No no no -- the codec hasn't changed how the sensor works! It still aliases, and still benefits from some softening. I shot most of my stuff at f/8 and f/11 and the diffraction helped to minimize some of the aliasing, but the detail is incredible.
It's vastly improved, but at heart it's still a DSLR.
I think what it's done is set itself definitely above the Canons now. It's sharper, without the chroma moire, and it's got no mud, which was the real knock against it.
And it's still $1200 including lens. Huge improvement, but at heart it's still a DSLR/still camera and so it will still be affected by those things that affect DSLRs.

Just did Kholi.
As to cards, as I told Kholi in a PM. Go Extreme 8gig. I bought mine at Best buy overpriced. 74buck if I recall. I know there were II III, Those seem to have been changed out. The best cards are important at these data rates.
Also, if we could get a SDdummy card with ribbon cable to Compact flash. If such thing existed, that could interesting.
Out of here to shoot tests----------->

As I said, You need to shoot some wide shot detailed footage( use tripod) and compare AVCHD 1080 and MJPEG 1080...
As for upscaling; look at NURBS test
Very interestin thing too:
MJPEG mode let do change resolution ;-)
Duration : 10s 80ms
Bit rate mode : Variable
Bit rate : 28.9 Mbps
Width : 2 048 pixels
Height : 854 pixels
Display aspect ratio : 2.35:1
Frame rate mode : Constant
Frame rate : 25.000 fps
Bits/(Pixel*Frame) : 0.661
He got squeezed image. I suppose that is not true 1080, it's 720 upscaled output from sensor.
We need much more testing to achieve true 1080 __Mjpeg, if it's possible?
Resolution test that I made with Andrew settings (MJPEG) are not even close to 1080 AVCHD....
+ 2GB Size Limit
+ FPN in Shadows in MJPEG
+ Card limit with high detailed scenes
+ 60p
+ 24p

Those settings are not good. They failed in my testing.
How's this, it's all gravy.......We should have all options 1080/720 30/24fps and AVCHD/Mjpeg. All these tools have there rightful place. Would you agree?

absolutely....
Then let's all vote and donate to get them enabled. I would greatly appreciate a Photo JPEG @ 1080/24 along with my AVC-HD @ 1080/24pN. I feel as though I could use the AVCHD for commercial, videography, etc and the Photo JPEG for all of my narrative work.
This is turning out to be just as exciting as the GH1's launch.
Good times.

Just because I've been super curious, and had an hour to kill, I decided to do a comparison between my 5D Mark II and my GH1 with the new AVCHD codec hack. These images below are 100% crops from 1080p24 material.
GH1 w/ Lumix 7-14mm f4 shot @ 14mm, f/11, 1/80
5D mark II w/ 24-105mm f4 L shot @ 24mm, f/11, 1/80 (levels boosted in post because it was way darker than GH1 shot)
GH1 w/ Canon FD 50mm f1.8 shot @ 50mm, f/4, ???? (forgot shutter speed for these)
5D mark II w/ 24-105mm f4 L shot @ approx 90mm, f/4, ????
I'm really amazed in this one at how much moire there is all over the frame in the 5D shot vs the GH1 - the more I look at it, the more I find! ~note to self: stop pixel peeping...

Good giggly wiggly those are impressive results for the GH1!

That would be absolutely fantastic. It would make the GH1 an awesome little beast at last. So far an incredible job by tester13 and all the brave testers out there. Thanks a ton.
You guys are all over this. Great to see people getting good results.
Guess who just rejoined the GH1 family?Uh-oh...I'm leaning towards buying a lumix 7-14mm instead of a 7D........
I was half-a-hair off of getting a 5D again... That would be the only thing to push me to Canon territory at this point, the Full Frame sensor.
I'm thinking the same as you: about to purchase a PL mount and gonna roll with an 11-16/2.8 Tokina or a 7-14mm Vario real soon.
So happy to have this little beast back in my hands again.

Tested AVCHD 60i vs. 24pN, and yes, no question, the chroma is recorded much better in the 24pN mode.
Question here though is: why did it do that on the Pappas settings, but not on the other settings? Weird.
I missed this earlier in the running river of posts. Barry what setting did I send you that didn't do this?
. So the new is doin that. I saw this, however chalked it up to sensor. Now looking back at other settings test,it's absent. I need to re-run the numbers and test.
