「BUFFER OVERFLOW」は FontVibe AI で作成したグリッチの文字エフェクトです。赤とシアンのチャンネルずれで裂けた白いサンセリフ大文字。水平の変位スライスと走査線が走り、夜の濡れたネオン街に映ります。

A 16:9 YouTube thumbnail with the title "BUFFER OVERFLOW" stacked on two lines, "BUFFER" above and "OVERFLOW" below, in massive heavy condensed sans-serif capitals that fill about 80% of the frame width. The lettering is torn digital static: about 35% of each stroke is eaten by dense white, grey and black noise-pixel scatter, and the letter skeleton stays readable through it. Irregular horizontal bands of pure TV static slice across the letters. Every letter edge carries a red ghost copy shifted about 7px left and a cyan ghost copy shifted about 7px right. Dense semi-transparent CRT scan lines, spaced 3-4px apart, run across the whole lettering. Four sharp rectangular chunks of letter pixels are displaced sideways by 10-25px at different heights. The right end of "OVERFLOW" bursts into a spill of loose square pixel fragments and tiny static blocks that scatter off the edge of the letters and overflow past the right side of the frame, as if the word has exceeded its buffer. A subtle cyan-white phosphor bloom glows from the letter boundaries. The base letter colour is off-white, with red and cyan fringes. The background is a near-black blue-black digital void with faint scan lines and a few dim, sparse data-pixel specks. Nothing else is in the frame. Layout: the two-line title is centred and dominant, with generous dark margin above and below. High contrast, instantly readable at small thumbnail size, with a professional digital corruption look.
