A video alternative to animated GIFs

I wanted to do something like my previous post, but using a video format instead of the ancient .gif format. Here's what I ended up using:

ffmpeg -ss 00:04.20 -i in.mp4 -t 00:06.30 -an -vf "crop=1668:1668:1292:10, scale=480:-1" out.mp4

Options:

• -ss 00:04.20
  Start 4.2 seconds into the input file
• -i in.mp4
  Specifies the input file
• -t 00:06.30
  Limit duration to 6.3 seconds
• -an
  No audio
• -vf " ... "
  Specify the filter chain to operate on the video
• crop=1668:1668:1292:10
  Crop out a 1668 (width) x 1668 (height) window, with the top-left corner located at x=1292, y=10
• scale=480,-1
  Rescale to width=480, height=auto (preserving aspect ratio)
• out.mp4
  Specifies the output file
