High Definition with Elphel model 333 camera

[Jose A. Garcia]

Isn't real film shot at 1/48 shutter? If the sensor reads the frame fast but keeps "adding light" for 1/48 of a second wouldn't it result in more motion blur?

I'm also very interested in getting filmlike motion blur with the Elphel cause I'm using the same micron sensor for my project.

[Wayne Morellini]

The method I mentioned allows everything to be done. Dropping every second frame gives the conventional film look for 25fps HDTV, slowing 4% gives conventional film look, ever drop framed can be used to smooth out the motion at 24/25fps. Using all the frames gives an ultra-smooth 50p HDTV or digital Cinema, or interlace frames can be easily extracted, allowing for distribution across all formats with the minimum, of image recalculations. The issue is, what is future proof? At 720p50 it can be done in 100mb/s, 1080p50 would need an bit more. At the moment, he industry is waking up to 50p/60p (and 60p HDTV should be able to display higher quality 50p).

An month without an post, you guys are never that quiet, what's happening?

[Matteo Pozzi]

maybe all of you are on holiday!

or maybe someone is gone to another project? ....New DIY HD Cinema Camera Project??

for me I'm here and I'm looking on the net for good medium format lens to use with my next adapter :-)

Hey, I still take a look at this thread from time to time. The Elphel's the only one that can do what we can't do yet. Deliver an already compressed stream to the computer. Data rate's not as large as uncompressed raw so recording to disk is possible.

They're also using the same Micron sensor we were testing, so we know image and motion are just great. Very filmlike.

I hope Andrey's still working on it.

[Steven Mingam]

Last activity in the CVS was 7 days ago, so yeah they are basically updating the code every week...

[Matteo Pozzi]

I've found on the net this sensor ...is a strange one is square global shutter and is very big http://download.cypress.com.edgesuit...upa_4000_8.pdf
if it is not too expansive maybe can be used for the next elphel

[Jose A. Garcia]

I think that's the one Cypress offered me. The guy didn't say the reference but he said it was a big global shutter sensor that was able to do 2k 2.39:1 at 24fps. He said it was a bit pricey too.

1750$ :whistle:
I don't know if it's the nude sensor because it's in the evaluation kit category but yeah, "a bit pricey" ;)

[Jose A. Garcia]

That's just the sensor. I've read somewhere the price for the whole evaluation package is like $5000. Anyway the guy from Cypress will send me a price list on monday.

[Matteo Pozzi]

wow 1750 dollars only the sensor
compared to the micron that is 33.19$
....if in some year it will be taken for cheap
I think that this is what we need...
no adaptor 35mm sensor size and the possibility
to "shift the image" like some very expansive lens
....full to control vertical architecture line distorsion :-)
(this can be made already but with less benefit cause the size of the sensor)
and all in camera maybe it can be adapted to the elphel 353
and with these spec. :-) it will rock

It is also much cheaper and smaller than what is being proposed over there, more comprehensive. You are looking at the a size very close to the existing small box (handheld).

The Micron, I don't like the quality, an few years back it was obviously inferior to what else was available (but not an FF Ibis5a relying on internal ADC) but we can only hope that the modern micron binned to 720p can accomplish something.

The Lupa sensor is probably not available at an cheap price, it was monochrome only requiring an expensive for color. They mention it is available with color mask, maybe it has changed. Altasens is an better choice I think, they have an increased range.

[Jose A. Garcia]

Altasens doesn't support small projects. They were my first option.

[Oscar Spierenburg]

Yes, this thread is a bit quiet lately.
I have the 353, but I just want to get started on it when I 'really' have the time.
I think within a month I can spend all my free time on this project again.

Andrey was (or still is) in China for the development of some parts, so it seems quiet, but there's probably allot going on. I'll be shooting another test in the middle of France the coming weeks, but I'll probably use the 333, because I don't have portable power or a power transformer for a car battery yet for the 535. I don't think I have an internet connection in France, but if I do, I'll post what I'm doing.
I think the Elphel still is the most promising camera for us 'alternative imaging' filmmakers.

Yes, I know, I tried to talk to them ages ago, but you can go through their agents, like hanvision. They are producing an number of different chips in the background, apparently, and so you can find cameras based on them. Foveon should be getting an move on, to go big and license more, before their patent worth runs down.

The Elphel is still the most promising, but converting an still or webcam, or doing HDMI on something cheap, is still desirable.
