About DeltaSketch
Real-time visual processing for artists, animators, and creators.
How Did We Get Here
Born from years of personal experimentation and iterative development, DeltaSketch has undergone several transformations—from early Java (Processing) tools to web and Python applications—before arriving at its current form as a native C++ desktop application.
What We Build
DeltaSketch is a Windows application that processes visual media in real-time. It captures frames from cameras, webcams, and video files, applies configurable effect pipelines on your GPU, and exports the results as image sequences or video files. It is designed for artists, animators, and creators who want to experiment with visual effects, create stop-motion animations, time-lapse videos, and GIFs without the overhead of complex software suites. The application is meant to be modular and extensible, allowing users to create custom effects and processing chains through a built-in GLSL compute shader system. There is already much in the works for future releases, and the software will keep evolving and probably change in ways that are not yet anticipated. We welcome feedback and suggestions from our users to help shape the future of DeltaSketch.
Technology
DeltaSketch is built with modern C++ and OpenGL. The effects engine runs entirely on your graphics card, ensuring smooth real-time preview even with complex processing chains. The application supports OpenGL 3.3 as a minimum, with OpenGL 4.3 required for advanced compute shader features.
Video export is powered by FFmpeg, providing broad codec support for AVI, WEBM, and other formats. The custom shader system allows advanced users to write GLSL compute shaders with live reload, enabling unlimited creative possibilities beyond the built-in effect library.
Privacy & Data
DeltaSketch is designed with privacy in mind:
- No usage telemetry — we do not collect data about how you use the software
- No content transmission — your captured images, projects, and creative work never leave your machine
- Minimal license data — activation transmits only a hashed hardware identifier and license key; no personal information is collected
- No account required — you can use the trial without creating an account
Pricing
DeltaSketch is available as a one-time purchase with no recurring subscriptions. The license covers up to 2 devices and includes all updates for the current major version. A 14-day free trial is available with all features unlocked.
