HD-100 online clips montage wmv and DivX
This is for people who haven't seen anything from the HD-100. I made a short montage showing some clips and screen captures of footage gathered from the web. I have worked with all posted clips (that I could find) but not all clips are in the montage. The footage has been easy to composite, color correct, scale and do title composites with. Great quality and I expect the camera, in the right hands, will be a great tool for aquisition.
Click here for wmv Click here for DivX 6 Sorry Mac guys, no H.264. Quicktime 7 Pro still does not work quite right on Windows. I posted DivX for you. I do not own an HD-100 and have only worked with the supplied clips. The m2t's speak volumes to me in the quality that can be obtained. I have other composites and video test. If anyone cares to see them, let me know... Last edited by Stephen L. Noe; September 23rd, 2005 at 10:11 PM. |

Thanks for doing that... but the page is no available! Can you also post a version with no color correction?

I am on a Mac and my Windows Player v.9 won't play it. It says it doesn't support the codec that was used to compress the file. The VLC player cannot play it either. Any suggestions? Thanks.

Stephen,
Feel free to use any of the "available street light" clips in my public folder. http://homepage.mac.com/timdashwood/public I haven't published the results of this impromptu test yet, but all shots were only reading 2 footcandles or less. I've been experimenting with gamma curves and trying to obtain +12dB equivalent exposure in 0dB. Things are VERY promising so far, but there is more work to be done. Tim |

Mac guys and gals,
I posted a DivX encode at the top of the thread. I hope you can view it. QT7Pro still has 'issues' with Windows XP right now so no H.264 encode available yet. Sorry.. Quote:

Tim,
I checked out the m2t's. First the good news. I didn't see any split screen effect and the black level was consistent across the entire frame. I brought the black low and mid up just to see how much noise there was in the picture at 0 db and it was very even across the board noise wise. Your street lights do not illuminate to 60 lux do they? What was the lux on the street shots? All in all it was a decent showing. Second the bad news. The CA is overwhelming on the street shots. I did a selective color correction to desaturate the CA and the street scenes evened out. I can't see using the stock lens at low lux, can you? Last edited by Stephen L.

I have no idea how to measure lux. "Damnit Jim, I'm a DP...not an engineer!" I use footcandles. The incident light reading for the guy's face was under 2 footcandles. How many lux is that? The needle on my lightmeter barely moved. Quote:
Real CA is much more noticable on well lit scenes with any straight lines near the outer edges. The one thing the DVX does handle much better is the "vertical" streak. The denser the pixels, the more streak. This is one big disadvantage of 1/3" HD CCDs, and care must be taken to avoid hot spots. Here's the HD100 flaring from headlights (I also noticed some split): http://homepage.mac.com/timdashwood/...0_flaring2.jpg Here's an indirect hotspot on the HD100: http://homepage.mac.com/timdashwood/...0_flaring1.jpg Here's some weird stuff happening on hot spots on the DVX100 (notice the bad 4:1:1 colour sampling on the red tailights): http://homepage.mac.com/timdashwood/...ing/DVX_CA.jpg Here's the DVX flaring at +12dB. Very controlled vertical streaking. It almost looks like they have a cross/star filter built in. http://homepage.mac.com/timdashwood/...flaring+12.jpg |

Hi Tim,
Here is the formula to change footcandles into Lux: 1 Lux (lx) = 1 Footcandle (fc) x 10.76 In your scenario you listed 2 footcandles which would be approximately 20 lux. That is very little light. BTW: Click here for light formulas I thought maybe I'd looked at the street images incorrectly. The white balance has led the entire frame to be purple. I did a 2 point gray balance on the frame and it got rid of alot of purple and the images seems alot better. The cityscape shots do display CA though. I couldn't get rid of it with a simple gray balance. Click here for DivX AVI of white balanced image All in all it's a great showing for 0 gain @ 20 lux. It certainly is fun working with these images. Fantastic camera... Last edited by Stephen L. Noe; September 25th, 2005 at 07:41 PM. |

Tim D,
It'd be great to see the clips! |

Tim, I know you've got a lot of stuff online... if you ever need any help with hosting clips, I'll be happy to make some DV Info Net server space and bandwidth available to you.
