Ever since the GH1 was hacked, countless people have been shooting MJPEG when they’d get better results with AVCHD. It is really a shame to see all these projects shot in 720/30p with moire and noise, then they could be done in lovely true 1080/24p at 40+Mbit with a well resolved image.

GH2 hack footage – 42Mbit AVCHD 1080/24p

The GH2 is already a lot of bang for the buck. This hack has made it a bonafide plastic explosive!

In the latest hack released today Vitaliy has enabled high bitrate AVCHD in 1080/24p cinema mode for the first time. These represent the first image quality improvements for the hacked GH2. What does it look like? Watch the video above to find out.

Vitaliy hacks ‘photographic’ looking 42Mbit 1080/24p AVCHD out of GH2

Hacked GH2

Codecs are currently the biggest weakness of DSLR video but that is about to change, and no – not with an external record but inside the camera.

The hacker Vitaliy Kiselev says he has had ‘a break-through’ – raising the AVCHD bitrate of the hacked GH2 to an average of 42Mbit – almost double the original Panasonic specification and higher than the top AVCHD PS setting of 28Mbit. And unlike the GH1’s encoder, the GH2 has B-frames making it more efficient, so for the same bitrate it delivers more image quality than other DSLRs in the 40Mbit ballpark like the Canon 5D Mark II.

Vitaliy says on his forum that the video looks ‘like a photo’ in terms of quality. The next PTools release containing the patch is due out soon.

GH2 hack testing – initial report and how to test

Thanks to a leaked firmware update and Vitaliy Kiselev we now have a GH2 hack to experiment with. It’s very early days so don’t expect anything drastic yet. The AVCHD encoder is very different to the GH1, so a lot of testing needs to be done before the right parameters and patches are discovered that improve image quality and functionality.
