Opus 5.5 用 Python+ffmpeg 逐帧做暗黑霓虹故障风视频
给 Claude Opus 5.5 一段提示词，用 rembg 抠像、5 级色调分离、datamosh 拖影和垂直滴落效果逐帧处理视频，并生成蒸汽波故障音轨。
Claude Opus 5.5 Prompt: Apply a dark neon glitch-art effect to the attached video (Python + ffmpeg, frame by frame): 1. Cut out the subject with rembg (isnet-anime for anime/illustration, isnet-general-use for real footage). Make the background pure black. 2. Posterize the subject to 5 brightness levels and recolor it with a 3-color palette on black: main color for cool/neutral areas (cyan #14b8f0), mid color (violet #6438c4), accent for warm/red areas (magenta #ff2ad4). Keep it dark: most of the image black or navy, only the highlights glow. Let the color-patch edges crawl slightly with noise. 3. Add a magenta rim light on the subject's left edge. 4. Datamosh: wherever the current frame is empty, keep the previous frame shifted a few px down and faded (melting ghost trails). Also copy ~3% of 24px blocks from the previous frame with a small random offset. 5. Vertical drips: in ~30% of the columns, smear bright pixels upward (up to ~300px) and downward (~150px). Mix 2–8px wide drips with thin vertical scratch lines in the palette colors, denser near the subject. 6. Light grain + vignette. Keep the original resolution and fps, export as H.264 MP4. Generate an original vaporwave-glitch soundtrack (~-12 LUFS) / make it a seamless loop where the last 1s drips into the first 1s column by column.
