iSkysoft on Friday released the latest version of its video conversion program, Video Converter 1.8.1.0. The update adds support for MKV, WMV, MOD, ASF, MOD and MP2 input formats, as well as MKV and MKA output formats. The program allows users to crop video to remove black sides, trim the length of files, extract audio, or capture pictures while previewing a movie by pressing a snapshot button. Video resolution, frame rate and bit rate can be adjusted, along with audio sample rate, channel, encoder and bit rate.

The program can create files for a number of portable players, including the iPhone, iPod, Zune, PSP, iRiver and Creative Zen. HD video can also be converted, using TS, TP, TRP, or M2TS input formats.

Video Converter 1.8.1.0 requires Mac OS X 10.4 or higher, and is available to download for $35. Customers can also purchase the software on a CD for $45.
