More 4K X70 footage at DVinfo.net

Some more variety in better lighting.

Very nice! I could only view the footage at 1440p though (limits of my system).

Very little moiré or aliasing, and you have to be purposefully looking for it. I guess that's not too surprising though since the sensor is in between "4K" and "8K" (I'm assuming the sensor reads a bit more than 3840 pixels along the horizontal, then scales down the image).

Thanks. When I viewed this on a 4K monitor I saw no moire or aliasing, BTW.

Why are there black bars all around the video?

It was rendered in 4096x2160. X70 can only do 3840x2160 so rendering in 4096 adds black bars on both sides. Scaling 4096 down to 16x9 then adds 2 more bars top and bottom.

In simple words: RENDER 3840 to solve this.

Correct. I wanted to see this in 4K 17:9, not UHD 16:9.

BTW, I have observed no rolling shutter with the X70 unless you're going nuts with the camera, wildly swinging it back and forth. I rarely shoot like that...

That's been my experience as well and that's the reason why I stayed away from the FDR-AX100
