Bytessence MPxConverter

Bytessence MPxConverter is a simple user interface for AMV-Codec-Tools, a fork of FFMpeg targeted at media conversion for chipods (cheap mp4 players, usually knockoffs of popular brands). It is based on the same code as the (discontinued) AMVConverter, but it now is compatible with both Actions and Sunplus players. The program kept many features from its predecessor, mainly portable code, ease of use, speed and multilingual interface while adding extended conversion support.

The advantages over the standard conversion tools are: faster media conversion, portability, multi-platform design and open source code. The only known issue for the moment is that the AMV files converted using MPxConverter are lower quality than the ones transcoded by the standard conversion tool. This is mainly because the The AMV encoder used in this FFMpeg build is in alpha stage.

If you prefer quality over speed for AMV videos then you should consider use the standard converter that came on the CD with your player. Any problems concerning issues other than this simple interface should be addressed here: AMV-Codec-Tools.

Frequently asked questions

Q: How to translate MPxConverter?
A: To localize MPxConverter you can open the file called 'English.ini' from the 'Localization\' directory of your MPxConverter installation and translate the lines. The files use the standard INI layout so you can use any raw text editor for translation (like Notepad). To make the job easy you can use IniTranslator, an open-source translation utility. After you finish, save the file with ANSI encoding. If you want to share it with other users you can send it in an archive at the support e-mail (see the contact page) and it will be published here.
Q: How to install translations?
A: To install translations, unpack the archive to a temporary location (like the Desktop) and copy the extracted .INI file to the 'Localization\' directory of your MPxConverter installation. After copying the file, restart the program if it was running then open the Settings dialog. At this time you should be able to see the name of the installed file in the translations box. To activate it, click the desired language in the list, press 'Accept' to save the settings then restart BMPXC.
