See https://superuser.com/questions/1087685/ffmpeg-zoompan-image-to-center-position

Hi,
When I tried the script or the standalone full command I got this error:
[Parsed_zoompan_3 @ 0x2504060] Option 'fps' not found
[AVFilterGraph @ 0x24ff960] Error initializing filter 'zoompan' with args 'z=if(eq(on,1),1,zoom+0.000417):x=0:y=ih-ih/zoom:fps=60:d=60*4:s=1280x800'
Error initializing complex filters.
Option not found

Any ideas?

forgetting the output file will overwrite the last picture in the list.
i.e. only overwrite if the destination file is not a picture else warn "this will overwrite picture %s, you should give an output file"
Or force to pass output file via an option "-o"
