Wonder Dynamics在AI增强视觉效果方面表现出色,其最新工具进一步自动化动画过程。该工具可将任意视频转化为完全可编辑的3D场景,包括角色等。它结合了演员替换功能和3D背景,虽非提供成品,但对动画前期制作很有用。创始人强调此工具可在客厅完成拍摄和编辑,且多摄像头拍摄的视频能转化为虚拟相机的同一场景。该工具输出为行业标准3D资产,可进行多种调整,目前处于测试阶段。

🎬Wonder Dynamics的最新工具能将几乎任何视频转化为完全可编辑的3D场景,包括角色等,实现了动画过程的进一步自动化。

🌟该工具将公司现有的演员替换功能与可自选的全比例3D背景相结合,可轻松将人替换为动画3D角色,并根据其动作进行调整。

💻此过程能提供快速的预可视化,生成的3D场景可在Blender、Maya或Unreal中编辑每个元素,对动画早期制作的多个阶段非常有帮助。

📹可以使用多个摄像头拍摄同一场景,视频到3D的流程会通过估算脚步移动等指标,将它们放置在虚拟相机的同一场景中,对早期的相机工作很有帮助。

🎁该工具的输出是行业标准的3D资产,拍摄后并非锁定,可对相机和角色动作进行拖拽调整,或完全重新组合和重新照亮场景。

Wonder Dynamics made a strong opening play in AI-enhanced visual effects, providing tools animators and filmmakers actually find useful — and earning the startup a prompt acquisition by Autodesk. Their latest tool further automates the animation process, letting you put in practically any video and get a fully editable 3D scene, characters and all.

The feature combines the company’s existing drop-in actor replacement, in which you could easily replace a person with an animated 3D character keyed to their movements, with a full scale 3D background of your choosing.

To be clear, as with all the company’s previous features, this is not intended to provide a finished product — just a base layer to build on. Animation is labor intensive, and location shooting is difficult and expensive — if you can film two friends walking down the hall and convert it to robots walking down a futuristic street, that’s super useful for previsualization, story flow, and other early stages of production.

“The idea is that you can shoot and edit your video in your living room, with desired performances, cut, and camera framings as you would want to see in your animation,” said Wonder Dynamics co-founder Nikola Todorovic. “This process would provide you with a quick previs and, most importantly, 3D scenes to edit each individual element in either Blender, Maya or Unreal.”

Impressively, you can use multiple cameras to shoot the same scene, as you might normally with human actors, and the video-to-3D flow will place them in the same scene as virtual cameras following the original motion by estimating foot travel and other metrics. Again, helpful for early in the process when camera work is being roughed out — not something you want to decide on shoot day!

You can see it in action here:

Unlike some generative and text to video (or video to video) type models, the output of the Wonder Animation tool is all industry-standard 3D assets. Once you shoot it, it’s not locked in — you can drag and drop the cameras and tweak the character’s movements, or totally recompose and relight the scene. Some of this was possible in the original Wonder Studio, but the focus here is on fully animated scenes rather than, say, replacing one actor with a CG character.

Anyone using Wonder Studio should be able to access the animation feature today, though it’s technically in beta and will probably see improvements as feedback is submitted.
