Nikon D90 has 720p24 over HDMI

I think the catch is that the shutter speed can't be locked (manually selected) so the auto exposure will keep shifting as the scene changes or the camera moves.

You could put an older Nikon lens on the front and have control over zoom, focus and iris just like we do now with adapters. Looks like my rig might be going into the trash. I needed to upgrade my SLR anyway. Now looks like the perfect time.

Still want to see some raw shots but I don't see how the adapter manufacturers can compete with an SLR that takes video.

If my calculations are correct it will be about

16mbps at MotionJPG 1280x720 24p

13.56 mbits/s


[EDIT: just noticed you have updated with the actual data rate !!]

Subject was not moving, worryingly the effect is most prominent when the camera and subject at pretty much still.

My mind is blown. This kicks my HF100's ass. I'm definitely a Canon guy, but I'm selling my 40D asap and preordering this. I understand it isn't 1080p, has an outdated codec at a low bitrate, but honestly, I doubt me or any other person using this camera will need anything more. I can finally carry just one camera around to parties/shoots/gigs/whatever.

Also, the D90 can provide ridiculously high "noise-free" ISOs up to 6400 (compared to about 500 for the red one, roughly 3.5 stops faster)

Btw, Ken Rockwell gets that this is a big deal for filmmakers: Nikon D90

Ken is funny. Do like his opinionated (but in a good way) stuff...

The bad news is that you have a 5 minute limit on any shot and you have to allow for the sensor to cool.

An individual shot can’t be longer than five minutes in hi-def, either, or 20 minutes in standard definition; after that, the sensor heats up too much. So don’t expect to film the school play on this thing.

Worst of all, the autofocus doesn’t work for video. You can autofocus before you start rolling (half-press the shutter button), or you can use the manual-focus ring while filming. But those are kludges; if the distance to the subject changes while you’re filming, moments of blurriness are inevitable.

Otherwise, it's still a very interesting camera...

CAn I confirm if this is a typo ?? It says 480P. 720P and 1080i on the HDMI output.. Why would someone add just 1 interlaced video mode to progressive still and 2 other video modes ??
CAn it be 1080p sent within 1080i ?? i.e. A signal that needs pulldown to extract 24P ??1080i ??

[Chris Hurd]

Because 720p and 1080i are equal to each other in bandwidth. Same amount of data either way.

I had a quick play with the D90 video mode yesterday, I was very impressed. Auto focussing before filming starts is cool, much like the way we used to use push af on Z1's The screen is bright and clear, but really could do with a tilting option. The lens effects are as good as I get with my Brevis setup. Not sure about the codec, time will tell. I already have an Edirol R-09 audio recorder so I aim to use that for sound. A HDMI field monitor will be the next step.

Also had a chance to play around with it on my Red Rock Micro rig and a Manfrotto modosteady. All good fun. Can't wait to get one.

I did a short video (shot on an EX1) of the camera here YouTube - Nikon d90 launch event
but it doesn't show the video mode as it wasn't been publicly demonstrated.

A word of caution for those hoping to use a flash XDR or similar HDMI capture device, current Nikon's I own (D3, D700 and D300) all push the entire screen with overlays and focus points out on HDMI and can't be turned off. I wouldn't be surprised if the D90 was the same.

The other downside is there does not appear to be LANC or any other video trigger other than the button on the camera back. This could be a real pain in many rigs.

Hope this is of help.

In video mode, can one set the shutter and iris manually?

Thanks for posting your results. I'm getting soft results on my redrock micro M2 with a Sony EX1, either with nikon 28/50/85 f/1.4 lenses. The sides are just too soft. So, given that is the best the EX1 can do, I'm wondering how you would compare the D90 video quality to that of the EX1+RedRock?

As for video trigger, is it possible to use an infrared controller? When the movie mode makes it into higher end cameras, we hope to be able to use remote trigger cords or computer camera control.

[Kurth Bousman]

didn´t I read the d90 has a corded remote ?k

[Kurth Bousman]

it´s called mc-dc2 - see pg 3 of the dpreview handson-k

[Dan Chung]

The D90 can use this MC-DC2 Remote Cord from Nikon
but it only seems to be a trigger for the shutter button, the video is started using the OK button when in Live View mode, not the main shutter release. Maybe it can be configured in some other way using custom functions but I don't think so.
