HDMI output
Thanks David for the calculations on the hdmi output. Sounds like it will not be much of an advantage to pair this camera with an external recording device?

If they don't do 1080p30, it's likely that the sensor is slower than Canon's, and will likely have a longer rolling shutter latency.
Still, if the HDMI output is clean, that would rock. The only remaining big questions are how they handle aliasing/resolution, and how good the encoder is... |

David W, I'm not sure I follow you? If the HDMI does not scale its output (like the 7D does - but it's still better than SD resolution) then that would be very useful (monitoring in Full HD and/or attaching a Nanoflash or any of the alternatives we're all reading about). As was pointed out by David N (and on various other forums today) the bit rate/video encoding format is likely to be 24Mbps AVCHD. The hope is the HDMI output (i.e. uncompressed) whilst RECORDING is not scaled down from 1920x1080p (as is the case with my Canon 7D)....if Nikon have done "the right thing". Even if the HDMI output whilst recording is the real deal, I think it would be a complete overkill to attach an expensive Nanoflash (or alternatives) to this camera if the sensor still produces horrible aliasing and skew, jello etc. (all of which I've just seen very easily on the linked to videos - some "mud" too). But what do I know - especially about Nikons! EDIT, I see David N has replied about this at the same time as I posted too. |

There is also the issue of menu overlays. Is the HDMI video available clean?

Hdmi
Hi Andy, I was just interested in getting opinions on whether recording to an external deck was advantageous or not... Personally I hope we can hook the camera up to something like the nanoflash or Ki Pro Mini and get amazing results.

Yep sure - if the HDMI is "clean" as was so well put that that would be great (i.e. 1920x1080 and no red dot a la 7D!!). I guess we'll all know soon.
As an aside just had a quick look at your website - some amazing stuff you've done :-) EDIT: Just found this info on the Nikon site. 720p25 is listed....no 1080p25 though. Also, note the info (in the link) about the codec it uses. D-Movie | FAQ |
I guess I was too generous on the data rate. Best is 19Mb/s which is not great, based on the 2900 MB file size.

Is the movie function spec the same as the d3100 then?

What about exposure control in video modes?? Please let there be manual shutter control!!

Dear David,
If the HDMI output is clean, and the camera does a good job on downsizing the image to 1920 x 1080 or 1280 x 720, then a lot is to be gained by an external recording. But, these are big "If's". But, one day we expect cameras to meet these conditions. And when they do, the nanoFlash will be ready. The 12 to 20 minute time limit will be gone, a higher-bit rate can be used, and if one does not record in camera also, some of the heat generated while recording in camera will not be generated. More than one camera manufacturer is working hard to eliminate these "If's". In my opinion, it is just a matter of time. |
