How to scale recording in version 2.0.7

ADD 1-100 FILE c:/rec.mp4 -vcodec libx264 -acodec aac -vf scale=640x240 does not scale video. it gives warning “invalid option -vf scale=640x240”. what is the right way to scale recorded video in version 2.0.7

Try following command

ADD 1 FILE rec.mp4 -vcodec libx264 -acodec aac -s 640x240

it worked, thanks.
can you provide me with other parameters that works? i wanted to change frame rate , i use -r 25 but it was rejected (Invalid option)

It works despite the Caspar server throwing Invalid Option. Please check the recorded file.
(ADD 1 FILE record.mp4 -r 40)
