First test footage: HD with GG orbiter

Les Dit · August 12th, 2004, 01:27 AM

Brett, I need to sort out my bandwidth on the server I use, but I will get that video to you. You wern't one of the 150 that looked at the video ? I still can't believe how many lurkers there are on here !
And how many that downloaded both the mpeg2 and the media9 ... what the hay, greedy little buggers ! ;)

SOOO .... How abouts you post up a little sample for all to see?
I'm the only one that posted a video at high quality so far.

ps: anyone remember where that pdf is with the mini35 pictures? Some folks are interested in the workings.

I'll post a video when Im all done constructing it. It should really be something to see even compared to the Mini35 itself.

Daniel Moloko · August 12th, 2004, 02:06 AM

brett,

its easy for you to reproduce this Unity?

or send the exacts plans?

im really need one of these...

you people got to help me!

Hello.

I'm one of those lurkers.
I did not reply since my knowledge about these things are so low.
I do have a few questions though.
What is causing the flashing of the light in the lower left corner? Also, is it just me or does the image vibrate a little?
The DOF is damn cool though and there seems to be less noise (chroma noise I think it is) than in other JVC HDV clips I've seen, did you use some filter for that?.

Best, Magnus.

Sigh...

I'm waiting on southern Mississippi to figure out what broadband is, so that I can post some high-rez motion footage, instead of sequential framegrabs.

;-)

Les Dit · August 12th, 2004, 12:42 PM

The framing was off a little, and the camera was seeing too much of the left part of the GG, so you see the edge of it moving. The camera was just loose, so I could move it around, The bottom left flicker is the counter weight. There is a bit of image vibration, the mount needs to be made of something sturdy, not the temp wood setup I used to hold it up for the test. I did run a virtual dub chroma filter on the footage, yes.

My bandwidth limit gets reset on the 16th, I can mail links to the HD video test after that.

Brett...how small is your unit now? do you think it could be built inside a camera or will it have to be outside the body?? I would like to design our camera around your system so that you never take the GG adaptor on or off...it's part of the body

Richard Mellor · August 12th, 2004, 09:12 PM

les thank you for the clip. I have made a agus 35, and a aldu35
this looks to be the most promising .

Les Dit · August 12th, 2004, 10:28 PM

Remember guys, It's not really Brett's system, or my system.... it's Pstechnik's .
Brett, what is the diameter and depth of your module? My 3 shaft one is 1.5" deep and 3.5" diameter. Did you try a 4 shaft design? I think that saves room for a bigger GG. That size doesn't include the motor, it fits outside the main diameter.

Brett Erskine · August 13th, 2004, 03:01 AM

My GG is aprox. 60mm square and the off set shafts make it move in a 2-3mm circle. With this said it isnt a option for a in-camera system but if you plan on using only 35mm lenses then you could make it small enough to be in camera.

Im hunting for a slick looking project box for it right now. In the mean time a regular one will do. The bottom of the box will have a section where you can run a standard 15mm rail system thru so you can mount it properly - not to mention run a follow focus set up.

Brett I really want to test your GG with the HD camera I am working on...how can you help me out? I could test it for a week? or?

Les Dit · August 13th, 2004, 11:05 PM

The shots look like they use the DOF effectively. They do look a bit soft, maybe because it's a proxy or something.
I have yet to shoot a res target with mine, with and without the DOF gadget in place. I think it does loose a touch of resolution however. I think the before and after resolution of these DOF things like the one I made should be part of the testing for effectiveness. MTF is MTF and DOF shouldn't impact it too much.
Sometimes low budget filmmakers get fooled into thinking that softening the image is part of the 'film look'. Film isn't soft. Interesting dilemma!
