Crews.tv have offered up full resolution frame grabs of the unfinished AF100’s compressed 24Mbit AVCHD codec against 100Mbit AVC-Intra (the latter via the camera’s HD-SDI output). With Philip Bloom generating some excitement over the over-cranked 60p capability along with what I expect will be some knock out footage shot in London anticipation over the camera is high and it’s not even finished yet!
The .MTS AVCHD file comes direct from the camera unaltered.
I’ve made some of my Photokina GH2 prototype footage available for technical analysis.
You can download the footage from Vimeo here. It’s shot in 1080/50i mode (50p on the sensor).
It’s important to first note that this is prototype footage and strictly not representative of the final product. Also if you mention the footage or link to it from other places, please make this clear and credit it to EOSHD.com.

When the GH1 was released in 2009, for nearly a year we had a camera with a very poor codec until the hack situation turned this around. Footage would turn to mud on fast motion or whip pans, sometimes even gentle handheld shots depending on the lens aperture and amount of detail in the scene.
Update – the article has been rewritten based on my own tests, since there are conflicting reports elsewhere of whether 86Mbit is achievable or not, let alone reliable.
The new 44MBIT AVCHD is amazing in low light. It holds onto so much more detail at ISO 1600.
The GH1 needs careful handling and a great lens to perform at ISO 1600. You need to expose well, maybe a little over.
As the Panasonic GH1 Custom Firmware develops further, we now have quite a lot of options to choose from.
We needed a really good test. So what’s even more fearsome than a camera chart? A lama. That’s what.
Panasonic did a fantastic job on the GH1’s hardware, and it’s software is an impeccable creation, with really easy to use functionality. Now Tester13’s software PTools allows us to change a limited set of variables in the GH1’s firmware. It doesn’t recode anything complicated, create any new functionality or restructure anything. It’s simply doing this:
