StochasticGrain vs Glitchforge

Unlike simple noise overlays, this app uses a physics-based approach where grain density responds to image brightness, just like analog film. Shadows show more grain, highlights stay cleaner. The result feels organic rather than digital. Built on academic research by Newson, Delon, and Galerne (2017) modeling stochastic film grain through Boolean models, with real-time optimizations informed by Zhang et al.'s 2023 SIGGRAPH work. These papers describe how actual silver halide crystals distribute in photographic emulsion. Exposure-dependent grain that responds to image luminance Real-time preview as you adjust Designed for film photography enthusiasts A passion project for anyone who appreciates the texture of analog photography.

Glitchforge is a video glitch studio that runs on your iPhone. Load a clip, stack effects, and watch your videos get messed up. Most glitch apps just paint effects on top of the picture. We edit the compressed video itself, in its own domain: the motion vectors, coefficients, and quantizers inside the H.264, MPEG-2, and MPEG-4 streams. Datamosh: motion comes unstuck from the picture, so one shot melts into the next and frames bleed together. Scrambled coefficients: blocks tear and smear. Warped blocks + posterization: the compression math is the effect. VHS + analog: tracking noise, color bleed, worn tape Pixel sort: pixels dragged into long streaks of color. Load a clip. Build a chain and reorder it if you need to. Tune each effect's settings and watch the picture change in unexpected ways. Scrub to any frame and save it, or export the whole clip. There is no account and no server. Your footage is processed on the phone and stays there. It works with no connection, anywhere you are ready to make art.
