D90 & Movie Mode
"ASAAR" wrote in message
... Just found an amateur clip. Image quality looks OK. (http://guykawasaki.typepad.com/DSC_0018.AVI) (32MB) You are however limited by 6 minutes of recording in HD. Also, the focus locks during recording, which is a bit of a shame, especially if you are using a big aperture lens. Rarely is more than 5 consecutive minutes of video really needed. If shooting your own personal documentary, the next 5 minute clip can be started almost immediately, or by shooting at less than HD resolution, longer clips are possible, up to the same 60 minutes according to the D90's manual. Also, are you sure that the focus locks? You may not be able to have the camera AF but MF should work, sacrificing convenience for control. Depending on the lens, many should also be able to override the lens's AF switch position and focus manually while shooting video. You are quite right with both of your comments. But, why have a 6 minute limit? What if for example you are shooting an interview, a speech, a music/theatrical scene, etc. or even a 'special' home movie? Why the restriction? Surely it's not to allow the sensor to cool down if you can start recording again immediately? Yeah, poor choice of words with saying lock. Of course you can manually focus, but again not very good. I would be quite an art zooming and manually focusing your kid playing football for example, especially if you are using a fast lens opened up. Yeah, I know, it's not a video camera, but would be nice if they thought about the above two limitations more. |

D90 & Movie Mode
"Jeff Heyen" wrote in message . .. Guys, I've read a couple of opinions on the movie mode included in the new Nikon D90, and that many expect this to be a feature common to dSLRs moving forward. The opinions center on increased use of movie mode by action photographers, and editors then picking out the ideal photo from the movie clip. Knowing less than nothing about the movie mode, will this be a practical application for the amateur user? So we can have a fuzzy 21/2x31/2' photo for news? (1280 x 720 pixels) frame capture. |

I don't know how accurate it is, but I've read some accounts in the DPR forums that at this point the file size reaches 2GB, the maximum "safe" file size limit for many computers. Nikon could have used common techniques such as continuing to shoot, using as many 2GB files as needed for a single video (the Zoom H2 does this for large audio files), but maybe Nikon has that single file limit to make the non-pro D90 "idiot proof", so an inexperienced user doesn't completely fill their only 4GB or 8GB card with a single relatively short video. You're right about it probably not being a heat restriction, as some there (DPR forums) that have measured sensor temperatures (one buys sensors used in cameras that he's designed for other companies) show that sensors don't significantly warm with extended use, typically using only about 1/10 the energy used by the LCD display. |

Surely it's not to allow the sensor to cool down if you can start recording again immediately? the sensor does not heat up. someone on dpreview used one of those infrared temperature measuring devices after using live view for over an hour on a d3 and found no significant change, nor any effect in the images produced. furthermore, if it really was due to heat, the camera would block the user from taking a second 5 minute movie immediately after the first, and it would also limit live view to no more than 5 minute intervals. the real reason is that a 'video camera' is taxed differently, so by limiting it, it doesn't qualify as a 'video camera.' |

Ah, didn't think about that. Not good from a user point of view, but this makes sense. |

I remember ordering a camera from the US and apparently the duty you have to pay is different if you buy a body compared to if you buy a body with a lens. Something like that anyway, I let them sort it out to be honest, so can't really remember. That said, I think that the file size limits of the OS are the real reason. |
