Is this because I'm using an image sequence? I don't see much info re -framerate in the ffmpeg documentation. What's the main difference between -framerate and -r?

Do you mean that I don't need to specify the framerate of the ouput as I've declared it for the input? Would this command be ok?

ffmpeg -start_number 867116 -framerate 24 -i /Volumes/Stardom/glitch\ tests/untitled\ folder/%06d.dpx -vf "scale=720:576, crop=in_w:in_h-32" -c:v v210 /Volumes/Stardom/glitch\ tests/untitled\ folder/ffmpegv210reseiz24cro32pxcrope.mov

Thanks for your help, Carl. I've tried to fix my quoting (manually).
