The text, putting on image is splitted on two blocks: top text and bottom text. To add line to top block, use -t option.

./ffmemepeg -i example/osaka.png -t "TOP TEXT" -f Impact

Several lines of text can be added.

./ffmemepeg -i example/osaka.png -t "TOP TOP TEXT" -t "BOTTOM TOP TEXT" -f Impact

For bottom text, use -b option.

./ffmemepeg -i example/osaka.png -t "TOP TEXT" -b "BOTTOM TEXT" -f Impact

Top and bottom blocks have their own font sizes and margins.

./ffmemepeg -i example/osaka.png -t "TOP TOP TEXT" -t "BOTTOM TOP TEXT" -b "TOP BOTTOM TEXT" -b "BOTTOM BOTTOM TEXT" -f Impact

Font size can be changed using -S option for top block and -s for bottom. The font of whole block will be changed. The argument of size option is a reliative increase ratio: passing -S 1.2 and -s 0.7 options means increasing top block font size by 20% and decreasing bottom block font size by 30%

./ffmemepeg -i example/osaka.png -t "TOP TOP TEXT" -t "BOTTOM TOP TEXT" -b "TOP BOTTOM TEXT" -b "BOTTOM BOTTOM TEXT" -S 1.2 -s 0.7 -f Impact

Blocks also have margins. They can be changed using -M and -m options. Their size is measured reliative to image height. The default margins are 0.05 for both top and bottom blocks.

./ffmemepeg -i example/osaka.png -t "TOP TOP TEXT" -t "BOTTOM TOP TEXT" -b "TOP BOTTOM TEXT" -b "BOTTOM BOTTOM TEXT" -M 0 -m 0.2 -f Impact

The output file can be provided with -o option. The default output filename is out with input file extention.
