frame0002exr

frame0002exr is typically the name used for a single frame in a rendered sequence stored in the OpenEXR format. The exact filename is often frame0002.exr, with the number indicating the frame in the sequence. Some pipelines or file systems may present the name without the dot, resulting in frame0002exr, but it still denotes an OpenEXR image for that frame.

OpenEXR is a high-dynamic-range image format developed by Industrial Light & Magic. It supports multiple channels and preserves wide dynamic range and precision. EXR files can store color data, alpha, depth (Z), normals, motion vectors, and other data as either half-precision (16-bit) or full floating-point values. They can be organized as a single image or tiled for efficient access and processing, and they support a range of compression options to balance quality and file size.

In production pipelines, a frame file like frame0002.exr represents the rendered output for that frame. Depending on rendering settings, it may include multiple channels such as R, G, B, A, and additional channels like Z for depth, N for normals, and V for velocity. The choice of channels and compression is driven by downstream needs in compositing, color grading, or visual effects.

Naming conventions and directory structures are managed by render and comp pipelines to enable automated retrieval, sequencing, and playback. These files are typically processed by compositors, image editors, and render-management tools across animation, film, and game pipelines.

Common tooling for viewing or editing EXR files includes OpenEXR libraries and compatible software, as well as plugins and support in applications like Nuke, Blender, Houdini, Photoshop (via plugins), and ImageMagick.
