EgoEdit: Dataset, Real-Time Streaming Model, and Benchmark for Egocentric Video Editing (2512.06065v1)
Abstract: We study instruction-guided editing of egocentric videos for interactive AR applications. While recent AI video editors perform well on third-person footage, egocentric views present unique challenges - including rapid egomotion and frequent hand-object interactions - that create a significant domain gap. Moreover, existing offline editing pipelines suffer from high latency, limiting real-time interaction. To address these issues, we present a complete ecosystem for egocentric video editing. First, we construct EgoEditData, a carefully designed and manually curated dataset specifically designed for egocentric editing scenarios, featuring rich hand-object interactions, while explicitly preserving hands. Second, we develop EgoEdit, an instruction-following egocentric video editor that supports real-time streaming inference on a single GPU. Finally, we introduce EgoEditBench, an evaluation suite targeting instruction faithfulness, hand and interaction preservation, and temporal stability under egomotion. Across both egocentric and general editing tasks, EgoEdit produces temporally stable, instruction-faithful results with interactive latency. It achieves clear gains on egocentric editing benchmarks-where existing methods struggle-while maintaining performance comparable to the strongest baselines on general editing tasks. EgoEditData and EgoEditBench will be made public for the research community. See our website at https://snap-research.github.io/EgoEdit

EgoEdit: A Dataset, Real-Time Model, and Benchmark for Egocentric Video Editing
Introduction
The instruction-driven editing of egocentric videos introduces technical requirements beyond those addressed by conventional video editing systems, particularly for immersive AR applications. First-person perspectives present unique domain shifts such as rapid egomotion, complex hand-object interactions, and frequent occlusions, constituting an underexplored frontier for generative video editing and AR. Most existing AI video editors are optimized for exocentric (“third-person”) content and are encumbered by high-latency, batch-oriented pipelines, impeding real-time, user-in-the-loop usage.
To address these domain and latency gaps, "EgoEdit: Dataset, Real-Time Streaming Model, and Benchmark for Egocentric Video Editing" (2512.06065) provides a complete ecosystem: (1) EgoEditData— a manually curated dataset focusing on egocentric interactions; (2) EgoEdit— an instruction-guided editor featuring a streaming, real-time, single-GPU implementation; and (3) EgoEditBench— a benchmark evaluating faithfulness, hand preservation, and temporal stability under egomotion. This infrastructure establishes a reproducible and extensible foundation for research at the intersection of video generative models, AR, and human-focused video understanding.
EgoEditData: Curated Egocentric Video Edit Dataset
EgoEditData is specifically constructed to address egocentric video’s data scarcity and domain-specific complexity, thereby enabling robust model training and evaluation. The dataset’s curation pipeline proceeds as follows:
- High-fidelity hand-object interaction focus: Videos from Ego4D and EgoExo4D datasets are filtered for active hand-object manipulation using state-of-the-art hand/object segmentation (SAM 2, Grounded SAM) and VL models (Qwen2.5-VL-32B).
- Multi-stage manual filtering: Human annotators systematically review hand and object masks and synthesized edits to enforce mask and edit quality.
- Instructional alignment: Edit pairs are coupled with accurate, descriptive instructions generated with LLMs (e.g., GPT-5 Mini).
- Edit diversity: Object substitution (including both ordinary and imaginary objects) and object removal iterations are constructed for each segment, with synthetic edited references generated via Qwen-Image and Wan 2.1 VACE 14B.
Following aggressive filtering (retaining only 0.4% of candidate videos), EgoEditData contains 10.9k original and 38.8k synthetic egocentric videos (∼70 hours), resulting in 99.7k edit pairs with dense, domain-specific instruction coverage. This scale and attention to domain-specific quality permit models to learn to manipulate objects and hands in challenging first-person scenes, which are poorly represented or absent in other public datasets.

EgoEdit: Real-Time Egocentric Video Editing Model
EgoEdit extends a pretrained video generator (based on latent Wan 2.1 autoencoder with a transformer backbone) for low-latency, instruction-following video editing in the egocentric regime. Key technical innovations include:
- Architecture for low-latency conditioning: Rather than standard sequencewise patch concatenation (which quadratically increases computation in transformers), EgoEdit employs channel-wise concatenation for source and noisy target video streams, dramatically reducing inference overhead and thus supporting real-time rates.
- Rectified Flow Matching: Training uses deterministic flow matching, learning a continuous path between noisy and clean data. This formulation supports efficient ODE-based inference compared to standard diffusion models.
- Autoregressive distillation for streaming: The accurate but slow 80-NFE base model is distilled into a 4-NFE, real-time, autoregressive generator using bidirectional DMD distillation followed by Self Forcing. The latter exposes the model to its own rollout during distillation, mitigating exposure bias and enabling chunk-wise, streaming inference suitable for in-the-loop usage.

EgoEdit-RT (the real-time streaming model) achieves 38.1 fps with 855ms first-frame latency on a single H100 GPU at 512×384px, supporting user-facing AR applications previously inaccessible to batch-oriented offline video editors.

EgoEditBench: Benchmark for Egocentric Video Editing
EgoEditBench is designed to evaluate the unique challenges posed by egocentric content—namely instruction faithfulness, rigorous hand and object preservation, and temporal stability under dynamic camera motion. It comprises 1700 source videos, each annotated for 15 distinct egocentric editing tasks (Add/Remove/Change Object, Stylization, Camera Pose, Reasoning, etc.), and leverages diverse synthetic conditioning signals (canny edges, pose, depth). The benchmark protocol ensures maximal diversity and disjointness from training data.
Comparison to prior evaluations on general video editing (e.g., EditVerseBench) highlights the relative decline in baseline editor performance (e.g., Lucy Edit, InsV2V) when facing egocentric input, while EgoEdit and EgoEdit-RT demonstrate minimal VLM score drop between general and egocentric tasks. This underscores the importance of domain-aligned data and architectures for first-person video editing.

Experimental Results and Ablations
Qualitative and quantitative evaluations reveal that EgoEdit(‑RT) achieves state-of-the-art results on EgoEditBench, with only a 0.24 VLM point gap between general and egocentric tasks (versus 0.83/0.47 drop for Lucy Edit/InsV2V). Competing real-time streaming models exhibit a pronounced quality gap relative to EgoEdit-RT, and frame-propagation approaches retain performance only when provided with an EgoEdit-generated starting frame.
Figure 5: Qualitative comparison on EgoEditBench, illustrating EgoEdit and EgoEdit-RT’s superior preservation of hand-object integrity and temporal coherence relative to baselines.
Ablations show monotonic improvements in egocentric editing performance as more EgoEditData edits are included during training, confirming the dataset’s critical role. Streaming model ablations further show that Self Forcing yields an optimal balance of latency and faithfulness, although slight qualitative degradation is observed in out-of-distribution, heavily occluded, or complex temporal edits.

In-the-Wild and Exocentric Evaluation
EgoEdit-RT maintains egocentric edit quality when applied to exocentric scenes as well, consistent with strong domain generalization. In-the-wild tests demonstrate emergent behaviors such as hand and object structure preservation, realistic object-environment interactions, and context-sensitive AR-style visual effects. Some limitations remain in inducing structural scene changes or handling persistent occlusions.

Discussion and Future Implications
EgoEdit’s architectural, data, and evaluation contributions provide a comprehensive solution for AR-centric video editing. The release of EgoEditData and EgoEditBench is likely to accelerate progress in robust generative models for first-person, interactive video tasks, a precondition for next-generation AR experiences. Model design principles (e.g., channelwise source concatenation, autoregressive distillation) are directly applicable to related domains (robotics, wearable computing, lifelogging) requiring real-time perception and generation.
While the current real-time pipeline achieves <1s total latency and strong in-distribution robustness, future work may target further latency reduction, upscaled resolution/frame rate, and even stronger temporal consistency under long-horizon and occluded interactions. Additionally, self-improving architectures that jointly adapt instruction grounding and object-hand segmentation under open-world settings may further strengthen performance as AR video applications evolve.
Conclusion
EgoEdit represents a significant advancement in the instruction-guided editing of egocentric video, unifying domain-aligned data curation, latency-optimized autoregressive modeling, and task-aligned benchmarking. Through EgoEditData, EgoEdit, and EgoEditBench, the system demonstrates state-of-the-art performance for real-time AR-centric video editing, enabling robust, user-in-the-loop generative applications and laying the groundwork for future research at the intersection of vision, language, and real-time interactive AR (2512.06065).

Overview
This paper is about making it easy to edit first-person videos in real time using plain language instructions. Think of wearing a camera (like a GoPro) and saying, “Replace the apple I’m holding with a glowing crystal,” and the video changes while you move, without messing up your hands or the scene around you. The authors build three things to make this happen:
- a high-quality dataset of first-person (egocentric) video edits,
- a fast, real-time editing model,
- and a fair benchmark to measure how well different methods work.
Key Questions
The paper tries to answer simple, practical questions:
- Can we edit first-person videos live, using text instructions, while the camera moves a lot?
- Can we keep hands and objects looking correct during edits, even when they touch, overlap, or move quickly?
- Can we do all this with low latency (very short delay), so it feels interactive for augmented reality (AR)?
How They Did It
To tackle the problem, the authors created an end-to-end setup focused on three parts.
1) EgoEditData (the dataset)
They built a carefully curated dataset of “before and after” video pairs and clear edit instructions, all from a first-person view. It focuses on realistic hand–object interactions, like:
- removing an object someone’s holding,
- replacing it with another object (ordinary or imaginary),
- and making sure the hands look natural and are preserved in the final edit.
How they made it:
- They started with real first-person videos.
- They used AI tools to detect hands and find the exact object being manipulated.
- They generated edited versions where the object is changed or removed.
- They had humans review the results and keep only the high-quality edits.
- They wrote precise, descriptive instructions for each pair.
Result: 49.7k videos and 99.7k instruction–edit pairs, all focused on egocentric scenarios.
2) EgoEdit (the real-time model)
They trained a video editor that follows text instructions and can run fast enough to be used live.
Key ideas explained in everyday terms:
- Start with a strong video generator (a model that can make videos from text).
- Teach it to edit instead of creating from scratch by feeding it:
- the original video,
- the desired instruction,
- and training it on lots of “before/after” examples so it learns how to change only what’s needed.
- Make it fast through “distillation,” which is like compressing a slow but smart model into a quicker version. They use two steps:
- DMD: reduces the number of generation steps so it runs faster.
- Self-Forcing: the model practices on its own outputs and learns to correct its mistakes over time, which helps it keep videos consistent as they stream.
Streaming means the model edits chunk by chunk while the video is recorded, so you see the first edited frame quickly. Their fast version, called EgoEdit-RT, reaches about 38.1 frames per second, with the first edited frame showing in roughly 0.855 seconds on a single GPU.
3) EgoEditBench (the benchmark)
They built a fair test suite for first-person video editing that checks:
- instruction faithfulness (does the edit match what you asked?),
- hand and interaction preservation (are hands and touched objects kept intact?),
- temporal stability (does the edit stay consistent across frames while the camera and hands move?).
It covers 15 typical AR-style tasks, like adding/removing objects, changing styles or backgrounds, and using guides like sketches, poses, or depth maps. It uses automated scoring to compare different methods in a consistent way.
Main Findings
Here are the key results that the authors highlight:
- EgoEdit (the base model) and EgoEdit-RT (the fast streaming version) produce edits that follow instructions well, stay stable over time, and keep hands and interacting objects looking correct.
- On egocentric tasks (first-person videos), EgoEdit beats other methods that struggle with rapid camera motion and hand–object overlaps.
- On general editing tasks (third-person videos), EgoEdit stays competitive with top methods.
- EgoEdit-RT, the real-time version, is almost as good as the full model but runs fast enough for interactive use.
- The curated dataset, EgoEditData, significantly boosts performance: more egocentric examples lead to better editing in first-person scenarios.
Why This Matters
This work moves us closer to live, language-driven AR experiences. Imagine apps where you can:
- restyle your surroundings on the fly,
- swap out objects you’re holding with fun or useful items,
- add effects or characters that react to your movements,
- all while keeping your hands and the scene realistic.
Beyond cool demos, the dataset and benchmark give researchers a common foundation to build and compare new methods. The model’s real-time speed means it can be used in interactive settings, like AR glasses or mobile devices in the future.
A simple note on limitations
While strong, the model isn’t perfect:
- Very tricky or unusual edits can still fail.
- If an object disappears behind something and reappears, consistency can drop.
- It runs at a modest resolution and frame rate, and the first-frame delay, while under a second, could be even lower.
Even with these limits, the paper offers a complete ecosystem—data, model, and benchmark—that makes real-time, instruction-guided editing of first-person videos practical and measurable.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a focused list of what remains missing, uncertain, or unexplored, written to be directly actionable for future research.
- Real-world human evaluation for AR: No user studies quantify perceived edit fidelity, comfort, latency tolerance, or interaction quality in head-mounted AR settings; design controlled studies comparing EgoEdit/EgoEdit-RT vs baselines on task success and UX.
- Metric validity in egocentric settings: Heavy reliance on VLM-based scoring, Pick Score, and automated Text Alignment may not capture hand geometry preservation, occlusion handling, or interaction plausibility; develop human-validated and task-specific metrics (e.g., hand mesh consistency, contact plausibility, edit locality).
- Long-horizon stability and drift: Streaming generation is evaluated on short clips and small chunks (first chunk 9 RGB frames, next chunks 12 frames); measure identity drift, hand-object alignment, and exposure bias over multi-minute egocentric streams and propose training/metrics to address it.
- Occlusion robustness: Authors note weaker performance when edited objects are temporarily occluded; create benchmarks and training augmentations for extreme occlusions and reappearance, and measure frame-reacquisition stability.
- Physics and causal interaction limits: Inserted objects do not induce consequential environmental changes (e.g., swords do not cut, objects do not move real items); investigate lightweight physics priors, contact-aware generative constraints, or hybrid perception–simulation to improve causal realism.
- Latency optimization trade-offs: First-frame latency (855 ms) is dominated by chunk recording (3 latent ≈ 9 RGB frames); paper effects of smaller chunk sizes on temporal consistency, guidance, and exposure bias, and explore predictive pre-roll or partial-frame streaming.
- Resolution and frame rate constraints: Model runs at 512×384px and 16 fps, below typical AR (≥720p, ≥30–60 fps); identify bottlenecks (autoencoder, transformer, KV cache) and develop scalable architectures, distillation, or quantization to achieve 720p/1080p at interactive frame rates.
- Mobile and edge deployment: Results are reported on a single H100 GPU; quantify performance, power, and thermal behavior on mobile SoCs/AR headsets, explore on-device acceleration, 8-bit/4-bit quantization, and memory–latency trade-offs.
- Benchmark completeness and reproducibility: EgoEditBench uses GPT-generated instructions and automated signals; provide fixed seeds, human-curated prompts, and ground-truth targets to reduce LLM-induced variability and allow rigorous, reproducible comparisons.
- Coverage of reference/mask-based interactive editing: The model does not support reference image conditioning or edit-with-mask tasks (excluded from EditVerseBench evaluation); extend conditioning modalities (masks, sketches, reference frames) and test interactive local edits guided by gestures/voice.
- Dataset domain bias: EgoEditData derives from Ego4D/EgoExo4D and filters out jitter/blur; measure generalization to low-light, motion-blur, extreme egomotion, outdoor/industrial scenes, varied FOVs (e.g., fisheye), and consumer AR devices.
- Mask quality and ground truth: Hand/object masks rely on SAM 2 prompted by detectors; quantify failure rates, provide human-annotated masks for a subset, and paper how mask errors propagate to editing quality.
- Instruction generation and bias: Edit instructions are LLM-generated (GPT-5 Mini) and may encode style/bias; audit instruction diversity, ambiguity, and cultural bias, and release a human-curated subset to disentangle instruction quality from model performance.
- Reliance on closed or proprietary components: Data synthesis (Wan 2.1 VACE 14B), LLMs (GPT-5 Mini), and teacher models may be unavailable to many labs; evaluate alternative open-source pipelines, report sensitivity to different teachers/autoencoders, and document compute requirements for reproducibility.
- Ablation scope and scaling laws: Distillation ablations focus on DMD + Self-Forcing; systematically compare APT2 (1-NFE), different chunk sizes, guidance schedules, KV caching strategies, and sequence lengths to establish scaling laws for egocentric streaming editing.
- Multi-object and compositional edits: Dataset emphasizes single manipulated object edits; benchmark and train for multi-object, multi-step, and compositional edits (e.g., “replace mug, restyle table, add lighting” in one pass), with measures of instruction coverage and interference.
- Robust instruction following under OOD language: Authors note weaker proficiency on out-of-distribution instructions; build robustness via paraphrase augmentation, multilingual prompts, disfluencies, multi-turn refinement, and explicit error detection/recovery in streaming loops.
- Hand preservation fairness: Hands are central but fairness across skin tones, accessories (rings, watches), gloves, and prosthetics is unreported; audit and mitigate demographic/appearance biases in hand preservation and interaction fidelity.
- Safety, privacy, and ethical considerations: Egocentric streams may include bystanders and sensitive environments; paper on-device processing, privacy-preserving training, red-teaming for harmful edits, and AR-specific safety guidelines (e.g., not inserting objects that occlude hazards).
- Ground-truth alignment of synthetic targets: Edited “after” videos are generated by another model and filtered; quantify mismatch between intended instructions and synthetic outcomes, and establish human-verified targets to calibrate instruction faithfulness.
- Generalization to varied hardware and camera pipelines: Performance across different sensors, rolling-shutter artifacts, stabilization methods, and compression settings is unexplored; build cross-device benchmarks and characterize robustness.
- Error accumulation and recovery in streaming: Develop mechanisms to detect accumulated artifacts (e.g., jitter, texture drift) and recover gracefully mid-stream (re-anchoring to the source), with measurable recovery metrics and user-controllable resets.
- Integration with AR interaction primitives: Explore real-time edit control via gaze, hand gestures, spatial anchors, and scene graphs; measure responsiveness, accuracy, and conflicts between edits and tracked anchors in interactive AR applications.

- Tools/workflows: Inline watermark insertion; verifiable manifests that track instructions and timestamps.
- Dependencies/assumptions: Ecosystem adoption; robust watermarking against compression/resizing; user-facing disclosure norms.
- Agentic, context-aware AR editors (Software, Consumer AI)
- What: Personal AR assistants that learn user preferences and proactively apply/recommend egocentric edits during tasks.
- Tools/workflows: Integration with MLLMs, calendar/task context; safety layers for instruction gating.
- Dependencies/assumptions: Privacy preservation; robust instruction grounding; drift and hallucination control.
- High-resolution, physics-aware world editing (3D Vision, Simulation)
- What: Edits that cause physically plausible changes (e.g., cut objects, deform materials), with consistent lighting and contact effects.
- Tools/workflows: 3D scene reconstruction; differentiable physics and material models; joint video-3D consistency training.
- Dependencies/assumptions: Significant research in 3D-aware video models; compute and latency costs; safety implications.
- MEC/edge deployments for ultra-low latency (Telecom, Cloud)
- What: 5G multi-access edge computing to deliver <300 ms end-to-end editing for mobile AR.
- Tools/workflows: Telco-integrated GPU edge nodes; adaptive bitrate and chunk size control; SLA monitoring with EgoEditBench KPIs.
- Dependencies/assumptions: Telco partnerships; capex/opex for GPUs; robust failover.
- Domain-adapted training suites for egocentric understanding (Academia, Foundation Models)
- What: Use EgoEditData and EgoEditBench to pretrain and evaluate egocentric perception models (hand-object segmentation, tracking, language-grounded understanding).
- Tools/workflows: Benchmark-leveraged CI for research; public leaderboards; task-specific fine-tuning kits.
- Dependencies/assumptions: Continuous updates to counter dataset bias; consent and anonymization standards.
Notes on Feasibility and Cross-Cutting Dependencies
- Hardware/latency: EgoEdit-RT achieves ~855 ms first-frame latency and ~38 fps at 512×384 on a single H100 via cloud; on-device deployment requires further compression and hardware acceleration.
- Quality limits: Model may underperform on heavy occlusions, rare instructions, and strong structural scene edits; current FPS and resolution may be insufficient for some professional uses.
- Data/governance: Use of egocentric content raises privacy concerns; any deployment should include disclosures, consent flows, and provenance/watermarking.
- Integration stack: Successful products will pair EgoEdit(-RT) with camera calibration, SLAM (for anchoring), bandwidth adaptation, and safety layers (content moderation, instruction filtering).
- Licensing: Third-party components (Wan autoencoder, Qwen, SAM 2, dataset derivatives) and newly released assets must be used within their licenses and terms.
