Signal is an After Effects plugin from Zaebects that produces an authentic emulation of analog glitches for old-school TV vibes. It recreates old videotape aesthetics through real analog signal emulation, and now works in Premiere Pro as well.
The plugin offers many parameters and many ways to degrade any part of the signal. It includes several types of noise and authentic TV bend distortion for shaping the analog glitch effect.
Signal reaches version 1.2.3, last updated June 11, 2022. Earlier updates added Premiere Pro support in version 1.1.0 and Apple silicon compatibility in version 1.2.1, and version 1.2.2 fixed an issue with old macOS. Compatibility spans After Effects and Premiere Pro from CC 2017 through 2026, covering a long run of releases. Signal is listed as free here.
