Hands down the best (almost) pure x264 frontend on Windows at the moment. Would get involved if I had the slightest clue about Delphi.
Potentially a cool program, but it did not work at all for me. At the end of the encode I see a message in the log file saying output file cannot be found, and the output file is not present in Explorer. Initially I had a problem with the program halting before the end of the encode which the Event Viewer recorded as 'the reference assembly is not installed on your system' (VC90.CRT and VC80.CRT). As it is not possible for someone like me to identify the Visual C++ runtimes required I installed a whole package called Microsoft Visual C++ 2005-2008-2010 Redistributable Package Extended (x86x64). This allowed the encoding to complete, although unsuccessfully . There are no system requirements published and the properties of the executable does not specify an assembly version, but while uninstalling TX264 I noted in the uninstaller log that it installed files to a folder for .NET 4 which suggests that this program is for Windows 7/8 and not XP which I am using.
There are no 3 star reviews.
