Convert AVI to FBX

Understanding AVI and FBX file formats

AVI (Audio Video Interleave) is a multimedia container format developed by Microsoft, primarily used for storing video and audio data. It is widely supported and commonly used for video playback and editing.

FBX (Filmbox) is a proprietary file format (.fbx) developed by Autodesk for 3D models, animations, and scenes. It is extensively used in 3D modeling, animation, and game development workflows.

Can you convert AVI to FBX?

Direct conversion from AVI (a video format) to FBX (a 3D model/animation format) is not straightforward, as they serve fundamentally different purposes. However, if your goal is to extract motion or animation data from an AVI video and use it in a 3D environment, you can use motion capture (mocap) software to analyze the video and generate FBX animation data.

How to convert AVI to FBX

1. Extract motion data from AVI: Use motion capture software such as Adobe After Effects (with plugins like Adobe Character Animator or DeepMotion), or open-source tools like OpenPose to analyze the video and extract motion data.
2. Export animation as FBX: Once the motion data is captured, import it into a 3D software like Autodesk Maya or Blender. Then, use File → Export → FBX to save the animation or 3D scene as an FBX file.

Recommended software for AVI to FBX conversion

• DeepMotion Animate 3D: Upload your AVI video, and the service generates an FBX animation file from the detected motion.
• Adobe After Effects (with plugins): Track motion in AVI and export to 3D software for FBX export.
• Blender: Import motion data and export as FBX using File → Export → FBX.

Summary

While you cannot directly convert an AVI video to an FBX file, you can use motion capture tools to extract animation data from the video and export it as an FBX file using 3D software. DeepMotion Animate 3D is one of the most user-friendly solutions for this workflow.
