Do you not get a REC message in the top left corner and a time elapsed box top right? Do you get a REC symbol with a diagonal line through it? What mode are you in? Unfortunately my camera is at home and I'm not so I can't check but I believe from reading the manual that video only operates in the PASM modes. The only two other things I can think of are to check that you're either in 'A' or 'M' mode and make sure, in the settings menu, that you're set record movies at 24 fps - the way you're trying to record movies should work as long as these other two things are set correctly!
Cheers, Jeff. Sep 23, Page 50 in the manual. The most likely reason is you have not focussed on anything. Last guess. Got enough room on the memory card? Beyond that - if you have followed p50 - it is a mystery.
The only thing the manual says is "Shooting can not begin until the camera has focused" - maybe you have to hit the OK button while focus confirm is active. Sep 24, For a camera-mounted mic, there's not much else the engineers could do: The last thing you'd want in this case would be a mic with limited far-field pickup.
Given that most users will likely be using the D90's video recording for short clips of memorable moments, its tendency to pick up every sound is probably a positive feature. Rolling Shutter Artifact "Jello Effect" There was one aspect of the Nikon D90's video that we found less than wonderful, though, namely the way its progressive data readout from the sensor chip can produce distortions in the image when the camera or subject moves suddenly. By contrast, most camcorders grab each frame at a single moment in time, with all of the pixels in the image acquired simultaneously.
The consequence of this progressive capture is that any movement of the camera or subject between the beginning of a given frame's capture and the end of it will produce distortions in the shape of the image.
We first noticed this effect when panning rapidly to follow fast motion: Trees and buildings would lean opposite the direction of our panning. On the other hand, if you're panning slowly to take in a larger scene, you're not likely to notice the effect at all.
More disconcerting, once we became sensitized to the phenomena, we noticed our video subjects "jiggling" slightly in response to even fairly minor camera shake as we were hand-holding the D Lens-based IS helps with this somewhat, but we'd be much happier if Nikon could figure out a way to grab the image data all at once and then read it off to the memory card before starting the next frame grab.
Video Examples: Dave shot some examples of video with the D90, so you can see what the different resolution levels look like. Click on any of the thumbnails below to bring up each video in a new window. As noted earlier, the Nikon D90's video imagery is not only considerably lower resolution than its still images, but the heavy JPEG compression applied to the video frames further reduces detail.
The upside of this is that the effective depth of field is quite a bit greater than you'd find in its still images at similar focal length and aperture. Note in some of the shots how little the apparent focus changes as wonder-dog Charlotte runs toward or away from the camera.
In the highest-res shot above, the lens was initially focused somewhere between Marti and the camera, so she's a little soft at the start of the clip. That said, I found it quite surprising how little apparent sharpness changed as Charlotte ran approached and receded from the camera. Jello Effect Rolling Shutter Artifact Rapid camera motion can result in pretty severe distortion and apparent subject motion. As mentioned earlier, the Nikon D90's "rolling shutter" can introduce pretty severe distortion in response to either camera or subject movement.
The clip above is an extreme worst case: You'd probably never film with this kind of extreme camera motion, but it illustrates the nature of the problem pretty clearly. Notice how it's really not noticeable when panning slowly. Notice too, though, how even relatively minor hand movements at the end of the clip still create some distortion. I didn't have much time to devote to sharpening my focusing skills with the Nikon D90 in video mode.
Nor, for that matter, my skills in tracking small, rapidly moving subjects. Nikon D Video Tweet Share. You wouldn't pan like this, but notice how even normal camera shake translates into subject jiggling.
In practice this bears-out with the D DSLRs also have the flexibility of interchangeable lenses, allowing you to film with exotic models including fisheyes and long telephotos, or those with macro or perspective control. Try doing that with your camcorder. Now for the bad news. It takes some practice to get it right, and ideally requires a lens with a very smooth focusing ring and distance markings.
If you buy the D kit, you may be surprised to find its video footage actually suffering from greater noise than your camcorder under low light. So under the same light, a camcorder could be operating at a low sensitivity, while the D could be pushed to a considerably higher one.
If both cameras were operating at the same sensitivity, then the D would deliver cleaner results, but with the kit lens, the Nikon will almost certainly be working at a much higher sensitivity and effectively lose much of its advantage. This is a well-known issue with CMOS sensors with rolling shutters which record each frame from top to bottom before returning to the top again for the next one. Should the camera or subject move during this process, the image can appear to tear, skew or wobble.
Now many video cameras, both amateur and professional, employ CMOS sensors, but some suffer more from this effect than others.
