[FFmpeg-user] fixed size cropping rectangle, moving in time

[Sub Phil]

Hello,

I wish to have a fixed size cropping rectangle, that changes its x-position
after say 15 sec for an initial x position of say 200 to 100.

Do I miss some quotes??

First attempt:

F:\>ffmpeg -i timeC.mp4 -vf
"crop=in_w-700:in_h-100:if(lte(t,15),200,100):80" -an -c:v libx264
-preset:v ultrafast "test.mp4"
