Convert BVH to ANIM

Understanding the BVH and ANIM file formats

BVH (Biovision Hierarchy) is a widely used file format for storing motion capture data. It contains both the skeleton hierarchy and the motion data, making it popular in animation, game development, and 3D character rigging.

ANIM is a file format commonly used in Autodesk Maya and other 3D animation software to store animation data. ANIM files typically contain keyframe information for objects, bones, or characters, and are used to transfer animation between scenes or rigs.

Why convert BVH to ANIM?

Converting BVH to ANIM allows you to use motion capture data from BVH files directly in Maya or compatible 3D animation tools. This is essential for animators who want to leverage existing motion data in their Maya projects.

How to convert BVH to ANIM

There is no direct one-click converter for BVH to ANIM, but the process can be accomplished using Autodesk Maya with the following steps:

1. Open Maya and create or import a skeleton compatible with your BVH file.
2. Import the BVH file using the File → Import menu. You may need to enable the BVH import plugin (Windows → Settings/Preferences → Plug-in Manager).
3. Once the BVH motion is applied to your skeleton, select the animated objects or joints.
4. Export the animation as an ANIM file using File → Export Selection and choose ANIM as the file type.

Alternatively, you can use third-party tools or scripts, such as MotionBuilder or Open3D Motion Converter, to assist with the conversion process, but Maya remains the most reliable method.

Recommended software for BVH to ANIM conversion

• Autodesk Maya – Industry-standard for animation and supports both BVH import and ANIM export.
• Autodesk MotionBuilder – Advanced motion editing and retargeting, can help prepare BVH data for Maya.
• Open3D Motion Converter – A free tool for converting and retargeting motion capture data, though ANIM export may require Maya.

Tips for successful conversion

• Ensure your skeleton in Maya matches the hierarchy of the BVH file for accurate retargeting.
• Check for any scaling or orientation issues after import and before exporting to ANIM.
• Use Maya's HumanIK system for easier retargeting and animation transfer.
