之前笑恒发过一个关于GH2破解的测试样片，GH2 破解 AVCHD INTRA 220Mbps+ 测试样片 红石榴。
Vitaliy Kiselev发布他的最新版本3.63 GH破解，删除了ISO在视频模式的限制。可以达到惊人的ISO 12800，而且噪点颗粒表现也很好。看起来不像数字噪声，更像是8毫米胶片 ISO 800。
1. The high bitrate hack, be it 44Mbit AVCHD or 176Mbit AVCHD All I-frame allows the fine grain of the noise to be maintained and not smudged, furthermore it allows an incredible amount of resolution and detail in the image to be maintained.
2. Switching the camera to Dynamic B/W film mode reduces low contrast areas of the shot and electronically boosted shadows where noise tends to be most intrusive. The results are stunning, it is like having night vision or Infra Red. Blacks are a little crushed but at this level of exposure it doesn’t really matter – just over expose slightly.
3. Lastly the sensor scaling has a lot to do with it. At 1:1 the image would be hideously noisy but since a full 16MP sensor is being scaled to 1080p grains of noise are absolutely tiny making noise look more organic and film like. Also due to the nature of the CMOS sensor, brighter areas of the image are virtually noise-free if you use a fast aperture.
