Nikon D7000: 1080p24 Video First Impressions:
I finally acquired another D7000 body from a local Best Buy today (5 November 2010). Earlier this evening, I shot a few 1080p24 video test clips. Here's some initial impressions (more to come) . . .
Nikon D7000 Chroma/Luma Banding: Virtually none.
Chrominance and luminance aliasing (banding) is virtually non-existent on the new D7000--good news for video with only a 4:2:0 sampling ratio (halations around light sources do show a small bit of aliasing). This is a dramatic improvement over the D90's very severe aliasing, which was/is one of the D90's worst video artifacts. The aliasing present in the D90's video makes it unusable for any serious use.
Nikon D7000 Rolling Shutter:
Rolling shutter ("jello") is less severe than on the D90, but still present, and is detectable even on moderately slow pans when used on a fluid-head tripod.
Nikon D7000 Noise:
Noise is pretty acceptable up until about ISO 800. On a Sharp Aquos 52" LCD TV, at a viewing distance of 10 feet, noise levels in motion video are nearly imperceptible up to ISO 800. Interestingly, I think the noise patterns produced at high ISOs on this camera look a little more like film grain, rather than the huge macroblock-ish, or fixed-pattern noise signatures characteristic of older video cameras. The D7000's noise pattern appears more "organic."
Nikon D7000 Stair-Stepping: None.
No perceptible stair-stepping artifacts, an "always-there" artifact that plagued the D90.
Nikon D7000 Average Bit-Rate:
At 1080p24, the nominal bit-rate averages between 19-20 Mbps.
Nikon D7000 Fluorescent Flicker:
The built-in 50Hz/60Hz flicker reduction setting in the D7000 virtually eliminates the "rolling bars" artifact from fluorescent, and other discontinuous light sources. This was an atrocious problem with the D90 that's been successfully addressed in the D7000.
Nikon D7000 Motion Video Stuttering on Playback:
All of the issues described below are playback-related, and not a result of the D7000's acquisition or encoding. Use Apple Compressor to transcode D7000 .MOV files to Apple ProRes 422 files, complete your edit sequence, then export your final cut out of FCP into a QuickTime movie. The exported QT movie will play just fine.
During a slow pan, even when using a professional fluid-head tripod, video playback can appear to "hiccup." Not to be confused with "strobing" (strobing is when a pan occurs too quickly for the frame rate and shutter speed). You'll see strobing during any pan, and it looks as is should, and isn't objectionable (unless the pan is too fast). If you're seeing micro-interruptions during a pan, or even in-frame subject motion, this is just Apple's QuickTime player struggling to play the clip on perhaps, a lesser (slower) Mac.

What initial "Easy Setup" settings should we be using in FCP?
I'm guessing this (but unsure of the codec)
Format: HD
Rate: 23.98 fps
Use: HDV 1080p24 Firewire BasicI'm in FCP now. I've found that the native D7000 .MOV clip won't play properly in the FCP timeline without first transcoding to ProRes 422 in Apple Compressor (maybe my drives are too slow). I just batch-converted all of my D7000 .MOV files in Compressor, then imported the resulting ProRes 422 .MOVs into FCP. I set the Easy Setup to "HD;" "23.98;" and "Custom Setup." Now, the clip plays on the FCP timeline without stuttering. Export your sequence out of FCP into a QuickTIme movie, and the resulting .MOV clip plays perfectly from the desktop, with no motion-related artifacts.

That first image had me scared for you, studio! I'm glad it looks like you found one that's going to work for you.

I'm sorry, I should have explain my self better. The Mac can play the files, but they skip alot, very choppy video. I have all the latest updates, running Leopard too.Yes, I'm experiencing the same issues on a more-current 3.06 GHz/2 GB iMac. I haven't been editing any HD streams in FCP on this set-up, so the stuttery playback may just be symptomatic of my under-powered system. Once I converted to ProRes, and exported the timeline to a QT movie, however, the resulting QT stream plays back fine. I do still have playback issues within FCP on its timeline, even when using converted ProRes clips. I think I have some HDD/processor/memory throughput issues which may need to be upgraded for the D7000's video.

Thanks for all the discussion, guys. I'm getting this primarily for the video function. I was so close to caving in and buying a 7D, then they announced this just in time.
So it's basically agreed the auto focus for video is pretty bad under most circumstances. Are their some conditions where it does work decent enough to use, for example in wider shots without too much depth of field, or instances where the subject is moving slowly?

Not to hijack the thread, but since you're clearly in Los Angeles, which BB did you find it at??

I almost threw in the towel and got a 7D myself after all the bad pixels I kept finding. Although I still have a couple in my current D7000 body, I'm still very happy to have the benefit of a Nikon body for all of my Nikkor lenses.

One thing that it does have is an AF delay setting, which is something I really was hoping for, and I was very happily surprised to find that Nikon had included such an "advanced" feature. You can set the delay (from when the AF function starts to re-acquire focus) from none to "long."
"Slow" AF re-acquisition was reportedly one of the "flaws" (which is actually a benefit for filmmaking) with the Sony VG10. While I'm typically focusing manually (using mostly, Nikkor AIS lenses), a decent AF-tracking function for Steadicam work would come in extremely handy. Haven't tested this yet, but I'm going to try it out later tonight.

I just finished cutting a short sequence from the footage shown in frame grabs above. Don't let the stuttery playback (depending on your system specs) of the native D7000 .MOV file fool you. Once edited in ProRes, and output as a QT file, the footage looks gorgeous. There are no unusual motion artifacts. Shot in 1080p24 at 1/50th of a second, all motion (including in-frame subject movement, pans, tilts, rack-focus pulls, etc.) looks entirely natural and movie-like. Add a double-system sound set-up (you have to synch with a clapstick) and you could shoot a feature with this camera.

The video looks to be goregous. If only it was 1080p 30fps, not 24..

I have just bought a d300s. Is it relevant to this thread?
Yes, as I need recommendations on manual primes for video.
I would like a few, but i have no money for this little hobbie, as it's all gone on good fast AF glass for stills.
I would like something wide, as DX is so cropped.
Something from 20-30mm should be good. Although preferably 20-24. I think even 28 is going to be too wide. I would like to capture a whole room. It would also be nice if it was a good landscape lens on FX. It needs to be full frame.
After looking at the nikkors quite a bit, I may be leaning towards zeiss.
I am in japan, and have many options on used glass.

I asked earlier how to embed a Vimeo clip in the forum [thanks, jonny--you can remove your link now, since the file number's changed]. I found a tutorial on how to use Apple Compressor for optimizing my file for uploading, so I've re-uploaded a smaller file and will post the new link below.

I'd like to see your clip. I think it's as easy as just posting the URL, studio. Here's a test. Here's what I'm typing (edit: I think I found your clip):

I should have been more specific... "real time" eliminates choppy and skips in playback. It's a jargon used by editors. Sorry for that.
Apple-ites will want to use Pro-res in their machines for FCP or any editor for that matter when editing for that reason.
Apple and Grass Valley for Windows trans code the CODEC from AVCDH to a proprietary CODEC for editing, Premiere Pro (CS5) and Vegas Pro doesn't, PP but does generate preview files for any content that has filters and transitions applied to them.
Faster computers will make a better editing experience.
The more you know about editing, the better your experience will be, too.
There are different broadcast standards worldwide, in the USA it is NTSC, Europe is both PAL and France is SECAM, but PAL works there, too, more or less. PAL has some variations worldwide.
My best,
Mike

So with this camera, what would be the recommended lenses for using this as a filmmaking camera?
I'm not familiar with DSLR lenses for serious quality, but the maximize the result is it better to buy a lot of different primes, or a really really good Zoom lens?

Well there are a lot of differnt lenses out there for you to choose, it all dependes on how deep is you're pocket? IF you want to experiment with video then there are some lenses that are good for one thing but not conviniance for other things.
IDealy you should have a set of primes and few zooms for quick snapy video which you need for special moment that reqwire to be quick.
For a set of primes you can always count on manual Nikon lenses, which you can pick on e-bay like a 24, 35, 50, and 80mm. You can also check for other banrds as long as they have wide apertures, again it all depents on how much moeny you have to spend.
One thing you have to bare ind mind is that if you have a D90 or D300s and want to have some control over video you must have manual lenses with aperture ring on the lens other wise you will be limited as to what you can operate.
Both cameras don't have manual control over video so they are very unpridictable to control when shooting video. I use a Nikon mount Tokina 24 to 200mm zoom lens on my D300s and it is a good lens, shame though it is only f3.5 but it did the job.
So at the end it is totaly up to you and what you can afford but one thing bare in mind that if it has a NIkon name on it it is going to be exelent even if it is an old lens.
Trust me my 24mm 2.8 nikkor is miles better then my L series C.... lens that came with 7D
Hope this helps

Getting ready to go out.. too a quick low light vid (after finally realizing what the full time autofocus mode was)
Anyway... focus movement is awful. Focus sound is awful. hmmmm

Did more filming this weekend... autofocus question..
I am having probs getting the AF to grab. I can do the initial half shutter, but shouldnt I expect it to grab into focus at taht point? I am getting frustrating results where it goes in focus then immediately out. Then 3 mins later will try again and it grabs into focus.
Any tips from people?
Posted 2 years ago # -
Doh! I just re-read the instructions.
AF-F should start the autofocus... and pressing the shutter locks the focus.
I was confusing modes and operations, and knocking my video out of focus by hitting that shutter halfway. (I thought i had to do that to start the focus, when it seems that for AF-F it actually stops the focus!)Will try again at lunch to confirm.
Posted 2 years ago # -
the af system during video hunts a lot.
hitting the shutter release button does a re-focus but when the subject moves on it will continue to hunt for focus
