Hi Tester,That`s a pretty interesting comment!..what have you discovered/seen that makes you say this,in other words what`s the potential of GH1 in relation to this statement that you hadn`t seen before? :)

Today we are like blind kittens.
In reality we need either debug firmware build or object files (they won't provide sources anyway). Speed will be much faster and results will be better.

We must build small team with sole purpose to reach necessary people in Panasonic Lunix division development department.
Under this I mean information digging, many calls via cheap international Skype, etc. to get necessary persons and talk to them.
I do not mean any useless petitions, etc
Contact me by email and PM if you want to become member of such team.
I specially invite people from Japan.

Hope you can get this off the ground and that Panasonic can see how this could put the GH1 into legendary status and sell so many more GH1s!

I can't do all myself.
Problem is very little number of people understand it.

I want to emphasize that this project can stop without information and tools.

And we really need Panasonic compilers (they are provided with any AM3 based controller).
Plus first hands information.
I really mean very many calls and collecting all contacts is special database.
We can start from: http://panasonic.net/corporate/segments/sc/

If you passively read this thread, it is time to join!
Contact me at info dot pentax-hack dot info.

Maybe this should be our next buy item. Seems more important than getting a G-1 or GF-1 body. Did a little research and found this:

I have not been able to find the price of the AM3 development board, but the AM1 board can be bought here:

http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=MMK01-C78-ND

This is available for $358.50. It includes the C compiler and the debugger, but may be locked to the specific MN101 processor. I will continue to try to search for a MN103 development board.

Thanks Tester13 for your efforts!

We already have these bodies, and don't have any need to buy AM3 board.

I know about this guys.
You can ask them for evaluation versions of compiler.

First, we don't need AM3 board.
All we need is code provided with this board.
With htis code I'll be able to download compilers myself.

As I specially outline - C and ASM compilers themselfs are not enough, we need to establish good contacts and get as much information as possible.
And you don't need to be programmer to help in this areas.

I understand that you only need the code to activate the compiler. The only legal way to get the code is to buy the board. I have experience with this for another type of microprocessor. Full versions of the compilers for professional use are very expensive (sometimes $10,000). But, when you buy a devlopment board, they throw in a version of the compiler for "educational use." There hope is that you end up deciding to make a product with the microprocessor and later need the full compiler version. You get a simplified version of the compiler for next to nothing ($358). Only way to get this compiler for little money is to buy the board.

Any other way of obtaining the compiler activation code is software piracy and I thought we were trying to keep this project clean from a legal perspective.

No, it is not piracy, as DebugFactory can be distributed freely according to license and evaluation compiler versions can be also provided to any third-parties without problems. This is exactly that we are doing.
 
class 10 card

class 10 card

Been testing NURBS settings of:

[ Quality settings (E1 to E4) - 720, 512, 428, 400
Table settings (E1 to E4) - 24, 24, 24, 24

Bit rate : 77 Mbps <- Nice result ]



Amazing mjpeg performance. However my Kingston 4gig class 6 wasn't fast enough for high detailed shots. I got a message informing that my card wasn't fast enough.

What Class 10's are good?

those settings are pushing the limits of class 10 cards. 77mbit reaches upward pas 9MB/sec. I'd look at Sandisk Ultra's II or III's to reach those writing speeds.

Thanks.. Is there a difference between the Ultras and class 10, as in their speed?

BTW the quality is phenomenal at that speed. I shot some quickies with the anamorphic, which softens the image a little, and missed the focus a tad. However no codec artifacts at all. Amazing!

Here's are a few frames from the 1920x812 upscale from the 720.

On the issue of SD cards needed for these write speeds...

Has SanDisk dropped the numbered levels of their Extreme cards? I notice tester13 is shooting to get a SanDisk Extreme III 30MB/S 32GB SDHC... but upon looking it appears the newest sold models are simply SanDisk Extreme 30 MB/S. http://www.sandisk.com/products/dslr/sandisk-extreme-sdhc-cards--

Furthermore, I found a website or two that displayed the "SanDisk Extreme III 30MB/s" specifically.. and I noticed a "Class 6" rating for some reason. http://www.mydigitallife.info/2008/08/29/sandisk-extreme-iii-sdhc-30mbs-edition-cards/

Was the "Extreme III" cards simply last years branding or is there still any quantifiable difference between "Extreme" and "Extreme III"?

I think SanDisk Ultra is specifically their branding for their midrange Class 4 (as appose to standard Class 2) cards... which SanDisk selfrates at 15/MBs. Their newest Class 10 Extemes are rated for 30MB/s... with older models I believe rated for 20MB/s and some labeled Class 6.

Ive juggled with how the Ultra rate their speeds before and debated it, but I think it was simply before the industry "standardized" how class ratings were rated. Ultra's seemed to be ahead of the game with their II's and III's rated at 15mb and 30mb, but that's also read/write speeds not necessarily write. If there's a difference, yeah, I think so. Their class 10 and 6 are faster than industries class 10's and 6's. In reality Ultra II are like class 15 and Ultra III are like class 30.
 
Get the bench test program, ATTO Disk Bench mark, then you can be sure.
I bought an el-cheapo Class 6 card.
In the bench test, the read and write speeds for 32kb upwards to 8 mb were above the 10 MB / Sec...
