Understanding Real Analog Video Signals vs Digital Glitch
Digital glitches rely on pixel sorting and square block compression artifacts. Analog television and video tape (NTSC/PAL), however, encode color information as continuous radio wave signals (Luminance Y, In-phase I, Quadrature Q).
Signal by aescripts procedurally emulates this analog signal flow inside After Effects, allowing you to manipulate horizontal sync timing, chroma phase delay, and signal noise mathematically.
Mastering YIQ Color Bleeding & Scanline Noise
- Chroma Delay: Offsets the color signal relative to luminance, creating authentic horizontal color bleeding seen on vintage CRT monitors.
- Sync Drift & Skew: Simulates a slipping VCR tape head by skewing horizontal scanlines diagonally.
- Noise Modulation: Injects high-frequency analog static into the signal without producing digital grain.
Creative Workflows: Music Video Title Reveals
Animate Signal’s Signal Loss parameter from 100% to 0% over 15 frames to make text snap cleanly out of broadcast static into crisp focus. Pair this with punchy sound design from our Cinematic SFX Packs for maximum impact.
Pairing with Real CRT Overlays
For ultimate realism, combine Signal with 4K CRT monitor curvature mattes and scanline overlays available in our editing asset packs.
