.85 — Autodesk Animator RLE
Autodesk · 1989
A proprietary animation frame format used by the legacy Autodesk Animator software.
Key Features
- Stores animation frames for Autodesk Animator.
- Utilizes Run-Length Encoding (RLE) for compression.
- Lossless compression preserves image data accurately.
- Proprietary format, limited compatibility with modern software.
Best For
- Storing animation sequences specifically for Autodesk Animator.
- Situations requiring exact, lossless frame data.
- Archiving historical animation assets.
Less Ideal For
- Web animation due to poor compatibility and large file sizes.
- Modern video editing workflows.
- Sharing animations across different software platforms.
- High-quality, complex animation rendering.
Common Use Cases
- Archiving animation projects created in Autodesk Animator.
- Restoring or preserving early computer animations.
- Retro game development or modding.
- Historical computer graphics research.
How to Open It
- Attempt to open with legacy versions of Autodesk Animator or compatible emulators.
- Use specialized retro animation or graphics conversion tools that might support the format.
- If within a game or application, the .85 file is likely loaded directly by the software.
What is a .85 file?
The .85 file extension is associated with Autodesk Animator, an early animation software popular in the late 1980s and early 1990s. These files typically store animation frames in a Run-Length Encoded (RLE) format, which is efficient for simple, lossless compression. While it was revolutionary for its time, enabling the creation of animated sequences for computer graphics and games, its proprietary nature and the evolution of animation software have made it largely obsolete. Modern users are unlikely to encounter .85 files unless they are working with historical animation data or retro gaming preservation efforts.

Frequently Asked Questions
Autodesk Animator was a 2D animation software popular in the late 1980s and early 1990s, known for its intuitive interface and tools for creating animated sequences.
Editing .85 files directly is difficult due to proprietary software requirements. Conversion to a more editable format is recommended.
The software is outdated, and modern animation and video formats offer greater compatibility, features, and efficiency.
Technical Details
Autodesk Animator RLE (.85) files store animation sequences as a series of frames. The RLE compression within this format is lossless, meaning no image data is lost during compression. This makes it suitable for preserving the exact pixel data of each frame, though it can result in larger file sizes compared to modern lossy compression techniques. The specific structure is tied to the internal workings of Autodesk Animator.
