A few tidbits on that FB thing, but I will look forward to some real world cinematographers putting both the D800 and D4 through their paces. :-D

Re: Nikon D800 with video features
 

Since my last posting in which I was asking if there are any differences in the quality of the video between the D800 and the D4, I have since changed my mind. I cancelled my D800 order and went to the D4.As yet there is still no definite distinction of video quality between these 2 camera's, I know I would have an inferior stills camera in the D800 to the D4. In the tech specs that Nikon issued on how to shoot stills with the D800 did it for me. It was all about motion blur(should use tripod) and not recommended to stop down past f8, all due to the mega pixel count. Not what I wanted to hear, not the way I shoot stills. Thanks for the previous postings, alway's listening in to your comments.

Re: Nikon D800 with video features
 

Excellent point Jerry. I didn't pick up on it. It makes sense that if a sensor has as many more photosites as does the D800, that tiny movements or vibration (caused by any number of things, from shaky hands to wind) will present huge challenges in deriving a sharp image. At this point it's conjecture, but I think you made a good decision.

Re: Nikon D800 with video features
 

Jerry I think you're forgetting that the apparent sharpness of the image is all relative to your viewing size.

The issues of vibration and diffraction affecting the sharpness of the D800's image is only at the per-pixel level (i.e. 36mpx viewed at 100%).

Viewed at the same size as images from the D4's 16mpx, there will be no apparent lack of sharpness or detail in a D800 image shot the with the same level of vibration or diffraction as the D4 - even if, at the pixel level, some of that detail has been smeared.

So the resolution doesn't present any real issues for the image, it just requires more precision if you want to get the absolute maximum out of it (on a pixel level).

Can you more thoroughly explain why so, because on the surface it might logically appear that more smeared pixels - millions of them - would produce huge issues in processing a sharp video image.

That said, I'll leave this to the sensor engineers.

Re: Nikon D800 with video features
 

It's good to hear this(Mark Kenfield's reply) because I'm no tech guy. It's too bad I don't have a camera in my hands to do my own tests.I haven't seen any stills samples to date shot with the D800 or D800e that have blown me away. I still think the D4 is a more solid camera for stills shooting, and probably a little better in video as well, more features anyway, could be wrong.My problem is that I have some large shooting assignments starting this spring , half of it is video, and I would like to be shooting it with a new camera(1080p,8 bit 4:2:2). And then again, will these camera's be delivered on time.

Re: Nikon D800 with video features
 

Try to think of it in terms of pixels (I'm exaggerating the effect here, but it should make it easier to understand):

Here's two versions of the same image, the left-hand version is half the resolution of the right-hand version (hence the larger pixels when viewed at the same size):

http://i.imgur.com/VcmxW.jpg http://i.imgur.com/iaPBo.jpg

Because of this difference in pixel density/detail, even if the full-resolution version were to have a substantial smearing of it's detail on a pixel level (due to vibration or diffraction), the amount of detail resolved would still be at least as high as the half-resolution image with it's much larger pixels.

Re: Nikon D800 with video features
 

Hey Mark, forget about the stills for a moment. Between these 2 camera's(D4,D800), same size chip, same features, one 16 megapixels and the other 36. Does one have an advantage of better video quality over another. Did I say that right.

Re: Nikon D800 with video features
 

Without knowing how the HD image is extracted from the sensors, it's impossible to say at the moment. We'll just have to wait and see some raw footage to see how they compare.

Re: Nikon D800 with video features
 

Great fashion video shot with the D800

Re: Nikon D800 with video features
 

Funny but at the end of the video it says 2011...


I have one question for the forum. As you know D800 can shoot at 20mp and 9mp without cropping. Does that mean that the low light performance improves?

Re: Nikon D800 with video features
 

The footage looks good, but as one person remarked, "Where's the shadow detail?"

A) It's on those cam that cost $20K and up.

But seriously, I am wondering about HDMI output and whether what we see in the current examples is a codec crushing the blacks to save space. I hope so and that the HDMI retains good looking shadow detail.

Re: Nikon D800 with video features
 

Well, talk about an oxymoron - an 'uncompressed' D800 video test on youtube,
Michael Pappas posted this link on the CML list.

NIKON D800 HDMI V.S AVCHD TEST VIDEO Vol.01? - YouTube

It shows something, but I am most interested in highlight and shadow capabilities of the D800 when recording HDMI out.

Re: Nikon D800 with video features
 

Interesting that higher bitrate footage often shows more of a detail gain than "color" improvement although the color sampling is what gets the attention.. Also interesting how the HDMI footage had a brighter exposure. (assuming they were shot at the same time).

Re: Nikon D800 with video features
 

I am hoping that someone will soon test the D800's HDMI out in a 'real shoot' situation involving high contrast and lots of shadows. Chip charts have their place, but I really want to see if the D800 can make art.
When I know that the HDMI out is truly clean and enables shadow detail normally 'thrown out' during in-camera compression, my next step will be to round up the money to buy one.

Re: Nikon D800 with video features
 

Chiayi Fun,

your great video has caused a revolution already all over DSLR forums worldwide. It's been the first video showing the D800 might have a resolution approaching that from the FS100/F3, and way beyond what the newer 5DmkIII is capable of. As it's also relatively free of artifacts and shows a great Dynamic Range, the D800 might end up dethroning Canon in the DSLR video camp.

Would you care to comment how did you shoot that video, what your D800 settings were, was it a simple CS5.5 edit with no other processing, etc?

Re: Nikon D800 with video features
 

It is a very nice image. I really like the absence of the crushed black look so common in DSLR video.

Interesting shootouts are probably in the making!

Re: Nikon D800 with video features
 

As a note of caution, that link seems to solely be looking at the D800 from the point of view of stills performance. It would be totally wrong to draw any conclusions from that either way about video performance.

Nikon D800 customers may face UK delays through April (latest update 27th March):

Nikon D800 customers may face UK delays (update) news


I'm also concerned about the sudden £200 leap in price...and even larger increase with the D4!

http://www.amateurphotographer.co.uk...ws_311965.html

Re: Nikon D800 with video features
 

I wonder, the price hike was due to a system error, as they claim, or due to unprecedented demand?

Re: Nikon D800 with video features
 

There is no real excuse for this 'blunder' by Nikon. UK buyers are already sending shock-waves...and cancelling orders.

Mistake leads to Nikon price increases [update 2] - British Journal of Photography

To say that it was a 'computer error' is ridiculous.

As Thom Hogan remarked: "...The net overall price increase just made measures out to a bit over 10%. Hard to figure how you miss by that much and not notice it somewhere in your organization the first week, let along the second, third, fourth, fifth, right up to the 11th week.

But wait, they did it twice. The D800 was also changed in price this week by Nikon UK. So six weeks after its price was announced, we suddenly have a realization on Nikon's part that their numbers are wrong?"

Re: Nikon D800 with video features
 

It is early days yet, but video quality straight out of the D800 is better than I expected, and far better than the video performance from its more expensive brother the D4. The D800 seems to have a slight problem with pixelated reds (although at least it has HDMI out option to overcome this). Despite that price increase, the D800 seems to be a match for the Mark III in both stills & video in most quarters. Some aspects of D800 are far better in both stills & video with the D800 far better in detail and sharpness (although this can be improved with Mk 3 in post), but out of the box the Mark III copes much better with moire patterns, and is much cleaner and relative noise-free at high ISO in extreme low light video.

Re: Nikon D800 with video features
 

But what about aliasing?

If the D800 line skips, it will win/tie on some shots and lose badly on others.

Re: Nikon D800 with video features
 

A few issues are beginning to show with the first batches of the Nikon D800:

I'm not sure yet if Nikon are going to correct the problems on the cameras they have yet to export, or will deliver Firmware updates to those who already have the early Nikon D800 bodies.

Re: Nikon D800 with video features
 

Hey Tony,what do you like better in the video qualities by the 800 as to the D4, and how much better is it.

Re: Nikon D800 with video features
 

The video out of the D4 is less detailed than the D800, but then again it has slightly less problems with moire patterns. For some reason the D800 is cropping the video frame more than the D4 when using same lenses. I haven't got both together at same time to test this out at the moment, so maybe someone who has can double check this for us and post their findings.

Re: Nikon D800 with video features
 

Hey Tony, I originally ordered the 800, then changed my mind and ordered the D4 only because the D4 for stills is more suited for what I shoot. I thought the 800 and D4 would be equal in the video features and now I'm hearing the D4 is not as good as the 800. I still need it for stills, I'm hoping the video is good enough for what I need for I may have to get the 800 down the road as a second body if I'm not satisfied with the video quality of the D4. All these reports are making me nervous. Thanks for your reply, if you find out any other info on either camera, please fill me in. thanks, jerry JLM

Re: Nikon D800 with video features
 

Jerry I actually think that the D800 produces slightly better stills than the D4, but the bigger brother's more robust build qualities, tighter seals with no inbuilt flash, faster drive and better battery life may fit your kind of work. The D4 is still no slouch in the video department either, so I'm sure it will fit your requirements without having to fork out for an extra D800 body.

I love some of the work on your website by the way, and that colourful opening image is certainly eye-catching.

Re: Nikon D800 with video features
 

Mr. M. Pappas, long time Watchdog hero, has passed along some URLs on the CML of the D800 including a lot of bricks and tiles footage, which deliberately tries to show some of the worst case scenarios of moire and jello cam.
From what I can tell from these, I know I can work with the D800 and turn out some killer images.

5D2 Plus D800



Another of the D800 moire...

Re: Nikon D800 with video features
 

Yeah, the 2nd video is pretty bad, but I wonder if HDMI were used and we could view it on a real monitor what it would look like. That said, I know not to use that place or anything similar as my set.

Re: Nikon D800 with video features
 

HDMI isn't likely to improve moire.

It looks to me like the Nikon's smaller grid allows better co-siting of the luma and chroma pixels than the 5D2. The 5D2 doesn't just alias, it does so with the green, red, and blue pixels at different phases. When one color disappears between the pixels of the 5D2, another color nears its peak.

I shot video of a number of people in various shirts, jackets and sweaters yesterday with the 5D2 and VAF. It was a joy to nail the focus and not have a hint of aliasing. :)

Re: Nikon D800 with video features
 

Jon, what is the widest lens you've used with the VAF?

Re: Nikon D800 with video features
 

The 35L and ZE 35/2 work great. The 16-35L II is pretty good to about 30mm. It's hard to identify a specific cut off point. The ZE 21/2.8 is a fail. I haven't tried the 24L, but would love to see how it holds up.

I've now used the VAF with the 16-35L II and the 70-200/2.8L IS II. Both are near parfocal without the filter and are wildly non-parfocal with the filter. With (this one copy of) the 70-200 you can go end to end and you just have to nudge the focus a bit. Add the filter, and I was turning the Redrock FF by nearly 90 degrees to compensate for the zoom. Needless to say, I did no live zooming - especially since you often need to pan/tilt to hold the composition. I can't pan/tilt, zoom and focus at the same time! Without the filter, I would zoom, then nudge and hope that nobody noticed. :)

I think the VAF adds field curvature. That's partly why wides don't work well. It's not just soft out there, the focus plane simply isn't flat so the corners are out of focus.

That said, if you are super close to a small object with an ultra-wide at a wide aperture, it might work as the corners would be blurred due to shallow DOF anyway. But this would be a rare shot.

Re: Nikon D800 with video features
 

Thank you for that info, Jon.
