    Hi everyone.

    I need to crop a video from all sides (top,left,bottom and right), but there's a different # of pixels i need to crop from each side.
    I usually use VideoRedo,however this time the cropping has larger number of pixels and it takes around 10 hours to finish it,which is a bit too long (my CPU is intel i7,btw).
    I know ffmpeg can do it with "crop" filter:
    Code:
    -filter:v "crop=out_w:out_h:x:y"
    out_w being width,out_h being height, x&y specifying the top left corner.

    However i can't figure the correct input in this filter. I need to crop: left:342,top:206,right:286,bottom:176 (this is what i had in VideoRedo window)

    I also tried HandBrake,however it also takes up to 10 hours to finish the job

    Let FFmpeg do the math for you.

    in_w-342-286:in_h-206-176:342:206

    It's just a little simple math: After cropping the remaining width of the image is in_w - left_crop - right_crop, the remaining height of the image is in_h - top_crop - bottom_crop, and you want the top left corner of the crop at left_crop, top_crop:

    Code:
    -filter:v "crop=w=in_w-342-286:h=in_h-206-176:x=342:y=206"
