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

[Bob Thompson]

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.

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

Sorry, just wanted to check.

Thanks.

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 \

[Chris Hurd]

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.

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.

[Steven White]

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.
