[FFmpeg-user] Faster way of cropping video?

I've been cropping a number of mp4 videos with ffmpeg but I was just wondering whether there is a way of doing it that doesn't involve re-encoding.
I've been using a command like:
ffmpeg -i "Gopro1.mp4"  -filter:v crop=iw-300-20:ih-0-180:300:0 "Gopro1_crop.mp4" 

Which works by cropping a 1920 x 1080 video to 1600 x 900 

But just wondering if there is a quicker way.
