Step 3: Convert Video to Grayscale using FFmpeg

Here is a command to convert a video to grayscale using FFmpeg:

ffmpeg -i input.mp4 -vf format=gray -c:a copy output.mp4


  • -i input.mp4 – Input video file
  • -vf format=gray – Set video filter to grayscale format
  • -c:a copy – Stream copy audio without changing
  • output.mp4 – Output grayscale video

The format filter converts pixels to grayscale. Each pixel’s R, G, and B channels are set to equal values based on luminance.

So in summary, the format video filter can apply different color effects like converting to grayscale. Audio is stream copied to avoid re-encoding.
