Solution

  • The select frame notation would be [N] immediately after the filename; where N is the frame number you wish to select. See Selecting Frames section under the input filename examples. 

    mogrify -resize 80x80 \
        -background white \
        -gravity center \
        -extent 80x80 \
        -format jpg \
