Review by 龙大侠 on Dec 26, 2017 Version: 6.02 OS: Windows 7 64-bit Ease of use: 10/10 Functionality: 10/10 Value for money: 10/10 Overall: 10/10




Good free option to use for an intermediate format.
Works great with 4k and UHD.


Review by newpball on Jul 21, 2015 Version: 7.31 OS: Windows 8 64-bit Ease of use: 8/10 Functionality: 8/10 Value for money: 10/10 Overall: 8/10




Superb intermediate intraframe codec. Win7 or 8 only. Doesn't work with XP or Vista. Easiest to use with Grass Valley AVCHD2HQ converter utility (also freeware from Grass Valley). Works well with Virtualdub.
