Petite description in english :
Et meilleur pour la fin : gratuit, et disponible sur Windows uniquement.Convert nearly any video format to nearly any other video format with the aptly named Any Video Converter.
The program supports just about every video format known to man, including AVI, DivX, FLV, RM, and VOB. It also comes with output profiles for devices like the iPod and PSP, though you can easily create a custom profile with the audio and video specs of your choosing.
AVC couldn't be much easier to use, and it supports batch conversions--always a nice perk.
