Downloadable HM700 night exterior tests

Here's a short sequence of various settings at night (2:00AM) under residential street lights.

Please right-click and download to your computer.

(193MB)

I rendered this sequence out in ProRes422 so if you have issues watching it in Quicktime then download and install the ProRes422 component.

Windows: Apple ProRes QuickTime Decoder 1.0 for Windows

Mac: Apple ProRes QuickTime Decoder 1.0 for Mac

Does it get any better at 3am?

How does this compare to your HD100 or other HD cameras that you have? Just by looking at the type of street lamps that are there, I would venture that my HD100 would do about the same, maybe a little better. How is the grain at +3dB?

Well here's my HD100 test shot under similar conditions way back in 2005.

Sorry... skipped +3dB and didn't bother including +12dB (which was noisier than I would probably acquire)

With my day job and NAB around the corner I don't really have time at the to shoot comparisons of the different cameras. For the moment I'm doing my own testing and sharing what I think will be of interest. Maybe after NAB I'll have some more time.

BTW if I were shooting in streetlight conditions and wanted the lowest noise with maximum exposure I would likely use the Filmout Curve at MAX on either 0dB and 1/24th shutter or +3/+6dB at 1/48th shutter.

Now if you want to see something interesting... take the +6db filmout version into After Effects, and try running the Neat Video noise reduction filter on it. I'm just running the demo right now, but it's pretty amazing what the footage looks like after getting the noise reduction.

I'd like to see that if you can output a still and attach it to your post.

Are you sure you can't shoot at 3am? And can you get that running woman again?

Thanks for posting the HM700 video and directing me back to that HD100 clip from 2005. Forgot about it. I haven't had much call to shoot in the street at night so my experience with the HD100 is limited in that regard. That 2005 clip, while shot in what seems to be a slightly brighter area of the city, sort of indicates that the HM700 is less sensitive.

Here's one better - here's the render with the demo plugin. It only renders (in demo mode) the center 640x480 area, but it's more than enough to get the point.

No CC or anything done to this other than bring the ProRes file into AE, run the Neat Video plugin, and output as JPEGs.

I had a hell of a time trying to upload an actual video of these files - even if the .mov was only 1.1 MB. Any suggestions? It's obviously best to see it in motion.

DV Info switched to a faster server last night. You must have been here during the transition. Everything should be re-linked now.
