Kaku Ito's XL H1 video clips -- here's the second batch
 

Howdy from Texas,

Play these on an HDTV display if you have one available. And if you can't view .m2t files on your system, try the free VLC player from www.videolan.org -- Enjoy!

once again the chroma aberration clip is dust - wonder if it is the ? in the title which causes the problem

WoW, great footage so far...crystal sharp with nice motion...still downloading!

Well, now that I have seen all the clips there is no doubt that Canon delivers great footage, but I think that I have stared myself blind with all HD content in the last 12 months. I think they all have theire look to the footage. I can see if it was shot on a Z1, HD100 or a H1, but they are all about equal depending what one is looking for!

You can clearly see that Canon has more pixels than the Sony but for the price diffrence I wouldnt go for the Canon. I dont think that the quality is that much better than the Z1/Fx1...and the interchangable lenses and some extra features doesnt justify the price diffrence...unless you really need them!

I still like the 24P of HD100 more than the 24F of Canon and I still dont know what makes the diffrence but for sure there is something!

I never jumped on the XL2 as the HDV´s had arrived and also if I had no choice but to shoot DV I would have choesen the DVX as the Panasonic 24P looked better than XL2´s. Now with all the HDV´s on table I think the closest to DVX 24p in HDV is JVC HD100´s 24P.

All cameras are great, just choose according to your taste of look and budget...and thanks alot for posting these clips!

For some reason these latest files aren't .zip files as the 1st batch were but end up on my mac as .txt files, but after deleting the .txt the play OK in VLC.

Thanks Kaku for all the hard work

I was not sure if the clip has the aberration problem and that is the reason why I put ? mark in the title and Chris can remove that if he thinks htat is right. I should recaptue this before i return the cam.

That's my fault. I asked Kaku to just send 'em as .m2t because the zip wasn't compressing it that much anyway. Sorry if I was being PC-centric with that; didn't mean to inconvenience our Mac folks.

Bob,

That is what I guessed because from the experience we had when I provided FX1 clips. This time, Chris suggested to send the file as is because we are experiencing a problem with the aberration file.

You are welcome and I'm glad you enjoyed then.

biketrick.m2t is soft either because of focus was bad, or aperture diffraction. I'm guessing diffraction. So far I haven't seen one HDV camera with auto iris that has a function to avoid stopping down beyond a certain point to avoid it.

One way to spot it is it will look like shooting thru something like a ProMist 2.

Be aware of stuff like this when slinging arrows...

[edit: add blacklabrador to that list]

If I'm not mistaken then all these and the previous lot of sample videos are HDV and not captured from the XL H1's HD-SDI port. Is that right?

Sorry, just wanted to check.

Thanks.

Dial -- everything from Kaku is HDV.

Nate -- this is one major difference between the XL2 and XL H1. The XL2 stops down to f/16 before closing. The XL H1 stops down to f/9.5 before closing. Diffraction is indeed a big issue with small-sensor HD, isn't it...

It's huge. I have stuff I shot last year with the FX-1 that I'm just realizing now is soft and furry because I wasn't paying attention. I barely knew what it was at the time anyway. And I didn't have a proper HD display. And so on and so on...

Actually the FX1 and Z1 have exactly that menu option, for exactly that reason. The choices are f/5.6 and f/8, IIRC.

Good news and bad news
 

Good news is that me and my staff at CreativeSuite are successful capturing some footage in DecklinkHD uncompressed 1080i format along with recording HDV at the same time.

Bad news is that the distributor didn't return the reflecmedia to us to be able to shoot green back. What a downer.

Great, this confirms HD-SDI output with simultaneous HDV recording. I figured it was possible but didn't know for sure. Thanks!

Kaku,

With the Decklink HD card could you see if it is possible to playout the HDV footage to SD via the SDI cable without any rendering necessary.

I was hoping to shoot HDV and use the Decklink card to downconvert via SDI to DigiBeta.

Thanks and keep up the good work

Bob,

This could be slightly off the topic, why don't you make a new thread and we talk about it there. I will do the testing for you for sure because that is my main experiment and I have both Kona 2 and Decklink HD at my office.

P.S. .....or you can join me at my blog talking about it since mac related topic don't so hot here at DVinfo.net. I had posted many topic relating to what you asked for buy hardly got return.

you have to register and confirm to leave comments.

To repeat, the chromatic aberration clip again has a bad link.

Dial,

uncompressed HD footages through the HD-SDI are coming later. I don't have much time left but we recorded playing guitars and the same cast riding down the street and I shot video from our second floor window. So, just dial in later.

Thanks Chris and Kaku for your replies.

Kaku, I'm looking forward to it. dewa mata.

Working on the rough edit right now.....hang on.....but it will take long time to upload....

I'm very happy to say that the night scenes put a smile on my face, that was very clean and noise free, the "nitefreeway" clips.

Just wanted to know what (if you remember) the settings was, did that have any gain?

Thanks Kaku for your hard work!!

Just FYI, in the Windows XP world just about anything is acceptable embedded in a filename EXCEPT * ? / or \

Just to be on the safe side, I have removed the "?" from the filename.

For John Jay and SVV, that clip should download and play just fine now.

For the nitefreeway clip, I was shooting with 24 frame mode and 1/24 shutter speed. I did some 1/48 but it was little too dark. Gain was set to 0, iris wide open.
Niteodaiba looses the focus on automatic in the middle, you can see how it looses focus in the dark situation.

One thing I noticed is that it was rather hard to find focus with the color CCD.

Chris,

I'm uploading a 1GB 1080/60i uncompressed file right now, you can cut it to make the download reasonable. It's a Kona 2 file. I think you can download the playback codec form AJA.

Kaku

Thank you Steve, I'm totally ignorant on Windows.

Thanks! I had been wanting to see the clip especially since today I take delivery of a new Panny AE900U projector.

I hesitated to really conclude and name the clip as aberration but Chris, is it really the abberation around the sun? or some classical flares.

Wow!!! That chroma clip is gorgeous.

As for the aberrations, the star shaped flare is a (rather pretty!) property of the lens itself. The rainbows you see around the flares are called "chroma fans" - also a lens property. The vertical lines you see associated with the flares are an artefact associated with how CCDs are sampled.

Chromatic aberration doesn't really occur in this clip until your completely zoomed out. (Aberration occurs primarily at the edge of the lens). Near the end of the video, look at the gaps between the leaves and the sky at the edges of the picture. Here you might see some slight green/magenta shifting at the edges of the leaves. This is the chromatic aberration, and it is really quite minimal. To escape chromatic aberration with this camera, always operate it at slight zooms.

-Steve

I think the 60i stuff looks much sharper than the 24F, and I think this is the work of a deinterlace algorythm!

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? ;)

Thank you for your great observation.
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.

This may have to wait just a short while -- I will need some outside help with this. My hosting provider will throw large, hurtful things at me if I make a 1GB clip available for public download. If there's an "Inner Circle" member here who wants to take a crack at editing this file down to 200 or 300MB or so, please contact me off-list by private email. I won't be able to work with it myself on this machine and my editing system is down right now.

Chris,

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.

John Jay,

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.

Hey Kaku

no worries

relax and good night

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.
