Nate Weaver and Tim Dashwood have some beautiful 24P and 30P footage that are sharp yet filmic, and the motion isn't particularly strobe-like, whereas everything I've seen from deinterlaced footage has gone ever so slightly soft and stuttery. I guess the difference is what happens when one designs a Progressive camera from the start, vs the video oriented XLH1 and Z1. But that XLH1 lens... Phew. Now, how can we bolt that onto the HD100, I wonder? ;) |

It seems to be hard not to use the widest angle since the standard lense does not give you wide enough view! But it is good to know how to avoid it. Thank you Steve. |

If that is the case, it is faster for me to cut it out. I will work on the file tomorrow to make it shorter. If anyone want the clip as soon as possible, they can download it from my site. |

No problem Kaku, I realize 200-300 MB is not much time for uncompressed video but I really am forced to keep the download file sizes manageable. Sorry about that,

Is this not the same clip as before but longer, with the parrot chirping in the background?
I was hoping for some reflected light tests such as from a checkerboard especially at widest aperture where all the problems are likely to be. this pinhole aperture F9? shows a lot of smear and also the pattern of the microlens array which is bonded to the CCDs. would like to see more aggressive testing of the lens, but I guess that will come in time, no doubt.

Yes, rest assured that formal tests in controlled situations complete with charts, etc. will come later. For now please realize that these particular clips are simply the result of Kaku Ito being very generous in sharing his limited time on the XL H1 with the rest of us. This was never intended to be a formal study. He had the camera on loan for a short while, was able to shoot a few specific things for us and also had his own requirements to take care of. This is not a formal "DV Info Net Case Study" but simply the generous input from one of our members in Japan who was able to put his hands on the H1 for a short period of time. The man has other things to do as well. Don't worry, we'll pursue all the H1 bench-testing you can imagine as the camera becomes available more readily.

I'm sorry that I could not work on the aberration test, but it threw me off that the 24 frame portion of the tape could not play with Sony cams, that limited my time to shoot more. I thought that even bikeseq files showed the problems, I thought it seems to have the problem already and not necessary to do the test. I guess it is obviously you wanted to see the poblems in diffeent degrees. I hope Canon would provide me the cam again for a longer period to do that test for the next time. |

I am a visual effects student currently in college. I like to do lots of blue/greenscreening. I found HDV from the Sony to be unusable as there are waaay to much MPEG artifacts in high motion scenes.
I expected the same from this camera, but upon watching the clip of the guy on the bike, I can find very little artifacts, even when viewing the chroma channels on their own. How is Canon able to do this? It should have the same artifacts as the Sony, right? But it doesn't. It looks fantastic. I am in awe. Last edited by Daniel Broadway; October 3rd, 2005 at 04:17 PM. |

Can someone point out which clips are specifically in 24f mode, I'm not really that interested in the others and I don't really wanna waste time and bandwidth on downloading clips that aren't 24f

What kind of camera work do you wanna evaluate? Maybe I or other members can recommend a right file for you. |

Low light my friend, low light. Try to shoot some stuff just under street light (around 60 lux). Low light seems to be the acid test for 1/3 high def cameras.
It seems the H1 will suffer the same smearing the JVC does. I've noticed it in the CA shot. I'm looking for a similar split screen in the H1 as well at low light. Let's see how it performs 24F @ 40-60 lux. Kaku Ito, are you using the ND filter on the outside shots normally? The reason I bring this ups is because the waveform shows the highligts pegged for every outside shot. Click here to see what I mean I think all the 1/3" HD/HDV cameras are going to suffer in some way, merely because of the size of the chips. Pick your poison. |

About ND filter, I use it according to the situation. In this case I wanted to get more of the things in the shade to be seen, so I might have made it little brighter. or anything to do with 0IR setting? |
