Windows 文件路径要求

强制要求：在 Windows 上始终使用反斜杠表示文件路径

在 Windows 上使用 Edit 或 Write 工具时，必须在文件路径中使用反斜杠（\），而非正斜杠（/）。

FFmpeg Glitch 与扭曲效果（2025）

使用 FFmpeg 制作 Datamosh、glitch 艺术、VHS 效果、位移和创意视频扭曲的完整指南。

Datamosh 效果

Datamosh 通过操纵运动补偿来产生“像素渗色”效果。

使用 minterpolate 实现基本 Datamosh
# Basic datamosh effect
ffmpeg -i input.mp4 \
  -vf "minterpolate='mi_mode=mci:mc_mode=aobmc:me_mode=bidir:vsbmc=1'" \
  -c:v libx264 -crf 18 datamosh.mp4

# Parameters explained:
# mi_mode=mci: Motion compensated interpolation
# mc_mode=aobmc: Adaptive overlapped block motion compensation
# me_mode=bidir: Bidirectional motion estimation
# vsbmc=1: Variable size block motion compensation
强烈 Datamosh
# Heavy datamosh (more chaos)
ffmpeg -i input.mp4 \
  -vf "minterpolate='fps=60:mi_mode=mci:mc_mode=aobmc:me_mode=bidir:me=epzs:vsbmc=1:scd=none'" \
  -c:v libx264 -crf 18 heavy_datamosh.mp4

# scd=none: Disable scene change detection (more bleeding across cuts)
# me=epzs: Enhanced predictive zonal search (faster, rougher)
使用帧操纵实现 Datamosh
# Datamosh by removing I-frames (requires re-encoding)
ffmpeg -i input.mp4 \
  -vf "minterpolate='mi_mode=mci:mc_mode=aobmc',\
       tblend=all_mode=difference:all_opacity=0.5" \
  datamosh_blend.mp4

# Combine with echo for trails
ffmpeg -i input.mp4 \
  -vf "minterpolate='mi_mode=mci:mc_mode=aobmc',lagfun=decay=0.9" \
  datamosh_trails.mp4
受控 Datamosh（特定片段）
# Datamosh only certain section
ffmpeg -i input.mp4 \
  -vf "minterpolate='mi_mode=mci:mc_mode=aobmc':enable='between(t,5,10)'" \
  controlled_datamosh.mp4

色差

分离颜色通道，营造“镜头损坏”的视觉效果。

rgbashift 滤镜
# Horizontal chromatic aberration
ffmpeg -i input.mp4 \
  -vf "rgbashift=rh=-5:bh=5" \
  chromatic.mp4

chromashift 滤镜（仅色度）
# Shift chroma channels (U/V in YUV)
ffmpeg -i input.mp4 \
  -vf "chromashift=cbh=5:crh=-5" \
  chroma_shift.mp4

# cbh/cbv: Cb (blue-difference) horizontal/vertical

性能提示

  1. geq 会大量占用 CPU——请谨慎使用，或仅用于较短片段
  2. minterpolate 速度较慢——可考虑先降低分辨率
  3. lagfun 会累积效果——可能需要定期插入“重置”剪辑
  4. 先在较短片段上测试，再处理完整视频
  5. 硬件编码——应用效果后，最终编码时使用 NVENC/QSV
# Process effects, then encode with hardware
