Re: Clips from the NAB camera set.
I concur with David that with a good downconversion algorithm you should not get any aliasing. One advantage of shooting at 4K and down converting is that you should end up with better micro contrast at HD than you would with a typical HD only camera as with an HD camera the optical low pass filter will be reducing contrast before you get to the resolution limits of the camera to minimise aliasing. Optical filters don't have sharp cut-offs so contrast reduction close to the cameras resolution limits are to be expected. However if you start with a 4K image then the electronic filtering in the downconversion which should be more precise than any optical filter should result in better contrast. Sony's F65 with it's 8K sensor produces beautiful 4K images and ultra impressive HD with incredible detail close to the resolution limits because of the over sampling and software anti-aliasing.

Re: Clips from the NAB camera set.
Just a quick FYI. For those that are interested Philip Bloom now has a taster of his forthcoming FS700 review up on his site along with a slomo video shot in Brighton. His full FS700 review is coming on Friday.

Re: Clips from the NAB camera set.
And I have just seen on Alister's blog that he now has a FS700 to review too, amongst some other new cams!
The next few days/weeks should prove interesting! |
Re: Clips from the NAB camera set.
Yep, reviews of the FS700, PMW100 and NX30 coming soon. Love the little NX30, but can't stop shooting super slow mo with the FS700, it's highly addictive!
