I have been doing many hours of testing and measuring with the different types of recordings made with the GH2. I have one GH2 with the original firmware and one with the hacked firmware, both that can be connected to the Atomos Ninja.

I will post my findings in a number of future posts, but want to make one important fact clear.

People have asked me several times if the hacked avchd footage is better than the Ninja recorded footage, and this is my answer:

The Ninja recording still dwarfs the GH2 avchd, even the hacked version. There is a lot of  processing going on before it reaches the codec on the avchd part and the hdmi signal follows another path through the camera’s hard- and software.

I for example can understand if panasonic has digital lowpass filters installed in their 10-to-8 bit conversion, because that’s what you do when downsampling to another bitrate.

You can hack the camera’s codec, but should look further down the processing line.

It’s a bit simplistic to think that you can upgrade a camera’s quality by just raising the codec’s bitrate; you’ll need to upgrade the limiting factors along the processing line all down to the sensor.

I’m afraid that there are also hardware components involved that can’t be hacked.

More news to come…

Many people have written to congratulate me on the new anti-moire filter plugin. Thanks everyone for your kind words and donations!
Your recognition and support are very much welcome and appreciated, specially now i am going through difficult times financially 😦

Several people have also written to let me know, that the anti-moire plugin also clears AVCHD compression artifacts and noise from e.g. Panasong GH1 and GH2 footage!
I’ve tried it myself with low-light/underexposed footage supplied by Mary Wiegant, and indeed! Even with a minimal filter Choma Blur setting of 3 to 5, large swarming color patches magically clear up!

Free lunch everyone! Bon apetit!
