One of the first things Sumix is going to add to their software is RAW recording so you can debayer in post if you want. Laplacian filter looks good. The others give a rather soft image but still good enough.

This is an uncompressed frame. Taken from the uncompressed AVI 8bit. I used bilinear as filter so don't expect much quality. I wanted speed.

Thanks Jose

That puts my faith back in the camera. I was debating using it for a feature shoot this summer. What lens did you shoot this test with?

Jumping into the thread...

Sumix looks quite nice from a sensor and programmability point of view... But theses are just part of a camera.
The problem I see is this cam rely enterily on the portable computer's power.
And you can't switch computer on/off constantly between 2 shots.. Specially, processing HD realtime require lot of power, so you won't last more than an hour when shoting outside, while with a regular camcorder you can stay the whole day outside with a single battery.
Plus, it don't look easy for steadicam shots to have a computer plugged without a single monitor onboard to see what's happening.
This camera may be perfect for studio shots, but otherwise...

Hi Robin,

I'm not saying this is the perfect HD cam for every possible project. This is not a RED One. In fact it's not a complete cam. What I'm saying is that this is a new and big step forward when you're trying to shoot something close to film in a controlled environment.

You say this cam depends on your computer's power to shoot. Well the same happens with a SI2K Mini cam and people are using it for professional projects. Of course they don't use it to shoot outside for a whole day. They can't. But that doesn't mean the SI2K Mini or the Sumix are not a very good option to shoot digital cinema. Plus the Sumix costs like $10,000 less.

By the way, who says you don't have a monitor for steadycam work? All laptops have vga out. Just plug in a little lcd and you've got your monitor.

Jose, thanks for the shots... I can't wait to see more.

With that 222 Wh battery pack your using, you should be able to at least match the RED One's battery life :)

Is that miniPC able to provide a decent preview of the shot, and record to the HDD simultaneously?

Keep up the good work!

isnt red one like 70W? thats pretty significant power drain. i have no doubt that a small pc or laptop suitable for use with sumix could pretty easily consume less power. i mean RED one records RAW data and provides something like quarter res preview (with what debayer?). recording a raw data stream doesnt take a lot of cpu power, compression and/or high quality debayer at high res uses lots of cpu power. recording with light compression and bilinear debayer at half res is probably something that can be done on what is nowadays a mid-range spec laptop. thats all SI is doing, so obviously it can be done, and i have no doubt it eats less than 70W. and SI could do it last year, this year CPUs might be considered to be about 30% more efficient than than the CPUs that were out back when i saw SI-2K at NAB last year. btw that minipc is just a rebadged aopen i believe ( http://minipc.aopen.com/Global/spec.htm ). mentions 90W draw, but that of course depends on the cpu, 90W max i assume is if you have 2 so-dimms, 2 pci-e cards, are using usb power, have both a HDD and cd drive that are spinning up, and are at full cpu load.

RED One uses about 60w with a 140Wh battery, and has 90 min of battery life on a charge.

The computer im planning to use is 52w under full load, its unlikely I will be under full load. The 7" lcd uses 8w, and the camera itself will use a bit more. All in all about 60w. If i'm doing my math right, I should be able to get up to a few hours off a single battery.

I've been looking at your footage, Jose and it looks like you might have a dead pixel in there, or maybe I'm misinterpreting what I'm seeing.

Power

Camera head only needs 2.5W at maximum frequency. We can supply a USB plug for supplying power to the camera head without needing to use POE. But you have to make sure the PC can reliably supply the 5 Volts and 500ma current needed, otherwise the PC can shut down randomly.

I highlighted the dead pixel in this clip: http://www.vimeo.com/845208

You have to download the original file to see it.

a steadycam like rig would be my dream for real life shooting
the camera head with optics plus
on a arm the panel PC with touchsreen
maybe in a brick another harddisk
and for balancing a battery block
the poor man read is ready

http://ipc-tek.de/product_info.php?products_id=247
all in one block very good in a..steadycam like rig

or even this

I just bought this:
http://www.cappuccinopc.com/slimpro-sp635b.asp

I picked the thicker one for the cheaper and faster 3.5" hard drive support.

SlimPRO SP635B (RoHS) (RoHS) (Black) (Qty=1, Price=$845.00)
- Intel® Core™2 Duo processor T7200 (2.00GHz / 4MB L2 / 667 MHz)
- DDR2-533 SODIMM 512MB (I will upgrade it myself)
- System with No HDD (Will buy my own high speed HDD)
- No Optical Drive (no need. only waste of power and noise)
- Onboard Video (good enough)

It may not be fast enough to operate the camera but its worth a try.
