Really well done It's great to see Nikon pushing past Canon. The upcoming 1Ds4 should be incredible.

There was a barely noticable pattern to the CEO's shirt that went beserk on the 7D and was completely unusable.

Yep, these are fiddly cine camera's, not video workhorses. It wonderful to have a choice now. We've had competent reasonable cost video for many years now. Do you want a temperamental race horse or a well behaved plow horse?

Yes, I don't think I would feel comfortable showing on a job with just one of the vDSLRs. I am looking at incorporating these into my work, but will always have a "video" camera around just in case a "weakness" is encountered.

I am enjoying the testing, very happy they are doing it and think it is pretty effective marketing for Zacuto.

And I agree, they are showing the best side of the vDSLRs. But maybe that is the only way they should be used, pretty much like a motion picture treatment, and not a video role.

I'm enjoying watching the videos.

But...

Kind of bugs me they don't seem to be using res charts for their resolution tests (in pt.3). They're just going to blow up parts of existing footage they shot. That's kind of the first thing they're doing that I'm much less than impressed with.

And, I agree that they should do some high-speed motion and camera pans, etc. If this is really a "shoot-out," why not? It would be HIGHLY educational to see the comparisons.

I do look forward to the green-screen stuff.

Overall, I think they are doing a good job, and a VERY good job adding to hype.

Put your glass down and don't drink too much Zacuto cool-aid.

All these tests are meant to show the strengths of the DSLR's.

The third test is going to focus on color and chroma keying.

The big achilles heal of these cameras is the morie/alaising and rolling shutter. These are MAJOR problems, yet they are not addressing them.

I can understand it, because Zacuto makes money selling DSLR accessories.

Like I said earlier, don't drink too much kool-aid.

I love these little SLRs but please.....

At 1:22 on the second video, you can see the jello brick walls, it is a shot with Phillip Bloom in their studio. This is the kind of ridiculous nonsense these cameras do, I certainly hope will be covered. Stu has been vocal about this kind of thing (and the aliasing issues), hopefully the whole thing wont be glossed over in the attempt not to hurt the feelings of anyone.

The lightbulb on 35mm Kodak is so superior I don't know where to start.

The other problem is looking at these files on small screens. If they could split screen the ISO's it might help for us web viewers, I can't always see the difference on a laptop. Especially when I know there is compression involved for web delivery.

Ive done some green screen stuff with the 5DMK2 and it actually came out pretty good, so I dont expect that that camera will fail terribly, even with the heavily compressed 4:2:0. The Nikon and Panasonic are lousy, I cant believe the banding of the GH1, horrendous.

One thing that I though was really interesting was that Nikon noise reduction. The problem at least to me, with video noise is the discreet patterns of the noise, which are much uglier than film. If they can build algorithms that deal with these patterns, digital will really make some leaps if they can randomize and desaturate the noise.

That and please deal with the darn highlight rolloff, to me that is the dead giveaway of video.


Another thing I did not quite understand was the concept of upping the ISO, and leaving the lens wide open at f1.4. If I were shooting in low light, I would love that I could bump up the ISO (aka gain) and stop down to something like f4 or 5.6. I dont know what anyone learned by allowing the highlights to become 3-4 stops overexposed. You would get a true feel for the video noise performance by looking at a shot with a correct exposure.

Some of their noise, in the area of the frame that which is supposed to be pure black, is exacerbated by the radical over exposure of the video. I don't see how using a radically incorrect exposure teaches you anything, much of that shadow noise would be crushed.

Yep, the DSLR's can REALLY burn you. For me, moire pops up where you don't expect it and then sometimes does NOT show up where you would expect it. Temperamental little bugger.

I am not in the habit of drinking anyone's cool aid. I have come across the limitations of the 5D in practice so I have no illusions about the camera. I don't own any Zacuto products and don't have any plans to buy any, and yes, I can see how this is good marketing for Zacuto. However, having said all of that, these are still very professional comparisons and well worth watching.

Is the chroma key test published? Or upcoming?

The trick is to learn why and how that occurs so you can be in control.

I am guessing there will be a lot of surprises on that. I was surprized about two weeks into having the camera (5D), when I shot a promo for a contest. Now I am not saying we shot it perfect, and that there aren't some problems, but we shot this in a quick set up in my garage and with the screen to close, and with all the wrong light, and I pulled the key in Vegas.... As a result I am pretty sure there will be good results from their test. Here is the promo:

4k projection???

Did I hear the video right (I believe they said) that the 5D et. al. were comparable to film on the 40 foot screen?

Were the DSLR videos up-resed to 4k for 4k projection alongside the film clips? Did they use a 4k projector?

I agree completely.

Zacuto has maybe another year before the market tanks. His stuff looks cool, works relatively well but is terribly overpriced. With enough of this kind of promo he'll make a lot of money in the next year.

Then the real changes in the market will begin:

No, it was a 2K environment:

"The test results were projected in a 2K theatrical environment at three screening locations: Stag Theater at Skywalker Ranch, LucasFilms Ltd., AFI (American Film Institute) Theater in Hollywood and the FilmWorkers Astro Color Timing Theater in Chicago."

Then to me a 4k projection test would be very interesting.
