Hi,

Sorry, the caret automatically went top in Thunderbird.

Here's the command:

/usr/local/bin/ffmpeg -r 1/5 -i /path/to/pics/img%03d.jpg -i 
/path/to/music/music.mp3 -c:v libx264 -c:a aac -strict experimental -vf 
fps=25   -pix_fmt yuv420p -shortest /path/to/film/out.mp4

Here's the shell output:
