Possible location of video compression bitrates (AVCHD VBR) for HF100 / HF10 at offset 0x46BCF8 of decrypted firmware "VEE1-decrypted.FIM.code-4000000" (firmware decrypted using cail's tools)
For firmware decrypted using hf10x.exe (see 5 posts below), the correct offset is 0x66BD18
Page 36 of HF100 / HF10 manual states that the camera uses VBR (variable bitrate)
Bitrates are 2 byte Big-Endian. Example 0x4650 = 18000 Kbps = 18 Mbps
For simplicity, some of the values have been rounded off ...
Rec BitRate XP = 4650 3E80 3E1C 3DB8 36B0 08D0 = 18Mbps, 16Mbps, 15.9Mbps, 15.8Mbps, 14Mbps, 2.2Mbps
Rec BitRate HQ+ = 3584 2EE0 2E7C 2C88 2AF8 0B95 = 13.7 Mbps, 12Mbps, 11.9Mbps, 11.4Mbps, 11Mbps, 3Mbps
Rec BitRate HQ = 3584 2EE0 2E7C 20D0 157C 0B95 = 13.7 Mbps, 12Mbps, 11.9Mbps, 8.4Mbps, 5.5Mbps, 3Mbps
Rec BitRate LP = 3584 2EE0 2454 1A2C 0FA0 0B95 = 13.7 Mbps, 12Mbps, 9.3Mbps, 6.7Mbps, 4Mbps, 3Mbps
Rec BitRate SP = 3584 2EE0 1900 1388 0FA0 0B95 = 13.7 Mbps, 12Mbps, 6.4Mbps, 5Mbps, 4Mbps, 3Mbps
NOTE : As Wiesel pointed out, "A little problem with changing the FW and testing with it is (beside the big risk of bricking the cam) that you can only upgrade the FW if the version number is higher than the current one"
Risky guy (or someone with a broken cam) may try to increase bitrate to 24mbs ...
Best of luck.
