Zaebects JPEG Glitch is a plugin for After Effects and Premiere Pro that uses the JPEG compression algorithm to create glitchy visual effects. By introducing controlled errors at various steps, or through manual value adjustments, it produces a glitch aesthetic exclusive to JPEG compression. A control panel lets you manipulate the amount and type of glitchiness.
The plugin processes each frame as a separate image, converts it to a JPEG, and returns it in the same picture format. All errors and glitches are added during the conversion stage, and any broken bytes are left there, so the output returns only healthy pictures. Rendered files remain functional yet look corrupted.
Parameters include a compression ratio that changes how much information an image contains, and a broken bytes control that sets how many bytes are altered. Quantization table settings let you adjust any of the 64 quantization table coefficient positions or replace a chosen number of values with random numbers within a specified range.
