3DV-TON — Textured 3D-Guided Consistent Video Try-on via Diffusion Models

TL;DR 3DV-TON replaces per-frame warping with textured, animatable 3D human guidance and a diffusion UNet initialised from Stable Diffusion 1.5 + AnimateDiff. It cuts VFID on ViViD to 10.97 (from 17.29 for CatV2TON), introduces the 130-video HR-VVT benchmark at 720p, and ships code plus weights so teams can stand up consistent try-on pilots.

What is 3DV-TON?

3DV-TON is a video try-on framework from Alibaba DAMO Lab that keeps garment identity and motion consistent across frames. Instead of trusting pure 2D warping, it reconstructs a single textured 3D mesh from a keyframe, animates it with video-driven SMPL sequences, and feeds that textured guidance to a diffusion UNet. The paper debuts at ACM MM 2025 and arrives with a project page, inference code, model weights, and a new evaluation set.

Why it matters for video commerce teams

• Drives conversion by preserving logos, textures, and fabric flow when shoppers see garments on moving bodies.
• Tackles the usual "good stills, jittery footage" failure mode with explicit motion references rather than heavier temporal smoothing.
• Adds HR-VVT (130 videos at 1280×720) so you can evaluate beyond the low-res, single-view ViViD standard.
• Ships open weights and a reproducible preprocessing stack (masking, SMPL fitting, 3D reconstruction), making it viable for in-house experimentation.

Inside the pipeline

1. Adaptive keyframe selection chooses the cleanest video frame and runs a 2D image try-on (CatVTON or similar) to produce an initial garment-wearing person.
2. Animatable textured 3D mesh: ECON-style reconstruction with SMPL-X refinement (10 iterations) creates a clothed human mesh. The team freezes pose parameters and only optimises shape, translation, and camera scale so reconstruction completes in ~30s.
3. Video-driven animation: SMPL sequences from GVHMR/Video-based HPS rig the mesh so textures follow body motion without stretching.
4. Rectangular masking expands the edit region, preventing original garment leakage before the diffusion pass.
