Hi Guys

I particularly looking for some information from some of the folks at DJI

I am wondering why the 120fps crops into a smaller frame on the Phantom 4. It would be nice to have full frame 1080 120fps but im assuming there must be a reason for the crop

Thanks

Yes, you are right. 120fps is cropped. And also it lose data quality. For example 1080p/25fps is about 25mbit/s, 1080p/50fps is about 40mbit/s but 1080p/120fps is only 12.5mbit/s! It is really too low.

Also there is a problem about frames - video comes out of Phantom already slowed down. It hasnt all those frames in it.

i read a few times that  its not full hd? or scaled down to 720 or is really 720 or something like that. is any of that true?

It is about what you call "full HD". If you mean 1920x1080 dimensions than yes - Phantom 4 shoots 1920x1080 120fps videos. But it has very low bitrate, it uses only crop of the sensor and video is not saved as professional cameras (like Alexa, Red etc.) do.
