Can I reduce the bitrate by cropping the video?

I have a question regarding the H.264 encoding using iMX6/VPU.


The original size of the video is 1920 x 1080, but the sky area is not necessary.

If we remove the sky area using "int avc_frameCroppingFlag" of "EncAvcParam" at the encoding, can we reduce the bitrate at the same picture quality?


Sorry for my primitive question because we have just started investigating the possibility of using iMX6 for our products.


Thanks in advance for your help.
