-consistency across runs) effectively translate “more time” into better reasoning?
- Prompts and instruction robustness: How sensitive are outcomes to prompt phrasing, paraphrases, multi-lingual instructions, and noisy or contradictory directives, and can standardized prompt suites reduce bias?
- Physical dynamics breadth: Current physics tasks focus on sliding, communicating vessels, and temperature-induced changes; how do models fare on broader dynamics (collisions, elasticity, friction regimes, fluid turbulence, granular media, deformables) and 3D interactions?
- Causal law verification: Can we formalize automatic checks for conservation laws (momentum, energy), pressure equilibria, and kinematic constraints using physics simulators or symbolic validators aligned to generated trajectories?
- Sub-task granularity: Dimension-wise scores hide task-level failure modes; can we provide per-task breakdowns and error taxonomies (e.g., typical Sudoku mistakes, symmetry misclassification, pathfinding errors) to target model training?
- Human alignment depth: The study reports 97% agreement but does not detail inter-rater reliability (e.g., Cohen’s κ), disagreement sources, and cross-lab reproducibility; can we expand annotator pools and report reliability statistics per task?
- Construct validity: Do V-ReasonBench scores predict performance on downstream video reasoning applications (e.g., robotics planning, sports analytics)? Establishing predictive validity would strengthen claims of “reasoning” measurement.
- Model set and transparency: Evaluations target six commercial models with undisclosed training data; how do results change for open-source models, and can benchmark findings be normalized against known pretraining compositions to assess data contamination or overfitting on diagrammatic tasks?
- Image vs. video baselines: The comparison uses a single image model (NanoBanana); can we include stronger, diverse image reasoning baselines (e.g., OCR-specialized, code-readers, math-visual models) to better isolate temporal advantages?
- Hallucination mitigation: Observed temporal hallucinations are noted but not systematically addressed; which interventions (temporal-aware activations, causal regularizers, step-wise constraints, multi-run self-consistency voting) concretely reduce hallucinations in generative video reasoning?
- Minimalism-induced creativity bias: Models embellish sparse scenes, hurting structural accuracy; can training or decoding methods penalize unnecessary additions, and can “structure-preserving” priors be introduced to respect diagrammatic constraints?
- Task diversity within dimensions: Some dimensions (e.g., pattern-based inference) may underrepresent analogical and inductive reasoning in naturalistic settings; can we expand to cross-domain analogies, visual metasemantics, and rule induction from noisy examples?
- Evaluation reproducibility: API versions and default parameters may change; how can we version-control generation settings, random seeds, and evaluator prompts to ensure longitudinal comparability?
- Licensing and release details: The paper references a project page but does not specify data licensing, evaluator code availability, or reproducibility kits; clear release artifacts are needed for community adoption and extension.
- Adversarial and interactive reasoning: Tasks like Tic-Tac-Toe evaluate a single move rather than multi-turn adversarial planning; can we incorporate interactive environments where models must reason under opponent responses and partial information?
- Multimodal outputs: Some tasks could benefit from textual or symbolic outputs alongside final frames; how can the benchmark incorporate multimodal scoring (vision + text) to reduce reliance on pixel-matching and improve interpretability?
- Bias and fairness: Do models exhibit differential performance across color palettes, font styles, or cultural symbol sets in diagrams? Systematic fairness audits are missing.
- Generalization to long videos: The benchmark focuses on short clips; can we systematically evaluate long-horizon reasoning, temporal credit assignment, and memory fidelity over minutes-long sequences?
