Transform cameras, videos, and images with real-time fragment and compute shaders. Windows Beta 2 brings the ACMX interface, the established ACMX2 engine, and the new ACMXVK Vulkan engine together in one portable package.
Beta software: save your work and expect features to continue evolving.

How ACMX works
Media enters once. You choose how the GPU transforms it.
Start with a webcam, video file, or still image. The Qt interface manages the source, shader library, effect controls, playlists, audio and MIDI options, recording, and runtime log. Choose the renderer from the Backend menu.

Backend selection
Two paths through the same creative workspace
ACMX2 / OpenGL
The original, mature engine
ACMX2 runs through libmx2 and OpenGL. It carries forward the established GLSL workflow, shader packs, playlists, texture history, audio reaction, multipass effects, and recording.
Best for existing ACMX2 GLSL libraries.
Compiles source shaders through OpenGL at runtime.
Supports fragment and compute effects.
ACMXVK / Vulkan
The modern Vulkan pipeline
ACMXVK runs through MXVK. Its source libraries describe fragment and compute shaders in library.json; the interface builds them into SPIR-V and tracks build health.
Uses compiled SPIR-V shader passes.
Supports multipass chains, history textures, and custom uniforms.
Supports source editing, incremental builds, and live reload.
The interface is the bridge.
Switching backends changes the rendering engine and shader format, not the central process: select media, browse effects, control uniforms, react to sound or MIDI, preview the result, and record the finished video.
Typical workflow
From shader source to finished video
1
Choose ACMX2 or ACMXVK
Select the renderer from the Backend menu.
2
Open a shader library
Load an ACMX2 library or an ACMXVK library.json source manifest.
3
Build when needed
ACMXVK compiles changed .frag and .comp files into SPIR-V.
4
Select media and controls
Configure a camera, video, or image plus audio, MIDI, timing, and output.
5
Perform or process
Run one effect or a multipass chain, then record or save snapshots.
Creative tools
Built for live play and offline processing
Shader libraries
Browse large collections and monitor Vulkan build health.
Fragment + compute
Combine compatible shader types into multipass chains.
Audio reactive
Drive effects from microphone or source-video audio.
MIDI control
Map physical knobs and sliders to custom uniforms.
Recording
Encode processed video with quality and timing controls.
Snapshots
Save creative output in several supported image formats.

Running on Windows
Both backends, one interface
Windows Beta 2 can launch either rendering engine, manage large shader libraries, preview effects, and edit ACMXVK shader source without leaving the interface.
