OT: NIKON enters the video battle field.

Quite a demo film too. https://www.youtube.com/watch?feature=player_embedded&v=dCQ9ME2OLw8

Anxious to see how good it is recording into something like the KiPro – will it be a game changer or another nice try at video for Nikon? Hoping for the best…

I wonder how it deals with the “line skipping” that DSLRs have to deal with when recording video which results in aliasing and moire.

Have you watched the video I linked? Not much moire and aliasing apparent in the 1080 version of it, I know it’s a promo but there are some shots in there that a 5D would have problems with

Just me, but I don’t trust promo videos since they deliberate skirt issues and/or know how to shoot around limitations.

I’m looking forward to some “real world” testing by human DPs.

Craig,

I thought the crop feature on that camera looked interesting in that it seems to imply that at full crop there is no line-skipping. That might be over-interpretation on my part but I immediately wondered about the implications for moire. (Certainly not an ideal solution, but it is the first thing I thought of).

No need for lines skipping having a good processor.
Moire is a different issue and can be only avoided by reducing horizontal definition in the areas that produce it.

I think we’re done with line-skipping. The GH2 has a better way to downscale the image information from the sensor, I bet the Nikon has something similar, and I bet the next generation of Canon DSLRs won’t have that issue either.

As a complete ignoramous here will somebody describe and explain line skipping to me. I have no experience of editing DSLR material.

The sensors on DSLRS are much larger (more lines/pixels) than would normally be used in 1920×1080. So the “real time” way to downscale in camera for video was to skip lines. That would be havoc for diagonal lines or subjects with fine patterns. The tech challenge is how to design a camera that can be used by still photographers who need frame sizes much larger than video and, at the same time, allow for clean real time downconversion for video HD frame size.

If Nikon found an answer I’d love to read about the explanation. It could be filtering for example.
